A field experiment was conducted during Kharif 2022 at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (U.P) on the topic “Influence of Spacing and Nitrogen on growth and yield of Kharif Sweet corn (Zea mays L. saccharatam)”, to study treatments consisting of three levels of Nitrogen viz. 80, 100 and 120 kg/ha with spacing such as 75x10 cm2, 60x20 cm2 and 45x30 cm2. The soil of experimental plot was sandy loam in texture, nearly neutral in soil reaction (pH 7.1), low in organic carbon (0.28 %), available N (225 kg/ha), available P (19.50 kg/ha) and available K (92 kg/ha). There were 9 treatments each being replicated thrice and laid out in Randomized Block Design. The results revealed that treatment 8 (Nitrogen 120 kg/ha + 65x20 cm2) was recorded higher plant height (190.82 cm), higher plant dry weight (81.49 g), maximum number of cobs/plant (2.33), higher seeds/row (41.33), maximum row/cob (14.40), weight of green cob (351.20 g), higher green cob yield (4.15 t/ha), higher stover yield (4.59 t/ha), harvest index (45.90%), gross returns (1,48,950.00 INR/ha), net returns (1,04,914.00 INR/ha) and benefit cost ratio (2.38).
