Studies on Yield Attributes and Yield of Summer Maize (Zea mays L.) as affected by Rabi Legumes and Nitrogen

摘要

Field trials were conducted for two consecutive years, 2011-12 and 2012-13 to find out the nitrogen requirement of summer maize influenced by legumes during rabi in a legume-cereal sequence under irrigated conditions at Agricultural College Farm, Bapatla. Maize kernel yield was the highest when greengram was taken as previous crop. Application of nitrogen at 300 kg N ha~(-1) resulted in maximum kernel yield of maize. Total system productivity in terms of maize equivalent yields (MEY) and production efficiency (kg ha~(-1)day~(-1)) in legume-maize sequence was more in greengram -maize sequence.
