Abstract: The experiment was conducted during the Rabi season 2019 at Prayagraj to study the Effect of row-spacing and weed management practices on yield and economics of Sweet corn (Zea mays L. saccharata). The experiment comprised of 2 factors and 10 treatments viz. Row spacings (40 cm and 50 cm) and weed management practices (Weedy check, Weed free check, Atrazine a.i @ 1.0 kg/ha PRE fb Hand weeding at 20 DAS, Tembotrione a.i @ 120 g/ha PoE and Atrazine a.i @ 1.0 kg/ha PRE fb Tembotrione a.i @ 120 g/ha PoE. Results revealed that application of 50 cm + Weed free check gave maximum no. of cobs/plant (1.28), no. of grains/cob (819.67). Whereas the maximum green cob yield (10.51 t/ha) was obtained with the application of 40 cm + Weed free check. Stover yield (21.33 t/ha) was maximum with the application of 40 cm + Atrazine a.i. @ 1.0 kg/ha PRE fb hand weeding at 20 DAS. Highest Weed control efficiency (98.63%) was observed with 40 cm + Weed free check followed by Atrazine a.i. @ 1.0 kg/ha PRE + Tembotrione a.i. @ 120 g/ha PoE (91.63%) and Atrazine a.i. @ 1.0 kg/ha PRE fb by Hand weeding at 20 DAS (85.12%).Whereas lowest Weed index was observed with 40 cm + Weed free check (0%), followed by 40 cm + Atrazine a.i. @ 1.0 kg/ha PRE followed by Hand weeding at 20 DAS (3.50%) and Atrazine a.i. @ 1.0 kg/ha PRE + Tembotrione a.i. @ 120 g/ha PoE (10.15%). Maximum gross returns (142906.5 Rs /ha) obtained with the application of 40 cm + Weed free check, maximum net returns (93211.34 Rs/ha) were obtained with the application of Atrazine a.i. @ 1.0 kg/ha followed by Hand weeding at 20 DAS and Maximum B: C ratio (1.90) was recorded with application of Atrazine a.i. @ 1.0 kg/ha followed by Hand weeding at 20 DAS.
