“…The weedy check treatment had negative monetary returns and BC ratio (`4711 and 0.74) due to the heavy weed infestation in the weedy check treatment which, drastically reduce the seed yield of the green gram. The results were in conformity with the findings of Poornima et al (2018) and Tamang et al (2015). The interaction effect of land configuration and weed management was found non-significant.…”

To study the effect of land configuration and weed management on yield and yield attributes of green gram, a field experiment was conducted at Hisar during kharif 2016 in strip plot design with four replications. Ridge method of planting recorded significantly higher number of branches plant-1, seeds pod-1, 100 seed weight and seed yield in comparison to flat method of planting. Among the weed management practices, application of pendimethalin 30 EC @ 1.0 kg/ha-PE fb imazethapyr 10 % SL @ 55 g/ha at 15-20 DAS recorded significantly higher number of branches plant-1, seeds pod-1, pods plant-1 and 100 seed weight compared to weedy check. Similarly the same treatment recorded higher yield to the tune of 236, 48 and 18 % over weedy check, pendimethalin 30 EC @ 1.0 kg/ha-PE and Imazethapyr 10 % SL@ 55 g/ha at 15-20 DAS, respectively. Highest net returns (` 24632/ha), BC ratio (2.15) and weed control efficiency (94 %) was also recorded when pendimethalin 30 EC @ 1.0 kg/ha-PE fb imazethapyr 10 % SL @ 55 g/ha at 15-20 DAS of green gram crop was applied.

“…The higher weed control efficiency under these treatments could be attributed to the lower weed population and total weed dry matter as well and further it may contributedto highergrain yield. These results corroborated with the finding of Sangwan et al (2016) [15] , Poornima et al (2018) [12] and Vaghela et al (2018) [21] .

“…number of the weed m -2 of a particular weed specieswas recorded at 50 DAS, and differed significantlywith the different weed management treatments (Table-1&2). Density of monocot weeds (Cynodon dactylon, Cyperus rotundus, Echinochloa colona, Brachiaria reptans, Dinebra retroflexa, Dactyloctenium aegyptium) were much higher than the density ofdicot weeds Amaranthus viridis, Commelina benghalensis, Digera arvensis, Trianthema portulacastrum, Physalis minima at throughout thecrop growing season, as because rainy season ishighly favourable for grass and sedge population,similar opinion also reported by Poornima et. al.…”

“…Species wise predominant weed count, weed biomass, weed control efficiency were recorded at 50 days after post emergence spray (DAS), and finally the crop yield was measured at the time of harvest. Uniform application of 25 kg N ha -1 through urea and DAP (after adjusting the amount of N supplied through DAP) and phosphorus as per treatment through DAP was applied at sowing time through drilling [17] , Yadav et al (2017) [24] and Poornima et al (2018) [12] .…”

Background: Adequate tillage checks and delays the emergence of weeds and provides a more favourable environment for early crop establishment. Slow growth of crop plant provides favourable environment for emergence of weeds. Cultural as well as mechanical practices such as hand weeding and intercultural are effective but unavailability of labour and continuous rainfall in rainy season does not permit for timely management of weeds Chemical weed control is effective weed management option which provides effective control of weeds. It is well known that weeds are ubiquitous but their presence in cropped area particularly in rainy season crops like clusterbean act as major limiting factor in achieving high potential yield. The current study aimed to study the impact of crop establishment methods and weed control practices on productivity and profitability of clusterbean. Methods: A field experiment was carried out to find out suitable method of crop establishment methods and weed management practices in clusterbean during kharif seasons of 2018, 2019 and 2020. The experiment was conducted in spilt plot design with three replications. The treatments were four crop establishment methods viz., conventional sowing, zero tillage sowing, broad bed sowing, zero tillage sowing with mulch as main plots and four weed control practices viz., weedy check, pendimethalin+imazethapyr 1000 g ha-1, T3- Imazethapyr 40 g ha-1, T4-Imazethapyr+imazamox 40 g ha-1 as sub plot treatments . Result: The broad bed sowing of clusterbean along with pre-emergence application of pendimethalin+ imazethapyr 1000 g ha-1 was found effective to achieve higher productivity and farm profitability.
