Efficiency of Vermicompost on Growth and Yield of Water Morning Glory (Ipomoea aquatica Forsk. Var. reptan)

Abstract

The objective of this study aimed to investigate the effect of vermicompost on water morning glory production. The experiment was conducted at Huaymonthong subdistrict, Kamphaengsaen district in Nakhon pathom province. The experimental design was Randomized Complete Block Design (RCBD) with 3 replications. The experiment consisted of 3 treatment as followed: 1) broiler manure 1 kg/m2 2) vermicompost 1 kg/m2 and 3) broiler manure and vermicompost 1 kg/m2. The results showed that there were no significant difference (P 0.05) in plant height, leaf length, leaf width, fresh weight, dry weight and yield weight among treatment. However, chemical composition analysis indicated that broiler manure andvermicompost 1 kg/m2 gave highest chlorophyll a, chlorophyll b and carotenoids (P  0.05), whereas,vermicompost 1 kg/m2
gave the highest ß-carotene (P  0.05).
