Abstract:
Field experiment was conducted to study the influence of plant nutrient levels on the seed cotton yield and yield components in cotton during winter 2018–2019 and 2019-2020 at Tamil Nadu Agricultural University, Coimbatore, Tamil Nadu, India. The experiment was laid out in a Random Block Design (RBD) design with two different planting dates and six fertilizer treatments (150% RDF (N1), 125% RDF (N2), 100% RDF (N3),75% RDF (N4), 50% RDF (N5) and No fertilizer treatments (N6). The treatments were allotted randomly at each replication to reduce the experimental error. Observations on yield attributes and seed cotton yield were recorded. Yield components including number of sympodial branches/plant (10.77), number of flowers/plant (11), number of bolls/plant (12), single boll weight (10.17 g) and seed cotton yield (2247 kg/ha) were higher in the 150%RDF compared with other nutrient treatments. In the present study, 150%RDF gave high seed cotton yield and yield components of the cotton crop.
