Studies on the Growth Performance of Some Green Manure Leguminous Crops and their Residual Effect on the Organic Matter and Available Nutrients in Eroded Teak Nursery Soils of Nainpur (M.P.)

A field experiment was conducted on eroded teak nursery soil of Nainpur (M.P.) to study the growth performance of some green manure leguminous crops and their residual effect on organic matter and available nutrients. The order of obtaining maximum dry matter yield/plant was Arahar> Chakora> Soybean> Urd> Moong> Sannhemp. The average number of nodules/plant was maximum in Moong and Sannhemp at the intervals of 30 days and in Soybean and Arahar at 60 days interval. Number of nodules in all the leguminous crops decreased as the crop approached to maturity. The green manuring added the organic matter in surface soil treated with moong, soybean and sannhemp and increased the availability of soil nitrogen and phosphorus in surface and sub-surface layers in all the treatments. No appreciable changes in available potassium has been noticed in surface soils but a significant decrease was observed in sub-surface layer in all the treatments over control.
