Abstract

Long bean is the one of the most widely consumed vegetables both fresh and processed. The market demand for long beans is rising, but their production remains limited. This study aims to investigate how different concentrations of paclobutrazol and various types of nitrogen fertilizers affect the growth and yield of long bean plants. The research was conducted in Dander Village, Dander District, Bojonegoro Regency, East Java. The study employed a factorial Randomized Block Design (RBD) with two factors: the concentration of paclobutrazol (P0 = control, P1 = 150 ppm, P2 = 200 ppm, P3 = 250 ppm) and the type of nitrogen fertilizer (N0 = NPK control, N1 = Urea, N2 = ZA, N3 = KNO3). Variables to observed included plant length, number of leaves, flowering age, number of pods, pod weight, number of seeds, and fruit set. The results showed that the combination of 150 ppm paclobutrazol and KNO3 nitrogen fertilizer produced the best results in terms of the fastest flower emergence at 29 days after planting (HST) and the highest pod weight of long beans at 43.00 grams per plant. Keywords: Paclobutrazol, Various Nitrogen Fertilizers, Growth, Yield, Long Beans (Vigna sinensis L.)

Abstract

The quality of soybean seeds, encompassing physical, physiological, and chemical attributes, is crucial for successful plant growth and yield. Effective seed storage is vital in maintaining seed viability, growth capacity, and adaptability, especially amid global challenges like climate change and rising food demand. This research aimed to identify the optimal packaging material and storage temperature to preserve soybean seed quality. Using a Split Plot Design with two factors and three replications, the study examined four storage temperatures (S0: 27.1°C, S1: 7-10°C, S2: 17-19°C, S3: 20-25°C) and three packaging types (K1: plastic-coated sack, K2: PE plastic, K3: aluminum foil). Results indicated that seeds stored at 27.1°C in plastic-coated sacks experienced increased moisture, reduced vigor, slower growth, lower germination, and altered protein and fat content. Conversely, PE plastic and aluminum foil packaging maintained seed quality over three months. All packaging types effectively preserved seed quality at cooler temperatures (7-25°C). This study underscores the importance of optimal storage conditions for sustainable soybean seed availability. Keywords: Packaging, Seed Quality, Soybean Seeds, Storage, Temperature.

Abstract

Efforts to improve the quality of the Anjasmoro soybean variety (Glycine max L. Merrill) include the use of seed coating techniques. Seed coating involves applying a layer of specific materials to seeds, serving as carriers for additional substances that extend seed shelf life, protect against pathogens, and stimulate plant growth. This study aimed to identify the most effective seed coating material to enhance soybean growth after storage for three months. Growth tests were conducted using the following treatments: FP 0 (control); FP 1 (CMC 1.5% + Liquid Smoke 0.5% + CaCO₃ 72 g + Gypsum 18 g); FP 2 (CMC 1.5% + Liquid Smoke 0.5% + CaCO₃ 72 g + Talc 18 g); FP 3 (CMC 1.5% + Liquid Smoke 0.5% + CaCO₃ 72 g + Pumice stone 18 g); FP 4 (CMC 1.5% + Liquid Smoke 0.5% + CaCO₃ 72 g + Quicklime 18 g); FP 5 (CMC 1.5% + Liquid Smoke 0.5% + CaCO₃ 72 g + Dolomite 18 g); and FP 6 (CMC 1.5% + Liquid Smoke 0.5% + CaCO₃ 72 g + Zeolite 18 g). Observations included plant height (cm), number of leaves, and number of branches. The study was conducted from April to October 2024 at the UPT Center for Rice and Secondary Crops Seed Development 2, Singosari District, Malang, using a randomized block design (RAK) with seven formulations of seed coating materials. Each treatment consisted of 16 plants with four replications. The research data were analyzed using ANOVA, followed by a BNJ (Honestly Significant Difference) test at the 5% significance level (BNJ 0.05). The results showed that the FP 1 treatment resulted in a plant height of 56.50 cm, 19.75 leaves, and 4.75 branches at 35 days after planting (DAP). The FP 1 treatment significantly enhanced growth, as indicated by plant height, leaf number, and branch number. FP 1 demonstrated the best combination of seed coating materials compared to other treatments at 21, 28, and 35 DAP
