Influence of Varied Plant Densities and Nitrogen Doses on Growth and Yield of Bt cotton (Gossypium hirsutum L.) Under High Density Planting System

A field experiment was conducted at College farm, of Agriculture, PJTSAU, Hyderabad during kharif, 2021-22 to study the growth and yield Bt cotton as influenced by varied plant densities nitrogen doses under high density planting system. The results revealed that among densities, height (102.8 cm) drymatter production (7396 kg ha-1) were higher with spacing 90 x 15 cm (74,074 plants on par 20 (55,555 ha-1). Whereas, sympodial branches plant-1 (21.0) leaf area (4143 cm2 plant-1) recorded 60 (18,518 Even though showed more number picked bolls (18.2), boll weight (5.10 g) but significantly seed (2176 which (2052 In case doses, application 180 N ha-1 parameters like (103.2 cm), (20.8), (6952 (3826 plant-1). 150 (2072 (12.9) (4.87 over other tested.
