Abstract
The aim of this study was to evaluate the effect of 3 environment- friendly farming materials on the growth of pepper and tomato seedlings under low level of solar radiation. The pepper and tomato seedlings were separately grown on commercial substrate and non-fertilizer substrate under 30% shading condition, respectively. The microbe-, enzyme-, and amino acid-supplements were used for the foliar application to the seedlings. The application of enzyme- and amino acid-supplements significantly enhanced the growth of tomato and pepper seedlings grown on non-fertilizer substrate, while there was no significant effect on the seedlings grown on commercial substrate. The foliar application of enzyme- and amino acid-supplements reduced the days to flowering by 3 to 4 days and lowered the node order of fruit set in tomato plants grown on non-fertilizer substrate. The results showed that the enzyme- and amino acid-supplements could enhance the seedling growth and lower the node order of fruit set under limited nutritional conditions.
