Evaluation of medicinal and aromatic crops under teak based agroforestry system.
The experiment was laid out in randomized block design. In each plot, there were two teak plants spaced at 2.4 m apart in the middle of the plot, medicinal and aromatic plants were grown on either side of the teak rows. The observations were recorded on growth parameter of medicinal and aromatic plants at three stages i.e., 2 months, 4 months and at harvest stage. In the present investigation, among different medicinal and aromatic crops grown with teak, significantly higher herbage yield was obtained in aloe than in other crops. There was marginal reduction in herbage yield of all the medicinal and aromatic crops (except coleus). The highest collar diameter was recorded in aloe and lemongrass. There was significantly higher number of branches/tillers was observed in lemongrass, whereas it was, least in aloe at harvest. The higher growth rate in aloe, lemongrass and coleus resulted in higher fresh and dry weight in shoot and root with subsequent increase in total fresh and dry weight per plant. However, compared to their respective sole crops, total dry weight per plant was reduced in aloe and lemongrass; on the contrary, there was increase in total dry weight per plant of coleus. Thus, among medicinal and aromatic plants grown with teak, aloe, lemongrass and coleus are found to superior in terms of herbage yield.
