Abstract

Two field experiments were carried out on the yield of pea crop in soil naturally infested with annual weeds and broomrape (Orobanche crenata Forsk.), at Sakha Agricultural Research Station, Agricultural Research Center, Egypt, (31°07'N, 30°05'E) latitude. longitude) during the 2022/2023 and 2023/2024 winter seasons. This study was conducted to evaluate the effect of sowing dates (25th October and 25th November) and five weed control treatments on growth, yield components of pea as well as its associated weeds. A split plot design was used with four replicates. The main finding revealed that the studied two factors were dependent, The highest significant reduction percentage on controlling weeds included broomrape was obtained by using either of pea growing in 25th November with weed control treatments (Basagran at 0.5 L fed-1+ Select Super at 0.25 L fed-1 + Round up Star at 0.04 L fed-1 (twice)), (Alpha Top at 0.5 L fed-1 + Fuselied Forty at 1.4 L fed-1 + Round up Star at 0.04 L fed-1(twice)) and (Stomp Extra at 1.7 L fed-1 + Fuselied Forty at 1.4 L fed-1 + Round up Star at 0.04 L fed-1 (twice)), on controlling annual weeds, broomrape and on increasing pea yield and its components. The previous respective interactions gave the highest significant increasing values of pea seed yield (ton/fed), and its components in kafr El-Sheikh area.
