Author(s): Banares Rashedi, Gautam Ghosh
Abstract: A field experiment was carried out during the Rabi season of 2015-16 at Crop Research Farm, Department of Agronomy, Allahabad School of Agriculture, SHIATS, Allahabad (U. P.) to evaluate the “Response of different sources of organic and inorganic nitrogen on growth and yield of sweet corn (Zea mays L. Saccharata). The experiment was laid out in Randomized Block Design (RBD) and replicated thrice. The treatments consisted of three level of Nitrogen 120:90:60 kg ha-1, and 120:60:30 kg N through Farm yard manure (FYM), and Poultry manure (PM). The result showed under treatment T4 (120 kg N through FYM), recorded maximum number of cob plant-1 (i.e.1.60) and cob girth (i.e.20.02 cm), however application of (120 kg N ha-1) significantly showed under treatment T1 green cob weight (i.e.359.37 g cob-1), while significantly the highest, cob length (i.e.26.33 cm), fresh cob yield (i.e.32733.33 kg ha-1), green fodder yield (i.e.35 t ha-1), and harvest index (i.e.48.32%) were observed in treatment T8 which consist of (90 kg N, and 30 kg N through PM). Further the highest gross return (Rs. 209500.00 ha-1), net return (Rs. 153324.24 ha-1), and benefit cost ratio (1: 3.73) were also recorded in treatment T8 respectively.
