Field beans will grow on virtually any soil in Manitoba; however flat, well-drained land, free of stones, is ideal. Beans do not tolerate standing water. On average, moisture is adequate across all of Manitoba for producing beans. Beans are a warm-season crop. Field beans can be generally classified as either bush or vine types. Bush-type varieties have determinate growth patterns making them suitable in solid-seeded narrow row production systems.

Crop storage humidification & humidity controlVIDEO ON THE TOPIC: Postharvest Loss: Storage in English (accent from the USA)
Food Security. Many environmental factors constrain the production of major food crops in Sub-Saharan Africa and South Asia. At the same time, these food production systems themselves have a range of negative impacts on the environment.
We summarize current understandings of the environmental impacts of crop production systems prior to crop production, during production and post-production, and emphasize how those initial environmental impacts become new and more severe environmental constraints to crop yields.
Pre-production environmental interactions relate to agricultural expansion or intensification, and include soil degradation and erosion, the loss of wild biodiversity, loss of food crop genetic diversity and climate change.
Post-harvest environmental interactions relate to the effects of crop residue disposal, as well as crop storage and processing. We find the depth of recent publications on environmental impacts is very uneven across crops and regions. Most information is available for rice in South Asia and maize in Sub-Saharan Africa where these crops are widely grown and have large environmental impacts, often relating to soil nutrient and water management.
A concluding overview of the emerging range of published good practices for smallholder farmers highlights many opportunities to better manage crop x environment interactions and reduce environmental impacts from these crops in developing countries. But there has also been growing concern that farming practices themselves, both in extensive food crop production systems found widely in Sub-Saharan Africa and intensifying systems common in South Asia are exacerbating biotic and abiotic constraints on food production through negative impacts on the environment Poppy et al.
This paper reviews the current body of knowledge on a broad suite of crop x environment interactions, including both the constraints on crops imposed by the environment and the impacts of crop production systems on the environment. We summarize environmental constraints on crop yields including poor soils, water scarcity, crop pests and disease and impacts of crop production on the environment such as soil erosion, water depletion, pollution and pest resistance at three stages of the crop value chain pre-production, during crop production, and post-production.
Constraints and impacts are then reviewed separately for each crop and region, using publication analysis to assess the relative severity of crop x environment interactions and the quantity of recent research on crop environmental impacts as reflected in the published literature since Future areas of potentially high value study are suggested given the importance of the crop, the intensity of the crop x environment relationship, and the depth of what we currently know and do not know in the literature to date.
We conclude with an overview of good practices from the literature and from expert experience for overcoming environmental constraints and minimizing negative environmental impacts in smallholder crop production across regions and farming systems.
By synthesizing the available evidence across these important crops, and emphasizing the feedback loops inherent in agro-ecological systems, we seek to provide a framework for stimulating across-crop discussions and informed debates on a range of crop x environment interactions in agricultural development initiatives.
This work can help research planners, policy makers and funding agents have a better understanding of environmental constraints and impacts associated with food crop production practices, and a better appreciation of established good practices to overcome constraints and mitigate impacts. Production , including natural and synthetic inputs for crop production nutrients, water, agro-chemicals and the consequences of nutrient and water management and pest control strategies; and.
Peer-reviewed published literature was obtained through searches of the Scopus academic database, through supplemental searches of published and grey literature in Google Scholar, and from a range of institutional sources including international agricultural research centers, U.
Additionally, using publication analysis John and Fielding we undertook a semi-quantitative assessment of the severity of crop x environment interactions and the amount of published research, using results from a systematic Scopus search of literature published since covering a wide range of categories of environmental constraints and environmental impacts. Good practices to manage constraints and reduce the impacts of these crop systems on the environment were also systematically assessed and summarized.
There is a large but variable body of knowledge in the peer-reviewed literature about the many biotic and abiotic constraints on crop yields, and an increasing amount known about how agriculture affects the environment.
We evaluated the relative importance of crop x environment interactions by assessing i the frequency with which an environmental constraint to crop production, or environmental impact from crop production, is mentioned in the peer-reviewed literature, and ii whether it is characterized in that literature as minor, moderate or severe. This accounting depends on the stock of literature, so we also assessed the amount of research number of published papers on these environmental topics for each crop in each region.
This helped us to identify apparent gaps in research on crop x environment interactions. Severity of environmental constraints reported. We summarized, for six general categories, the relative significance of various environmental constraints on crop production based on a comprehensive review of published literature and consultation with crop experts.
The categories include land availability, nutrient constraints, water constraints, biotic constraints, climate change, and post-harvest losses. No mentions of the environmental constraint in published literature or expert accounts on the crop. Consistently mentioned in published literature or expert accounts on the crop as a severe constraint.
Severity of environmental impacts reported. Precise estimates of crop-specific environmental impacts are rarely available. However based on the published literature and expert opinion some assessments of the relative severity of different environmental impacts could be made.
Thirteen major categories of environmental impact were identified from the detailed crop-based reviews of literature: land degradation, wild biodiversity loss, agro-biodiversity loss, water depletion, water pollution, soil nutrient depletion, soil pollution, pest resistance, methane CH 4 greenhouse gas GHG emissions, nitrous oxide N 2 O GHG emissions, air pollution largely relating to burning , storage chemical contamination, and post-harvest losses. No mentions of the environmental impact in published literature or expert accounts on the crop.
Consistently mentioned in published literature or expert accounts on the crop as a severe impact. Nevertheless, our categorization provides some indication of the relative importance of different environmental impacts both within crops and across different crops and systems as judged by the academic and expert communities to date. Depth of research on crop x environment impacts.
We conducted a comprehensive series of searches in the Scopus academic database for peer-reviewed articles published between and on the 13 categories of environmental impact for each crop and region. Appropriate sets of terms were constructed for the searches in consultation with crop experts and the search information compiled in spreadsheets.
Counts of peer-reviewed articles published on the various aspects of environmental interactions were then generated for the different crops and regions. These provide quantitative information on the degree to which environmental problems have received attention in recent scholarly debates. The number of environmental studies retrieved through our Scopus searches is highly uneven across crops, across environmental impacts, and across regions and continents.
The quality and depth of studies conducted also varies by crop and region. In an attempt to ensure only quality papers were included in the counts but still enable under-researched crops such as sweetpotato and cassava to be well represented , we eliminated all papers published before that Scopus reported had been cited fewer than two times. We also report papers cited only 2—4 times separately from more extensively cited papers with 5 or more citations since their publication.
For all food crops, farming decisions including the choice of crop or variety to plant, the types and amounts of inputs and their management are directly shaped by the availability and quality of cropland. In areas where land suitable for crop production remains relatively abundant — such as in much of Sub-Saharan Africa — the dominant response to land constraints continues to be conversion of forests, grasslands and other non-agricultural land to crops.
In South Asia, where land is now relatively scarce, farmers have primarily responded to land constraints through a process of intensification, involving multiple cropping during the year, typically facilitated by the adoption of irrigation, mechanization, organic and synthetic fertilizers, and pesticides.
In both cases — whether expanding agricultural production onto new land, or intensifying agricultural production on existing cropland — cropping decisions have direct and often significant impacts on land cover, soil structure and soil nutrients, as well as implications for on-farm and off-farm biodiversity Stevenson et al.
Land degradation and erosion : Land clearing exposes land to physical and chemical degradation, as well as contributing to air pollution. Over-cultivation and tillage of degraded and marginal lands damages soil structure, drives soil loss through erosion processes and reduces water retention capacity e. Loss of vegetative cover also worsens wind and water erosion on sloping uplands Bai et al.
Loss of wild biodiversity, both off-farm and on-farm : Cropland expansion, cropping intensification and repeated plantings can negatively affect wild biodiversity directly e. Loss of food crop genetic diversity: Shifts to more-intensive farming systems often reduce the number of crop species in agro-ecosystems e.
Replacement of multiple locally-adapted and genetically diverse crop landraces or varieties with a smaller number of modern varieties also reduces local and regional agro-biodiversity; in some cases increasing vulnerability to drought, pest infestations and other abiotic or biotic threats Altieri and Nicholls ; Snapp et al.
CO 2 emissions arise primarily from land conversion releasing C stored in forests , soil tillage releasing soil C and burning of fields and crop residues which releases both GHGs and particulate air pollution. Other major GHG sources are more crop- or system-specific: CH 4 emissions are primarily associated with flooded rice fields, and N 2 O emissions arise from N fertilizer application Reay et al.
The environmental and productivity-related impacts of land-use decisions are not only direct, but also systemic and cyclical in nature. For example, in addition to the intrinsic lost value of wild biodiversity, impacts stemming from land-use decisions may also inhibit provision of valuable ecosystem services such as pollination and pest control, with implications for future crop production Bommarco et al.
Similarly, climate change, though far less controllable by individual farmers, has impacts on both the global environment and on future local crop production in some specific regions Burke et al. Consequently, interventions directed at minimizing or eliminating the environmental impacts of cropping pre-production can have positive implications throughout current and future crop production cycles and in locations far from their origin.
Once crops have been selected and planted, various environmental factors including inadequate access to and use of soil nutrients, water shortages and drought, and direct damage from pests, weeds and diseases can substantially compromise production in both Sub-Saharan Africa and South Asia. At the same time, common responses to these production constraints such as applying chemical fertilizers, water extraction and irrigation, and applying pesticides and herbicides often themselves pose significant environmental risks and costs for crops, wildlife and human populations.
Effects may be especially severe when food crops are integrated into intensive repeated sequences and rotations with inadequate nutrient management, as is common in South Asia Timsina et al. Soil and water contamination : Excessive applications of synthetic nutrients can accumulate in and acidify soils, and runoff nutrients may accumulate in rivers and lakes and leach into groundwater Fageria Overuse of synthetic N is also a major source of global GHG emissions associated with fertilizer manufacture and use Reay et al.
Meanwhile overuse or improper use of pesticides and other agrochemicals in intensifying systems may threaten human health via poisoning and further contaminate soil and water, in addition to being an inefficient use of scarce farm resources Oluwole and Cheke ; Gupta Water depletion : Drought and water shortages represent significant constraints to yields and reduce viable cropping areas de Fraiture et al.
Efficient irrigation technologies can address water constraints to a degree, but the shortage and depletion of surface water especially in Sub-Saharan Africa where irrigation is poorly developed and groundwater resources mainly in South Asia where more irrigation systems already exist are growing problems Ali et al. Outbreaks, pest resistance, and new pests and diseases : Pests and diseases are frequent constraints and can be sufficiently devastating for some crops that they severely restrict cropping, as is the case with viral diseases of cassava in parts of East Africa Legg et al.
Application of pesticides and shifts towards pest- and disease-resistant crop varieties have gone hand-in-hand with the emergence of resistance in some pests, sometimes resulting in devastating outbreaks Oerke In other cases, efforts to address crop production constraints have inadvertently introduced new pest and disease problems — for example, the development and use of early-maturing varieties of sorghum and millet to overcome drought constraints has exposed grains to fungi and molds that now devastate harvests in some regions Haussmann et al.
As with pre-production decisions, the environmental and productivity-related impacts of crop management and input-use practices are both direct and systemic. For example, while synthetic N will often increase crop production, particularly in the many nutrient-depleted farms of Sub-Saharan Africa, the efficiency with which crops are able to convert synthetic N fertilizers to increased production hinges upon the availability of micronutrients and water often environmentally determined.
In the absence of these other inputs, the addition of large amounts of synthetic N will not be cost-effective for farmers, and may further exacerbate other environmental constraints such as soil acidification or contamination of water supplies with implications for current and future farm production and livelihoods.
Burning harms local air quality and contributes to respiratory ailments, as well as depleting soil organic C that could otherwise be used to stabilize soil structure, maintain soil fertility and raise the water-holding capacity of soils. Cereal crops such as maize also suffer significant losses in traditional storage from various pests and diseases Tefera , while inadequate harvest, storage and processing methods are major problems leading to high rates of post-harvest spoilage among root and tuber crops such as cassava and sweetpotato Lebot This lost production equates to not only wasted effort by farmers, but also wasted land clearing in extensive cropping systems and wasted agro-chemical application in more intensive systems for the production of food that will never be eaten.
In other words, post-harvest losses of crops carry the burden of all resources consumed in producing the harvest that is lost. Reducing post-harvest losses from poor processing or storage pests thus both increases food availability and reduces the per-unit weight or per-unit area environmental impact of a given crop harvest.
The following sections summarize the current status of published findings on crop x environment interactions by crop and by region. In both the dryland upland rice systems predominant in Sub-Saharan Africa and the irrigated rice systems of South Asia, the single most significant environmental constraint to rice production is water Fig.
Other common rice system constraints include inadequate soil nutrients, weeds in non-flooded systems , insects, rodents and assorted other pests Waddington et al.
Especially in South Asia, agricultural intensification involving the adoption of modern irrigation, fertilizers, improved seeds, and pesticides has contributed to dramatic gains in rice yields since the s Dawe et al. Many of these issues are especially acute for high-yield intensive irrigated winter season rice, which has become very important in parts of South Asia in recent decades Ali et al.
An additional environmental impact unique to flooded rice systems is an increase in insect-borne disease: flooded rice fields have been associated with an increase in malaria transmission among farmers, workers, and communities adjacent to flooded rice-producing areas in both Africa and Asia Larson et al. Most smallholder rice production in Sub-Saharan Africa is rainfed, low-input and low-yield upland rice.
The overall rice area remains relatively modest in Africa, though recent growth trends have been dramatic: the rice area harvested more than doubled between and , from 4. Some of this expansion is due to intensification made possible by irrigation and the introduction of Asian sativa varieties into lowland and wetland areas of Sub-Saharan Africa this has led to shifts from one to two crops per year, resulting in double-counting of some areas planted to rice Larson et al.
But for most smallholders, rainfed rice-fallow systems producing one crop per year remain common Dawe et al. Major environmental constraints in the region Fig. The key environmental threats from extensive low-productivity rice in Sub-Saharan Africa take the form of degradation of fragile and erosion-prone uplands Bai et al.
Although intensification also entails impacts such as chemical runoff and GHG emissions, such impacts have received little empirical attention in the published scholarship to date. Overall research on environmental impacts of rice is limited in Sub-Saharan Africa Fig.
No estimates of impacts such as land conversion or biodiversity loss attributable to upland rice are available, though some research is underway Phalan et al.
Moreover an expanding body of research surrounding the successes and failings of new NERICA varieties open-pollinated improved varieties of upland rice is beginning to identify upland rice constraints and impacts with greater detail see e. Research on environmental impacts in new irrigation-based rice systems in Sub-Saharan Africa lags behind research on production, and as there is very limited local information, current reviews of Sub-Saharan Africa rice environmental impacts largely draw on the Asian experience with rice intensification Larson et al.
Site-specific and somewhat more contested studies on improved soil and water management in Sub-Saharan Africa such as the System of Rice Intensification SRI , which was originally developed in Madagascar see Dobermann ; Uphoff et al.
Crop Storage is an essential and unavoidable part of the crop production process. PAMI developed a testing strategy to evaluate and compare the performance of several different air distribution systems designed for hopper bottom bins. Those results are available in evaluation reports , , and along with a handy frequently asked questions for natural air drying PAMI Notes GD PAMI constructed a one-of-a kind small-scale test setup to study process variables like grain temperature and relative humidity, ambient air temperature and relative humidity, airflow rate, bin weight, and grain moisture content during drying. Results from the small-scale test setup were verified in a bushel bin on a hopper bottom.

Drying is the process that reduces grain moisture content to a safe level for storage. Milling is a crucial step in post-production of rice. A rice milling system can be a simple one-or two-step process, or a multi-stage process. Go to selected references. A project of. Where is rice grown?
Crop Production - Harvesting & Storage
Seeds naturally have a place in almost any endeavor having to do with agricultural development. Seeds of most food plants are small and, as such, are more easily transported and can be shipped longer distances than vegetative cuttings. For the farmer, seeds represent the promise of a continued supply of food. For instance, distributing improperly stored seeds that germinate poorly could expose farmers to risk of crop failure.

Storage is an important marketing function, which involves holding and preserving goods from the time they are produced until they are needed for consumption. Underground storage structures are dugout structures similar to a well with sides plastered with cowdung. They may also be lined with stones or sand and cement. They may be circular or rectangular in shape. The capacity varies with the size of the structure. Foodgrains in a ground surface structure can be stored in two ways - bag storage or bulk storage.

While fulfilling the food demand of an increasing population remains a major global concern, more than one-third of food is lost or wasted in postharvest operations. Cereal grains are the basis of staple food in most of the developing nations, and account for the maximum postharvest losses on a calorific basis among all agricultural commodities. This paper provides a comprehensive literature review of the grain postharvest losses in developing countries, the status and causes of storage losses and discusses the technological interventions to reduce these losses. The basics of hermetic storage, various technology options, and their effectiveness on several crops in different localities are discussed in detail. Meeting the food demand of a rapidly increasing global population is emerging as a big challenge to mankind. The population is expected to grow to 9. Most of this population rise is expected to be attributed to developing countries, several of which are already facing issues of hunger and food insecurity. Increasing urbanization, climate change and land use for non-food crop production, intensify these concerns of increasing food demands. In the last few decades, most of the countries have focused on improving their agricultural production, land use, and population control as their policies to cope with this increasing food demand. Approximately one-third of the food produced about 1.

Vegetable farming , growing of vegetable crops, primarily for use as human food. The term vegetable in its broadest sense refers to any kind of plant life or plant product; in the narrower sense, as used in this article, however, it refers to the fresh, edible portion of a herbaceous plant consumed in either raw or cooked form. The edible portion may be a root, such as rutabaga, beet , carrot , and sweet potato ; a tuber or storage stem, such as potato and taro; the stem, as in asparagus and kohlrabi; a bud, such as brussels sprouts ; a bulb, such as onion and garlic ; a petiole or leafstalk, such as celery and rhubarb ; a leaf, such as cabbage , lettuce , parsley , spinach , and chive ; an immature flower, such as cauliflower , broccoli , and artichoke ; a seed, such as pea and lima bean ; the immature fruit, such as eggplant , cucumber , and sweet corn maize ; or the mature fruit , such as tomato and pepper. The popular distinction between vegetable and fruit is difficult to uphold. In general, those plants or plant parts that are usually consumed with the main course of a meal are popularly regarded as vegetables, while those mainly used as desserts are considered fruits.
