Abstract
An investigation was carried out at Narendra Deva University of Agriculture & Technology, Faizabad (U.P.) during Kharif season of 2013 to find out the effect of different levels of humic acid and salicylic acid on yield contributing parameters and yield of cowpea. The design of the experiment was Randomized Block Design and comprises of six treatments replicated thrice. The maximum pod per plant was recorded with T5 (Foliar spray of humic acid (26 ml/liter water) and 0.2% salicylic acid at 35, 55 and 65 DAS) while minimum number of pods per plant recorded in T2 (Foliar spray of humic acid (26 ml/liter water) at 25 DAS and 0.2% salicylic acid 55 DAS). Maximum pod length (75.92 cm), Maximum number of seed per pod (13.67) and 100 seed weight (13.29 g) was recorded in T5, followed by T4. The maximum seed yield per plant of 13.10 g and harvest index (42.28 %) was reported with the application of humic acid @ (26 ml/liter water) and 0.2% salicylic acid at 35, 55 and 65 DAS.不同水平的腐植酸和水杨酸对豇豆产量参数和产量的影响
2013 年 Kharif 季节，在法扎巴德（宾夕法尼亚州）Narendra Deva 农业与技术大学进行了一项调查，以了解不同水平的腐植酸和水杨酸对豇豆产量贡献参数和产量的影响。试验设计为随机区组设计，包括六个处理，重复三次。T5（在 35、55 和 65 DAS 期叶面喷施腐植酸（26 毫升/升水）和 0.2%的水杨酸）的单株豆荚数最多，而 T2（在 25 DAS 期叶面喷施腐植酸（26 毫升/升水）和 55 DAS 期叶面喷施 0.2%的水杨酸）的单株豆荚数最少。T5 的豆荚长度最大（75.92 厘米），每荚种子数最多（13.67 粒），种子重量最大（13.29 克），其次是 T4。在 35、55 和 65 DAS 施用腐植酸 @（26 毫升/升水）和 0.2% 水杨酸时，每株种子产量最高，为 13.10 克，收获指数最高，为 42.28%。
