Abstract
A study was conducted to find out the influence of soil pH on sprouting and survival of one year old Teak (Tectona grandis L. f.) stumps. The stumps were planted in different pH of the soil (8.1, 9.0, 10.2 and 10.5) along with red earth, sand and farmyard manure mixture. Twenty eight days after planting the results revealed that stumps planted in soil with a pH of 8.1 + sand + farmyard manure at 2:1:1 ratio gave more number of sprouts (2.35), leaves (11.10), secondary roots (4.42) and dry matter production (4.11 mg seedling–1) per stumps, which was on par with stumps planted in 10.2 pH soil + sand + farm yard manure mixture. Stumps planted in higher soil pH (10.5) alone inhibited the seedling growth. The species is able to tolerate extreme soil pH of 10.5, when the soil is mixed with sand and farmyard manure at 2:1:1 ratio, in terms of survival, seedling growth and chemical attributes of 180 days old seedlings.
