Abstract
The aim of this study was to evaluate effect of planting pattern and integrated management on weed structure, yield and yield components of peanut. Main plot includes planting pattern in three levels (single row, two parallel rows and two zigzag rows) on 75 cm row, and sub plot includes 7 levels of weed management including (planting cover crops 1- crimson clover and 2- hairy vetch, chemical control: 3- application of bentazone + supergalant herbicides combination, 4- mechanical control: 4- weeding once (20 days after planting) and 5- weeding twice (20 and 40 days after planting), 6- weeding the total season of weeds and 7- the control without the use of cover crop and the use of herbicide.
The results of the experiment showed that the height of the plant, the number of branches, the chlorophyll index, weight of 100 seeds, seed yield, total density of weeds, and total biomass of weeds were influenced by weed control methods and planting patterns. The highest measured traits were obtained in the two-row zigzag planting arrangement and at different levels of weeding, and then in the treatments of hairy vetch, clover and herbicide application, and the lowest values of the mentioned traits were found in the single planting pattern and in without control. The highest density and biomass of weeds was in the single-row planting pattern and in without control and the lowest weed biomass was in the two-row zigzag planting pattern and in weeding twice or planting cover crops of hairy vetch.
