1995

Mixtures of soil and compost, soil and manure, soil and rice ash, soil and rice husk at ratio 1:1, 1:2, 2:1 by volume and soil were used as growing media for bell pepper seedling (California Wonder), at Tropical Vegetable Research Center (TVRC), Kasetsart University, Kamphaengsaen Campus, Nakhon Pathom province, from July 1992 to December 1993. Soil and compost at the ratio 1:2 by volume showed plant better in height, canopy, leaf number, leaf area, leaf dry weight and stem dry weight. The highest root dry weight was obtained from pepper grown in soil and rice ash mixture at the ratio 1:1. Effect of 9 ratios of N:P2O5:K2O fertilizer on growth of bell pepper seedling was co-studied with 2 types of growing media using the open system of watering. When soil and compost (1:2) was use as media, the highest plant canopy, leaf dry weight and root dry weight were obtained in the treatment ratio of 2:1:2 of N:P2O5:K2O, while the highest plant and the most leaf area were obtained from the ratio of 1:2:1 of N:P2O5:K2O. When soil and rice ash (1:1) was use as a growing media with 2:2:1 fertilizer ratio, the seedling was found to have highest number of leaves and root dry weight. After transplanting into the experimental field, soil and compost (1:2) media allowed more survival seedling than the seedling from mixture of soil and rice ash at the same ratio of fertilizer.
