| dc.description | Wheat (Triticum aestivum L.) is one of the most important agricultural food
and feed crops worldwide. Wheat supplies about 20% of the energy and
about 25% of the protein requirements of the world population (Evans,
1998). An additional contribution to the human diet is via the nutrition of
animals that provide milk and meat. Wheat is such a widely grown crop
because it can be used for a wide variety of food products (e.g. bread,
cakes, cereals, beer etc.) and secondary products (e.g. starch, gluten etc.)
(Hoegy and Fangmeier, 2008). | en_US |
| dc.description.abstract | An experiment was conducted in the Soil Science research field of Hajee Mohammad
Danesh Science and Technology University, Dinajpur during the period of December
2016 to April 2017 in order to investigate the effect of different levels of Boron (B) on
the growth, yield and yield contributing characteristics of wheat (BARI Gom 28). The
experiment was laid out in a Randomized Complete Block Design (RCBD) having seven
treatments with three replications. The treatments were as follows; T1 = 0 kg B ha-1
(control), T2 = 0.5 kg B ha-1, T3 =1.0 kg B ha-1, T4 =1.5 kg B ha-1, T5 = 2.0 kg B ha-1, T6
=2.5 kg B ha-1, T7 =3.0 kg B ha-1. Total amount of TSP, MOP, gypsum, and 1/3 urea
fertilizers were applied as basal @ 140, 105, 117, 160 kg ha-1 and boron was applied
several treatments respectively at the time of final land preparation. The rest urea were
splited into two equal amounts and applied at crown root initiation stage and booting
stages. The experimental soil belongs to the Old Himalayan Piedmont Plain (AEZ-1).
The soil was sandy loam in texture having pH 5.6, organic matter content 1.58%, total N
0.08%, available P 59.72 ppm, exchangeable K 0.21 meq100 g-1 soil, available S 7.01
ppm and available B 0.76 ppm content in the soil. The experimental results were
statistically significant to plant height, spike length, number of plants m-2, number of
spikelets spike-1, number of grains spike-1
, grain yield, straw yield, biological yield
except 1000-grain weight. The results revealed that the highest plant height (94.87 cm)
was observed in T3 treatment and the lowest (89.60 cm) was found in the control T1
treatment. The maximum number of plants (337.2 m-2) was obtained in the treatment T3
and minimum (270.7) was found in the control T1 treatment. The highest number of
grain (42.10) was found in the treatment T3 and the lowest number of grain (36.23) was
recorded in the control T1 treatment. Grain yield and straw yield of wheat plants were
significantly influenced with the application of B. It was found that the application of
(1.0 kg B ha-1) produced the highest grain (4.23 t ha-1) and straw (4.13 t ha-1) yield. The
control treatment produced the lowest grain (2.37 t ha-1) and straw (3.0 t ha-1) yield. The
findings of the study showed that the performance of the treatment T3 was the best
among the other treatments in respects of yield and yield contributing characters of
wheat. Therefore, the overall results indicate that the application of (1.0 kg B ha-1) can be
more efficient and economic for wheat cultivation. | en_US |
