EFFECT OF DIFFERENT SOIL MIXTURES AND FERTILIZERS ON THE GROWTH OF DALBERGIA SISSOO ROXB. SEEDLINGS

摘要

The present study was undertaken to identify best soil mixture and fertilizer doses for raising quality seedlings of Dalbergia sissoo Roxb, in nursery. Among all the potting mixtures, i.e., soil, sand and FYM in 1:2:2 and 1:2:1 ratios indicated higher growth, dry weight and quality index of seedlings. It was further observed that seedling growth increased on increasing FYM in all the combinations of potting mixture, while increase of sand in potting mixture beyond 1:2:2 ratio of soil, sand and FYM was not beneficial for the growth of seedlings. The application of 100 mgurea and 25 mg SSP in soil mixture showed maximum growth and dry weight of seedlings. Root nodulation was, however, inhibited by the application of these fertilizers. The response breadth was wider for all the traits in both these experiments. However, it was comparatively higher under different soil mixtures than for fertilizer doses.
