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

Peanuts are plants that are included in the secondary crops. However, the application of inorganic phosphorus fertilizer with continuous use can reduce soil quality, thereby reducing the yield of peanut harvests. The use of Pseudomonas fluorescens bacteria can increase phosphate absorption in peanuts so that it can reduce the dose of inorganic P fertilizer. This study was conducted from August to November 2024. Using the non-factorial RBD (randomized block design) method with Pseudomonas fluorescens bacterial concentration treatment consisting of control (without concentration), 20 ml/l, 30 ml/l, 40 ml/l, 50 ml/l, and 60 ml/l and a reduction of ¼ dose of SP-36 fertilizer. The parameters observed included plant height, dry biomass weight, fresh pod weight per sample, dry pod weight per sample, dry seed weight per plot, weight of 100 seeds, and number of root nodules. The results will be analyzed using ANOVA analysis of variance and DMRT further test. The administration of Pseudomonas fluorescens with a concentration of 50 ml/l + 75 kg/ha can provide a significant difference in the parameters of fresh pod weight per sample of 106.1 g and a concentration of 30 ml/l + 75 kg/ha affects the weight of dry pods weighing 71.60 g, dry seed weight of 648.8 g, weight of 100 seeds with a total of 57.95 g, and the number of root nodules of 24.21. For the parameters of plant height and dry biomass weight showed insignificant results.

Abstract

Soil microorganism activity is inhibited during the dry season, especially in dry land. Mulching is one of the efforts to maintain soil moisture and microorganism activity. This study aims to examine the growth response plant edamame against the use of mulch straw and application PGPR (Plant Growth Promoting Rhizobacteria). Conducted from July to September 2024 in Kaliurang Village, Jember with an altitude of 146 meters above sea level. This experiment was designed using factorial RAK consisting of two factors and three replications. Factor First that is concentration PGPR Which consists of from 0 ml/l (control), 12.5 ml/l and 25 ml/l, while the second factor is the thickness of straw mulch consisting of 2.5 cm, 4.5 cm, And 6.5 cm. Results study This show existence interaction from PGPR And mulch straw on treatment mulch 6.5 cm + 12.5 ml/l with tall 17.30 cm 24 HST. In the treatment (4.5 cm + PGPR 12.5 ml/l) it influenced the height plant age 32 HST (23.00 cm), amount pod per sample 20.13 pod and biomass dry18.53 g, whereas amount branch per sample on treatment (0 ml/l + 6.5 cm) 1.93 branches. However, the weight of pods per sample and the weight of pods per plot did not happen interaction. Heavy pod per sample on concentration 25 ml/l (55.02 g), at a mulch thickness of 4.5 cm (54.31 g). Pod weight per plot 1255.89 g (25 ml/l) and 1253.22 (4.5 cm). Use mulch straw allegedly capable guard humidity soil so that the microorganisms in PGPR are able to grow well and activity microorganisms in a way can directly influence growth and edamame crop yields.

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.
