Ishrath PK, Anil Kumar AS and Nibin PM
Vetiver, a tall tufted perennial grass is being commercially grown for its roots and essential oil. Insufficient availability of quality planting material is one of the major constraints for its area expansion and further use among farmers. The present investigation was conducted to assess the effect of agro-techniques for quality planting material production in vetiver. The four factors tested were planting materials (2), planting systems (2), rooting medium (2) and moisture regimes (2). The experiment was laid out in factorial RBD. The results revealed that, planting of clumps could considerably improve number of tillers and gross returns, while growing of slips significantly enhanced benefit cost ratio. Trough system of planting was found to be economical in vetiver nursery, but planting strips increased crop growth potential. Similarly, additional application of cow dung slurry was effective for higher productivity and profitability in vetiver nursery.
