Nodulation and nutrient accumulation of chickpea as influenced by weed management.
In a trial in chickpeas (Cicer arietinum) cv. ICCC 4 carried out during rabi on a clayey soil infested mainly with Brachiaria spp., Echinochloa crus-galli, Cyperus rotundus, Cynodon dactylon, Chenopodium album and Digera arvensis significantly higher yields were obtained with hand weeding (30 and 45 days after sowing), fluchloralin at 0.9 kg/ha incorporated pre-sowing ± 1 hand weeding 30 DAS and isoproturon 0.75 kg pre-em. + 1 hand weeding 30 DAS. Manual weeding increased root nodule FW and DW, while all weed control treatments reduced nutrient uptake by weeds and increased that by the crop.
