Productivity and Quality of Three Varieties of Ginger on Many Light Intensity Levels Under Stand of Pine

Abstract

The high demand of medicinal plants with limited agricultural land availability can be solved by the utilization of land under forest canopy through applying agroforestry. This study aim s to assess the effect of different varieties of ginger and different shading intensities of pine ( P inus merkusii ) on the productivity and quality of ginger. The design used was a split plot design consisting of 3 replicates with an area of 100 m 2 for each plot and with spacing of 50 x 50 cm. The main plot is the light intensity treatments, i.e. 50-58% (age class I I), 68-77% (age class I) and 87-92% (poor increment), whereas the sub plot is the varieties of ginger i.e.: small white ginger (emprit), large white ginger (gajah) and red ginger. R esults showed that the light intensity does not significantly affect the percentage of growth, moisture content, volatile oil, fiber, starch and ash. Varieties of ginger significant ly a ffect the percentage of growth, h e igh t growth and weight of rhizome, but do not significantly affect the moisture content, volatile oil, fiber, starch and ash . The a verage yield of each variety of ginger is 5.54 tons/ha , 8.38 tons/ha and 6.7 ton /ha for small white ginger, large white ginger and red ginger , respectively. Agroforestry of ginger plant under pine stand can be done to improve land productivity, especially in poor stand increment .
