Abstract

This research aims to determine the growth response of purple eggplant (Solanum melongena L) plants given NPK 16:16:16 fertilizer and cow manure. This research is located at the UPMI Research Land, Jl. Pasar 12 Marindal II Village Hall, Patumbak District, Deli Serdang Regency, from May 2023 to June 2023. This research used a factorial randomized block design (RAK) consisting of two factors. The first factor is the dose of cow manure fertilizer, and the second factor is NPK 16:16:16 fertilizer. The research results showed that 2 kg/plant cow manure had a significant effect on plant height parameters at 28 HST (25.37 cm). NPK 16:16:16 100 g/plant fertilizer affected plant height parameters at 28 HST (24.59 cm). There is an interaction between the combination of cow manure and NPK 16:16:16 fertilizer, with the best combination of NPK 50 g/plant and cow manure 0 g/plant at plant height parameters of 28 HST (26.11 cm). Key-words: Cow Manure, Eggplant, NPK 16:16:16 Fertilizer INTISARI Penelitian ini bertujuan untuk mengetahui respon pertumbuhan tanaman terung Ungu (Solanum melongena L) yang diberi pupuk NPK 16:16:16 dan pupuk kandang sapi. Penelitian ini berlokasi di Lahan Penelitian UPMI Jl. Balai Desa Pasar 12 Marindal II, Kecamatan Patumbak, Kabupaten Deli Serdang pada bulan Mei 2023 sampai dengan Juni 2023. Penelitianini menggunakan rancangan acak kelompok (RAK) faktorial yang terdiri dari dua faktor. Faktor pertama adalah dosis pupuk Kandang Sapi dan faktor kedua adalah pupuk NPK 16:16:16. Hasil penelitian menunjukkan bahwa pupuk Kandang sapi 2 Kg/tanaman berpengaruh nyata terhadap parameter tinggi tanaman 28 HST (25,37 cm). Pupuk NPK 16:16:16 100 g/tanaman mempengaruhi parameter tinggi tanaman 28 HST (24,59 cm). Terdapat interaksi antara kombinasi pupuk pupuk kandang sapi dan pupuk NPK 16:16:16 dengan kombinasi terbaik NPK 50 g/tanaman dan pupuk kandang sapi 0 g/tanaman pada parameter tinggi tanaman 28 HST (26,11 cm).  Kata kunci: Pupuk Kandang Sapi, Pupuk NPK 16:16:16, Terung

Abstract

Pakcoy (Brassica rapa L.) is a leafy vegetable with high nutritional value widely consumed in Indonesia. However, its productivity in the field is often limited by inadequate macro and micronutrient availability in the soil. Balanced fertilization using both organic and inorganic sources is crucial to support optimal growth and yield. This study aimed to determine the effects of chicken manure and NPK 20-20-20 fertilizer, both individually and in combination, on the growth and yield of pakcoy plants. The research was conducted over two months (June–August) at the experimental field of the University of Community Development using a factorial Randomized Complete Block Design (RCBD) with two factors: chicken manure (0, 1, 2, and 3 kg/plot) and NPK 20-20-20 fertilizer (0, 15, 20, and 25 g/plot), each with three replications. Observed parameters included plant height, number of leaves, shoot fresh weight, and root length. The results showed that chicken manure significantly affected plant height (weeks 1 and 4) and shoot fresh weight. The K2 treatment (2 kg/plot) produced the highest results with a plant height of 41.2 cm and a fresh weight of 118.1 g. NPK fertilizer alone had limited effect, but N1 (15 g/plot) yielded the longest root (28.9 cm) and the highest shoot fresh weight (128.5 g). The interaction between the two fertilizers was significant, with the K2N1 combination producing the highest shoot weight (203.0 g), and K1N1 yielding the longest root (40.1 cm). In conclusion, the combination of 2 kg/plot chicken manure and 15 g/plot NPK fertilizer is the most effective treatment to enhance pakcoy growth and yield. Moderate doses of organic and inorganic fertilizers are proven to support sustainable pakcoy cultivation. Keywords: chicken manure, growth, NPK 20-20-20, pakcoy, yield
