PENGARUH PUPUK ORGANIK PADAT DAN BERBAGAI KONSENTRASI PUPUK BIO-ORGANIK CAIR TERHADAP PERTUMBUHAN DAN HASIL TANAMAN PAKCOY (Brassica rapa L.)

Abstract

Pakcoy (Brassica rapa L.) is one type of vegetable that is widely favored by the public because      it has a high nutritional content, the price tends to be cheap and requires a short harvest time so that it has very good prospects. This study aims to determine the effect of giving cow dung bokashi fertilizer and various concentrations of Herbafarm Liquid Bio-Organic fertilizer on the growth and yield of pakcoy plants. This research was conducted in Oloboju village, Sigi Biromaru sub-district, Sigi Regency. From October 2022 to January 2023. This study used a 2-factor Randomized Block Design (RAK). The first factor is the dose of cow bokashi fertilizer, which consists of 2 levels, namely 0 t / ha and 20 t / ha. The second factor of the dosage of Herbafarm Liquid Bio-organic Fertilizer is 0 ml/l of water, 5 ml/l of water, 10 ml/l of water, 15 ml/l of water, and 20 ml/l of water, thus there are 10 combinations of treatments repeated 3 times so that there are 30 beds and each treatment consists of 50 plant units. The data obtained were analyzed by analysis of diversity (ANOVA), if there is an influential treatment, it will be continued with the Honestly Significant Difference (HSD) test at a level of 5%. The results of the study showed the interaction between 20 tons/ha of Cow Manure Bokashi (P1) and the provision of 20 ml/liter of Herbafarm Liquid Bio-organic Fertilizer (K4) on the number of leaves at the age of 25 HST. The provision of 20 tons/ha of Cow Manure Bokashi Fertilizer (P1) had a significant effect on the parameters of fresh weight of the canopy, fresh weight of the roots, greenness of the leaves, and total leaf area. The administration of Herbafarm Liquid Bio-organic Fertilizer 20 ml/liter of water (K4) had a significant effect on the fresh weight of the canopy, fresh weight of the roots and total leaf area, but had no effect on several variables.
