Influence of Plant Density vis-à-vis Architecture on Growth Parameters Bt Cotton (Gossypium hirsutum L.)

A field experiment entitled “Influence of plant density vis-à-vis architecture on Bt cotton (Gossypium hirsutum L.) yield and quality parameters” was carried out sandy loam soil at College farm, Agriculture, PJTSAU, Rajendranagar, Hyderabad during 2021-22. The laid in split plot design with three replications. Results revealed that densities, plants sown under planting 90 x 20 cm (55,555 ha-1) recorded highest growth contributing characters such as height, dry matter production, first fruiting node length, internode length height ratio. Planting 30 (37,037 has significantly higher number sympodial branches no nodes per 2021 2022 pooled mean. Length from 5 to 15, 15 terminal, all branches, distance main stem boll position diameter, days initiation square initiation, 50% flowering, formation, bursting stage were found be spaced 60 (18,518 two years study Interaction significant drymatter production 120 DAS treatment combination semi open type (Sadanand) Number monopodial showed non-significant results.
