Abstract:
Field experiment was conducted at Department of Biological Sciences, Allahabad, Sam Higginbottom University of Agriculture, Technology and Sciences, Allahabad (U.P.) India during rabi season 2015-16 using Azotobacter in onion field. The results of field experiments revealed that at 100 DAT, soil pH of each treated plots vary from each other and treatment T5 and T6 has got lowest pH (7.2) as compare to all other treatments. Results of electrical conductivity showed that there was non significant difference in all the treatments ranging from 0.703dsm-1 to 0.708dsm-1. Similarly the maximum percent of organic carbon recorded in treatment T6 (0.57%) followed by T5 (0.52%) and lowest in treatment T1 (0.46%). The maximum amount of phosphorus content found in treatment T6 (25.4kg/ha) which was on par with T5 (24.2kg/ha). The highest potassium content has recorded in treatment T6 (347 kg/ha) and followed by T5 (345 kg/ha) and lowest in T1 (338kg/ha) as compare to all other treatments. Nitrogen and sulphur analysis of soil samples of different treatments showed that the treatment T6 has highest nitrogen and sulphur contents with 222.8kg/ha and 18.5 kg/ha followed by T5 with 221.2kg/ha and 18.1 kg/ha, respectively. Treatment T1 has recorded lowest nitrogen (206.5kg/ha) and sulphur (12.7 kg/ha) content. Rests of the treatments vary with each other little amount.
