Abstract:

A field experiment was conducted during two consecutive seasons of rabi 2011-13 at Crop Research Centre of G.B. Pant University of Agriculture and Technology, Pantnagar to find out the effect of planting pattern and weed management practices on weed growth and yields of field pea and baby corn in field pea (Pant P-13) + baby corn(Surya) intercropping system. The experiment was laid out in split plot design keeping four planting patterns as main plot and four weed management practices as sub plot with three replications. Paired planting of maize (30/60 cm) + field pea (2:2) and planting of maize + field pea (1:1) had lower total weed density and weed dry weight and higher weed control efficiency than sole planting of field pea or baby corn. Sole planting of field pea recorded significantly higher grain (2264 and 1434 kg ha-1) and straw yields(3263 and 2540 kg ha-1) during 2011-12 and 2012-2013than yield obtained as a component crop in paired planting of maize (30/60 cm) + field pea (2:2) and planting of maize + field pea (1:1).Baby corn yield was similar in sole, paired (2:2) and 1:1planting but significantly higher stover yield of baby corn(3576 kg ha-1and 3533 kg ha-1,during 2011-12 and 2012-2013 respectively)was obtained from sole crop than other planting methods during both the years. Both the intercropping systems had significantly higher field pea equivalent yield than sole crop of either field pea or baby corn. The lowest total weed density(66.5 and 67.3plants/m2,during 2011-12 and 2012-2013 respectively) and weed dry weight (99.4 and 99.7g m-2,during 2011-12 and 2012-2013 respectively) was recorded in hand weeding at 90 days after sowing which was followed by pre-emergence application of pendimethalin 1 kg ha-1, post-emergence application of imazethapyr 50 g ha-1 and weedy check. Significantly higher weed control efficiency was recorded from one hand weeding (56.07 and 56.52%)and pre-emergence application of pendimethalin 1 kg ha-1(55.37and 56.49%) during 2011-2012and 2012-2013 than post emergence application of imazethapyr 50 g ha-1(30.08 and 30.36% respectively). Hand weeding, pre-emergence application of pendimethalin 1 kg ha-1 and post-emergence application of imazethapyr 50 g ha-1 (30 days after sowing) improved all the growth and yield parameters of field pea and baby corn than weedy check. Hand weeding, pre-emergence application of pendimethalin 1 kg ha-1 and post-emergence application of imazethapyr 50 g ha-1 had significantly higher field pea equivalent yield than weedy check.
