Effect of Weed Management Practices and Bio- fertilizers with and without FYM on Weed Flora, Growth and Yield of Blackgram (Vigna mungo L.)

Abstract

A field experiment was conducted in farmer’s field at Narasipuram block, Coimbatore, Tamil Nadu during summer season, 2021-22, to study the influence of weed management practices and bio-fertilizers with and without FYM on weed flora, growth and yield of blackgram. The experiment was laid out in split plot design with three replications. Treatments consisted of four weed management practices as main plots, viz., M1- PE Pendimethalin 30% EC 1 kg ha-1 sprayed at 3 DAS, M2 - EPoE imazethapyr 10% SL 50 g ha-1, M3 – EPoE Quizalofop-p-ethyl 5% EC 50 g ha-1applied at 10 DAS and M4 - two hand weeding (15 and 30 DAS) and four different treatments of bio-fertilizers with and without FYM viz., S1 – Rhizobium + Phosphobacteria, S2 – Rhizobium + Phosphobacteria + AM fungi, S3 – S1 + FYM, S4 – S2 + FYM and S5 - control. The results revealed that interaction effect of pendimethalin 1 kg ha-1 (M4) and Rhizobium + Phosphobacteria + AM fungi with FYM (S4) recorded maximum growth and yield parameters viz., plant height, dry matter production, number of pods plant-1, seeds pods-1, pod length and 100 grain weight. Moreover, produce higher grain and haulm yield compared over rest of treatments.
