Residual phosphorus and management strategy for grain sorghum on a vertisol

Direct and residual phosphorus effects on grain yieldphosphorus uptake relationships in upland rice on an ultisol in West Africa

Phosphorus (P) deficiency is a major constraint to crop production on highly weathered, lowactivity clay soils in the humid zone of West Africa. Past research suggested a linear relationship between grain yield and P uptake over a range of fertilizer P applied to upland rice cultivars. However, there is lack of information on how these relationships are affected by the long-term fertilizer ...

tillage and phosphorus management effects on stratification of phosphorus in a grain corn production system

introduction phosphorus (p) is an essential element in crop nutrition, which can be growth limiting or an environmental contaminant, if present in excess. on the other hand, tillage practices have a direct effect on behavior and availability of soil p. since, application of different tillage methods lead to different patterns of soil phosphorus distribution, hence p fertilizer needs and p avail...

Analysis of grain yield stability and assessment of genotype × environment interaction for grain sorghum (Sorghum bicolor L. Moench) genotypes

The interaction of genotype × environment creates complications in yield prediction and is a challenge for agronomy and plant breeding programs. To evaluate grain yield stability and genotype × environment interaction for 18 local and exotic grain sorghum cultivars, lines, and hybrids, a field experiment was conducted using randomized complete block design with three replications in four region...

Effects of substituting sorghum grain for barley on milk yield and composition of dairy cows

Assessing China's Potential Surge on Demand for Grain Sorghum

China is one of the world's fastest growing economies showing an impressive growth on consumption of animal protein which has resulted on a rapidly increasing derived demand for feed grains. Corn is the key feed crop for China, however, the government policies have boosted domestic corn prices above international levels. Some important facts signal that China is becoming a large market of feed ...
