Characterization of Yield and Phenology of Rainfed Cotton under High Plant Densities and Moisture Regimes
Abstract
Abstract
Spacing and moisture availability are considered as some of the critical management components in any cropping system to bring out a rewarding yield. This present study examines the effect of high plant densities and moisture regime on certain varieties of cotton in tropical monsoon-based southern Telangana agro-climatic zone. Six genotypes viz., are selected and studied their performance in high-density spacings viz., ADB- 39, H- 4492859, NDLH- 1938, Anjali, Suraj and WGLV- 48 were grown under three high density planting systems viz., 75×10 cm, 60×10 cm and 45×10 cm to study the relation between moisture stress and phenology and yield of cotton. Among the treatments in the study, WGCV-48 recorded the earliest square initiation (41.3 days), flower initiation (66.1 days) and boll bursting (92.6 days). And the combination of WGCV-48 and spacing of 45×10 cm recorded the maximum of lint yield (737 Kg Ha-1) and 100 seed index (8.7g).
