Abstract: Study on the Effect of fly ash and organic manure on growth of tree borne oilseed Simarouba gluca seedling and properties of potting mixture experiment was conducted at Agro Forestry nursery at MARS, Dharwad Karnataka during 2013-2014. Fly ash based pot mixture containing organics viz., FYM and VC are mixed in 9 different ratios combinations on w/w basis with and without soil including two controls. The data on bulk density, water holding capacity and organic carbon content of fly ash based mixture in different treatment combination differed significantly. And the values are 0.61 Mg m-3, 69.34 per cent and 15.29 g kg-1 respectively in pot mixture containing fly ash, FYM/VC and soil in different proportions. The growth parameters viz., plant height, number of branches, root length and total dry biomass improved significantly and the average nursery seedling height was enhanced to 120 per cent in the treatment receiving fly ash, FYM/VC in 1:2, 1:3 and 1:2:1, 1:3:1 with soil over the control and other treatments. The study indicates that the Simarouba gluca had high potential for nutrient uptake due to high biomass production during seedling growth besides fast growth. There was increased uptake of N, P, K, Ca, Mg, S and micro nutrients in all the treatment combination receiving fly ash based pot mixture containing organics with or without soil. Variations in the concentration of nutrient elements in the plants and uptake by the leaves and stem of nursery seedlings was observed for major N.P.K nutrients which varied as N=K>P, secondary nutrients varied as Ca>S>Mg and micro nutrients varied as Fe>Mn>Zn>Cu. However, there was marginal variation in the physic-chemical properties of pot mixture over a period of 150 days after the growth of nursery seedlings. Incorporation of fly ash in pot mixture with organic substrates resulted in a concentration dependent improvement in dehydrogenase activity in pot mixture. Hence, fly ash can promote microbial activity when mixed with organic substrate which enhanced its benefits, which assumes importance owing to eco friendly disposal of fly ash. The results of the study indicated that fly ash can be used as an alternative to soil for pot mixture for raising of nursery seedlings.
