Abstract
Foliar application of boron improves seed cotton yield and fiber traits. A field experiment was conducted to study the effects of foliar application of 37 grams of boron (B) per acre (91.4 g ha-1) on quality and quantity of cotton (Gossypium hirsutum L.). Ten varieties of cotton viz, VH-183, VH-206, VH-208, VH-209, VH-214, VH-224, VH-225, VH-255, VH-257 and CIM-496 were sown at Cotton Research Station, Vehari during 2006-07 using randomized complete block design with three replications in two sets. The foliar application of B resulted in improvement of seed cotton yield (48-124%), ginning outturn (7.2-10.2%), staple length (1.4-10.1%) and micronaire (7.4-32.8%). A significant genetic variability existed for all the traits studied in cotton. The cotton varieties VH-183 and VH-206 were found to be the most promising varieties which responded well to B foliar application compared to other varieties. The results suggested that foliar application of B can be helpful in improvement of cotton yield and other plant and fiber traits
