1. Effect of Climatic Variability on Grain YieldsThere are three cycles in climate and weather that affect the north central part of the United States. They are (1) a long term cycle of global temperature changes; (2) an 18.5 year wet and dry cycle; and (3) the El Ni�o cycle. ... |
2. Site-Specific Management of Iron Deficiency in CornThe addition of FeS04mH20 in the seed row increases corn (Zea mays L.) yield in areas with Fe deficiency-induced chlorosis. Our objectives were to determine the correct application rate of FeS04.H20 for irrigated corn, identi9 the spatial distribution of Fe deficiency, and alleviate deficiency symptoms with targeted FeS04.H20 applications. Eleven site-years were selected for small-plot studies in western Kansas. At these fields, soil CaC03 content in chlorotic or problematic deficient areas of the... |
