Abstract

A field experiment was conducted at research farm of Cotton Section, Department of Plant Breeding and Genetics, Punjab Agricultural University, Ludhiana during kharif 2011 to work out the optimum plant density and fertilizers level for hirsutum cotton genotypes LH 2107, LH 2108, F 2164 and LH 2076. Among the hirsutum cotton genotypes, LH 2107 (2397.9 kg/ha) and LH 2108 (2244.1 kg/ha) were statistically at par with each other but proved significantly superior over F 2164 (1967.2 kg/ha) and LH 2076 (1905.4 kg/ha). Higher plant density at plant geometry of 67.5 x 60 cm (2195.0 kg/ha) was found to be significantly superior over lower plant density at plant geometry of 67.5 x 75 cm (2062.3 kg/ha). Application of 100% RDF (2220.0 kg/ha) was statistically at par with 125% RDF (2189.6 kg/ha) and both these treatments registered significantly higher seed cotton yield than 75% RDF (1976.3 kg/ha).
