Abstract
A field experiment was conducted to study the effect of dose and time of imazethapyr on weed and yield in the summer season black gram. The predominant weed species in the experimental field were Eleusine indica, Amaranthus viridis, Commelina benghalensis, Alternanthera sessilis etc. The minimum weed population was observed with two-hand weeding at 20 and 40 DAS which was closely followed by imazethapyr @ 100 g a.i. ha-1 at 25 DAS and imazethapyr @ 75 g a.i. ha-1 at 15 DAS. Imazethapyr 100 g a.i. ha-1 at 25DAS recorded the pod length, number of seeds pod-1, test weight, harvest index, seed and stover yield. Application of imazethapyr @ 100 g a.i. ha-1 at 25 DAS gave a higher B:C ratio (1.03) as compared to two-hand weeding at 20 and 40 DAS.
通过田间试验研究了咪鲜胺的剂量和时间对夏季黑穗轴禾本科杂草和产量的影响。试验田中的主要杂草种类有荸荠、苋菜、贲门菜、泽兰等。在 20 和 40 DAS 期进行双手除草时，杂草数量最少，紧随其后的是在 25 DAS 期进行 100 g a.i. ha-1 吡嘧磺隆除草剂除草，以及在 15 DAS 期进行 75 g a.i. ha-1 吡嘧磺隆除草剂除草。在 25DAS 施用吡虫啉 100 g a.i. ha-1 时，豆荚长度、豆荚种子数、试验重量、收获指数、种子和秸秆产量均有所提高。与在 20 和 40 DAS 期进行双手除草相比，在 25 DAS 期施用吡虫啉 100 g a.i. ha-1 可获得更高的 B:C 比值（1.03）。
