The present investigation entitled “Response of Kharif onion (Allium cepa L.) for growth and yield to different doses of Sulphur, GA3 and NAA” was carried out during kharif 2016 –17 (first year) and 2017 – 18 (second year) at the experimental field RVSKVV, Krishi Vigyan Kendra, Rajgarh (.) with 27 treatment combinations of three levels of sulphur . 0, 20 and 40 kgha-1 , three levels of Gibberellic acid viz., 0, 50 and 100 ppm and three levels of NAA . 0, 50 and 100 ppm. Results obtained for 2016-17 and 2017-18 and in pooled basis revealed that the application of 40 kg S ha-1 was recorded significantly maximum plant height, number of leaves per plant, bulb/ green top ratio and neck diameter and yield attributes such as fresh weight of bulb, polar and equatorial diameter of bulb and bulb yield per hectare in both the year and in pooled. Foliar application of GA3 @ 50ppm (G1) and NAA @ 100 PPM (N2) at seedling stage and after 30 days after transplanting also exhibited significantly maximum growth and yield. It was concluded that various growth and yield parameters were improved with the application of S 40 Kg/ha+ GA3 50 ppm + NAA100ppm for higher yield and quality of Kharif Onion. | Response of Kharif Onion (Allium cepa L.) for growth and yield to different doses of sulphur, GA3 and NAA
