Abstract Cotton (Gossypium hirsutum L.) is of prime importance because of its quality fiber and edible oil production. Boron (B) is among essential micronutrients for plant growth; it aids in the transfer of sugars and nutrients from leaves to fruit that are involved directly or indirectly in many plant functions. Cotton growth, yield and quality are strongly affected with boron application. A two-year study was conducted to evaluate the impact of foliar applied B (0, 2, 4, 6, 8 and 10 g of B L−1 of water) on the performance of cotton cultivars (FH-113, MNH-786 and CIM-496). The results indicated that growth, yield and quality traits of cotton were significantly influenced by different levels of foliar applied boron as well as cultivars of cotton. Among cotton cultivars, the yield and quality parameters were superior in cultivar “FH-113.” Foliar application of boron at 6 g L−1 of water improved leaf area index and leaf area duration and eventually improved the number of bolls per plant, boll retention percentage, average boll weight, lint yield, ginning out turn, fiber length and uniformity ratio of cotton. Foliar application of B at 6 g per liter of water, showed promising results by improving growth and quality parameters and is recommend to enhance the economical yield production of cotton cultivar “FH-113” with improved quality.

叶面施硼提高棉花品种的产量，提高棉铃保留率

摘要 棉花 (Gossypium hirsutum L.) 因其优质的纤维和食用油产量而具有重要意义。硼 (B) 是植物生长必需的微量营养素之一；它有助于将糖分和营养物质从叶子转移到果实，直接或间接参与许多植物功能。棉花的生长、产量和质量受硼的影响很大。进行了一项为期两年的研究，以评估叶面喷施 B（0、2、4、6、8 和 10 克 BL-1 水）对棉花品种（FH-113、MNH-786 和CIM-496）。结果表明，不同叶面喷施硼水平和棉花品种对棉花的生长、产量和品质性状均有显着影响。在棉花品种中，品种“FH-113”的产量和品质参数均较好。” 叶面喷施 6 g L−1 水的硼提高了叶面积指数和叶面积持续时间，并最终提高了单株棉铃数、棉铃保留率、平均棉铃重、皮棉产量、轧花率、纤维长度和均匀度棉花的比例。每升水 6 克叶面喷施 B，通过改善生长和质量参数显示出有希望的结果，建议提高棉花品种“FH-113”的经济产量并改善质量。
