Irrigation time and weed management to enhance productivity of chickpea (Cicer arietinum L.)
Sahaja Deva and SS Kolhe
Field experiment was carried out at
Research Farm, Indira Gandhi Krishi Vishwavidyalaya, Raipur (Chhattisgarh) during Rabi
seasons of 2013-14 and 2014-15 to study the effect of irrigation time and weed management practices on weed competition and growth, yield as well as economics of chickpea. Irrigation application before or after sowing of chickpea was observed equally effective for enhancing dry matter of chickpea, yield components viz
., number of pods/plant, number of seeds/pod, 100 seed weight, seed and haulm yield as well as harvest index. Similarly, weed competition in terms of dry matter of weeds, weed control efficiency and weed index was remained unaltered due to irrigation applied before or after sowing of chickpea. Among weed management practices, hand weeding twice was the best treatment in controlling weeds and produced the highest seed yield, haulm yield, gross returns and net returns as well as B: C ratio. Among herbicides, oxyfluorfen 0.3 kg/ha as pre-emergence was found significantly superior over other herbicides in producing dry matter, yield attributes, seed and haulm yield of chickpea and recorded the highest weed control efficiency (WCE). It also gave the higher gross return, net return as well as benefit: cost ratio than rest of the treatments. The minimum yield (0.90 t/ha) and the maximum weed index (47.82%) was recorded under untreated control.
