      Abstract
      Penelitian ini bertujuan untuk mengetahui respon pertumbuhan dan hasil kangkung terhadap pemupukan kascing dan bioboost beserta residu keduanya. Penelitian ini menggunakan Rancangan Kelompok Lengkap Teracak Faktorial. Faktor pertama adalah pemupukan kascing (K) dan residunya (RK), yaitu tanpa kascing (K0 dan RK0), kascing 300 g per lubang tanam (K1 dan RK1), dan kascing 450 g per lubang tanam (K2 dan RK2). Faktor kedua adalah pemupukan bioboost (B) dan residunya (RB), yaitu tanpa bioboost (B0 dan RB0), 2 l /ha (B1 dan RB1), 4 l/ha (B2 dan RB2), dan 6l/ha (B3 dan RB3). Kedua faktor diuji terhadap kontrol negatif (tanpa pemupukan) dan kontrol positif (pemupukan anorganik susulan) setiap perlakuan diulang sebanyak tiga kali sehingga seluruhnya terdapat 39 satuan percobaan dengan luas masing-masing petakan 1,5 m2. Penanaman dilakukan sebanyak dua kali. Penanaman kedua dimaksudkan untuk mengamati residual effect kedua faktor. Hasil penelitian ini menunjukkan kangkung terbaik terdapat pada interaksi 450 g kascing per lubang tanam dan 6 liter bioboost per hektar dengan potensi hasil mencapai 23,67 ton per hektar pada penanaman pertama dan 17,73 ton per hektar pada penanaman kedua yang memanfaatkan residu pemberian kascing dan bioboost sehingga tidak perlu melakukan pemupukan pada penanaman kedua.
       
      This study aims to determine the growth response and yield of kangkong to vermicompost and bioboost fertilization and their residues. This study used a Factorial Randomized Complete Group Design. The first factor was fertilization with vermicompost (K) and its residue (RK), ie without vermicompost (K0 and RK0), 300 g vermicompost per planting hole (K1 and RK1), and 450 g vermicompost per planting hole (K2 and RK2). The second factor was fertilization with bioboost (B) and residue (RB), namely without bioboost (B0 and RB0), 2 l/ha (B1 and RB1), 4 l/ha (B2 and RB2), and 6 l/ha (B3 and RB2). RB3). Both factors were tested against negative control (without fertilization) and positive control (follow-up inorganic fertilization). Each treatment was repeated three times so that in total there were 39 experimental units with an area of 1,5 m2 each. Planting was carried out twice. The second planting is intended to observe the residual effect of the two factors. The results of this study showed that the best kangkong was found in the interaction of 450 g of vermicompost per planting hole and 6 liters of bioboost per hectare with a potential yield of 23, 67 tonnes per hectare in the first planting and 17,73 tonnes per hectare in the second planting using residues of vermicompost and bioboost so there is no need to fertilize the second planting.
