Abstract:
In this study “Response of Sulphur aerosols on morphological traits in wheat (Triticum aestivum L.)” was conducted to find out effect of 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 five wheat genotypes (viz., GW-322, GW-366, GW-273, GW-173, JW-336). 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. However, the total concentration of each of the S-aerosols was 900 ppm ≈ 0.9% were carried out under pot (October, 2017-March, 2018) (Expt.1) and field (October, 2018-March, 2019) (Expt.2). Foliar misting of S-aerosols affects the physiological traits both in field and pot experiment which was confirmed by the significant changes at maximum tillering and spike initiation stages of effective tillers (5.7-12%), plant height (6.5-10.6%) at harvest pot experiment effective tillers (0.11-5.8%), plant height (3.2-6.2%) at harvest stage in field. The genotype GW-366 was the most responsive for effective tillers & plant height. Among the S-aerosols, (NH₄)₂SO₄ was the most effective for all the traits in the work. The aim of the study is find out effect of sulphur aerosols using PCA principle component analysis.
