Abstract
A field experiment was conducted during the winter season of 1999-2000 and 2000-2001 to study the influence of different weed-control methods under different levels of nutrients application on weed dynamics and seed yieldof sole gram or chickpea (Cicer arietinum L.) and gram + Indian mustard [Brassicajuncea (L.) Czemj. & Cosson] (4:2) intercropping system. No significant variation in the density and biomass of purple nut sedge (Cyperus rotundus L.), lambsquarters (Chenopodium album L.) and pimpernel (Anagallis arvensis L.) was observed in both the cropping systems. Also both the cropping systems did not influence gram-equivalent yield. No consistent response was noticed in terms of weed infestation and gram-equivalent yield due to higher dose of nutrient (20:60:40kgN:P:K/ha) application in both the years. Significantly reduced total weed biomass (2.92 g/0.25 m 2 ) with manual weeding 25 and 45 days after sowing in comparison of weedy check (31.67 g/0.25 m 2 ) was observed. The increase in seed yield of gram (92.5-116.5%), Indian mustard (16.5-47.5%) and gram-equivalent yield (75.5-89.0%) by different weed-control techniques over weedy check was found in both the years. Pre-emergence applied pendimethalin at 1.25 kg/ha helped to attain 45.2% more gram-equivalent yield over weedy check, with a mean increase in gross additional return of 41.6% over the check.
