Abstract: The effect of weed management practices on irrigated field pea (Pisum Sativum L) crop was conducted at the Agricultural Research Farm of B. H. U. Varanasi, during rabi season of 2010-11. The experiment was conducted in randomized block design (RBD) with 10 weed management treatments. The soil of experimental field was sandy clay loam in texture, with slightly alkaline in reaction (pH 7.8). The yield attributes viz., pods plant-1, grains pod-1, seed index (100-grain weight), grain yield, harvest index were recorded after harvest of crop. Experimental field was dominated by narrow leaved weeds which constituted 37.6 per cent and species wise were Cyperus rotundus L. (14.1%) and Parthenium hysterophorus L. (23.5%). Whereas, broad leaved weed species Melilotus alba (7.0%), Solanum nigrum L. (11.8%), Chenopodium album L. (35.3%), Anagallis arvensis L. (5.9%) and Vicia sativa L. (2.4%) accounted for 72.4 per cent of weed of total weed species. Among herbicidal treatments, sequential application of pendimethalin 1kg ha-1 (PE) + imazethapyr 50 g ha-1 (PoE) was proved to be the most effective in reducing the weed density and dry weight. It also recorded maximum weed control efficiency. The crop yield and yield attribute were maximum in pendimethalin 1kg ha-1 (PE) + imazethapyr 50 g ha-1 (PoE) treated plot followed by pendimethalin 1kg ha-1 (PE) + imazethapyr 75 g ha-1 (PoE) and quizalofop- ethyl 60 g ha-1 (PoE).
