Abstract
Investigations were undertaken to evaluate the effect of linseed oil cakes and phosphorus levels on the growth and biomass production of Albizia procera at Tropical Forest Research Institute, Jabalpur, M.P. The growth and biomass production parameters were influenced by the application of linseed oil cakes and single super phosphate alone or in combination with each other. The application of 40 g linseed oil cakes with 30 g ssp per seedling produced highest values for shoot fresh weight, root fresh weight, total fresh and dry weights. Height growth was maximum in combination of 40 g oil cakes with 22.5 g ssp whereas, number of nodules were highest due to application of 30 g oil cakes and 15 g single super phosphate. The easy availability and low investment of linseed oil cakes, it may be preferred over inorganic phosphate fertilizers in order to enhance the growth and biomass of forest trees.
