Influence of Organic Manures Alone and in Coimbination with Inorganics on Properties of a Black Soil and Jowar Yield,

Studies to evaluate the efficacy of organic sources of manures as compared to chemical fertilizers in a black soil revealed that the application of organic sources at different levels in combination with inorganic fertilizers had significantly increased the grain and straw yield of CSH 5 sorghum. The physical properties of the soil viz. bulk density, hydraulic conductivity and total pornsity and also the nutrient contents were found to have impraved. The uptake of the nutriants by the crop was found increased due to the addition of organic manures with fertilizers as compared to control and inorganic fertilizers alone.
