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