Integrated weed management in green gram [Vigna radiata (L.) Wilczek]
Keywords:
Diclosulam, Hand weeding, Imazethapyr imazamox, Stale seed bed, Weed control efficiencyAbstract
A field experiment was conducted from December 2020 to March 2021 at the Department of Agronomy, College of Horticulture, Vellanikkara, to develop an integrated weed management strategy for green gram. Hand weeding at 20 DAS and 40 DAS recorded the lowest weed dry matter production and the highest weed control efficiency. All the treatments where pre-emergence herbicide application was integrated with hand weeding were highly effective in reducing the weed dry matter production. Weed control efficiency was the highest (97 per cent) in imazethapyr + imazamox followed by (fb) hand weeding, and diclosulam fb hand weeding. Plant height, number of branches/plant, number of pods/plant and number of seeds/pod in green gram were significantly improved with weed management practices as compared with unweeded control. Weed control efficiency, biometric parameters and grain and haulm yields of green gram were significantly lower with the stale seed bed technique. Grain and haulm yields were the highest in hand weeding, which was statistically at par with all the weed management practices where herbicides were integrated with hand weeding. The highest B: C ratio was observed in imazethapyr + imazamox fb hand weeding (1.28), followed by diclosulam fb hand weeding (1.27).References
