Abstract
The present investigation entitled “Effect of sowing methods and moisture
regimes on productivity of timely and late sown varieties of wheat (Triticum
aestivum. L)” was conducted at Agronomy Research Farm, of Acharya Narendra Deva
University of Agriculture & Technology, Narendra Nagar, (Kumarganj), Ayodhya (U.P.)
during Rabi season of 2017-18 and 2018-19. The experiment were laid out in split plot
design having two wheat varieties (PBW-343 and HUW-234) and three moisture regimes
i.e. Irrigation at 0.8 IW/CPE ratio (I1), Irrigation at 1.0 IW/CPE ratio (I2) and irrigation at
CRI, late jointing and flowering stage (I3) with 6 cm depth of each irrigation were
allotted as main plot and three sowing methods i.e. Broad casting (S1), Seed drill (S2) and
Furrow irrigated raised bed (S3) kept as sub plot. The experiment was replicated three
times on silty loam in texture soil and medium in fertility status having pH (8.3,8.20),
organic carbon (0.33,0.32%), EC (0.25,0.24) dsm-1, available nitrogen (137.60,136.82 kg
ha-1), available phosphorus (15.20,14.70 kg ha-1) and available potassium (249.30,248.32
kg ha-1). The experiment data revealed that the growth parameter likes; plant height, dry
matter accumulation and leaf area index were recorded significantly higher with timely
sown variety of PBW-343 followed by late sown variety of HUW-234. The same trend
was found with moisture regime at 1.0 IW/CPE as compared to Irrigation at 0.8 IW/CPE
ratio and irrigation at CRI, late jointing and flowering stage. In case of sowing method,
the maximum growth and yield under furrow irrigated raised bed (FIRB) method of
sowing as compered to Broad casting and Seed drill at successive stages of wheat crop.
The yield attributes and yield likes; ei. Number of spikes (m-2), Spike length (cm),
Number of grains spike -1, test weight and yield under the variety of PBW-343 which was
followed by HUW-234.The maximum values of yield attributes and yield were recorded
with Irrigation at 1.0 IW/CPE ratio than Irrigation at 0.8 IW/CPE ratio and irrigation at
CRI, late jointing and flowering stage.
