Effect of Plant Geometry on the Economics of Sweet Corn (Zea mays) Varieties in Prayagraj Climatic Condition

An experiment was carried out during zaid season of 2020 at Crop Research Farm, NAI, SHUATS, Prayagraj (India) to the effect of plant geometry on the economics of sweet corn varieties in Prayagraj climatic condition. The experiment consisted of 9 treatments which includes three varieties of sweet corn (Sugar-75, Sweet Glory and Hybrid Indam-Suruchi) used with three different spacing (45 cm × 15 cm, 50 cm × 15 cm and 55 cm × 15 cm). The result revealed that, treatment 55 cm × 15 cm + Sugar -75 recorded maximum plant height (112.63 cm), no. of cobs/plant (1.17), cob yield (10.06 t/ha) and B:C ratio (2.07), whereas maximum stover yield was recorded with treatment 50 × 15 + Sugar -75 (2.85 t/ha) and net return (INR 90.56 × 10³/ha).
