Abstract

Field experiment was conducted at Agronomy farm B.A. College of Agriculture, Anand during Kharif season of the year 2004–05. The main objective of the study was to find out the effect of organic & inorganic fertilizer on seed yield of sweet corn (Zea mays L.). The experiment was studied with split plot design having two levels of Biofertilizer, FYM and phosphorus as main plot treatments along with five levels of nitrogen as sub plot treatment. Application of organic matter had significantly increased height and all crop growth parameters and 5.75 per cent more grain yield with application of FYM@10 ha−1. Seed inoculation with Pseudomonas gave significant increase in growth and yield parameters and grain yield increased to the tune of 8.24 percent. Application of phosphorus significantly increased plant height at all crop growth stages and higher grain yield recorded by 6.74 per cent than central. Seed yield of sweet corn as well as growth and yield attributes were significantly increased due to varying lends of nitrogen. The higher grain yield (1633 kg ha−1) and strawer yield (5783 kg ha−1) was recorded with 120 and 160 kg N ha−1 respectively. The net realization of Rs. 30525 and 29255 ha−1 was recorded with 10 Tn FYM ha−1. Seed inoculation gave 31485 Rs. ha−1 and application of P2O5 at 0 and 50 kg. P2O5 ha−1 gave 6.70 per cent and 4.43 per cent higher grain and straw yield, respectively. The significant higher strawer yield were recorded with varying levels of Nitrogen, but highest net return was obtained with 120 kg nitrogen per hectare, The strawer yield were increased significantly with increasing levels of nitrogen from 0 to 160 kg per hectare.
