Impact of genotypes and high density planting on yield and yield attributes and quality parameter in hirsutum cotton

Abstract

The experiment was laid out in a Randomised block design with three replications. There were twelve treatment combinations. Four levels of plant geometry viz. 45×10 cm, 60×10 cm, 75×10 cm and 60×15 cm and three hirsutum genotypes of cotton namely AKH081, NH615 and Suraj were applied. The gross plot size was 2.7 ×3 m2. The quality parameters like 2.5% staple length fiber strenght, microniar value, fiber fineness and uniformity ratio were not influenced significantly by plant geometry and genotypes. Plant geometry 45×10 cm recorded significantly higher seed cotton yield (kg/ha). Cotton genotype AKH 081 can be sown at plant spacing 45×10 cm recorded more seed cotton yield (2428.89 kg ha-1).
