Abstract

The Impact of Green Mussel Shell Powder and KNO3 Fertilizer On the Growth and Yield of Edamame Soybean In Peat Soil. In Indonesia, edamame soybeans are a healthy and nutritious food choice, utilized as a new business opportunity in the soy-based food and beverage industry. Peat soil, as a planting medium, faces low pH levels, limiting nutrient availability. Green mussel shell flour can serve as an alternative material to neutralize soil acidity in peat soil because it contains calcium carbonate, which neutralizes peat soil acidity. This study aims to determine the best interaction dose of green mussel shell flour and KNO₃ fertilizer on the growth and yield of edamame plants in peat soil. The research was conducted in Southeast Pontianak District, Pontianak City, West Kalimantan. This research took place from August 2024 to November 2024. The design used in this study was a Factorial Completely Randomized Design (RAL) consisting of 2 treatments. The first factor was green mussel shell flour (K), consisting of 3 treatment levels: 0.84 tons/ha, 1.64 tons/ha, and 2.44 tons/ha, while the second factor was KNO₃ fertilizer (P), consisting of 3 treatment levels: 300 kg/ha, 450 kg/ha, and 600 kg/ha. Each treatment was repeated 3 times. The variables observed in this study included: plant height, root volume, plant dry weight, number of productive branches, number of pods per plant, pod weight per plant, number of empty pods per plant, and number of filled pods per plant. The results showed an interaction between the application of green mussel shell flour and KNO₃ fertilizer on the root volume and dry weight of edamame soybeans in peat soil. The application of green mussel shell flour at a dose of 0.84 tons/ha and KNO₃ fertilizer at a dose of 300 kg/ha, as well as the application of green mussel shell flour at a dose of 2.44 tons/ha and KNO₃ fertilizer at a dose of 300 kg/ha, showed an efficient dose on root volume, which was 21.33 cm3, and plant dry weight, which was 26.71 g/plant.adalah Rancangan Acak Lengkap Fakrorial (RAL) yang terdiri dari 2 perlakuan. Faktor pertama yaitu tepung cangkang kerang hijau (K) yang terdiri dari 3 taraf perlakuan yaitu 0,84 ton/ha, 1,64 ton/ha, dan 2,44 ton/ha, sedangkan faktor kedua yaitu pupuk KNO₃ (P) yang terdiri dari 3 taraf perlakuan yaitu 300 kg/ha, 450 kg/ha, dan 600 kg/ha. Masing masing perlakuan diulang sebanyak 3 kali dengan setiap ulangan terdiri dari 4 tanaman sample, sehinga jumlah tanaman seluruhnya adalah 108 tanaman. Variable yang diamati dalam penelitian ini meliputi: tinggi tanaman, volume akar, berat kering tanaman, jumlah cabang produktif, jumlah polong pertanaman, berat polong pertanaman, jumlah polong hampa pertanamna, dan jumlah polong isi pertanaman.  Hasil penelitian menujukan bahwa Terjadi interaksi antar pemberian tepung cangkang kerang hijau dan pupuk KNO3 terhadap volume akar dan berat kering tanaman kedelai edamame pada tanah gambut.

Abstract

Edamame has high yield potential; however, production in Indonesia remains limited. Edamame production on peatlands faces several obstacles, including the nature of peat, which often has low nutrient content and high acidity levels that do not support the formation of root nodules. One way to form root nodules to increase edamame productivity is to use salicylic acid and Bradyrhizobium bacteria. This study aims to determine the effects of the timing of salicylic acid and Bradyrhizobium treatment on edamame productivity in peatlands. This research was conducted in Siantan Hilir, North Pontianak, during July-September 2024. The experimental design used was a factorial RAL split-plot design consisting of two factors. The first factor is the treatment of Bradyrhizobium bacteria, and the second factor is the timing of salicylic acid treatment. There are six treatment combinations with 6 times replications. The variables observed include plant height, number of leaves, number of root nodules, root length, number of pods per plant, weight of pods per plant, yield per plot, and yield per hectare. The results showed no significant interaction between salicylic acid treatment and Bradyrhizobium bacteria. Salicylic acid treatment significantly affected the number of root nodules, number of pods per plant, weight of pods per plant, yield per plot, and yield per hectare. Still, it did not significantly affect plant height, leaf number, or root length. Bradyrhizobium bacteria treatment significantly affected the number of root nodules, number of pods per plant, weight of pods per plant, yield per plot, and yield per hectare. Still, it did not significantly affect plant height, leaf number, or root length. The treatment of salicylic acid and Bradyrhizobium bacteria individually had a significant effect on the number of root nodules, number of pods, pod weight, and yield per plot and per hectare.

Abstract

Chili pepper is included in the Family Eggplant (Solanaceae) and is a plant that is easily planted in the lowlands or in the highlands. There is considerable potential for developing vegetables, especially red chili plants, on alluvial soils in West Kalimantan. For this reason, it's necessary to increase red chili plant production by improving soil nutrient availability with cow manure. This study aims to analyze the effect of applying cow manure at different doses on the absorption of N, P, and K and the yield of red chili plants (Capsicum annum L). This research was conducted on the Pontianak Kota sub-district, and an Analysis of Soil Chemical Properties was carried out in the Laboratory of Chemistry and Soil Fertility. This study uses a non-factorial complete random design (RAL) with 5 treatments, each repeated 5 times, yielding 25 experimental units. Treatment doses P0 (without treatment), P1 30 tons/ha (157 g/ g/polybag), P2 60 tons/ha (315 g/ g/polybag), P3 90 tons/ha (473 g/ g/polybag), and P4 120 tons/ha (631 g/ g/polybag). The results of the effect of giving the best cow manure were found in the treatment of P3 90 tons/ha (473 g/ g/polybag), which could increase the dry weight of the plant by 10.29%, N 21,42%, absorption, P 16,66%, and K 17,61%.) g/polybag), P3 90 ton/ha (473 g/polybag), dan P4 120 ton/ha (631 g/polybag). Hasil penelitian pengaruh pemberian pupuk kandang sapi terbaik terdapat pada perlakuan P3 90 ton/ha (473 g/polybag) yang mampu meningkatkan berat kering tanaman sebesar 10,29%, N 21,42%, serapan, P 16,66%, dan K 17,61%.

Abstract

Naruto Kintoki sweet potato (Ipomoea batatas L.) is a superior variety valued for its sweet taste and soft texture, but its cultivation in Indonesia remains limited. This study aimed to examine the interaction between rice husk biochar application and harvest age on the yield of Naruto Kintoki grown in ultisol soil. The research was conducted in the Pontianak Kota District, from September 2024 to February 2025. A factorial Completely Randomized Design (CRD) was used with two factors: biochar (2, 4, and 6 tons/ha) and harvest age (90, 105, and 120 days). Results showed significant interaction effects on growth and yield. A harvest age of 120 days with 4 tons/ha biochar produced the longest main vine (176.79 cm) and the largest tuber diameter (55.28 mm). The highest tuber number (4.60) and tuber weight (447.51 g) were found with 120 days and 6 tons/ha biochar. This study contributes to scientific knowledge by demonstrating how biochar and harvest timing influence both yield and tuber quality. It supports the sustainable cultivation of Naruto Kintoki in acidic, nutrient-poor ultisol soils and provides a model for optimizing sweet potato production on marginal tropical lands.

Abstract

Sweet potato (Ipomoea batatas L.) is a widely cultivated crop in Indonesia, valued for its high economic potential and versatility. The Cilembu variety, originating from West Java, has been recognized for its high yield potential. This study aimed to determine the optimal harvest time for Cilembu sweet potatoes grown on PMK soil. Conducted from September 2024 to February 2025, the research employed a completely randomized design (CRD) with five treatments (harvest times: 3, 3.5, 4, 4.5, and 5 months) and four replications. Variables observed included fresh weight, dry weight, tuber weight, diameter, number of tubers, sugar content, moisture content, and fiber content. Results showed that harvest time significantly affected tuber diameter, tuber weight, and sugar content. The study concluded that harvesting at 4 months yields optimal tuber weight and diameter with standard fiber and moisture content, while the highest sugar content was achieved at 3.5 months. This research contributes to optimizing sweet potato cultivation practices, enhancing yield quality and quantity
