ABSTRACT
The influence of organic manure on the soil properties and beneficial soil microorganisms in the mulberry garden was studied. Data on soil characters, leaf quality traits and microbial population was recorded in inorganic (T0) and organic manure (T1) plots. The results revealed that soil pH decreased considerably whereas, macronutrients (OC, P & K) and micronutrients (Mn, Fe, Cu, and Zn) increased significantly in T1 as compared to T0 plot. Microbial population slightly improved in T1 compared to T0. Leaf quality traits viz., leaf moisture, available nitrogen, phosphorus and potassium showed significant difference between T0 and T1. Among quantitative traits, leaf yield/ plant and its contributing traits showed no significant difference between T0 and T1. Application of organic manure enhanced the soil fertility and microbial status in the soil. It is concluded from the study that, total avoidance of chemical fertilizer can be substituted by the application of different sources of organic manures for sustainable mulberry crop production.
Key words :
