Morphological lodge of desi cotton (Gossypium arboreum L.) genotypes and stage-manage by planting log under dry tropical prospect

Planting log is the most considerable factor which directly manipulates the plant traits under naturally prevailing environment. The aim of the trial was to ensure the influence of planting hiatus on the morphological cabin of Desi cotton (Gossypium arboreum L.) varieties under dry tropical coast. The research was carried out during 2016 on three desi cotton genotypes C1 (FDH-512), C2 (FDH-502), C3 (FDH-170) under three-fortnightsowing regimes (S1 = 15. March, S2 = 1. April and S3 = 15. April) at agronomy research area in the Lasbela University of Agriculture, Water and Marine Science, Uthal, Lasbela, Pakistan. Momentous results were originated for different morphological traits according to the arid environments. Significant results were observed for traits i.e.; number of monopodial branches, number of sympodial branches, number of capsule per plant, number of seeds per capsule, number of locules per capsule, number of seeds per locules, weight of seed per capsule, seed colour, seed yield per plant, lint percentage, root shoot ratio (%), root depth (cm) for various sowing dates and desi cotton varieties. Results of the traits like i.e. the number of locules and per capsule, a number of seeds per locules was yielded completely non-significant outcomes both for the diverse sowing period and desi cotton genotypes. The interaction between the both factors was found to be non-significant in all traits. The correlation amongst cotton individual characteristics was observed, it was found that capsules per plant and lint percentage, monopodial branches per plant, root shoot ratio, root depth, seed weight per capsule and seed yield per plant were significantly and positively correlated. The seed yield and lint percentage was also significantly correlated, which showed that selection may be positive responsive in sense of lint percentage, monopodial branches, seed yield per plant, capsules per plant and seed weight per capsule to get a superior yield of cotton. Under the existing dry climatic condition, it was found that the finest planting window of 15. April for the desi cotton FDH-170 is most suitable for its cultivation.
