Get ready the pits measuring 45cm x 45cm x 45cm and keeping a space of 2m x 2m, 3m x 3m, or 4m x 4m prior to rainy season, given that seedlings should be planted during the rainy season. Thus, T. grandis, C. odorata and C. dactylon will be priority plants to be managed in PNR, especially in Cikamal grassland. Analyses of molecular variance (AMOVA) detected the highest genetic variation within populations. Commercial illegal trade is the largest threat to important timbers in India and industrialized countries. The whole objective of teak plantation project is production of first-rate timber in plants with desired growth rate, which maximizes yield. This is one of the most valuable and high-priced timber crops in India. Teak timber, from Rajulmadugu of Andhra Pradesh has pink coloured. Moderate to good flowering and fruiting.

About 70,000 ha of plantations, indigenous forests of teak (Hedegart, 1976), and teak, 6.5 to 7.5 (Kulkarni, 1951; Tewari, 1992). At the end of germination study (120 DAS), maximum germination was observed in Sirsi population (13.1%), followed by Kiravathi (11.10%). The functional confirmation of the insecticidal activity of WsMBP1 established its potential as a novel gene resource for future transformation studies in developing teak genotypes tolerant to its leaf defoliator, H. puera. The altitude of the area varies from 200 to 250 meters above mean sea level. It also occurs, hot season and soil pH 5.0 to 8.0. If you are planning for commercial teak plantation, you must be aware of seed rate of teakwood, the yield of teakwood, planting methods, care along with teak harvesting techniques. The studies on diversity of teak populations showed that teak is an out crossing species with major portion of diversity present within the populations. Several aspects like phenology, reproductive biology, fruit characteristics, silvicultural practices for cultivation, pest and diseases problems, production of improved planting stock, harvesting and marketing, wood properties and future tree improvement strategy to enhance productivity have been discussed in this paper. About 700 plus trees of teak have been selected. The experimental data were tested using Langmuir, Freundlich and Temkin isotherm models, and the data were best followed by Langmuir one. Harvest time. Present investigation explores the possible reusability of synthetically contaminated wastewater containing crystal violet (CV) organic dye using Tectona grandis sawdust (TGSD) waste as a very low-cost adsorbent.
