Abstract:

To investigate the water-deficit tolerance, 3 cotton genotypes (Bunny Bt, Pratima and Anjali.) were grown under normal irrigation and water-deficit conditions. Moisture is a key factor affecting growth and yield of Cotton in which stress is the most important factor limiting crop productivity due to adverse effect on fruit production, square/boll shedding and lint yield as well as fiber quality properties of Cotton. If water supply is limited during boll development it could result in significantly lower yields. In this study stress imposed with four watering treatments viz., 100, 75, 50 and 25% of field capacity at squaring stage given to understand effects of water deficit.We have noticed that 2.5 percent fiber length, fiber fineness and bundle strength decreases in inferior direction as reduction of soil moisture levels. Lint yield was generally reduced under water stress because of reduced boll production primarily due to the production of fewer flowers and bolls, but also because of increased rates of boll abortion when the stress is extreme during the reproductive growth stage. The number of bolls, lint per boll also affects while correlations among yield traits were higher in normal irrigation as compared with water stress moisture levels in all three varieties in which comparatively Bunny Bt performed better than Pratima and Anjali.
