ABSTRACT
An investigation was conducted during winter seasons of 2007-08 and 2008-09 on sandy loam soil at G.B. Pant University of Agriculture & Technology, Pantnagar to study the weed dynamics and seed yield of fieldpea under different planting methods, irrigation levels and weed management practices. Results revealed that density and dry matter of weeds/unit area, yield attributes as pods/plant, 1000-grain weight, grain yield/plant and grain yield of fieldpea were significantly higher under raised bed planting as compared to flat bed. Planting on raised bed increased grain yield of fieldpea by 17.5% over flat bed. Two irrigations applied at critical stages i.e. pre-flowering and pod formation proved promising in increasing the yield attributes and grain yield of pea. In weedy check, Cyperus rotundus and Cirsium arvense constituted 26.4, 29.5, 31.1% and 15.1, 19.5, 16.5% of total weed flora counted at 60, 90 and 120 days after sowing, respectively. One hand weeding done at 25 days after sowing (DAS) reduced the density and dry matter of weeds significantly and increased the values of yield attributes and grain yield as compared to pendimethalin 1.0 kg/ ha applied as pre-emergence and weedy check.
Key words: Fieldpea, Planting method, Irrigation levels, Weed management
