ABSTRACT
A field trial was done on a medium textured soil to notice the return of wheat crop to model based applied fertilizer B. For this idea, B adsorption isotherm of the soil was developed at the Institute of Soil and Environmental Sciences, University of Agriculture, Faisalabad, during 2013-14. Adsorption procedure was done by harmonizing 2.5g soil in 0.01M CaCl2 solution having diverse B doses (0, 0.01, 0.03 , 0.05 , 0.07, 0.09, 0.11, 0.13,0.15 and 0.17 mg B L-1). Freundlich and Langmuir adsorption models were applied to the data to check the sorption of B on sandy clay loam soil. Freundlich model depicted superior fitness of the sorption (r2=0.99) statistics than Langmuir model (r2=0.75). Ten B treatments (0, 0.47, 0.81, 1.42, 1.57, 1.95, 2.35, 2.66, 3.1, 3.3 kg ha-1) were applied with recommended N, P and K doses. Boron was applied at sowing time as basal dose. The results showed that there was a positive effect of fertilizer B on grains spike-1, 1000-grain weight and grain turn out however, the vegetative growth i.e. plant height, tillering and total biomass were affected non-significantly in response to B application. Regarding chemical analysis concentration of boron in both wheat straw and grains increased with B application but there was no effect of fertilizer B on NPK concentration of straw and grains. These results are very heartening; signifying that for any soil, B adsorption isotherm need to be worked out for location precise fertilizer B use.
