    Influence of Containers, Potting Mixtures in Nursery Spacing and Nutrient Management in Early Field Establishment of Salacia chinensis
    (UAS, Dharwad, 2013) Somashekar J.; K.S. Channabasappa
    Salacia chinensis is an important medicinal plant found throughout India including Andaman and Nicobar Islands. This plant having a greater importance in modern medicine which leads to commercial cultivation. The over exploitation of this plant in forest which leads to depletion of population in forest. In view of this, an experiment was undertaken during 2011-12. Raising good quality seedlings at nursery stage is a very important aspect for success of any plantation programme. Spacing and integrated nutrient management are the two important factors which influence the growth and productivity of plants. A nursery experiment was conducted at College of Forestry, Sirsi, Uttara Kannada district of Karnataka. Geographically nursery is situated at 140361 N latitude and 750531 E longitude and an altitude of 619 m MSL. Mean annual rainfall is 2657 mm, most of which is received between June to October. Temperature varies from 9.50C to 350 C. The experiment was laid out in factorial completely randomized design (Factorial CRD) with three replications. The present experiment revealed that, root trainers and poly bags did not show significant differences in plant growth of Salacia chinensis. The data revealed that the effect of different potting mixtures had significant effect on plant growth. Maximum plant growth was recorded in 2: 1: 1 with 1 g DAP at all stages of seedling growth followed by 2: 1: 1 with 5 g VAM. At 12 MAT, 2:1:1 with 1 g DAP recorded maximum growth parameters (12.66 cm plant height, 4.02 mm collar diameter, 20.8 number of leaves) fresh and dry weight of leaves, root and stem in gram (9.16 and 1.83), (7.27 and 1.45), (11.24 and 2.70) followed by 2: 1: 1 with 5 g VAM. The field experiment was conducted at Agricultural Research Station, Malagi of Mundgod, Uttara Kannada District of Karnataka. The place is situated at 140381 N latitude and 750001 E longitude at an altitude of 490 m above mean sea level (MSL). The experiment was laid out in split plot design with the spacing 0.5 × 0.5, 0.5 × 1 and 1 × 1 m in main plot and fertilizer levels in subplot. Planting was taken up with one year old Salacia chinensis seedlings. Spacing and nutrient levels recorded significant difference in plant growth among treatments. Wider spacing (1 x 1 m) along with 10 tons FYM + 50:100:50 NPK kg/ha recorded significantly maximum plant growth over other treatments (plant height 43.28 cm, collar diameter 7.27 mm, number of leaves 20.2) followed by 1 x 0.5 m with 10 tons FYM + 50:50:50 NPK kg/ha (plant height 42.08 cm, collar diameter 7.16 mm, number of leaves 20.0). Significantly lower (plant height 21. 96 cm, collar diameter 5.79 mm, number of leaves 17.6) recorded in 0.5 x 0.5 m with control.
