Abstract

Ginger is a popular rhizome propagated crop and economically important for Malaysia due to increasing demand of ginger as a spice, flavouring agent and herbal remedy. However, locally produced ginger might not be able to cope with the increasing demand. There are many fertilizers available in the market but the effects of these fertilizers on the ginger plant growth are not clear. Besides that, hydroponic system can effectively increase the productivity of the crop and overcome the issues of availability of land. In this study, experiments were conducted to study the effects of different types of fertilizers (water soluble NPK red with ratio of 14:10:32, modified Hoagland solution and vermicompost) on growth, yield, chlorophyll contents, photosynthesis rate and biochemical of hydroponically planted ginger. Ginger plants were cultivated using cocopeat. Various fertilizers had significantly affected plant height, yield, chlorophyll contents, photosynthesis rate (p < 0.05). Plants treated with NPK red had grown well in terms of number of leaves, chlorophyll contents and photosynthesis rate as well as the highest plant height (76.33 cm ± 9.61) and fresh weight of rhizome (449.67 g ± 363.71). The results also showed that pH, moisture and electrical conductivity of cocopeat in all treatments were slightly affected by application of fertilizers. TPC in control ginger rhizomes (75.12 mg/ 5 g DW) was higher and 6-gingerol (17.62 mg/ 5 g DW) in modified Hoagland solution treated ginger rhizomes was higher. In conclusion, NPK red fertilizer is the best with suitable nutrient concentration and had the least influence on cocopeat pH, moisture and electrical conductivity for ginger planted in cocopeat.
