 ABSTRACT

The present study conducted under All India Coordinated Research Project (AICRP) on long-term fertilizer experiment was aimed on the effect of inorganic fertilizers, with or without organic manure on gravimetric and volumetric moisture content, total porosity, nutrient content in grain and straw, nutrient uptake in grain and straw and yield after 14 years of rice-wheat sequence during 2013-2014. The treatments selected for the study were control, 50% NPK, 100% NPK, 150% NPK, 100% NPK + Zn, 100% NP, 100% N, 100% NPK+FYM, 50% NPK + BGA and 50% NPK + GM. The investigations revealed that crop yields were lowest in the control where neither fertilizers nor manures were applied for the last fourteen years and highest in 150% NPK. The total porosity, gravimetric and volumetric moisture content of the soil is higher values recorded in 100% NPK + FYM, 50% NPK + BGA and 50% NPK + GM treatments compare to other treatments. The total uptake of nutrients is recorded better values in the integrated nutrient treatments as compare to inorganic treatments and control. Integrated use of organics and inorganics has sustained the crop yields and improves the soil health.

Key words: Rice, Cropping system, Moisture content, Porosity, Nutrient content, Nutrient uptake, Soil health
