| dc.description.abstract | An experiment was conducted at research field and laboratory in the Department
of Crop Physiology and Ecology, Hajee Mohammad Danesh Science and
Technology University, Dinajpur, during the period of 20th November 2016 to 16th
March 2017 to study the effects of varietes and different planting directions on
growth and yield of wheat. Five varieties viz. V1=BARI Gom-26, V2=BARI Gom27, V3=BARI Gom-28, V4=BARI Gom-29 and V5=BARI Gom-30 and two
planting directions viz. G1= North- South, G2=East-West were included in this
study. The experiment was carried out in a randomized complete block design
with three replications. Results showed that varieties had significant effects on
plant height, total tillers hill-1, number of effective tillers hill-1, number of noneffective tillers hill-1, grain yield, TDM, LAI, CGR, RGR, NAR and biological
yield. The highest plant height (109 cm), total tillers hill-1 (6.83), number of
effective tillers hill-1 (6.43), number of non-effective tillers hill-1 (0.41), spike
length (16.87 cm), leaf area (1858.29 cm
2
) hill-1, relative leaf water content
(136.66), moisture retention capacity (73.02%) and canopy temperature (21.93
C) were observed in V5 (BARI Gom- 30). The maximum TDM, LAI, CGR,
RGR, 1000-grain weight (55.63 gm), grain yield (3.55 t ha-1) and bilogical yield
(7.99 t ha-1) were recorded from V5 (BARI Gom-30). Different planting directions
also showed significant effects on most of the parameters. The highest TDM,
RGR and NAR were obtained from G1 (North-South) planting direction. The
highest grain yield (3.11 t ha-1) was recorded from G1 (North-South) while the
lowest grain yield (2.80 t ha-1) was recorded from G2 (East-West). The highest
grain yield (4.10 t ha-1) was obtained from G1×V5 while the lowest grain yield
(2.70 t t ha-1) were obtained from G2×V2. Results of the present study revealed that
N-S with BARI Gom-30 combination was the best for obtaining maximum grain
yield of wheat. | en_US |
