Abstract:
A field experiment was conducted at the Agronomy Research Farm, Acharya Narendra Deva University of Agriculture and Technology, Kumarganj, Ayodhya (U.P.), India, during the Rabi season 2016-17 to access the “Influence of integrated weed management on growth attributes and quality of Indian mustard (Brassica juncea L.)”. The experiment comprised of ten treatments viz. pendimethalin (PE) 1.0 kg/ha, isoproturon (POE) 1.20 kg/ha, pendimethalin (PE) 1.0 kg/ha + hand weeding at 45 DAS, isoproturon (POE) 1.20 kg/ha + hand weeding at 45 DAS, pendimethalin (PE) 1.0 kg/ha + straw mulch 5 t/ha, isoproturon (POE) 1.20 kg/ha + straw mulch 5 t/ha, straw mulch 10 t/ha (3 DAS), two hand weeding at 20 and 40 DAS, glyphosate 0.5 ml/liter of water at 20 and 40 DAS and weedy check respectively with three replication was conducted in Randomized Block Design. The results revealed that two hand weeding at 20 and 40 DAS was at par with pendimethalin (PE) 1.0 kg/ha + straw mulch 5 t/ha and gave higher plant height (181.39, 176.17 cm), with higher dry matter accumulation in g/plant (56.89, 54.18) respectively. Among of all treatments recorded highest number of primary and secondary branches/plant in two hand weeding at 20 and 40 DAS was at par with pendimethalin (PE) 1.0 kg/ha + straw mulch 5 t/ha (9.73, 9.71) and (21.93, 21.48) respectively. And also nutrient content, nutrient uptake, leaf area index as well as oil content and oil yield was found higher in two hand weeding at 20 and 40 DAS while at par with pendimethalin (PE) 1.0 kg/ha + straw mulch 5 t/ ha. Based on all the observations recorded, two hand weeding at 20 and 40 DAS fb pendimethalin (PE) 1.0 kg/ha + straw mulch 5 t/ha has performed better in all parameters amongst all the integrated weed managements practices.
