Yield Behaviour of Cotton (Gossypium hirsutum L.) Under Different Dates of Sowing in Spring Season

Abstract

A field experiment was conducted on cotton (Gossypium hirsutum L.) during spring season of 2008 in sandy loam soil at Crop Research Center of Sardar Vallabhbhai Patel University of Agriculture & Technology, Modipuram, Meerut. The experiment was aimed to evaluate the effect of date of sowing (15 February, 22 February, 29 February and 7 March) and genotypes (BH-7, LH-1995, BH-23 and Pusa S-2) on the performance of cotton yield. The experiment was designed as a split plot with 3 replication. The experiment consist of 16 treatment with date of sowing and genotype combinations. Among different. date of sowing, 29 February was found superior than the other date of sowing in term of growth, yield and yield attributes and quality parameters, where as genotype BH-7 produced the highest yield and yield attributes, which was higher than other genotypes. Objectives of the study were- 1. To asses the most suitable cotton genotype for spring season. 2. To evaluate the suitable time of sowing for spring season cotton crop. 3. To workout the maximum yield from different cotton genotype and date of sowing. It may be concluded on the basis of experiment finding that the expression of growth, yield and quality of cotton under the agro-climatic condition of western plain zone of U.P. can enhanced by 29 February sown crops with BH-7 genotype.
