Response of Black Gram (Vigna Mungo L.) to Integrated Weed Management and Its Effect on Weed Dynamics

Abstract

A field experiment was conducted during the rabi season of 2020-21 in Kurnool district of Andhra Pradesh in a farmers's field to access the efficacy of integrated weed management on weed dynamics in blackgram (Vigna mungo L.). Data on weed dynamics revealed that significantly lesser weed density, weed dry weight and high weed control efficiency were obtained with application of Pendimethalin 30% EC @ 1.0 kg a.i. ha -1 as PE + Imazethapyr 10% SL @ 50 g a.i. ha -1 at 25 DAS as post-emergence. The higher values of all the weed dynamics except weed control efficiency were registered with the treatment Weedy check. Growth and yield parameters of blackgram viz., plant height, number of branches plant -1 , number of leaves plant -1 , LAI, CGR, RGR, number of pods plant -1 , length of pods, number of seeds pod -1 , test weight, grain yield, stover yield and harvest index were significantly higher with the application of Pendimethalin 30% EC @ 1.0 kg a.i. ha -1 as PE + Imazethapyr 10% SL @ 50 g a.i. ha -1 at 25 DAS as post-emergence. The highest net returns and benefit-cost ratio were also recorded with the application of Pendimethalin 30% EC @ 1.0 kg a.i. ha -1 as PE + Imazethapyr 10% SL @ 50 g a.i. ha -1 at 25 DAS as postemergence.

Root Parameters of Blackgram (Vigna Mungo L.) Improved by Seed Pelleting With Nutrients and Foliar Spray of Nutrients and Plant Growth Regulator

“…Among various pulses blackgram (Vigna mungo L.) has its own importance. Blackgram (Urd bean) is the fourth most important pulse crop in India after chickpea, pigeon pea and green gram (Reddy et al, 2022). Black gram supplies a major share of protein requirement of vegetarian population of the country (Sengar et al, 2020).…”
