Abstract

Pakcoy (Brassica chinensis L.) is a vegetable from the Brassicaceae family. Pakcoy is a short-lived plant. Pakcoy contains fat, protein, Fe, Ca, P, Vitamins A, B, C, E, and K, with that pakcoy is very good for health and has prospects for high economic value. The first factor affecting the decline in pakcoy production is soil fertility. The continuous use of land with chemical fertilizers results in a decrease in biological, chemical and physical soil fertility, one of the efforts to overcome this problem is to improve cultivation techniques through fertilization. This study aims to determine the growth response of the pakcoy plant by administering liquid organic fertilizer from mushroom baglog waste and watermelon rinds. This study used a factorial complete randomized design with 2 factors, namely the interval of watering of liquid organic fertilizer and the volume of organic fertilizer dilution concentration and used quantitative descriptive analysis with the Two Way ANOVA test. The purpose of this study was to determine the growth response of the pakcoy plant to the application of liquid organic fertilizer from mushroom baglog waste and watermelon rinds. The results of this study indicated that the TIV3 treatment (watering interval once every 3 days with a volume of 30% dilution concentration) gave a response to plant height with an average of 18.05 cm, number of leaves with an average of 6 leaves, and an average fresh weight of 11.50 g.

Abstract

Cayenne pepper is one of the most popular horticultural crops, therefore fertilization can be used to increase the growth of chili plants. This research was conducted to determine the effect of the POC combination of tea dregs and coconut coir on the growth of cayenne pepper. The study was conducted using an experimental method using a completely randomized design (CRD) factorial pattern, namely POC concentration factor P0 (without giving POC), P1 (100 ml POC tea dregs and coconut coir + 900 ml water), P2 (200 POC tea dregs and coconut coir ml + 800 ml water), P3 (POC tea dregs and coconut coir 300 ml + 700 ml water) and time intervals H1 (3 days), H2 (6 days). Observational data were analyzed by ANOVA test with 5% confidence level. The parameters measured were plant height, number of leaves and wet weight. The best growth of cayenne pepper plants was in the P3H2 treatment (300 ml POC concentration + 700 ml water and 6 days interval) with an average plant height of 24.5 cm, 8 leaves and 14.5 g fresh weight.
