The present study was carried out to evaluate the effects of organic liquid fertilizer (OLFs) fertigation on the growth and fruit quality of hot pepper (Capsicum annuum L.) cv. ‘Nokkwang (Seminis Korea)’. Treatments were given with control (chemical feritilzer), OLF Ⅰ(fowl dropping : fish meal : soybean meal, 2:1:1), OLF Ⅱ(fowl dropping : bone meal : soybean meal, 2:1:1), OLF Ⅲ(fowl dropping : bone meal, 1:1), and OLF Ⅳ(fowl dropping : rice bran : soybean meal, 2:1:1). The composition ratio of OLF based on weight to weight. The pH and EC of OLFs according to different material and compositions ranged from 6.5 to 6.8, and from 2.91 to 3.69dS · m-1, respectively. The C/N ratio was the highest as 5.75 in OLF Ⅳ, and there was no difference among the treatments in C/N ratio of the exception of OLF Ⅳ. In OLF Ⅳ total fruit weight was the highest as 1,558g per plant and total fruit number increased as 23.7% compared to control. The content of capsaicin in the ripened pepper increased with OLF Ⅰ and Ⅱ treatments, and decreased with OLF Ⅲ and Ⅳ treatments compared to control of 662mg ․ kg-1, but the soluble solid content was the highest with OLF Ⅳ treatment as 10.0°Brix.
