GROWTH AND YIELD RESPONSES OF GINGER (Zingiber officinale Rosc.) TO SOLID ORGANIC FERTILIZER AND COMPOSITION OF PLANTING MEDIA

Abstract

The objective of the research was to study the response of ginger (Zingiber officinale Rosc.) grown in baskets system, in terms of growth and yield to the application of solid organic fertilizer and composition of planting media. The research used Factorial Randomized Complete Block Design with 2 factors and 4 replications. The first factor was solid organic fertilizer which consisted of 2 treatments: without and with solid organic fertilizer. The second one was composition of planting media with 4 treatments which consisted of compost: sand=2:1; compost: paddy chaff= 2:1, top soil: cow manure: sand= 3:1:1 and top soil: manure: paddy chaff= 3:1:1. The results showed that solid organic fertilizers had promoting effects on ginger growth and yield as shown by increasing bud number and rhizome weight per plant. The mixture of top soil: manure:sand/paddy chaff of 3:1:1 was the best planting medium for zinger growth
