EFFECT OF POULTRY MANURE AND ETHEPHON ON GROWTH, YIELD, AND QUALITY OF CAYENNE PEPPER (CAPSICUM FRUTESCENS L.) ‘RATUNI UNPAD’
The production of ‘Ratuni UNPAD’ cayenne pepper can be increasedusing organic chicken manure. However, the application of ethephon isneeded during fertilization due to the significantly slow flow er initiation.Therefore, this study aims to determine the interaction betweenchicken manure and ethephon on the growth, yield, and quality of the‘Ratuni UNPAD’ cayenne pepper. Planting is carried out 829 metersabove sea level (masl), and a factorial randomized block experimentaldesign comprises 2 factors with 3 replications. The first factor is thedose of chicken manure (10, 20, 30, and 40 t/ha), while the second isthe ethephon concentration (0, 500, 1000, and 1500 ppm). The resultsshowed no interaction between poultry manure and ethephon on thegrowth, yield, and quality of the ‘Ratuni UNPAD’ cayenne pepper.According to the doses of chicken manure, 40 t/ha significantly affectsthe flower initiation, fruit number, weight, length, anddiameter, as wellas capsaicin and dihydrocapsaicin. The 30 t/ha shows the highestvalue for the number of leaves and productive branches, while 20tons dose/ha influences flavonoids, phenolics, and total carotenoids.The ethephon concentration of 1500 ppm significantly affects theflower initiation, fruit length, diameter, capsaicin, and dihydrocapsaicin.
