Abstract
Boron (B) is vital for crops and helps in grain setting, but its deficiency is increasing due to its fixation in
calcareous soils of Pakistan which results in premature opening of spikelets and failure of grain production in
wheat thus leading to the reduced crop yield and economic return. To overcome this problem, a field trial was
carried out at Agronomy Research Farm, University of Agriculture Faisalabad for analyzing the effectiveness of
different levels of B spray on wheat. Randomized complete block design (RCBD) with three replications was used
for allocation of treatments. Treatments included were eight levels of B (0.5%, 1%, 1.5%, 2%, 2.5%, 3%, 3.5%, 4%)
along with water spray and control (without any treatment). Boron solution of different concentrations was
prepared by dissolving required quantity of boric acid in water. Foliar application of 1.5% B solution produced
maximum spike length (12.66 cm), grains spike-1 (50), seed index/1000-grains weight (35g), biological yield (9.85 t
ha-1
), grain yield (4.72 t ha-1
), harvest index (47.88 %), proteins (11.90 %), carbohydrates (66.96%) and benefit to
cost ratio (1.31) when compared with all other levels. Overall, it is depicted that 1.5% B applied by foliar spray at
booting stage triggered both yield and quality of wheat.
