“…The data were suitably illustrated with graphs and figures at appropriate place. [8] and Dewangan et al [9] reported similar findings in terms of weed flora in chickpea field. Among different levels of crop residue retention, it was observed that the all levels of crop residue retention had significantly lower total weed density as compared to no/nil crop residue retention (Table 1).…”

A field experiment was conducted at ICAR- Indian Institute of Soil Science (IISS), Bhopal (Madhya Pradesh) to evaluate the impact of different levels of crop residue retention and herbicidal weed control measures on weed dynamics, crop growth and yield characteristics of chickpea crop under conservation agriculture. Data were recorded on weed study, crop growth and yield characters of chickpea. Results indicate that pre-emergence herbicide application treatments (H1 and H2) were found to be effective in reducing weed density at 30 DAS (63.56%) as compared to post emergence treatments which were applied after recording observations on weed density at 30 DAS. It has been observed that post emergence application of imazethapyr @ 25 g a.i. ha-1 was found to restrict crop growth for a period of 10-15 days as compared to pre-emergence treatments. The results on crop growth and yield parameters revealed that higher residue retention level treatment (90% crop residue retention) recorded significantly higher plant height (54.81cm), dry matter plant-1 (18.39 g plant-1), number of pods plant-1 (36.46), seeds plant-1 (47.11), seed yield (1202 kg ha-1) and straw yield (2916 kg ha-1) as compared to no crop residue retention.

“…The pods per plant were significantly higher in plots receiving application of pendimethalin (1 kg a.i./ha as PPI). Better growth and development under these treatments resulted in more flowers and better fertilization, which in turn favoured more pod formation as confirmed by Sneha (2019). However, hand weeding done at 30 DAS had the highest number of pods/plant due to timely removal of weeds coupled with pulverization of soil, which encouraged better growth and development of flowers including their fertilization and finally recorded maximum pods per plant (Chaudhary et al, 2005 andChandrakar et al, 2015) .…”

Chickpea is a major pulse crop which is grown and consumed by the Indian people. Due to poor weed competition ability of chickpea and very few weed management options, yield of chickpea is drastically reduced under vertisols. Therefore, the present study related to weed management and crop residues on weed incidence, yield attributing character and yield of chickpea was conducted at Research Farm of JNKVV, Jabalpur (MP), India. A field experiment was undertaken in split plot design with 3 replications and 4 weed-management treatment in main-plot and four crop residues as sub-plot. The main plot treatments were pendimethalin 38.7% CS at 1 kg/ha as pre plant incorporation (PPI), hand weeding at 30 days after sowing (DAS), hand hoeing at 30 DAS and weedy check. Four crop residues mulch (CRM) were, wheat straw (WSM), paddy straw (PSM) and soybean haulm (SHM) each at 5 t/ha and control where no mulch material was applied. Results revealed that imposition of hand weeding at 30 DAS recorded with least weeds with lesser weed biomass resulting in higher weed control efficiency (WCE). However, weedy check recorded maximum weed count and dry weight. Pendimethalin 1 kg/ha recorded lower weed prevalence and weed dry weight. It was similar to hand hoeing done at 30 DAS. Among applied CRM, PSM recorded lower weed density and dry weight with higher WCE and soil moisture at 30 DAS and was superior over control plots. Hand weeding at 30 DAS recorded with higher yield attributing traits viz, pods/plant, seed/pod and seed index resulted higher seed yield (1,604 and 1,731 kg/ha respectively in 2018–19 and 2019–20). It was at par with pendimethalin at 1 kg/ha. The lower yield attributes and yield was recorded in weedy check plots. Among CRM, spreading of PSM give more pods and seeds/pod with higher seed index resulted in higher seed yield (1515 and 1593 kg/ha in 2018–19 and 2019–20 respectively) over others. Thus, application of PSM at 5 t/ha with one hand weeding at 30 DAS or with pendimethalin can be suggested for significant weed control and higher seed yield in chickpea.
