Abstract

Melon (Cucumis melo L.) is a fruit known for its sweet and refreshing taste. Traditionally, melon cultivation has relied on conventional farming methods. The use of biofertilizers offers an alternative to reduce dependency on synthetic fertilizers. This study aimed to enhance the production of healthy, high-yielding melon plants by substituting Mutiara NPK fertilizer with Bioto Grow Gold (BGG) biofertilizer. Conducted in Sukosongo Village, Kembangbau District, Lamongan Regency, East Java, the experiment employed a factorial Completely Randomized Design (CRD).Two factors were tested: BGG fertilizer at four concentrations (0 ml/L [P0], 1 ml/L [P1], 2 ml/L [P2], and 4 ml/L [P3]) and NPK fertilizer at four doses (0 g/plant [N0], 60 g/plant [N1], 70 g/plant [N2], and 80 g/plant [N3]). Results indicated that BGG fertilizer influenced both vegetative and generative growth variables, as did the Mutiara NPK fertilizer doses. The optimal combination was achieved with a BGG concentration of 3 ml/L and an NPK dose of 70 g/plant, which significantly increased the sucrose content in melons. Keywords: Bioto Grow Gold fertilizer, Biofertilizer, Melon, NPK Mutiara fertilizer.

Abstract

This study aimed to determine the optimal harvest time and packaging type to preserve the quality of Inpari 32 rice seeds during storage. Conducted at the Food and Horticultural Plant Seed Supervision and Certification Unit in East Java from November 2023 to April 2024, the research used a factorial experiment in a completely randomized design (CRD) with three replications. Harvest age treatments were 110, 120, 130, and 140 days after seedling (DAS), while packaging types included plastic sacks, polyethylene (PE) sacks, polypropylene (PP) sacks, and aluminium foil. Data were analyzed using ANOVA and Duncan's Multiple Range Test (DMRT) at a 5% significance level. Results showed that harvesting at 120 DAS with PP sacks yielded the highest starch content, while 140 DAS with aluminium foil resulted in the lowest reducing sugar content. Optimal germination and growth speed were achieved at 130 DAS, which also minimized electrical conductivity. Harvesting at 140 DAS produced the highest 1000-grain weight. Aluminium foil packaging maintained the lowest moisture content and significantly improved germination and growth speed compared to other packaging types. These findings suggest that optimizing harvest age and packaging type can significantly improve seed viability and storage performance.

Abstract

This study aimedto evaluate the effects of combined NPK fertilizer and guano application on the growth and yield of Bambara groundnut (Vigna subterranea (L.) Verdc.). The experiment employed a factorial randomized block design with two factors: NPK fertilizer dosage (25%, 50%, 75%, and 100% of recommended rates) and guano dosage (5, 10, and 15 tons/ha). Observed parameters included plant height, leaf count, number of flowers, number of pegs, and fresh/dry pod weight per plant. Results demonstrated that the combination of 25% NPK and 15 tons/ha guano significantly improved plant height (43.29 cm), flower count (47.33), and fresh pod weight (81.73 g/plant). Guano alone also exhibited a substantial effect on both vegetative and generative growth, with the highest results observed at 15 tons/ha. The combination of low NPK and high guano dosages enhances Bambara groundnut productivity sustainably.

Abstract

Chili pepper (Capsicum frutescens L.) is an important horticultural crop that requires sufficient production to meet increasing market demand. This study aimed to evaluate the effects of Biosaka elicitor composition and concentration on the growth and yield of chili pepper. The experiment was arranged in a two-factor factorial Randomized Complete Block Design (RCBD) with three replications. The first factor was Biosaka composition (J), consisting of five formulations: J1 = babandotan, J2 = J1 + pukul empat, J3 = J2 + patikan kebo, J4 = J3 + meniran, and J5 = all biosaka materials. The second factor was Biosaka concentration (K), consisting of three concentration levels: K1 = 1.5 mL/L, K2 = 2.5 mL/L, and K3 = 3.5 mL/L. The results showed that Biosaka composition significantly affected plant height at 21–63 DAT, stem diameter at 28–63 DAT, leaf number at 21–63 DAT, fruit number per plant at the fifth harvest, and fruit weight per plant at the first and fifth harvests. Biosaka concentration significantly affected plant height at 21 DAT and 42–56 DAT, leaf number at 49 and 56 DAT, and fruit number (total fruit number and fruit number per plant) at the first, fourth, and fifth harvests. Overall, the J5 formulation and the concentration of 2.5 mL/L tended to produce the most favorable growth responses in chili pepper plants.

Abstract

Terung (Solanum melongena L.) ialah tanaman sayuran kaya akan nutrisi yang menyehatkan. Bertambahnya kesejahteraan warga untuk hidup sehat berdampak pada kenaikan konsumsi sayuran salah satunya adalah terung oleh sebab itu, produksi tanaman terung di Indonesia perlu ditingkatkan. Kekeringan ialah faktor lingkungan yang berpengaruh besar kepada penurunan produksi terung. Pemilihan varietas unggul menjadi komponen penting untuk menciptakan produktivitas tinggi. Penelitian ini bertujuan menganalisis respon ke lima varietas terung ungu akibat cekaman kekeringan sehingga didapatkan varietas terung ungu yang tahan kepada cekaman kekeringan. Penelitian ini disusun secara faktorial menggunakan Rancangan Acak Lengkap (RAL) yang diulang sebanyak 3 kali. Faktor pertama ialah perlakuan cekaman kekeringan dengan 2 taraf yakni tidak diberi perlakuan cekaman atau kontrol dan diberi perlakuan cekaman, faktor kedua ialah macam varietas dengan 5 taraf yaitu Antaboga-1, Lezata F1, Mustang F1, Ratih Ungu, serta Panjalu F1. Varietas Antaboga (V1) mempunyai hasil yang lebih baik dibandingkan dengan keempat varietas terung ungu lainnya dan perlakuan cekaman kekeringan (C1) mampu menurunkan hasil produksi dibandingkan dengan perlakuan kontrol (C0).

Abstract

Background: Pakcoy (Brassica rapa) production in Indonesia continues to rise, reaching 635,982 tons in 2018 and 652,723 tons in 2019. Improper irrigation often causes wilting and root rot. The wick hydroponic system offers a viable alternative but is suitable mainly for crops requiring limited water. Inorganic fertilizers enhance growth and yield, their long-term use poses environmental and human health risks. Organic fertilizers provide a sustainable solution without leaving harmful residues. Optimizing pakcoy cultivation in hydroponic systems requires selecting an appropriate wick material and the optimal concentration of organic fertilizer to achieve sustainable productivity. Methodology: This research was conducted with factorial experiment using a 2-factor completely randomized design, the first factor is the fertilizer concentration treatment consisting of 4 types (N0: AB Mix 3 ml/L-control, N1: LOF 6 ml/L, N2: LOF 9 ml/L, N3: LOF 12 ml/L) and the second factor is the type of wick treatment consisting of 4 types (S0: Flannel cloth wick-control, S1: Coconut fiber wick, S2: Bamboo fiber wick, S3: Banana stem wick). If the results obtained have significant, then continue the 5% DMRT test. Findings: The combined treatment of AB Mix at 3 ml/L and a coconut fiber wick exerted a significant influence on plant height between 15 and 25 DAP (13.37 cm), as well as on several yield parameters at 30 DAP, including crown fresh weight (17.97 g), root fresh weight (3.60 g), total fresh weight (21.57 g), and weight loss (0.24 g). The coconut fiber organic wick independently produced significant effects across all observed parameters, except for the number of leaves recorded at 5 DAP. Overall, the interaction between AB Mix at 3 ml/L and the coconut fiber wick demonstrated effective in enhancing the performance of pakcoy (B. rapa L.) compared with other treatment combinations. Contribution: This study provides valuable insights into optimizing the combination of fertilizer concentration and organic wick type in wick hydroponic systems to enhance the sustainable performance growth of pakcoy while promoting the utilization of environmentally friendly local materials
