ABSTRACT
An investigation was undertaken on permanent plot after fourteen years of rice cropping on Vertisol resulted that the continuous use of farm yard manure, blue green algae and green manure in conjunction with fertilizers increases the physical properties of soil like infiltration rate, hydraulic conductivity, mean weight diameter and percent water stable aggregates as well as rice yield. The 100% NPK+FYM resulted highest infiltration rate (8 mm/hr), hydraulic conductivity (1.11 cm/hr) and percent water stable aggregates (48.56). Mean weight diameter highest in 50% NPK+GM (2.093 mm) followed by 100% NPK+FYM (2.051 mm) and lowest in control (1.302 mm). The grain and straw yield of rice were higher in where 150% RDF (5065 and 7075 Kg/ha) followed by 100% NPK + FYM (4855 and 6565 Kg/ha). The results suggest that integrated use of inorganic in combination with organic facilitates optimum soil physical environment for higher crop productivity. The Change in Nutrient balances higher values were recorded in inorganic treatments compare to the organic treatments due to increasing rates of fertilizer application increased nutrient balance.
Keywords: Permanent plot, water stable aggregates, infiltration rate, hydraulic conductivity, mean weight diameter.
