Effect of intercropping on growth(plant height,number of leaves/tillers,dry matter composition) and yield attributes(number of cobs/plant, number of seed per cob, cob lenght,cob girth, grain weight per cob , test weight etc) of Maize when intercropped with Pigeon Pea?
Совмещенный посев является одним из основных способов повышения общего урожая и решения продовольственной проблемы. Однако, при выборе совмещенных культур необходимо уделять особое значение на биологические особенности обоих культур. Т.е, эти культуры не должниы отрицать друг друга. При совмещенном посеве кукурузы с бобовыми культурами бобовые растения повышает плодородия почвы и положительно влияет на рост и развития кукурузы
With rotational cultivation, intercropping and succession of crops of grains of pulses and maize the productivity of the land is greater, making the systems of cultivation of maize and legumes suitable, especially for smallholders. Rotation cultivation with pulses can increase the yield of corn by 25 percent. In conservation agriculture, corn and legumes increase the yield of grains by more than 33 percent than that of a single crop.
Intercultural maize-bean cultivation is a traditional practice among smallholder farmers in Latin America, especially in highlands where land is scarce. In Peru, almost all of the beans are grown, and in Ecuador about 80 percent of them are grown, along with maize. In areas of Central America where land is limited and rainfall is low, corn is often intercropped with beans.
In recent years, many smallholder farmers in South Africa have revived the traditional practice of growing legumes, including peas, along with corn. Often times, pulses are valued more as sources of food and income than for their contribution to soil fertility.
In Mexico, smallholder farmers have instituted a system of growing velvet beans in "off-season" corn fields, leading to significant increases in soil acidity, organic matter and nitrogen levels. This, in turn, contributes to a 25 percent increase in the yield of the corn crop.
In northern Ghana, when cowpea is grown, three to six weeks before the maize, it gives nutritious food while other crops have not yet ripened, and provides nitrogen to the soil with its residues.
