Effect of supplemental application of nitrogen, irrigation and hormone on the yield and yield components of Chickpea

In order to study the response of chickpea varieties to supplementary nitrogen, irrigation and hormones on the yield and yield attributes, a field experiment was conducted in December, 2012 to March, 2013 at Sher-e-Bangla Agricultural University, Dhaka, Bangladesh. The different supplementary treatments showed significant effect on number of pods plant 1, seeds pod 1, 1000-seed weight, shelling percentage, seed yield, stover yield, biological yield and harvest index of chickpea varieties. Among the varieties, the highest pods plant 1 (27.58), seeds pod 1 (1.65), 1000-seed weight (263.36 g), shelling percentage (0.69), seed yield (1702 kg ha 1), stover yield (2727 kg ha 1), biological yield (4429 kg ha 1) and harvest index (38.28%) were recorded from BARI chola 9. The maximum pods plant 1 (28.52), seeds pod 1 (1.67), 1000-seed weight (274.00 g), highest shelling percentage (0.73), seed yield (1851 kg ha 1), stover yield (2830 kg ha 1), biological yield (4681 kg ha 1) and harvest index (39.48%) were obtained from supplemental irrigation along with aqueous N before flowering. In case of treatment combinations, BARI chola 9 cultivation with applying supplemental irrigation before flowering + aqueous N before flowering revealed maximum yield and yield contributing characters. It would suggest that both the yield and the yield parameters seem to be favorably affected by supplementary nitrogen, irrigation and hormone application.
