Abstract

Tomato production in West Java has decreased in 2021-2023 due to suboptimal cultivation practices, especially in the continuous use of chemical fertilizers with excessive doses. The use of liquid organic fertilizers is one potential solution. The research method used is an experimental method, using a single factor Randomized Block Design (RAK) consisting of 9 treatments and repeated 3 times, with treatments consisting of A (NPK 300 kg + POC 0 ml), B (NPK 240 kg + POC 2 ml), C (NPK 240 kg + POC 4 ml), D (NPK 240 kg + POC 6 ml), E (NPK 240 kg + POC 8 ml), F (NPK 180 kg + POC 2 ml), G (NPK 180 kg + POC 4 ml), H (NPK 180 kg + POC 6 ml), I (NPK 180 kg + POC 8 ml). The observation data were analyzed by analysis of variance and further tested with the Duncan Multiple Range Test (DMRT) at a level of 5%. The results of the F test showed that there was a significant effect of the combination of NPK fertilizer doses and the concentration of liquid organic fertilizer from fruit waste on the growth and yield of tomato plants (Solanum lycopersium) of the Gustavi F1 variety. The DMRT test showed that treatment E (NPK 240 kg + POC 8 ml) gave the highest results on the average parameters of plant height 78.187 cm, Number of leaves 22.6 stalks, Stem diameter 9.387 mm, Fruit weight per grain 51.635 g, Number of fruits per plant 15.333 grains, Fruit weight per plant 792.667 g, Fruit sweetness level (Brix) 7.667. Keywords: NPK fertilizer, liquid organic fertilizer, tomato

Abstract

Obtaining soybeans with good yields can utilize chicken manure fertilizer and liquid organic fertilizer from water hyacinth. This study aims to determine the effectiveness of chicken manure fertilizer and liquid organic fertilizer from water hyacinth on soybean plant production. The research method used a Factorial Randomized Block Design (RBD) consisting of 2 factors with 16 treatment combinations and 2 blocks. The factors studied were chicken manure fertilizer treatment (A) consisting of 4 levels: 0, 2, 3, and 3 kg/plot. The liquid organic fertilizer from water hyacinth (E) consisted of 4 levels: 0, 300, 400, and 500 ml/liter of water per plot. The parameters observed were: number of pods per plot (pods), pod weight per sample (g), and weight of 100 dry seeds (g). The research results indicate that the effectiveness of chicken manure fertilizer on soybean plant production has a very significant effect on the number of pods per plot (pods), pod weight per sample (g), and 100 dry seed weight (g). The best treatment was the application of chicken manure fertilizer at 3 kg/plot. Keywords: influential, production, treatment

Abstract

This study aimed to evaluate the effect of compost and urea application on the growth of cucumber (Cucumis sativus L.). The experiment was conducted at the experimental field of the Faculty of Agriculture, Universitas Pembinaan Masyarakat Indonesia (UPMI), using a Randomized Block Design (RBD) with four treatments of compost and urea combinations, namely K0U0 (0 kg compost + 0 g urea), K1U1 (1 kg compost + 10 g urea), K2U2 (2 kg compost + 20 g urea), and K3U3 (3 kg compost + 30 g urea), each replicated three times. The observed parameters were plant height and number of leaves at 2, 4, 6, and 8 weeks after planting (WAP). Data were analyzed using analysis of variance (ANOVA) followed by Duncan’s Multiple Range Test (DMRT) at a 5% significance level. The results indicated that compost and urea treatments, either applied individually or in combination, did not significantly affect plant height and leaf number of cucumber at all observation periods based on ANOVA and DMRT analysis. However, there was a tendency of increased average plant height and leaf number under the highest combined treatment (K3U3). This suggests that balanced fertilization with compost and urea has the potential to support cucumber vegetative growth, although under the present experimental conditions, the effect was not statistically significant. Keywords: compost, urea, growth, cucumber

Abstract

This study aimed to determine the effect of applying Jadam Microbial Solution (JMS) and liquid NPK fertilizer, both factorially and in combination, on the growth of mustard greens (Brassica juncea L.). The experiment was carried out using a factorial Randomized Block Design (RBD) consisting of two factors. The first factor was JMS application with four levels (J0 = 0 ml/l water, J1 = 100 ml/l water, J2 = 200 ml/l water, J3 = 300 ml/l water), and the second factor was liquid NPK fertilizer with four levels (N0 = 0 ml/l water, N1 = 10 ml/l water, N2 = 15 ml/l water, N3 = 20 ml/l water). Each treatment combination was repeated three times, resulting in 16 treatment combinations. The results showed that JMS application had a significant effect on plant height and number of leaves at all observation times (7, 14, and 21 days after planting/DAP), indicating improved vegetative growth and yield. Liquid NPK fertilizer application also significantly affected plant height and number of leaves at all observation times. The combination of JMS and liquid NPK fertilizer had no significant effect during the early growth stage (7 DAP), but showed significant effects on plant height and number of leaves at 14 and 21 DAP. These findings indicate that factorial application of JMS and liquid NPK fertilizer can enhance the growth of mustard greens, while their combination is effective at certain vegetative growth stages. Keywords: Brassica juncea L., jadam microbial solution, liquid NPK

Abstract

This study aims to investigate the effect of planting media composition and NPK Mutiara fertilizer application on the growth and yield of cherry tomato plants (Lycopersicum esculentum Mill.) in North Sumatra. The research method used a factorial Randomized Block Design (RBD) with two factors: planting media composition (topsoil, cow manure/compost/chicken manure, and rice husk) and NPK Mutiara fertilizer dosage (0, 15, 25, and 35 g/plot). The observed parameters included plant height, number of leaves, number of productive branches, number of fruits per plant, number of fruits per sample, fruit weight per plot, and fruit diameter. The results showed that neither the single effect nor the interaction between planting media and NPK Mutiara fertilizer had a statistically significant effect on the growth and yield of cherry tomatoes. Environmental factors are presumed to be more dominant in influencing the results. Keywords: planting media, NPK fertilizer, growth, yield
