| dc.description.abstract | An experiment was conducted at Agronomy Research Field of the Department of
Agronomy, Hajee Mohammad Danesh Science and Technology University, Dinajpur
during 2016-2017 in Rabi season with a view to examining the effect of seed fertilization
and foliar application of urea with nutrients solution on the germination, seedling
growth, yield components and yield of wheat to save urea fertilizer. The experiment was
laid out in a randomized complete block design (RCBD) with three replications. The
treatments comprised as T1 (Control), T2 (NS 5ml/kg seed with 40ml H2O + NSA50% +
NFA10% + NS 4ml), T3 (NS 5ml/kg seed with 5ml H2O + NSA50% + NFA10% + NS 4ml), T4
(NS 10ml/kg seed with 40ml H2O + NSA50% + NFA15% + NS 4ml), T5 (NS 10ml/kg seed
with 5ml H2O + NSA50% + NFA15% + NS 4ml), T6 (NS 15ml/kg seed with 40ml H2O +
NSA60% + NFA10% + NS 4ml), T7 (NS 15ml/kg seed with 5ml H2O + NSA60% + NFA10% + NS
4ml), T8 (NS 20ml/kg seed with 40ml H2O + NSA60% + NFA15% + NS 4ml), T9 (NS 20ml/kg
seed with 5ml H2O + NSA60% + NFA15% + NS 4ml), T10 (N100%). Data were recorded on
different growth and yield contributing parameters. Germination percentage, crop growth
rate, SPAD value, plant height, spike length, number of effective tillers hill-1 and number
of filled grains spike-1, 1000-grain weight, grain yield, straw yield, biological yield and
harvest index of wheat. The results revealed that the highest germination percentage
(72.2%), SPAD value (48.77), plant height (94.17cm), number of effective tillers hill-1
(9.00), number of filled grain spike-1 (56.67), 1000- grain weight (58.13 g), grain yield
(5.62 t ha-1), straw yield (4.74 t ha-1) as well as biological yield (10.35 t ha-1) was
recorded from T9,T8 and T3. The treatment T9, T8 and T3 were found to be better
treatments in terms of obtaining higher germination, seedling growth as well as grain
yield. The effect of T9 treatment was specially remarkable for achieving higher yield of
wheat and in the economic point of view. It also indicated that seed fertilization and
foliar application of urea coupled with nutrients solution were better performance for
obtaining maximum yield and yield components of wheat (BARI Gom 30) by saving 25
- 40% urea fertilizer than traditional method. Considering the findings at least, 25% urea
was saved from the T9 treatment combination. | en_US |
