Abstract:

A field experiment was conducted during two consecutive kharif seasons of 2014 and 2015 to evaluate the effect of different levels of nitrogen (200, 250 and 300 kg ha-1) and phosphorus (40, 60, and 80 kg ha-1) on the growth and yield of maize. The growth parameters of maize viz., plant height, leaf area index and dry matter production were considerably influenced by nitrogen and phosphorus levels at 30, 90 DAS and at harvest in the first year and only by nitrogen levels at all the stages on dry matter production and on LAI at 90 DAS in the second year. Interaction was not significant except at 90 DAS on plant height and at harvest, on dry matter production in the first year. During both the years, the highest and lowest grain and stover yields were recorded with N level of 300 kg ha-1 and 200 kg ha-1 and with P level of 60 kg ha-1 and 40 kg ha-1 respectively. The combination of 250 kg N and 60 kg P2O5 ha-1 resulted in higher yield of maize during kharif season.
