Abstract

This study aimed to evaluate the effect of cow manure and NPK fertilizer application on the growth and production of sweet corn (Zea mays L. Saccharata Sturt). The study was conducted from June to October 2024 at the experimental garden of the Faculty of Agriculture, Universitas Pembinaan Masyarakat Indonesia, Medan Amplas. A Randomized Block Design (RBD) was used, with two factors studied: cow manure application (0%, 25%, and 50%) and NPK fertilizer (0 g, 0.5 g, and 1 g per plant). Each treatment was repeated three times, resulting in a total of nine experimental units. The results showed that cow manure application had a significant effect on plant height but did not affect the number of leaves, cob length, or cob weight per plot or per sample. Meanwhile, NPK fertilizer application did not show a significant effect on all parameters measured. The interaction between cow manure and NPK significantly affected the number of leaves at 6 WAP but did not affect plant height at 2 WAP, 4 WAP, and 6 WAP, as well as on cob length, cob weight per plot, and cob weight per sample. This study provides insight into the effectiveness of using organic and inorganic fertilizers in increasing sweet corn productivity. Keywords: sweet corn, cow manure, npk fertilizer

Abstract

Mitra dari kegiatan pelatihan adalah kelompok tani padi dan masyarakat di Kelurahan Lobusona, Kecamatan Rantau Selatan, Kabupaten Labuhanbatu. Saat ini petani di Kelurahan Lobusona cenderung memilih menggunakan pupuk kimia dari pada pupuk organik. Penyebabnya adalah karena kandungan hara pupuk kimia lebih tinggi, mudah diperoleh secara instan dan harga yang tinggi. Kesulitan mendapatkan pupuk kandang saat musim tanam membuat petani harus tergantung terhadap pupuk kimia yang mahal, sehingga petani mencoba mencari jalan keluar mengurangi ketergantungan terhadap pupuk kimia. Kegiatan pelatihan dilaksanakan pada tanggal 29 April 2025 diikuti oleh 30 peserta. Pelatihan dilaksanakan dengan cara pemaparan materi mengenai MOL limbah sayuran. beberapa solusi yang coba ditawarkan kepada petani tersebut yaitu: memberikan informasi dan penyuluhan bagi petani mengenai pentingnya peran dan kandungan MOL terutama limbah sayuran, serta manfaat penggunaan MOL limbah sayuran terhadap produksi padi.

Abstract

This study aims to determine the effect of dolomite and SP-36 fertilizer on the growth and production of red chili plants (Capsicum annum L.). The hypothesis tested in this study is the existence of a single response to dolomite and SP-36, as well as the interaction of both on the growth and production of red chili. The study was conducted from May to July 2024 at the experimental garden of the Faculty of Agriculture, Indonesian Community Development University (UPMI) Medan, using a factorial Randomized Block Design (RAK) with two factors: (1) Dolomite with three levels (D0 = without dolomite, D1 = 5 g/plot, D2 = 10 g/plot) and (2) SP-36 with three levels (S0 = without SP-36, S1 = 4.03 g/plot, S2 = 6.03 g/plot), with 9 treatment combinations. The results showed that dolomite administration had a very significant effect on the number of branches, fruit weight of sample plants, and fruit weight per plot, but was not significant on plant height and number of leaves at all observation ages. The treatment of dolomite 10 g/plot (D2) gave the best results for most parameters compared to the control (D0) and a dose of 5 g/plot (D1). The application of SP-36 fertilizer also had a very significant effect on the weight of the sample plant fruit and the weight of fruit per plot, but was not significant on plant height, number of leaves, and number of branches. The treatment of SP-36 at a dose of 6.03 g/plot (S2) showed the best results on several growth and production parameters. The interaction between dolomite and SP-36 had a very significant effect on the number of branches and weight of fruit per plot, but was not significant on other vegetative parameters. This study shows that the application of dolomite and SP-36 fertilizers significantly increases the production of red chili plants, especially in terms of the number of branches and fruit weight, with optimal doses of dolomite 10 g/plot and SP-36 6.03 g/plot. Keywords: dolomite fertilizer, SP-36, red chili

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 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
