Abstract
The younger wheat leaves are fertilized with only nitrogen get started bright green or yellowish green colour. Furthermore, the plants suffering from sulphur deficiency persisted for more time reduces grain yield. Responses of nitrogen, calcium, and potassium along with sulphur. Foliar fed of sulphur aerosols viz., (NH4)2SO4, CaSO4, and K2SO4: @ 300 ppm each (≈30 kg N ha-1) along with a control were misted on the plants, on sunny days in the afternoon (after 2–3 P.M.) at three different growth stages i.e. seedling, maximum tillering and spike initiation stages can compensates yield losses. However, the grain yield is increased by application of Sulphur aerosols. Therefore, the total concentration of each of the S-aerosols was 900 ppm ≈ 0.9% on Genotypes (viz., GW-322, GW-366, GW-273, GW-173, JW-336) was accomplished both under Pot (Expt.1) and Field (Expt.2). The correlation studies revealed that Seed yield in GW-366 was positively correlated with no of spike plant-1, test weight, spike length, HI, straw yield, NUE, SUE both for field and pot experiments respectively. In case of aerosol treatments, (NH4)2SO4 brought positive and significant correlations between seed yield with no of spike plant-1, test weight, spike length, HI, straw yield, NUE, SUE. In this study the genotype GW-366 was the most responsive under the influence of foliar fertilization with S-aerosols. Among the S-aerosols, (NH4)2SO4 was the most effective in the work. Aim of the study application of Sulphur aerosols foliarly enhances juvenescence of crop plant, retarded blooming, physiological maturity, and yield.
