Abstract

An experiment was carried out at EL-SerwAgricultural Research Station, Agricultural Research Center, at Damietta Governorate, Egypt during 2018/19and 2019/20 winter seasons to estimate the critical period of field pea/weed competition under two seeding rates. The experiment included 20 treatments which were the combination of two seeding rates (25 and 35 kg seeds/fed.) and 10 weed competition treatments which were weed-free period at 2, 4, 6 and 8 weeks after sowing (WAS) as well as whole season weed free, and weed competition treatments at 2, 4, 6 and 8 weeks after sowing (WAS) as well as whole season-weed competition. The experimental design was a split- plot design where the two seeding rates were allocated to the main plot and the weed competition treatments were allocated to the sub-plots.
Results indicated that increasing seeding rate from 25 kg seeds/ fed. up to 35 kg seeds/fed decreased significantly broad-leaved, grass and total annual weeds dry weight in both seasons, while it increased plant height, green pods yield and dry seed yield by 7.08, 13.18 and 15.73%, in the first season, and 10.09, 13.07 and 11.22%, in the second season, respectively, compared with 25 kg seeds/fed. However, the number of branches/plant, number of pods/ plant, pods' weight/ plant, number of seeds/ pod and 100 seeds weight were significantly decreased. Increasing the period of early weed competition more than two weeks and/or decreasing the late weed competition to more than 6 weeks can decrease significantly the seed yield. Results indicated that the interaction between seeding rates and weed removal periods was significant in both seasons in their effect on all weed categories. Whole season weed free and seeding rate 35 kg seeds/fed. gave the highest reduction in all weed categories dry weight and gave the highest green pods and dry seed yields in both seasons.
The critical period of field pea-weed competition was 2-6 weeks after sowing under seeding rate of 25 kg seeds/fed. and 3-6 weeks after sowing under seeding rate of 35 kg seeds/fed.
