Growth and yield response of wheat to irrigation at different growing stages
Year: 2015
Type: preprint
Abstract: An experiment was conducted at the experimental field of Sher-e-Bangla Agricultural University, Bangladesh during November 2011 to March 2012 to study the growth and yield of wheat to irrigation stages. Four irrigation stages viz. I0: No irrigation; I1: Irrigation at crown root initiation (CRI) stage (18 DAS); I2: Irrigation at preflowering stage (45 DAS) and I3: Irrigation at both CRI and pre-flowering stage were used following Randomized Complete Block Design with three replications. Maximum number of tiller/hill (5.2), CGR (6.7 gm -2 day -1 ), RGR (0.03 gg -1 day -1 ), dry matter content (28.7%), number of spikes/hill (4.5), number of spikelets/spike (19.0), ear length (17.5), filled grains/spike (30.8), total grains/spike (32.9), weight of 1000-grains (47.1 g), grain yield (3.9 tha -1 ), straw yield (4.9 tha -1 ), biological yield (8.8 tha -1 ) and harvest index (45.9%) were found from I3 whereas minimum from I0. On the other hand, early flowering (70.6 days), maturity (107.2 days) and minimum number
