Abstract

This study aims to analyze the influence of production factors on soybean farming results in Deli Serdang Regency within the framework of the Special Effort Program (Upsus) PAJALE. The production factors analyzed include land area, seeds, fertilizers, labor, and pesticides. The research method used is a quantitative approach with Cobb-Douglas production function analysis using cross-section data of 90 farmer respondents. The results of the study indicate that partially the variables of land area, seeds, and fertilizers have a positive and significant effect on soybean production, while labor and pesticides have a positive but insignificant effect. Simultaneously, all independent variables have a significant effect on soybean production with an F count of 61.150 and a significance level of 0.000. The coefficient of determination (Adjusted R²) of 0.772 indicates that 77.2% of the variation in soybean production can be explained by production factors in the model, while the rest is influenced by other factors outside the study. The results of the technical efficiency analysis indicate that the use of land area, seeds, and pesticides is still in an inefficient condition (increasing returns to scale), so there is still potential for improvement. Meanwhile, fertilizer and labor use are inefficient (decreasing returns to scale), necessitating adjustments. Therefore, increasing soybean production in Deli Serdang Regency depends not only on additional inputs but also on efficient management of production factors and support from the Upsus PAJALE program.

Abstract

Long beans (Vigna sinensis L.) are a horticultural commodity that has great potential to be developed in Indonesia because it is in great demand and has a fairly high economic value. The purpose of this research is to 1. determine the effect of humic acid fertilizer and SP-36 fertilizer and the interaction of the two treatments on the growth of long beans (Vigna sinensis L.). This research will be carried out in the research area located at Jalan Gunung Bendahara 10, South Binjai District, Binjai City. This research was conducted in May to June 2025. This research was conducted using a Factorial Randomized Block Design (RAK) with 2 (two) treatment factors, namely factor I, namely humic acid consisting of 3 (two) treatment levels, namely H0: dose 0 L / ha (without humic acid) (Control), H1: dose 30 L / ha (3 ml / plant), H2: dose 60 L / ha (6 ml / plant), Factor II, namely P fertilizer (SP-36) consisting of 3 (three) treatment levels, namely S0: 0 g / plant (Control), S1: 0.6 g / plant, S2: 1.2 g / plant. The parameters observed include plant height and flowering age. The results of the study showed a significant effect on the treatment of humic acid fertilizer on the growth of long bean plants (Vigna sinensis L). There was a significant effect on P fertilizer (SP-36) on the growth of long bean plants (Vigna sinensis L). There was a significant interaction effect between humic acid and P fertilizer (SP-36) treatments on the growth of long beans (Vigna sinensis L.).Keywords: Long beans, SP36 fertilizer, humic acid

Abstract

Tomato plants face various challenges, including decreased soil fertility, pest and disease attacks, and the significant impact of climate change on plant productivity. The use of biofertilizers is very relevant to increase tomato growth. The aim of this study was to determine the effect of the dosage of Bioneensis Biofertilizer and Single Fertilizer N, P, K as well as the interaction between the dosage of Bioneensis Biofertilizer and Single Fertilizer NPK on tomato plant growth. This study was conducted on Jl. A.H Nasution, Medan Johor District, Medan City. The research period starts from March to July 2025. This research uses a Factorial Randomized Block Design consisting of 2 factors, namely the first factor is the dose of Bioneensis Biofertilizer (B) where B1 = 10 g / plant, B2 = 20 g / plant, B3 = 30 g / plant, and the second factor is Single Fertilizer N, P, K (P), where P1 = Urea 50 kg / ha (9.6 g / plot), SP36 37.5 kg / ha (7.2 g / plot), KCl 25 kg / ha (4.8 g / plot), P2 = Urea 100 kg / ha (19.24 g / plot), SP36 75 kg / ha (14.44 g / plot), KCl 50 kg / ha (9.6 g / plot), P3 = Urea 200 kg / ha (38.48 g / plot), SP36 150 kg / ha (28.88 g/plot), KCl 100 kg/ha (19.24 g/plot). The results of the study showed that the use of Bioneensis Biofertilizer doses had no significant effect on plant height and number of leaves, with the best treatment being B2 (Bioneensis Biofertilizer 20 g/plant). The use of Single Fertilizer N, P, K (P) had no significant effect on plant height, number of leaves with the best treatment being P2 (Urea 100 kg/ha (19.24 g/plot), SP36 75 kg/ha (14.44 g/plot), KCl 50 kg/ha (9.6 g/plot). The interaction between Bioneensis Biofertilizer (B) and Single Fertilizer N, P, K had no significant effect on plant height, number of leaves with the best treatment being B2P3 Bionensis Biofertilizer 20 g/plant and Single Fertilizer N, P, K.

Abstract

Oil palm is a palm plant that produces edible oil, industrial oil and biodiesel (biofuel). Unfortunately, the productivity of oil palm plantations nationally is still low, especially smallholder plantations managed individually. The level of oil palm production is influenced by various factors, including environmental factors where it grows, the quality of the seeds used and cultivation and management techniques in its cultivation. The purpose of this study was to determine the effect of the weight size of oil palm seeds (Elaeis guineensis Jacq.) and soaking in KNO3 solution and the interaction of the combination between the weight size of seeds and soaking in KNO3 solution on the germination of oil palm plants (Elaeis guineensis Jacq.). This study was conducted in a research area located at the Oil Palm Research Center (PPKS) Sei Aek Pancur Tanjung Morawa Deli Serdang Regency. This research was conducted from April to June 2025. This research was conducted using a Factorial Completely Randomized Design (CRD) consisting of 2 treatment factors, namely the seed weight size factor consisting of 3 levels, namely V1: seed weight size 0≤1 gram, V2: seed weight size 1.1≤2 grams, V3: seed weight size 2.1≤3 grams. The KNO3 Soaking Factor consists of 3 treatment levels, namely P0 = Control (soaking using water for 24 hours), P1 = KNO3 concentration 0.2% + soaking time 12 hours, P2 = KNO3 concentration 0.2% + soaking time 18 hours. The parameters observed in this study were germination rate (%), germination rate index, and dormancy index (%). The effect of soaking in KNO3 solution on the germination of oil palm (Elaeis guineensis Jacq.) plants. The best treatment of several parameters in breaking oil palm seed dormancy was by soaking the seeds in KNO3 concentration of 0.6% for 18 hours. The combined interaction between seed weight size and KNO3 solution soaking on the germination of oil palm (Elaeis guineensis Jacq.) plants had a significant effect.Keywords: Oil Palm, Germination Rate, Variety
