Abstract

The decline in productivity of mung beans (Vigna radiata L.) in Indonesia requires strategic efforts to increase yields. One approach studied in this study is the use of plant ZPT Paclobutrazol as a compound that inhibits vegetative growth, especially in the formation of branches that play an important role in plant yields. The purpose of this study was to determine the effect and magnitude of the inhibitory power of Paclobutrazol on the growth and yield of mung beans. The study was conducted in July–October 2024 in Sumbersari District, Jember Regency with an altitude of 160 meters above sea level. The design used was a Randomized Block Design (RBD) with five concentration treatments (0 ppm, 50 ppm, 100 ppm, 150 ppm, and 200 ppm) and five replications. The results showed that a concentration of 200 ppm Paclobutrazol gave the most significant inhibitory effect, reducing plant height by 33% compared to the control and producing fewer branches. However, yield variables such as biomass weight, pod weight, seed weight, and number of pods did not show significant differences between treatments. This indicates that Paclobutrazol is more dominant in inhibiting vegetative growth without providing a significant increase in the generative phase. This study concluded that the application of Paclobutrazol at high concentrations significantly inhibited the growth of mung beans but did not significantly affect the yield.

Abstract

Pulut corn is one of the corn varieties consumed by Indonesians for its nutritional content. However, its production has declined due to suboptimal land conditions, such as water deficit and low organic matter content. This research was conducted in Kebonsari, Sumbersari Subdistrict, Jember District, from August to October 2024, on land at 100 meters above sea level with a temperature of 26-31°C, humidity of 88-90%, and rainfall of 6-20 mm/day. The study used a non-factorial Randomized Group Design (RAK) with six doses of corn cob biochar (0.8 kg/m2, 1.6 kg/m2, 2.4 kg/m2, 3.2 kg/m2, 4 kg.m2, and 4.8 kg/m2) and four replications. Variables observed included vegetative growth and yield of pulut corn plants, such as plant height, stem diameter, number of leaves, sweetness content, cob length and diameter, and fresh and dry weight. The results showed that the biochar dose of 1.6 kg/m² gave a very significant effect on fresh cob weight per sample (1.08 kg) and dry weight per sample (0.23 kg). Meanwhile, the dose of 0.8 kg/m² had a significant effect on fresh weight (2.60 kg) and dry weight per plot (1.91 kg). Biochar effectively improves soil structure, increases microorganisms, and supports the growth and production of pulut corn.

Abstract

Corn is one of the food crops in Indonesia that has great potential to be developed, one of which is pulut corn. Pulut corn itself is corn with a high amylase content, but the yield of this corn is in the low category. One way to increase the productivity of pulut corn is the use of liquid organic fertilizer made from tofu waste. The research was carried out on the Jember State Polytechnic land in July-October 2024. Using RBD, which consists of a single treatment, namely the concentration of tofu waste. There are six treatment levels, including control, 26 ml/l, 28 ml/l, 30 ml/l, 32 ml/l, and 34 ml/l. The results of the observation parameters will be tested further with BNJ. From the six levels of treatment given, it was found that treatment with a concentration of 34 ml/l could reduce the stem diameter at 21 DAT, the weight of corn cobs per sample. A concentration of 30 ml/l affects the diameter of the cobs, while a concentration of 32 ml/l affects the weight of the cobs per plot. The parameters of plant height and biomass weight provide significant ups and downs.

Abstract

The low productivity of glutinous mays is caused by several factors, including infertile soil conditions and its high susceptibility to pests and diseases. These conditions hinder optimal plant growth and significantly reduce crop yields. Therefore, alternative environmentally friendly control measures are needed, one of which involves using biological agents such as Plant Growth-Promoting Rhizobacteria (PGPR) and mycorrhizae. This study aimed to analyze the effect of PGPR and mycorrhizal treatments on pest infestation intensity and the production yield of glutinous mays. The research was conducted from June to September 2024 in Duko Kembang Village, Bondowoso District, Bondowoso Regency, East Java Province. The experimental design used was a non-factorial Randomized Complete Block Design (RCBD) consisting of four treatments :(100% anorganic fertilizer), (50% anorganic fertilizer + PGPR), (50% anorganic fertilizer + mycorrhiza), and (50% anorganic fertilizer + PGPR + mycorrhiza). The observed parameters included: (1) agronomic parameters such as plant height, stem diameter, time to male and female flowering, cob weight, cob diameter, and cob length, and (2) pest infestation intensity by grasshoppers, armyworms, and downy mildew. Data were analyzed using ANOVA and followed by the DMRT test at a 5% significance level. The results showed that the treatments had no significant effect on either the agronomic parameters or the intensity of pest infestation.
