Budidaya tanpa tanah pada dekade terakhir ini semakin berkembang seiring dengan munculnya beberapa permasalahan budidaya tanaman konvensional di lahan pertanian. Tujuan penelitian ini adalah menguji pengaruh aplikasi vermikompos padat dan cair terhadap pertumbuhan, kandungan hara, dan hasil tanaman selada hijau dengan jumlah tanaman per pot yang berbeda. Penelitian ini merupakan percobaan pot di rumah plastik yang menggunakan kultur substrat campuran cocopeat, zeolit, pasir dan vermikompos sebagai sumber nutrisi. Percobaan ini menggunakan Rancangan Acak Kelompok Faktorial. Faktor I adalah macam aplikasi vermikompos (padat, padat+cair,dan cair) dan Faktor II adalah jumlah tanaman per pot (satu, dua, dan tiga tanaman per pot). Hasil penelitian menunjukkan bahwa aplikasi vermikompos padat memberikan pertumbuhan tinggi tanaman (22,73 cm), jumlah daun (8,81), dan luas daun tanaman (974,76 cm2) tertinggi. Kandungan hara tertinggi terdapat pada aplikasi vermikompos padat dengan rata-rata masing-masing sebesar N= 4,39%, P=0,77% dan K=9,07%. Penanaman tiga tanaman per pot cenderung memberikan kandungan hara terendah pada ketiga metode aplikasi vermikompos. Namun, bobot segar biomassa dan hasil ekonomis tertinggi diperoleh pada aplikasi vermikompos padat dengan tiga tanaman per pot masing-masing sebesar 122,22 g dan 111,77 g. Hasil ini menunjukkan bahwa aplikasi vermikompos padat dan tiga tanaman per pot dapat disarankan untuk budidaya tanpa tanah tanaman selada hijau.KeywordsVermikompos; Pertumbuhan; Serapan hara; Hasil tanaman seladaAbstractThis study was a pot experiment in a plastic house using substrates culture and vermicompost as a source of plant nutrients. The purpose of this study was to test the effect of the application of vermicompost on growth, nutrient content and yield of green lettuce with different number of plants per pot. This experiment used a factorial randomized block design. The first factor was kinds of vermicompost application. The second factor was number of plant per pot. The research results showed that the application of solid vermicompost had the highest growth and nutrient uptake in plant height (22.73 cm), number of leaves (8.81) and leaf area (974.76 cm2) as well as an average of N = 4.39%, P = 0.77% and K = 9.07%. The treatments of solid+liquid vermicompost and liquid vermicompost alone, three plants per pot tend to provide the lowest nutrient uptake. However, the highest fresh weight of biomass and marketable yield was obtained in the application of solid vermicompost with three plants per pot by 122.22g and 111.77g, respectively. These results suggest that the application of solid vermicompost and three plants per pot is recommended in soilless culture for green lettuce plants.
