- Abstract
A study was conducted at Arid Zone Research Institute, Bhakkar, Pakistan during 2007-10 to observe the impact of canopy management on bio-economic efficiency of chickpea on sandy loam soil. Treatmetns comprising plant growth regulators i.e. Nephthalene Acetic Acid (NAA) was kept in main plots while four available moisture depletion levels (ASMDL 50, ASMDL 65, ASMDL 80 and ASMDL 95) were kept in sub-plots, using split plot arrangements. Naphthalene acetic acid (4.5% as sodium salt) was applied @ 600 ml per hectare at 90, 110, 130, 150 and 165 days after sowing. The results showed that NAA applied at flower blooming stage (90 days after sowing) significantly increased number of pods per plant, seeds per pod, 100-seed weight and seed yield by 12.50, 6.98, 9.59 and 13.98 percent, respectively compared with control (NAA0). Treatment combination NAA1 x ASMDL80 gave maximum pods per plant (70.68), 100-seed weight (30.15 g) and grain yield (3219.1 kg/ha). Water productivity ranged from 8.23 (ASDML50 x NAA0) to 18.18 kg per ha per min (NAA x ASSML95). Maximum dry matter accumulation was recorded at 150 DAS in case of both NAA levels. The application of 600 ml per hectare NAA at flower initiation and maintenance of irrigation at 80 percent ASMDL (total amount of water applied was 252 mm with irrigation depth of 126 mm each) proved best for higher chickpea seed yield with 4.28 BCR.
