Abstract
With decreasing the area of productive agricultural land, soilless cultivation is greatly needed to develop healthier vegetables cultivation. This study aimed to determine the effect of the kind of composition of the growing medium and liquid vermicompost dosage on the growth and yield of lettuce (Lactuca sativa L.) which growing hidroganically. This study was a pot experiment using Factorial Randomized Block Design (RBD). The first factor was the kind of media composition consisting of two levels, namely: M1 = cocopeat (55%), zeolite (15%), and sand (30%), M2 = cocopeat (55%), zeolite (30%), sand 0.14 (15%). The second factor was vermicompost dosage consisting of five levels: V1 = 50 g/pot, V2 = 100 g/pot, V3 = 150 g/pot, V4 = 200 g/pot, V5 = 250 g/pot. Each treatment had thre replications with five plants samples. The results showed that the two factors tested did not show significant interaction. Separately, the kinds of media composition did not have a significant effect. While the treatment of vermicompost dosages had a significant effect, where overall the dosage of V4-V5 (200-250 g/pot) gave the highest yield of lettuce. The average fresh weight of total biomass at these doses ranged from 158.92-163.33 g/plant. Keywords: Composition of growing media, Lettuce, Hydroganic, Vermicompost
Highlights
Di zaman yang semakin berkembang serta kemajuan teknologi yang semakin pesat, penggunaan lahan untuk industri semakin meluas sehingga menggeser lahanlahan pertanian, sehingga menambah kepadatan di daerah pinggiran kota dan membuat lahan pertanian semakin berkurang
Faktor 1 adalah Macam Media yang terdiri dari dua taraf yaitu : M1 = cocopeat (55%), zeolite (15%), dan pasir (30%), M2 = cocopeat (55%), zeolite (30%), pasir (15%)
Pemanfaatan mineral zeolit untuk meningkatkan efisiensi pupuk nitrogen dan fosfor
Summary
Berdasarkan hasil analisis ragam pertumbuhan tinggi tanaman menunjukkan bahwa perlakuan pemberian macam komposisi bahan media tanam dan pemberian dosis verimikompos tidak menunjukkan interaksi yang nyata pada tinggi tanaman selada keriting. Rata-Rata tinggi tanaman selada keriting (cm) pada perlakuan macam komposisi media dan dosis pupuk vermikompos cair. Hasil uji BNJ 5% rata-rata tinggi tanaman pada Tabel 1 menunjukkan bahwa M2 (media tanam dengan komposisi 55 % cocopeat, 30 % zeolit dan 15 % pasir) memberikan tinggi tanaman lebih tinggi dari pada M1 (media tanam dengan komposisi 55% cocopeat, 15 % zeolit dan 30% pasir) saat umur 7, 12 dan 17 hari setelah transplanting. Hal ini dikarenakan zeolit dapat mengikat dan menyimpan unsur hara yang diaplikasikan pada media tanam dalam bentuk pupuk vermikompos cair, kemudian dilepaskan kembali saat tanaman membutuhkan. Nurhidayati et al (2017a) menambahkan bahwa vermikompos dengan penambahan bahan aditif tepung cangkang telur dan tepung ikan, mengandung nutrisi yang lengkap
