Abstract

This study aims to evaluate the effect of soil tillage systems and NPK fertilizer doses on the growth and yield of sweet corn (Zea mays L.). The study was conducted using a two-factor factorial RAK, namely soil tillage (no tillage, minimum, and maximum) and NPK doses (0, 60, 90, and 120 g/plot). The results showed that the maximum soil preparation treatment (O3) and NPK fertilizer rate of 120 g/plot (P3) generally yielded the best results. However, the combination of O1P2 (no soil preparation + 90 g of fertilizer) also showed high yields on certain parameters, indicating the potential for fertilizer efficiency without the need for intensive soil preparation. This study underscores the importance of combining appropriate land management and fertilization practices to sustainably enhance sweet corn productivity. Keywords: sweet corn, soil tillage system, NPK fertilizer, growth, yield

Abstract

Ipomoea reptans P. commonly known as water spinach, is a leafy vegetable with high economic value and is widely consumed by the Indonesian population. This plant is extensively cultivated due to its short harvest cycle of approximately 25–30 days after planting, which provides farmers with the opportunity to increase land productivity. This study was conducted on agricultural land at the Universitas Pembinaan Masyarakat Indonesia (UPMI), Medan, from June to August 2025. A factorial Randomized Block Design (RBD) 4×4 with three replications was employed. The first factor was the Auxin Plant Growth Regulator (PGR) with four levels: Z0 = control, Z1 = 50 ml/L, Z2 = 100 ml/L, and Z3 = 150 ml/L. The second factor was POC PSB with four levels: P0 = control, P1 = 50 ml/L, P2 = 100 ml/L, and P3 = 150 ml/L. The results indicated that the application of Auxin PGR significantly affected the production parameters, with treatment P2 (100 ml/L) yielding a fresh weight of 58.1 grams. Furthermore, the interaction between Auxin PGR and POC PSB had a highly significant effect on the fresh weight of plants. The optimal combination was found in treatment Z3P2 (150 ml/L Auxin + 100 ml/L POC PSB), resulting in a fresh weight of 65.7 grams. In conclusion, the combined application of 150 ml/L Auxin PGR and 100 ml/L POC PSB significantly enhances the growth and yield of Ipomoea reptans and represents an environmentally friendly alternative technology to improve horticultural productivity. Keywords: ipomoea reptans, auxin plant growth regulator, POC PSB, growth, yield

Abstract

Eggplant (Solanum melongena L.) is a vegetable crop cultivated for its fruit, which is used as a food ingredient, either consumed fresh or processed into various dishes due to its pleasant taste. The decline in purple eggplant production can be caused by several factors, including poor soil fertility, inadequate cultivation practices, and improper fertilizer use. This study aims to analyze the effect of compost and NPK 16:16:16 fertilizer on the growth and yield of purple eggplant, as well as the interaction between the two types of fertilizers. The research was conducted at the experimental field of the Faculty of Agriculture, Universitas Pembinaan Masyarakat Indonesia, using a factorial randomized block design (RBD). The factors tested were compost doses (0, 1, 2, and 3 kg/plot) and NPK 16:16:16 doses (0, 50, 100, and 150 grams/plot). Eggplant growth data were measured at 14, 21, and 28 days after planting and analyzed using ANOVA followed by Duncan's multiple range test. The results showed that the best fertilizer treatment for eggplant growth was the combination of 3 kg compost/plot and 150 g NPK/plot, which resulted in a plant height of 70.3 cm. This indicates that the combination of both fertilizers significantly improved plant growth compared to other treatments. Keywords: eggplant, compos, NPK fertilizer

Abstract

This study aimed to examine the effect of Arbuscular Mycorrhizal Fungi (AMF) and cow manure fertilizer on the growth and yield of purple eggplant (Solanum melongena L.), as well as their interaction in enhancing productivity. The research was conducted using a factorial Randomized Block Design (RBD) with two factors. The first factor was AMF (M) with four levels: M0 = without AMF, M1 = 10 g/plot (100 kg/ha), M2 = 15 g/plot (150 kg/ha), and M3 = 20 g/plot (200 kg/ha). The second factor was cow manure fertilizer (P) with four levels: P0 = without cow manure, P1 = 1 kg/plot (10 tons/ha), P2 = 2 kg/plot (20 tons/ha), and P3 = 3 kg/plot (30 tons/ha). The observed parameters included plant height, number of leaves, number of branches, fruit diameter, fruit length, number of fruits per plot, and fruit weight per plot. The results showed that AMF significantly affected all growth and yield parameters. Cow manure fertilizer significantly influenced most parameters, especially fruit diameter, fruit length, number of fruits, and fruit weight. The interaction between AMF and cow manure fertilizer had a significant effect on yield parameters but was not significant for all vegetative growth parameters. Overall, the combination of 15–20 g/plot AMF with 2–3 kg/plot cow manure produced optimal growth and yield of purple eggplant..

Abstract

This study aimed to evaluate the effect of coconut water seed soaking duration and flash fertilizer application on the growth and yield of mung bean (Vigna radiata L.). The experiment was conducted at the experimental field of the Faculty of Agriculture, Indonesian Community Development University, Medan, from May to August 2024. A Randomized Block Design (RBD) with two factors and three replications was employed. The first factor was coconut water soaking duration (0, 2, 4, and 6 hours), while the second factor was flash fertilizer application (0, 0.25, 0.5, and 1 cc/L). Observed parameters included plant height, number of leaves, flowering age, pod weight per plant, and pod weight per plot. Results indicated that a soaking duration of 6 hours (P3) had a highly significant effect on all observed parameters, producing the highest plant height, leaf number, and pod weight. Similarly, flash fertilizer at 1 cc/L (K3) promoted better vegetative and reproductive growth compared to other treatments. The interaction of P3K3 produced the best performance across growth and yield traits. These findings suggest that combining coconut water seed soaking for 6 hours with flash fertilizer application at 1 cc/L is an effective strategy to enhance mung bean productivity. Keywords: mung bean, coconut water, flash fertilizer, growth, yield

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
