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

Sugarcane (Saccharum officinarum L.) is a strategic crop that is the primary raw material for sugar and has an important role in the economy. Domestic sugar production has not met national needs due to various constraints, such as low yield, poor seed quality, and soil damage due to inorganic fertilizers. The application of amino acids as organic fertilizers can potentially increase sugarcane productivity by improving plant metabolism and soil microbial activity. This study aimed to determine the effect of amino acid administration on generative growth and the Brix value of sugarcane plants (Saccharum officinarum L.). Varieties of sea lining. The research was implemented from February to June 2024 at the Lapang Laboratory, Department of Agricultural Production, Politeknik Negeri Jember. The method used in the study is the Group Random Design (RAK) method, which involves 1 factor, namely, Amino Acid organic fertilizer has four levels of amino acid dosage, namely A0 = Control (without amino acid administration), A1 = Amino Acid 250 ml/polybag, A2 = Amino Acid 500 ml/polybag and A3 = Amino Acid 750 ml/polybag. The data obtained from the research results was analyzed using ANOVA and then further tested using BNJ at the level of 5%. The results of the study found that the application of amino acids to sugarcane plants (Saccharum officinarum L.) had a real effect on the height of the plant at 188 HST, the stem diameter of 218 and 249 HST, and very real on the stem diameter of 188 HST and the root volume of 249 HST. However, the effect was not significant on the plant height of 218 HST, 249 HST, and Brix values.

Abstract

Organic farming is a cultivation system that prioritizes using natural and environmentally friendly inputs to create sustainable agriculture. This research/implementation aims to determine the use of liquid organic fertilizer (POC), Jakaba, tofu waste POC, and refugia plants in supporting organic rice cultivation in conventional rice cultivation. Activities were carried out from March to May 2025 at the Timpag Rice Seed Farm, Tabanan, Bali. Jakaba liquid organic fertilizer and tofu waste were applied periodically with the spray method starting at 14 days after planting (HST) with an interval of two weeks until entering the generative phase. Meanwhile, refugia plants such as zinnia, kenikir, and widelia were planted around the cultivation field to support pest biological control. Parameters observed included plant height, number of productive tillers, and insect diversity index. The results showed that the application of POC and refugia can support the growth of rice plants and create a balanced agricultural ecosystem. Thus, the application of organic inputs and ecological approaches like this has great potential in supporting a productive and sustainable organic farming system.

Abstract

Mustard greens (Brassica sp.) are one of the horticultural plants widely cultivated by the community. Mustard production can be increased through fertilization activities. Mustard plants require balanced soil nutrients such as nitrogen, phosphorus, and potassium (N, P, K) to support optimal growth. Liquid organic fertilizer (POC) has been developed to reduce dependence on the use of inorganic fertilizers. POC made from shallots contains complete macro and micronutrients that can be utilized by mustard plants for optimal growth. This research aims to study the response of liquid organic fertilizer (POC) from shallots on the growth of various types of mustard greens. The research was conducted at the Jember State Polytechnic from June to August 2024, using a Factorial Randomized Block Design (RBD) with 3 replications, involving POC concentrations of 0, 20, 40, and 60 ml/L on the mustard varieties Pakcoy, Samhong, Pagoda, and Caisim. The results showed that the 60 ml/L POC concentration significantly increased the number of leaves and plant height in Samhong and Pagoda mustard greens at 40 days after planting.
