Abstract

Selada (Lactuca sativa L.) merupakan salah satu tanaman yang cocok untuk dibudidayakan dengan metode aeroponik vertical horizontal, karena kebutuhan terhadap kondisi lingkungan yang terkontrol jika dibudidayakan pada dataran rendah. Arah penanaman dalam budidaya selada dengan sistem aeroponik vertical memiliki peran penting, arah penanaman yang tidak tepat dapat menyebabkan penyebaran cahaya matahari yang tidak merata sehingga dapat menurunkan laju dan hasil fotosintesis. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh arah penanaman yang terbaik pada pertumbuhan dan hasil tanaman selada yang dibudidaya secara aeroponik vertical heksagonal. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) non factorial dengan perlakuan 6 arah penanaman (A) yaitu: A1 (Arah Barat), A2 (Arah Barat Laut), A3 (Arah Timur Laut) A4 (Arah Timur), A5 (Arah Tenggara), dan A6 (Arah Barat Daya). Hasil penelitian menunjukkan bahwa arah penanaman berpengaruh nyata terhadap pertumbuhan dan hasil tanaman selada pada sistem aeroponik vertikal heksagonal. Arah penanaman A4 (arah timur) memiliki nilai rata-rata tertinggi pada parameter jumlah daun, lebar tajuk, dan berat segar, namun tidak berbeda nyata pada parameter panjang akar dan berat kering. Perlakuan arah penanaman A4 (arah timur) memberikan pengaruh terbaik terhadap berat segar tanaman selada dengan peningkatan sebesar 7,69% dibanding dengan perlakuan A1 (arah barat).

Abstract

Organic fertilizers, such as earthworm fertilizer, and adjusting planting distances to meet plant demands can boost kale plant yields, particularly curly kale. The purpose of this study was to determine the effect of organic fertilizer dosage and planting distance on the growth and yield of kale (Brassica oleracea L. var. Acephala). The research method used a Split Plot Design approach involving two main treatment factors. The results found that the combination of 9 tons/ha (2.16 kg) of manure and a planting distance of 40 x 40 cm produced the best results for crown diameter. The combination of 6 tons/ha (1.44 kg) of manure and a planting distance of 20 x 40 cm gave the best results for fresh root weight per plant at harvest. All criteria were not significantly affected by the use of manure. The treatment of a planting distance of 30 x 40 cm gave the best results for plant height, which was 31.96 cm. Regarding the findings of this study, further researchers can conduct soil analysis before administering the manure coat and re-analyze it after 1 month of administration to determine the quality of the fertilizer content and pay attention to the balance of planting distance for plants, so as to prevent the emergence of diseases caused by high humidity and nutrient competition between plants. Fertilization can also be given to increase yields. The conclusion is that the administration of organic fertilizer doses and planting distances affect the growth and yield of Water Spinach (Brassica oleracea L. var. Acephala).
