The morphological and phenological performance of different cotton genotypes under different plant density
Article Main
Abstract
The field experiment conducted with different plant density and different Genotypes showed significant differences in their morphological characters and phenological characters. Among the genotypes, AKA-7 possessed higher plant height (116.4 cm), No. of sympodia (19.27 plant-1) and leaf area index (3.628) compared to other geno-types but leaf area (33.02 dm-2) and dry matter weight (103.21g/plant) were recorded higher with genotype Balwan. However, Normal plant density (100%) was registered higher plant height (102.6 cm), no of sympodia (17.33 plant-1), leaf area (27.02 dm2) and dry matter weight (58.13 g/plant) but higher leaf area index (3.430) was recorded with higher plant density (200%). Among the genotypes, AKH-081 was comparatively earlier in phenological characters i.e. first square (47.9 days), first flower (67.9 days), first boll burst (116.1 days), first picking (128.7 days) and final picking (178 days). However, Higher planting density (200%) was recorded earlier in first square (49.3 day), first flower (67.8 days), first boll burst (116.9 days), first picking (130.6 day) and final picking (179.7 days). On the basis of this experiment, genotype Balwan and normal planting density level (100%) recorded higher morphological development wherever phenological development recorded earlier with the each respective phenophase in the Gen-otype AKH-081 and highest planting density level (200%).
