Effect of jivamrut on pH, EC, organic carbon and microbial population in soil after harvest of sesame under organic cultivation

Abstract

A field experiment was conducted at Agronomy Instructional Farm, C. P. College of Agriculture, to study the “Response of sesame to jivamrut ” during kharif season of 2020 with Seven treatment combinations comprising, three levels of jivamrut, two time of application of jivamrut and one control (No jivamrut) were evaluated in Randomized block design (factorial concept) with single control and replicated four times. Application of jivamrut, levels of jivamrut and time of application of jivamrut failed to exert any significant influence on available N, P2O5, K2O, pH and EC of soil after harvest of crop. Significantly higher organic carbon was recorded with application of jivamrut at 20 days interval but jivamrut and levels of jivamrut were non-significant. Interaction effect was found not significant for available N, P2O5, K2O, pH, EC and OC of soil after harvest of crop. Significantly higher post-harvest microbial status of Azotobacter and PSB were recorded with application of jivamrut, levels of jivamrut, time of application of jivamrut. Interaction effect was found not significant for post-harvest microbial status of Azotobacter and PSB.
