A field experiment involving cotton (Gossypium hirsutum L.) was conducted for two years to investigate the effects of deficit irrigation on seed cotton yield, fiber quality, and water productivity in Turkey. The main plots featured various drip line spacing, and the sub-plots included four irrigation levels based on class A pan evaporation in Turkey. Crop evapotranspirations were found to range from 585 to 1028 mm and from 601 to 1074 mm in consecutive years. Seed cotton yields ranged from 239.0 to 616.3 kg ha-1, and the analysis of variance showed the presence of the statistically significant (p ≤ 0.01) effects of irrigation levels on crop yield. The drip line spacing was effective for the yield only in the second year (p ≤ 0.05). Employed limited irrigation affected ginning outturn significantly (p ≤ 0.01) in both years. The results indicated that reduction in irrigation water did not have a significant effect on most fiber quality criteria. On the contrary, significant differences were observed for the leaf area index (LAI) traits of the treatments, and these reached the highest value approximately 100-110 days after planting. However, water productivity (WP) and irrigation water productivity (IWP) did not show significant differences among the limitations of irrigation water levels. [ABSTRACT FROM AUTHOR] |
