Abstract

This study aimed to evaluate the effect of auxin soaking and planting spacing on the growth and yield of yam bean (Pachyrhizus erosus L.). The experiment was conducted in Paya Pasir, Medan Marelan, North Sumatra, from March to July 2025, using a factorial Randomized Block Design (RBD) with two factors: auxin soaking duration (0 hours, 1 hour, 2 hours) and planting spacing (20×20 cm, 20×25 cm, 20×30 cm), each with three replications. The results showed that auxin soaking had a significant effect on vine length at 3 weeks after planting (WAP), whereas planting spacing had no significant effect on all measured parameters. The interaction between the two factors significantly affected vine length, tuber weight per sample, tuber weight per plot, and brix value. The best combination was obtained from treatment P1J1 (1 hour soaking and 20×25 cm spacing), producing the highest tuber weight per plot (574 g). These findings indicate that a combination of moderate auxin dosage and close planting spacing can enhance the productivity of yam bean. Keywords: jicama, auxin, planting spacing, growth, yield

Abstract

This study aims to determine the response of growth and production of Kailan (Brassica oleracea var. Alboglabra) to Gedebog Banana POC and cow manure with different administrations. The study was carried out, Johor Village, Medan Johor District, North Sumatra from August 2019 to November 2019. The method used in this study was a Factorial Randomized Block Design (RAK) consisting of two factors, namely: POC Gedebog Banana Dose Factor (A1 = 200ml /L; A2 = 300ml/L and A3 = 400ml/L.). Dosage Factor of Cow Manure (K1 = 5 tons/ha; K2 = 10 tons/ha and K3 = 15 tons/ha). Giving POC Gedebog bananas showed significantly different effects on plant height, wet weight per plant and dry weight of kailan plants, but did not show a significantly different effect on the number of plant leaves. The application of cow manure showed no significant effect on all variables. The interaction of Gedebog Banana POC administration with Cow Manure showed a significantly different effect on plant height and dry weight per plant, but showed no significant effect on the number of plant leaves.

Abstract

The purpose of this study was to determine the growth of oil palm plants by giving empty bunch and NPK. This research was carried out in the people's garden in Binjai City, North Sumatra from January to April 2024. The research used a Factorial Randomized Group Design (RAK) with 2 treatment factors, the first factor of empty bunch consisted of 3 treatment levels, namely T0 = No empty bunch (Only Topsoil), T1 = 50% Topsoil and 50% empty bunch fermentation 2 Weeks, T2 = 50% Topsoil and 50% empty bunch fermentation 4 Weeks. The second factor is NPK with three treatment levels, namely N0 = 0 ml, N1 = 15 ml, and N2 = 25 ml. The parameters observed were stem diameter (mm), plant height (cm), leaf area (cm2), and number of leaves (strands). In this study, empty bunch treatment only had a significant effect on the growth of the number of leaves, and had no significant effect on the growth of stem diameter, plant height, and leaf area. NPK treatment only significantly affects the growth of stem diameter, but does not significantly affect the growth of plant height, leaf area, and number of leaves. The interaction between empty bunch and NPK treatments had no significant effect on the growth of stem diameter, plant height, leaf area, and number of leaves.

Abstract

This research was carried out at the UPTD BIH Gedung Johor, Medan Johor, Medan City, starting from December 2023 to February 2024. This research aims to determine the effect of cucumber plant growth and production on the provision of potassium silica and cow manure. This research used a factorial randomized block design (RAK) with 2 treatment factors. The first factor is potassium silica with the symbol (K) which consists of 3 treatment levels, namely: Ko = Without potassium silica 0-gram polybag, Ki = 2.5 cc/ liter of water, K2 = 5 cc/ liter of water. The second factor is cow manure with the symbol (S) which consists of 4 treatment levels, namely: So = No fertilizer, S = 100 grams/polybag, S2 200 grams polybag, and S: = 300 grams/polybag. The parameters observed in this study were plant length (cm), number of leaves (strands), flowering age (days), number of fruit per plant (fruit), weight of fruit per plant (kg), number of fruit per plot (fruit), weight of fruit per plot (kg). The results of the research showed that Potassium Silica treatment had a significant effect on flowering age, and the number of fruit per plot, and had a very significant effect on fruit weight per plot. Providing cow manure fertilizer had no significant effect on all parameters. The best fruit weight per plot was obtained in the K0S2 combination, namely 2.13 kg.   Kata kunci : Kalium Silika, Pupuk Kandang, Mentimun.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh pemberian pupuk NPK Pelangi dan pupuk kandang sapi terhadap pertumbuhan serta hasil tanaman kacang panjang (Vigna sinensis L.), serta interaksi antara kedua perlakuan tersebut. Penelitian dilaksanakan di UPTD BI Palawija Tanjung Selamat, Kabupaten Deli Serdang, Sumatera Utara, pada Desember 2024–Februari 2025. Penelitian menggunakan Rancangan Acak Kelompok (RAK) faktorial dua faktor dengan tiga ulangan. Faktor pertama adalah dosis pupuk NPK Pelangi (0 g, 111 g, dan 200 g per tanaman) dan faktor kedua adalah dosis pupuk kandang sapi (0 g, 625 g, dan 1111 g per tanaman). Parameter yang diamati meliputi tinggi tanaman, jumlah daun, umur berbunga, jumlah buah, dan bobot buah per plot. Hasil penelitian menunjukkan bahwa pupuk NPK Pelangi berpengaruh nyata terhadap bobot buah pada umur 49 HST, namun tidak berpengaruh terhadap parameter lain. Pupuk kandang sapi berpengaruh nyata terhadap tinggi tanaman dan jumlah buah, dengan dosis sedang (625 g) paling efektif pada fase vegetatif. Interaksi kedua perlakuan tidak menunjukkan pengaruh signifikan pada seluruh parameter. Hasil penelitian menunjukkan bahwa pemberian pupuk NPK Pelangi dan pupuk kandang sapi dapat meningkatkan pertumbuhan dan hasil tanaman kacang panjang apabila digunakan dalam dosis yang tepat dan sesuai fase pertumbuhan.
