Abstract:
An experimental study was done to understand the response of various intra-row spacings and phosphorus levels on yield and economics of sweet corn during summer season which was conducted at crop research farm, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj. At last the experiment concluded that maximum green cob yield (13.45 t/ha) and green fodder yield (22.47 t/ha) was reported with incorporation of 60 cm row to row with 15 cm plant to plant spacing along with application of phosphorus at 75 kg/ha. Whereas, harvest index (41.54%) was recorded higher in 60 cm row to row and 25 cm plant to plant spacing and at par values were noticed in 60 cm row to row with 15 cm plant to plant spacing and 60 cm row to row with 20 cm plant to plant spacing along with application of phosphorus at 75 kg/ha. However, gross returns (₹ 1,96,168.30/ha), net returns (₹ 1,34,553.30/ha) and B:C ratio (2.18) also denoted higher values in 60 cm row to row with 15 cm plant to plant spacing along with application of phosphorus at 75 kg/ha, respectively.
