Abstract:
A study titled “Effect of weed control practices alone and in combination with crop mulch on weed dynamics, yield and economics of chickpea” was conducted at Live Stock Farm, Department of Agronomy, JNKVV in Rabi 2019-2020. Four weed control practices viz. Pendimethalin (38.7% CS) 1 kg a.i. /ha as PPI, hand weeding 30 DAS, hand hoeing 30 DAS and Control as a main plot treatments and four crop mulches i.e. Wheat straw (5 t/ha), paddy straw (5 t/ha), Soybeanstraw (5 t/ha) and Control (No mulch) were assigned in sub-plot treatments and these were laidout in a split plot design with three replications. In experimental area, Cichorium intybus (30.36%), Medicago truncatula (20.72%) Melilotus indica (19.52%) Anagalis arvensis (19.52) Chenopodium album (9.88%) was dominant weed species. Weed intensity and dry biomass slightly reduces in hand hoeing at 30 DAS over weedy check. Among weed control method, minimum weed count and weed biomass of total weeds were recorded in one hand weeding at 30 DAS higher weed control efficiency followed by pendimethalin 1 kg /ha as PPI over hand hoeing and weedy check. Among residue mulch paddy straw at the rate of 5 t/ha, significantly minimize weed count and weed dry biomass resulted recieved higher weed control efficiency (61.34%) followed by wheat straw mulch (53.04%). Lower chickpea yield (868 kg/ha) was seen in the weedy check. Among weed control treatment, higher seed yield (1731 kg/ha) was recorded in one hand weeding at 30 DAS followed by pendimethalin 1kg /ha (1561kg/ha). Higher seed yield (1593 kg/ha) was recorded in paddy straw 5t/ha followed by wheat straw mulch (1469 kg/ha).
