Groundnut is the mostly grown commercial oilseed for millions of small scale farmers in the semi-arid topics and under rainfed conditions in Andhra Pradesh. The productivity of groundnut grown under rainfed situation is declining from the actual production of 1.23 m t to the lowest yield of 0.8t ha-1 in India, under the crop area coverage of 1.38 m ha. The reasons behind the low productivity in India is mainly due to poor soil fertility, deterioration of soil physical properties, monocropping, low rainfall and frequent occurrence of dry spells, imbalanced use of plant nutrients and sub-optimal addition of organic and inorganic fertilizers to soil. Application of manures and fertilizers change the physical, chemical and biological properties of soil which in turn affects the availability of soil nutrients. Long-term manure and fertilizers experiment provides valuable information on impact of continuous use of fertilizers with varying combination of organics and inorganics on soil physical, chemical properties and crop productivity and became good platform for monitoring the changes in soil physical properties and productivity. Observed effect of Long term application of inorganic fertilizer along with organic fertilizer changes physical properties like infiltration rate, cumulative infiltration and aggregate MWD and productivity. The literatures reported below regarding the long-term effect of application of manure and fertilizers on Soil physical properties and yield of rainfed groundnut.
