Grain yield and N-Uptake by rabi maize (Zea mays L.) at varying planting densities and nitrogen levels


Author(s): K Revathi, M Sree Rekha, MK Sheshama and Girraj Sharma

Abstract: A field experiment was conducted during rabi season 2014-15 at Agricultural College Farm, Bapatla to study the “Growth and yield of rabi maize at varying planting densities and nitrogen levels”. The experiment was laid out in a split plot design and replicated thrice. The results revealed that planting density of M1 (1,00,000 plants ha-1) and S8 (300 kg N ha-1+ 0.5% ZnSO4 as foliar spray at tasseling) which was on a par with M1 (1,00,000 plants ha-1) and S4 (300 kg N ha-1) recorded highest yield attributes and yield. Foliar application of ZnSO4 with nitrogen at tasseling influence the yield attributes, grain & straw yield significantly. The interaction between planting densities and nitrogen levels was found to be non significant.
