Abstract
Deteriorating soil fertility and concomitant decline in crop yield are major concerns to feed the growing population. A field experiment was conducted in 2019-2020 in the experimental farm of vegetable block at Organic Farm Research Centre (OFRC), Chatha at Sher-e-Kashmir University of Agricultural Sciences & Technology, Jammu (J&K) to test the hypothesis that application of biochar and organic manures improves physicochemical properties, growth and yield of radish. The treatments consisted of two levels of biochar (0tha-1, 3tha-1) and four levels of organic manures (Control, FYM, VC, FYM+VC) in factorial randomized block design. Soil physicochemical properties as moisture %, aggregate stability, infiltration rate, soil compaction, macro-aggregate associated organic carbon, available nitrogen, available phosphorus were improved by the application of biochar and manures. Water use efficiency significantly increased with the application of 3tha-1 biochar (254.92 kgha-1mm-1) as compared to no biochar. Similarly, addition of organic manures increased the water use efficiency and the highest increase was observed in M3 (294.65 kgha-1mm-1). Plant growth parameters like root length and yield showed a positive correlation with soil nutrient status (NPK), EC, OC, IR, macro aggregate stability and WUE and a negative correlation with BD, PR and micro aggregate stability. Radish yield was significantly improved in all the treatments over control. The highest crop yield (225 qha-1) and maximum benefit cost ratio of 1.60 was recorded in combination of 3tha-1 biochar and 50% N through FYM+50% N through VC.
