Description |
Two separate field experiments were conducted to study the effect of root pruning, density of planting and fertilization on establishment, growth and uptake of N, P and K by vetiver on a sandy loam (alfisol) soil at the College Farm, College of Agriculture, Rajendrangar, Hyderabad, during kharif, 1989. The effect of root pruning(O, 5 and 10 cm) before planting and fertilization (with and without N as well as P2o5 each @40 kg ha ) was studied in the first experimene. While, the effect of number of slips {2 and.4 slips/hill) with different spacings (7.5 and 15 cm) and fertilization (with and without N as well as P2o5 each @ 40 kg ha ) was tested in second experiment. Pruniny of roots leaving 10 cm resulted in early and better establishment than either 5 cm root pruning or no root pruning. Growth and nutrient uptake by vetiver was more with 10 cm root pruning either alone or in combination with fertilizers. Planting 4 slips/hill with closer spacing (7.5 cm) resulted in higher percentage of establishment and greater growth · than planting 2 slips/hill with either of the spacings. Fertilization had no significant effect on establishment but it had marked influence on growth of vetiver. Uptake of N, P and K by vetiver was more influenced by the variation in dry matter production due to different treatments rather than that of nutrient composition in both the experiments. Based on the results obtained, pruning of roots leaving 10 cm length and planting closely (7.5 cm) with 4 slips/hill was found to be the best to promote early establishment and growth of vetivr, if it has to serve as an effective vegetative barrier to check ·soil erosion and conserve moisture under rainfed conditions. |
