Exotic pine trials in uttar pradesh india

, : Exotic pine trials in uttar pradesh india. Indian Forester 108(2): 131-143

Trials of exotic pines were started here from 1960-61 onwards. Field trials laid at various places and at different elevations have indicated that Pinus patula, P. greggii, P. pseudostrobus and P. montezumae when planted in the deep moist soils at an elevation ranging between 1800-2000 m, grow faster than local chir pine in early stage up to 15 yr age. P. elliottii and P. taeda come up even on skeleton soils between 1200-1500 m but survival is poor. In the nurseries seed is sown on pure sand and pricking is generally done 15-20 days after germination. Mycorrhizal soil is added to the potting mixture and also after about a wk in bagged plants. Spraying of 0.25% to 0.33% of Agromine or 1-2 g of Sufla or D.A.P. and 2-3 g of superphosphate increases height growth of seedlings significantly. In the field plantings plants of 20-25 cm height are used. Pit size 45 cm3 has given the best results and is adopted for field plantations. Spacing is kept 2 m .times. 2 m or 3 m .times. 3 m. Most of the exotic pines start bearing cones at 5-6 yr and produce mature seeds after 9-10 yr. The viability of seed varies from 25-30% in case of P. patula and P. greggii. Micro-tapping done in very limited number of plants of 13 spp. indicated that P. elliottii gives satisfactory resin yield while in P. patula and P. greggi yield is poor. In nurseries seedlings are sometimes killed by Cercospora, Fusarium and other fungi. In the field an attack of Diplodia pinea was noticed at several places. This results in die-back and top drying of plants. In several cases plants become bushy. Mild incidence of Lophodermium was also noticed. Localized damage to the plants from Chafer grub, bag worms and termites was also noticed. Though the field plantations of exotic pines are very recent and stage of harvesting has not yet been reached, their potential use can be for long fibered pulp, for transmission poles after proper prophylactic treatment and in manufacture of paper by thermo-mechanical process.
