Abstract

The use of organic fertilizer provides soil with macronutrients, micronutrients, and organic acids which improve the long-term physical, chemical, and biological fertility of the soil. This research aims to: 1) Increase physical and chemical soil fertility, 2) Acquire the interaction between organic fertilizer and Ponska fertilizer dosage on sweet corn crops, 3) Acquire the most efficient dosage of PONSKA  fertilizer on sweet corn, and 4) disseminate research results through journal articles and directly to farmers.  This research will increase the efficiency of NPK Ponska chemical fertilizers by utilizing waste from around the farm and lakes to formulate organic fertilizer to apply on sweet corn crops and as a reference to teaching material. Factorial research with two factors was designed using a randomized block design. Factor I (A) = Organic fertilizer formulation, comprising of A1 = 20 ton/ha, A2 = 30 ton/ha, and A3 = 40 ton/ha.  Factor II (B) =  Phonska fertilizer,  comprising of B1 = 25 % Ponska, and B2 = 50% Ponska. Every treatment was replicated four times, yielding 24 research plots. Response variables observed were: Plant height, number of leaves, dry weight of the plant. Data were analyzed using ANOVA, followed by Tukey's honest significance difference test (alpha = 0.05) if significant differences were found. Results showed that the interaction between organic and Phonska fertilizer formulations had significant effects on plant height. A dosage of 40 ton/ha of organic fertilizer can decrease the use of phonska fertilizer by 75% based on the height of sweet corn plants.

Abstract

Conventional agriculture relies on the use of artificial chemical fertilizer, such as urea,during every planting season, causing a decrease in soil fertility. Unfertile land has a negative effect on rice production, putting strain on farmers.A replacement or complement for chemical fertilizers needs to be found; other than the negative long-term effects, increased demand for urea in the planting season can make it hard to find when farmers need it most. An organic alternative is kirinyu (Chromolaena odorata) which has high concentrations of nitrogen and also phosphorous, potassium, and other micronutrients. Kirinyu grows abundantly around rural farms and plantations and makes up a lot of local biomass. The aims of this research are to 1) Assess the interaction of kirinyu organic fertilizer dosage and urea dosage towards the growth of rice (Oryza sativa L.), and 2) determine the most efficient dosage of kirinyu and urea fertilizer for the best growth in rice. The research used a randomized block factorial design. The treatments were:Factor I (A) = Dosage of kirinyu organic fertilizer. A1 = 10 tons/ha, A2 = 20 tons/ha. Factor II (B) = Dosage of urea fertilizer. B1 = 50 kg/ha, B2 = 100 kg/ha, B3 = 100 kg/ha. Each treatment was replicated three times, resulting in 18 experiment plots. Variables observed were:height of plant and number of seedlings. Data was analyzed using analysis of variance and Least Significant Differences (LSD) at a test level of 5%. Results show that the combination of kirinyu organic fertilizer and urea fertilizer has a significant effect on plant height and number of rice seedlings.

Abstract

Sweetleaf stevia (Stevia rebaudiana Bertoni) is one of the potential sugar-producing plants besides sugar cane which is widely used as a natural non-calorie sweetener. Propagation of stevia by shoot cuttings produces more uniform seedlings. Plant Growth Promoting Rhizobacteria (PGPR) contains a group of beneficial bacteria that live in the plant root ecosystem that can stimulate plant growth. This study aims to determine the effect of PGPR on the growth of stevia cuttings and the best concentration of PGPR on the growth of stevia cuttings. This study was conducted in February-May 2024 in Kolongan Atas II Village, Sonder District, Minahasa Regency, North Sulawesi Province. The study used a Completely Randomized Design (RAL), with 5 treatment levels, namely P0 = Control (Without PGPR), P1 = PGPR 10 ml/liter of water, P2 = PGPR 20 ml/liter of water, P3 = PGPR 30 ml/liter of water and P4 = PGPR 40 ml/liter of water. Each treatment was repeated 4 times.The results showed that the aplication of PGPR affected the growth of stevia cuttings. The best PGPR concentration for the growth of stevia cuttings was at a PGPR treatment concentration of 20 ml/liter of water.  Keywords: plant growth promoting rhizobacteria, stevia
