“…Two hand weedings at 20 and 40 DAS recorded lower weed density of all types of weeds. This is in line with the findings of Yadav et al (2015), Teja et al (2016) and Susmitha et al (2019) because of complete removal of all types of weeds during early crop growth stages. Among the chemical weed management practices the treatment Pendimethalin 30% EC @ 1.0 kg a.i.…”

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.

“…Many legumes have been reported by a number of authors to extend the effects of IM, such as kharif black gram [5], green gram [6], lentil [7], soybean [8,9], and oilseed rap [10]. Chickpea (Cicer arietinum L., Leguminosae) is the second omnipresent grown legume after soybean worldwide [11,12].…”

Weeds are a serious obstacle to the production of chickpea. Imazethapyr (IM) herbicide is used to control weeds in most of the pulses, including chickpea. Mitotic abnormalities, chromosomal behavior, and protein content in chickpea (Cicer arietinum L.), due to IM treatment, were studied. The chickpea seeds (variety JG-11) were germinated in sterilized Petri dishes, 9 cm in diameter, on Whatman filter paper moistened with 10 ml of either Hoagland nutrient solution (control) or five concentrations of IM (0.5, 1, 2.5, 5, and 10 ppm). From the cytologic point of view, observations demonstrated that the mitotic frequency in root meristematic cells diminished, and that abnormality frequency increased parallel to the increase in concentrations of IM. The herbicide was highly mito-inhibitory and induced chromosomal irregularities, such as stickiness, lagging, scattering, and chromosome bridges. The endosperm and root-shoot axis' protein content decreased with increasing of the herbicide concentration in all the treatments. It can be argued that IM produces undesirable side effects during mitosis in chickpea's somatic cells and biochemical parameters.
