摘要

Proper pollination and bunch management are vital to improving date palm productivity and fruit quality. The present study was conducted on 6‑year-old tissue culture derived date palm cv. ‘ADP-1’ in hot-arid Indian conditions. The objective was to achieve higher yield and superior fruit quality by standardizing the right time for pollination, optimum crop load and bunch cover. Our findings revealed that pollination had no discernible negative effects on yield or yield attributing traits including fruit weight and pulp weight until 36 h following spathe splitting. However, it was found that the best time to pollinate was between 12–36 h following spathe splitting. The best combination for achieving a high marketable yield of better-quality fruits (total soluble solids, sugar, etc.) was 12 bunches per tree plus 25% strand thinning. Fruit quality attributes were also affected by bunch covering; nonwoven bagging resulted in the largest percentage (28.6%) of pind stage fruits and increased overall fruit yield by 35.8% as compared to the uncovered control.
