Abstract

This research aims to determine: 1) the effect of the comparison of the use of husk charcoal growing media with soil on the growth of pakcoy plants, 2) the effect of the application of liquid organic fertilizer (SO-Kontan Fert) on the growth of pakcoy plants, 3) the effect of a combination of rice husk planting media with soil and POC (SO-Kontan Fert) application to the growth of pakcoy plants. This research was conducted from January to March 2020 at the screen house of Melung Village, Baturraden District, Banyumas Regency, Central Java and the Agronomy and Horticulture Laboratory of the Faculty of Agriculture, Jenderal Soedirman University, with Andisol soil types. The experimental design used was a completely randomized block design (RAKL) with a 2-factor factorial design. The first factor is husk charcoal (M), namely, M0 = without husk charcoal, M1 = soil + husk charcoal (1: 1), M2 = soil (2: 1), soil + husk charcoal (3: 1). The second factor is the concentration of POC SO-Kontan Fert (P), namely, P0 = 0 ml POC SO-Kontan Fert / Lt water, P1 = 5 ml POC SO-Kontan Fert / Lt water, P2 = 10 ml POC SO-Kontan Fert / Lt water, P3 = 15 ml POC SO-Kontan Fert / Lt water. Results of the research showed that giving husk charcoal to pakcoy plant media at a ratio of 3: 1 was able to increase plant height by 47.19 cm and leaf length by 26.13 cm ,. A ratio of 2: 1 can increase leaf greenness by 2.8 units. The application of liquid organic fertilizer (SO-Kontan Fert) with a concentration of 5 ml / l was able to increase the number of leaves by 6.59.

Abstract

This research was conducted to determine the effect of ecoenzyme concentration on the growth of red spinach plants in a hydroponic floating raft system conducted at the Greenhouse of the Faculty of Agriculture, Jenderal Soedirman University, Purwokerto. Ecoenzyme application treatment, namely: 0 ppm; 1000 ppm; 2000 ppm; and 3000 ppm with 6 replications arranged based on Completely Randomized Block Design (RAKL). Observations made consisted of: plant height, number of leaves, root length, leaf area, and root volume. The F test (ANOVA) at an error level of 5% was carried out to find out whether the treatment affected the observed variables. The LSD test at an error level of 5% is carried out if the F test is real. The results showed that the plant height of red spinach 2 MST was not affected by differences in ecoenzyme concentrations in the nutrient media; Plant height at 4 WAP with 1000 ppm ecoenzyme treatment was the highest and plant height at 6 WAP with 0 ppm and 1000 ppm ecoenzyme treatment was not different, while plant height growth with 2000 ppm and 3000 ppm treatment was lower. The number of leaves at 2 WAP, 4 WAP and 6 WAP, root length, leaf area, and root volume in all treatments of ecoenzyme concentration application showed no difference.
