An experiment was conducted in rabi season to study the weeds and yields of greengram as influenced by irrigation scheduling and weed management during 2018-19. Fifteen treatment combinations comprising three irrigation schedules viz., irrigations at flowering, irrigations at flowering and pod development and irrigations at branching, flowering and pod development stage; five weed management practices viz., Pendimethalin CS, Quizalofop-P-ethyl, Pendimethalin CS (PE) fb Quizalofop-P-ethyl (PoE), 2 HW at 20 and 40 DAS and unweeded check. were Echinochloa spp., Trianthema portulacastrum, Digera arvensis. Physalis minima, Convolvulus arvensis and Cynodon dactylon. were found as major weeds in experiment. The growth and yield attributes viz. plant height, number of branches/plant, dry matter accumulation, number of pods/plant, number of seeds/pod and 1000 seed weight were recorded significantly higher under Irrigations each at branching, flowering and pod development stage, ultimately produced higher seed and stover yield. Further, application of Pendimethalin CS 1 kg/ha significantly minimized the weed density and dry weight of weeds, resulted higher growth and yield of green gram crop. Whereas, weeds cause 58.8% yield losses under unweeded control. On the basis of interaction, it is inferred that irrigating the crop at branching, flowering and pod development and managed the weeds either through Pendimethalin CS 1.0 kg/ha (PE) or 2 HW at 20 and 40 DAS.
A field experiment was conducted during the summer seasons of 2013 and 2014 in Vertisol soil to evaluate the fruit yield and weed dynamics influenced by weed management practices at the College Farm, N.M. College of Agriculture, Navsari Agricultural University, Navsari. Results showed that three hand weeding (HW) at 20, 40 and 60 days after sowing (DAS) recorded significantly higher weed control efficiency with minimum weed population. All growth and yield attributes were significantly higher under three HW at 20, 40 and 60 DAS. Consequently, higher fruit yield (16.78 t/ha) was also registered with three HW at 20, 40 and 60 DAS and remained at par with two HW at 20 and 40 DAS and pendimethalin 1.0 kg/ha as pre-emergence + quizalofop-ethyl 0.04 kg/ha at 30 DAS. For achieving higher and profitable fruit yield, two HW at 20 and 40 DAS found appropriate. However, under a scarce labour situation, application of pendimethalin 1.0 kg/ha as pre-emergence + quizalofop-ethyl 0.04 kg/ha at 30 DAS was also found remunerative.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
