Effect of pre-plant incorporation herbicide mixtures on crop productivity and quality of soybean under crop-weed interference

Abstract

The BSP Unit, Department of Agronomy, JNKVV, Jabalpur (M.P.) performed a field experiment in Kharif 2019-20 in Randomised block design (RBD) with three replications was used to arrange the 11 herbicidal treatments that made up the study. The study revealed that highest seed yield (1811 kg ha-1) and the greatest harvest index (36.1%) were found under Diclosulam 0.9% + Pendimethalin 35% SE 22.5 + 875 g ha-1, respectively, demonstrating a significant superiority over other herbicide mixtures when applied as a PPI. The control plot had the lowest protein value (40%). Whereas, applying Diclosulam 0.9% + Pendimethalin 35% SE 22.5 + 875 g ha-1 (41.90%) and Diclosulam 0.9% + Pendimethalin 35% SE 45 + 1750 g ha-1 (41.70%) had the highest protein content, respectively. With the exception of hand weeding plots, no herbicide treatment outperforms hand weeding twice, making it noticeably better than all other treatments.
