Evaluating different interrow distance between corn and soybean for optimum growth, production and nutritive value of intercropped forages
Background Maize fodder is being used as staple feed for livestock but it lacks protein and essential amino acids; lysine and tryptophan. Intercropping maize with leguminous soybean crop is promising technique under limited land resources of South Korea but it can only give considerable advantages when adequate distance is provided between corn and soybean rows. Main aim of present study was to...
متن کاملinvestigation of multiple competition of weeds at different corn (zea mays l.) densities
in order to study the weed damage and to determinate the influence of weed species and multiple weed species competition in corn (zea mays l.), a field experiment was conducted based on interval mapping at the agronomy research field of ferdowsi university of mashhad during 2009-2010. treatments consisted of four density level of crop (5, 6, 7 and 9 plant.m-2) and four type of weed management (...
متن کاملInfluence of Corn Sowing Density and Gliricidia Intercropping
There is interest in the identification of the best seeding density for new corn hybrids and on reduced use of herbicides for weed control. The objective of this study was to evaluate the effects of seeding density (30, 50, 70, and 90 thousand plants ha) and weed control on green ear yield and grain yield in corn cultivar AG 1051. A completely randomized block design was adopted with split-plot...
متن کاملProblem Weeds in Hay and Forages for Livestock
Although they may only make up a small portion of the cases presented to veterinarians, poisoning cases often require special effort. When food animals are exposed to poisonous weeds, a devastating case with large morbidity and mortality may ensue. The concern is for the herd and economics as much as treatment of the individual animal. In addition, producers and veterinarians must address food ...
متن کاملIntercropping corn with soybean, lupin and forages: yield component responses
Intercropping systems influence yield variables of the component crops, such as harvest index, hundred seed weight, number of reproductive organs and number of seeds, within each reproductive unit. Two experiments were carried out at each of two sites during 1993 and 1994. The first experiment investigated the effects of seeding soybean or lupin alone or in combination with one of three forages...
