Abstract

Plant Growth Promoting Rhizobacteria (PGPR) is a group of microorganisms that colonize plant roots and play an important role as a biostimulant, biofertilizer, and bioprotectant that can increase plant growth and productivity. This study aims to determine the effectiveness of Tallang bamboo root PGPR on the growth and production of peanut plants (Arachis hypogaea L.) elephant variety. The study was conducted from March 2025 to July 2025 in Lion Tondok Iring Village, North Makale District, Tana Toraja Regency, at an altitude of 828 meters above sea level. The research method used a Randomized Block Design (RBD) with one treatment factor, namely the concentration of Tallang bamboo root PGPR, which consisted of four treatment levels: P0 = without Tallang bamboo root PGPR (control), P1 = 15 ml/L water, P2 = 30 ml/L water, and P3 = 45 ml/L water. The variables observed included the number of pods per plant, fresh weight of pods per plant, dry weight of pods per plant, seed weight per plant, seed weight per plot, seed yield per hectare, and harvest index. The results showed that the application of Tallang bamboo root PGPR at a concentration of 30 ml/L water (P2) had the best effect on all growth and yield parameters, namely the number of pods per plant, fresh weight of pods per plant, dry weight of pods per plant, seed weight per plant, seed weight per plot, seed yield per hectare, and harvest index, compared to the control or other concentration treatments. Thus, it can be concluded that the application of Tallang bamboo root PGPR at a concentration of 30 ml/L water is the most effective dose to increase the growth and production of Gajah variety peanut plants.

Abstract

This study aimed to evaluate the effectiveness of liquid organic fertilizer (POC) derived from kirinyuh (Chromolaena odorata) leaves on the growth and yield of potted corn plants. The research was carried out at the Agricultural Development Center (BPP) of Malimbong Balepe’, Tana Toraja District, South Sulawesi Province, located at an altitude of 815 meters above sea level. The experiment was designed using a simple randomized block design (RBD) consisting of four treatments: K0 = control (without treatment), K1 = 20% concentration of kirinyuh leaf POC (200 ml POC + 800 ml water), K2 = 40% concentration of kirinyuh leaf POC (400 ml POC + 600 ml water), and K3 = 60% concentration of kirinyuh leaf POC (600 ml POC + 400 ml water). Parameters observed included plant height at 5 and 7 weeks after planting (WAP), number of leaves at 7 WAP, ear length, ear diameter, and ear weight per plant. The results showed that kirinyuh leaf POC significantly affected the growth and productivity of potted corn plants. Application of POC at 60% concentration (K3) produced the best results, indicated by increased plant height, greater number of leaves, longer ear length, larger ear diameter, and higher ear weight compared to other treatments and control. This finding suggests that kirinyuh leaves, which are often considered as agricultural weeds, have potential as an alternative source of organic fertilizer that is environmentally friendly, low-cost, and effective in improving crop growth and yield. In conclusion, kirinyuh leaf-based liquid organic fertilizer, particularly at a concentration of 60%, demonstrated the highest effectiveness in supporting corn growth and productivity. These results provide practical insights for farmers to utilize locally available organic materials as an alternative to chemical fertilizers in sustainable agricultural practices.

Abstract

A research project entitled Optimisation of Gandasil D Use to Increase Kale (Barassica Oleracea Var. Acephala) Productivity in Hydroponic Systems was conducted at the Pakkea Experimental Garden, Faculty of Agriculture, North Toraja Regency, from March to June 2025. This research project aims to determine the response of Ab mix nutrients and Gandasil D fertiliser in the DFT system to the growth and production of kale plants. The method used in this study was a randomised block design (RAK) with 6 levels of Gandasil D concentration. (KO = Control), (K1 = 0.5 grams/litre of water), (K2 = 1 gram/litre of water), (K3 = 1.5 grams/litre of water), (K4 = 2 grams/litre of water), (K5 = 2.5 grams/litre of water) with 3 replications and with AB MIX concentrations, 0 to 7 days after planting = 400 ppm, 8 to 14 days after planting = 600 ppm, 15 to 21 days after planting = 800 ppm, 22 to 28 days after planting = 1000 ppm, 29 to 35 days after planting = 1200 ppm, 36 days and onwards until harvest = 1500 ppm. The variables observed in this study were plant height, leaf length, leaf width, number of leaves, and plant stem diameter. The results showed that a concentration of Gandasil D 2.5 grams/litre of water gave the best results with an average plant height of 37.93 cm, 12.56 leaves, leaf length of 24.16 cm, leaf width of 14.31 cm, stem diameter of 11.69 mm, and harvest weight of 232.89/plant. The data were analysed using analysis of variance (ANOVA) and followed by a post hoc test at a significance level of 0.05. The analysis of the feasibility of farming showed an R/C ratio of 1.03, which means that kale cultivation using a hydroponic system and the aforementioned nutrient concentration is feasible and profitable.

Abstract

The use of organic materials as fertilizers is an important effort to improve soil fertility and crop productivity sustainably. Gliricidia sepium (gamal leaves) is a leguminous plant rich in nutrients such as nitrogen, phosphorus, and potassium, and contains bioactive compounds and microbes that support plant growth. Liquid organic fertilizer (LOF) made from fermented gamal leaves offers advantages including ease of application, high nutrient absorption by plants, and environmental friendliness compared to synthetic chemical fertilizers that may cause pollution and other negative impacts. This study aimed to evaluate the effect of LOF from gamal leaves on the growth and yield of Japanese cucumber (Cucumis sativus L.). The research was conducted at the Experimental Garden of the Faculty of Agriculture, UKI Toraja, South Sulawesi, from April to July 2025. The LOF was produced by fermenting gamal leaves for 15 days using EM-4 solution and palm sugar as activators. The LOF was applied three times at two-week intervals, starting at 7 days after planting (DAP), by soil drenching around the base of the plants. Observed variables included plant height, number of leaves, leaf area, stem diameter, number of fruits per plant and per plot, average fruit diameter and length, and fruit weight per plant and per plot. Data were analyzed using analysis of variance (ANOVA) and the Honestly Significant Difference (HSD) test at a 0.05 significance level. The results showed that application of LOF from gamal leaves at a dose of 300 ml per plant produced the best results across all observed parameters, including plant height, leaf number and area, stem diameter, fruit number, fruit size, and fruit weight per plant and per plot.

Abstract

Organic agriculture plays a vital role in Indonesia’s agricultural development, with a key challenge being how to boost productivity efficiently and sustainably. Liquid Organic Fertilizer (LOF) derived from natural materials provides an eco-friendly option to improve soil fertility and crop yields. Bamboo shoots (Bambusa spp.), rich in organic carbon and gibberellin, present strong potential as LOF raw material to support plant growth. This study evaluated the effect of bamboo shoot-based LOF on the growth and yield of white radish (Raphanus sativus). The research was conducted from May to August 2025 in Kalolok, Batupapan Village, Tana Toraja Regency, South Sulawesi, at an altitude of 775 m. LOF was produced by fermenting 200 kg of ground bamboo shoots with 4 kg palm sugar, 1 liter EM4, and 200 liters water for 14 days. Treatments consisted of 0, 100, 200, and 300 ml per liter of water, applied twice at two-week intervals starting 14 days after planting. Using a randomized block design with four treatments and three replications, variables observed included plant height, leaf number, tuber size, and yield. Results showed that 300 ml/liter LOF gave the best outcomes: tallest plants (27 cm), most leaves (15.89), largest tubers (29.37 cm length; 6.06 cm diameter), and highest weight (731 g/plant; 6936.67 g/plot). These effects are linked to balanced nutrients (N, P, K, Mg, Ca) enhancing vegetative growth and tuber development. Thus, bamboo shoot-based LOF at 300 ml/liter is recommended as an effective organic fertilizer for white radish.
