RESPONSE OF DIFFERENT LEVELS OF NITROGEN AND PHOSPHORUS ON PLANT POPULATION, QUALITY AND ECONOMICS YIELD OF POPCORN (ZEA MAYS VAR. EVERTA)Shalini Kumari, P. J. Marsonia and 1Pamu SwethaAbstract A field experiment was conducted during rabi season of 2013-14 on calcareous soil under Saurashtra region. Response of different levels of nitrogen and phosphorus on plant population, quality and economics yields of popcorn (Zea mays var. everta). The experiment consisted of four levels of nitrogen (0, 90, 120, 150 kg N ha-1) and four levels of phosphorus (0, 45, 60, 75 Kg P2O5 ha-1) making sixteen treatment combinations tested in factorial randomized block design with three replications. Results indicated that application of 150 Kg N ha-1and 75 Kg P2O5 ha-1significantly increased the economics yield (Net return, BCR ratio and Gross return) whereas gives non significant effect on plant population and quality except crude protein content significantly increased by nitrogen (N3) 150 Kg N ha-1 of popcorn.
