Effect of Different Levels of N, P, K on the Growth of <I>Robinia pseudacacia</I> Linn. Seedlings

Abstract

The experiment was conducted to study the effect of different levels of N, P and K on the growth of Robinia pseudacacia Linn. Seedlings under nursery corditions during 1987-88. The effect of different levels of N, P and K on shoot height, root length, and coller diameter was found non-significant. Response to cliper growth was maximum at (N₃, P₃, (N₃₇₆ P₂₅₀ mg plant1), whereas N₃, P₂, K₂, (N₃₇₅ P₂₅₀ K₂₅₀ mg plant^-1) gave maximum response to total biomass.
