Abstract
A field experiment entitled “Response of wheat to foliar application of water soluble
fertilizers” was conducted during Rabi season of 2015-16 at Agronomy Research Farm of
Chaudhary Charan Singh Haryana Agricultural University, Hisar, Haryana. The soil of the
experimental plot was sandy loam in texture, low in available nitrogen (131.3 kg/ha), medium in
available phosphorous (17.2 kg/ha), and high in available potassium (335.4 kg/ha). The soil was
alkaline in reaction (pH 7.8). The experiment was laid out in randomized block design with 17
treatments having three replication. The treatments comprising two fertilizers level i.e. RDF (150
kg N + 60 kg P2O5 + 60 kg K2O/ha) and 75% of RDF and supplemented with foliar application of
water soluble fertilizers viz. Urea phosphate (17:44) @ 1.5%, NPK (18:18:18) @ 1.5%, ZnSO4 @
0.5% and Urea 2% at different stages. One treatment was control where no fertilizer applied.
Growth parameters viz, plant height, dry matter accumulation, crop growth rate and leaf
area index were increased with T9 i.e. RDF along with foliar application of water soluble
fertilizers NPK (18:18:18) @ 1.5% at 40 DAS followed by Urea phosphate (17:44) @ 1.5% at 65
DAS. Yield attributes as well as yield, also improved significantly with T9 i.e. RDF along with
foliar application of water soluble fertilizers NPK (18:18:18) @ 1.5% at 40 DAS followed by
Urea phosphate (17:44) @ 1.5% at 65 DAS. However, alternate application of NPK (18:18:18) @
1.5% and Urea phosphate (17:44) @ 1.5% or vice versa produced statistically similar grain yield
of wheat at the same level of fertilizer application. The nutrients concentration and their uptake
and quality parameters were also higher in T9. The higher B:C ratio was found with RDF along
with foliar application of water soluble fertilizers NPK (18:18:18) @ 1.5% at 40 DAS and Urea
phosphate (17:44) @ 1.5% at 65 DAS but 75% of RDF and supplemented with alternate foliar
application of water soluble fertilizers NPK (18:18:18) @ 1.5% at 40 DAS followed by Urea
phosphate (17:44) @ 1.5% at 65 DAS was found more economical.
