Studies were conducted to understand whether application of water-soluble fertilizers through
foliar sprays during the vegetative stage can enhance the yield of maize and whether application
of micro (zinc) and beneficial elements (selenium) can help in influencing some of the plant
physiological processes and in-turn help minimize the yield reduction due to drought/insufficient
soil moisture.
Methodology
A field experiment with maize cv. DHM 117 was carried out in kharif at Gungal Research Farm
(GRF) in randomized block design with nine treatments and three replications. The treatments
tried were: 1) T1: recommended dose of fertilizer ie 90:45: 45 kg NPK/ha, 2) T2: T1 without top
dressing of 45 kg N/ha at 25 DAS+ foliar spray of 0.5% water soluble fertilizer + 0.5% ZnSO4
