| Abstract:
Five types of organic substrates were evaluated for basket (45 x 55 x 24 cm) culture of sweet pepper in plastic house. The substrates were: CDP (chicken dung compost substrate), SRC (sugarcane residue compost substrate), TNM (Taoki no.3 substrate), CDB (cattle dung compost substrate) and HDP (hog dung compost substrate). Plants grown in CDP, SRC, and HDP had higher marketable fruit yield compared to the control, bag culture. Meanwhile, plants grown in SRC could obtain the highest marketable fruit yield (66,536 kg/ha). Hence, SRC was used as substrate for basket culture of sweet pepper to compare the training methods of single stem, double stems and no training at the densities of 4 or 6 plants in each basket in the following experiment. The highest marketable fruit yield (49,952 kg/ha) was achieved by double-stem training at a density of 6 plants per basket. Plants trained to double stems at a density of 4 plants per basket resulted in higher proportion of large sized fruits. The matured period distributed more evenly in trained plants than in non-trained plants. Overall, under subtropical condition in Taiwan, sweet pepper grown in basket with SRC substrates could gain higher yield than bag culture in plastic house. Growing sweet pepper with double-stem training method at a density of 6 plants per basket was recommended. | |
