The objective of this study was to evaluate the effectivity of combination of some integrated weed management methods on yield and yield components of chickpea (Cicer arietimum L.) cv. Bivanij.
The experiment was conducted as a factorial in completely randomized block design with 15 treatments each in four replications. The experimental factors included herbicide applications consisting of untreated herbicide, and pyridate; plant densities of 30, 40,and 50plants m-2; and cultivations including uncultivated and cultivated for once. In addition, three full-season handweedings each for corresponding plant density treatment was applied.
The dry weight of weed biomass was decreased respectively 95 and 60%, 30 days after pyridate application and cultivation; while using combination of these two methods reduced them up to 99 percent. Pyridate application increased height and grain yield by 1.3 and 2.5 times, and cultivation increased pod number per plant and grain yield by 37and 31%, respectively. In pyridate treated of 30 plants m-2 treatment, the highest pods per plant, seeds number and weight per plant, and plant dry weight were respectively 2.7, 3.1, 3.9, and 2.6 times more than those of untreated pyridate treatments. Seed yield of chickpea with the combined application of pyridate and cultivation at the density of 50plants m-2 did not have significant differences with weed free treatments (all three densities of 30, 40 and 50plants m-2).
Integrated application of pyridate and cultivation at the chickpea density of 50 plants m-2 can be beneficial to achieve the desired yield in dryland conditions, and, hence, is recommendable.
