Effect of organic source of fertilizers and soil textures on growth and nutrient uptake in Dalbergia sissoo Roxb.

Abstract

The study aimed at exploring the use of organic materials viz., rice husk ash, paddy straw based biodigester slurry and farmyard manure and to see the effect of soil textures on plant growth, biomass production and nutrient uptake in Dalbergia sissoo. The study comprised of  nursery experiment established in factorial complete randomized design with three replications. The experiment comprised of twenty-one treatment combinations of three soil textures (sandy loam, loamy sand and clay loam), six amendments (FYM 50%, FYM 33%, bio digester slurry 50%, bio digester slurry 33%, rice husk ash 50% and rice husk ash 33%) and control (only soil). The seedlings produced in mixture of sandy loam and bio digester slurry (2:1) resulted in maximum root length (160.33 cm), number of nodules (25.33), number of leaves (46.33), biomass production and nutrients uptake.
