Lemongrass

Preamble

Lemongrass, is a perennial herb widely cultivated in the tropics and subtropics. The reported adaptation zone for lemongrass is 18 to 29^oC with an annual precipitation of 0.7 to 4.1 meters with a soil pH of 5.0 to 5.8. Since the plants rarely flower or set seed, propagation is by root or plant division. The plants are harvested mechanically or manually about four times each year with the productive life span between four and eight years. In the present experiment, the crop was harvested after 90 days of planting.
