Refinement of Container Type and Potting Medium Mixture for Production of Quality Seedlings in Chilgoza Pine (<I>Pinus Gerardiana</I> Wall.)

Abstract

Pinus gerardiana Wall. (Chilgoza pine) is an important species of dry temperate zone of North-West Himalaya valued chiefly for its edible nuts. Study was conducted to determine the effect of container types viz. root trainer 275 cc (k₁), root trainer 300 cc (k₂), bottom hole polybabgs (BHP) - 23 x10cm ((k₃), and bottom hole polybabgs (BHP) - 16 x10cm ((k₄), and growing medium chilgoza forest soil (CFS) (M₁), CFS+Sand+moss - 1:1:1 (M₂) and CFS+Sand+moss+FYM - 1:1:1:1 (M₃) on seedling growth parameters under nursery. Use of BHP - 23×10 cm filled with CFS+sand+mass+FYM proved best for most of the seedling growth parameters under nurseryy condition.
