Response of Spacing and Nitrogen on Yield and Economics of Kharif Sweetcorn (Zea mays L. saccharata)

A field experiment was conducted during Kharif 2022 at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (U.P). To study treatments consisting three levels Nitrogen such as, 80, 100 and 120 kg/ha with spacing as 75 x 10 cm2, 60 20 cm2 45 30 cm2. The soil experimental plot sandy loam in texture, nearly neutral reaction (pH 7.1), low organic carbon (0.28%), available N (225 kg/ha), P (19.50 kg/ha) K (92 kg/ha). There were 9 each being replicated thrice laid out Randomized Block Design. results revealed that treatment 8 (Nitrogen + 65x20 cm) recorded maximum number cobs/plant (2.33), higher seeds/row (41.33), row/cob (14.40), weight green cob (351.20 g), yield (4.15 t/ha), stover (4.59 harvest index (45.90 %), gross returns (1,48,950.00 INR/ha), net (1,04,914.00 INR/ha) benefit cost ratio (2.38).
