1. 2019-01-20 The integration of livestock on a smallholder farm is key to its productivity. Livestock play a unique role on the farm, transforming plant materials and other waste products into important sources of protein, either for consumption on the farm, or for sale beyond it. Pigs are one of the most...



  2. 2019-01-20 Given the proper facilities necessary to store seeds long-term, whereby low temperature and low humidity are kept stable over time, it is very possible to store most orthodox seeds for several years at a time in the tropics (Harrington, 1972). Unfortunately, implementation and maintenance of the...



  3. 2018-11-20 Natural farming techniques have been heavily promoted in ECHO’s Asia network. The aim of these techniques is to reduce reliance on chemical inputs by enriching soils with beneficial microorganisms. Soil microbes break down organic matter, releasing nutrients for uptake by crop roots. They also...



  4. 2018-11-20 Root-knot nematodes invade crop roots, form galls, and steal plant nutrients causing 125 billion dollars of crop loss worldwide (Ara and Hossain, 2011). Biological control methods such as compost, yard waste, and organic fertilizers can release nematicidal compounds as they decompose (McSorley,...



  5. 2018-11-20 INTERIOR: How does farming expand a spiritual leader’s understanding of self, faith and vocation? EXTERIOR: How does farming expand a spiritual leader’s understanding of creation, people and culture?



  6. 2018-11-20 Grain sorghum(Sorghum bicolor)and pearl millet (Pennisetum glaucum)are both globally important warm-season,annual cereal grain crops.Small-scale farmers who grow these grains can belimited by access to fertilizers and human labor. Agricultural low input systems use few commercial inputs,...



  7. 2017-11-01 Insect pests can result in substantial losses of stored seed. In West Africa, cowpea bruchids (Callasobruchus maculatus) caused up to 100 percent damage of cowpea seeds stored for a few months (Sallam 1999). Primary pests are those that, in larval stage, feed within intact kernels. Others, such...

  9. 2017-11-01 While availability of food calories has paralleled human population growth in Rwanda, the supply of highly nutritious foods -such as complete protein, fats, and micronutrients -remain insufficient in the Rwandan diet. Past research has shown the barriers to Rwandans raising chickens to be a lack...



  10. The 2:4 maize–double cowpea system consists of 4 rows of cowpea and 2 rows of maize, all planted on the same day. The second cowpea crop is planted after the first has been harvested (about 60 days after planting).1 The maize and cowpea are densely planted. The objective of this trial is to gain...



  11. 2017-11-01 A large percentage of the world's hungry people are primarily vegetarians, and even vegans, either due to religion or poverty. Although some might find that a sad fact, the reality is that a whole foods, plant-based diet can produce the world's healthiest people, as a National Geographic reporter...



  12. 2017-11-01 Can biochar replace perlite in seedling mix? Perlite is light weight, sterile, porous, increases drainage, improves aeration, and helps to keep soil unsaturated and un-compacted. Bio-Char is light-weight, sterile, porous, and holds water without getting saturated, giving it the potential to...



  13. 2017-11-01 By integrating legumes intoc ropping systems, small-scale farmers in low-resource settings can invest in the long-term health and resilience of their soils. Success or failure depends largely on choosing the right legume(s). Selection or screening trials are use ful experiments that direct...



  14. 2017-11-01 Green manures / covercrops (GMCCs) are widely recognized as having potential to help farmers improve crop yields and maintain high soil quality. Developed by the International Institute of Tropical Agriculture, 2-4-2 is an intercropping strategy in which two rows of maize are alternated with four...



  15. 2016-01-20 Moringa is known for its ability to grow in a wide range of soils. We hypothesized, however, that moringa leaf production can be increased by applying fertility inputs at the base of the trees. We wanted to know: Do moringa trees benefit from fertility inputs? If so, how many grams of nitrogen...



  16. 2016-11-20 The 2:4 maize–double cowpea system consists of a repeating sequence of 4 rows of cowpea alternated with 2 rows of maize. Maize and cowpea are planted on the same day. The second cowpea crop is planted after the first has been harvested (about 60 days after planting).1The objective of this trial...



  17. Plants contain oxalates for a few reasons. The first is that plants do not have an excretory system like animals, so oxalates allow plants the ability to bind up excess calcium (Webb 1999).Plants high in oxalates can have negative effects on the ability of animals to absorb calcium after eating...



  18. Salt buildup typically occurs in dry areas where evaporation exceeds precipitation. Over time, as water evaporates, the minerals left behind begin to accumulate. Plants need a certain amount of soluble salts, but when the salt content of soil water is greater than that of the water inside plant...



  19. After modifications to the ECHO Global Seed Bank storage unit, seed storage techniques already in use were assessed for effectiveness in achieving appropriate seed storing conditions within the renovated cooling and dehydrating system.Seed type influenced the effect of container on relative...





  20. Some tropical crops contain cyanogenic glycosides, toxic substances that release hydrocyanic acid (HCN; also referred to as cyanide) when cells are crushed. Consuming these plants without cooking them can cause cyanide poisoning, with varying effects depending on cyanide levels and how long a...
