Effect of weed management practices under irrigated condition growth and yield of field pea (Pisum sativum L)

Field pea (Pisum sativum L) crop was conducted at the Agricultural Research Farm of B. H. U. Varanasi, during rabi season 2010-11. The experiment in randomized block design (RBD) with 10 weed control treatments viz., pendimethalin 1.0 kg ha-1 (PE), (PE) + imazethapyr 75 g (PoE), quizalofop- ethyl 60 50 chlorimuron- 4 (PPI), 1kg (PoE) and free (HW 30 DAS) were compared weedy check two irrigation given to critical stages growth. soil experimental field application recommended dose fertilizer time sowing sandy clay loam texture, slightly alkaline reaction (pH 7.8). variety HUDP-15 sown row spacing cm apart on 11 November 2010. observation density dry matter accumulations recorded 30, 90 DAS. Weed efficiency calculated maximum weight stage (60 Among herbicidal treatments, sequential proved be most effective reducing weight. It also lower index. Observation plant height, yield attributes pods plant-1, grains pod-1, seed index (100-grain weight), grain straw yield. growth, attribute, yield, treated plot followed by (PoE).
