Produksi kacang panjang (Vigna sinensis L.) dipengaruhi oleh teknik pemupukan dan jenis pupuk yang dipakai. Penggunaan dosis yang tepat serta waktu yang tepat akan memaksimalkan produktivitas buah yang dihasilkan. Penelitian tentang penggunaan pupuk cair limbah tahu dan kotoran kambing terhadap pertumbuhan dan produksi kacang panjang untuk mengetahui efektivitas dosis pupuk dan pengaruhnya masing-masing. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) dengan perlakuan penambahan pupuk organik cair limbah tahu dan kotoran kambing. Faktor pertama adalah pemberian pupuk kendang kambing, yaitu konsentrasi 0 g (PK0), 200 g (PK1), 400 g (PK2), dan 600 g (PK3). Faktor kedua adalah POC air tahu, yaitu konsentrasi 0 ml/l (PC0), 10 ml/l (PC1), 20 ml/l (PC2), dan 30 ml/l (PC3). Hasil pengujian menunjukkan perlakuan terbaik parameter tinggi tanaman dengan dosis PC1 (233,7 cm), parameter jumlah daun perlakuan terbaik pada PC2 (46,66) dan parameter berat buah terbaik pada perlakuan PK2 (465,50 gr). Penggunaan pupuk organik cair limbah tahu dan kotoran kambing efektif memacu pertumbuhan dana produksi kacang panjang.

Dragon fruit plants originating from Central and South America have not been widely cultivated. This plant has only been cultivated intensively in several countries such as: Israel, Colombia, Nicaragua, Vietnam, Thailand, China and Australia. Macroscopic identification showed that the fungi associated with dragon fruit stems had similarities to the colony form of Colletotrichum gloeosporioides sp. Trichoderma is known to have antagonistic abilities against pathogenic fungi. Trichoderma is easily found in soil ecosystems and plant roots. The method in this study is a survey method. Determination of the sample using purposive sampling or Judgmental sampling method, namely purposive sampling is a sampling method that selects objects (vines) that are considered attacked or have symptoms of pathogen attack. Trichoderma sp is also tolerant to stress and able to inactivate pathogenic microbial enzymes. In addition, Trichoderma sp. Able to produce enzymes that hydrolyze pathogenic cell walls which will inhibit the synthesis of pathogenic cell walls and increase their fungicidal activity, as a result of which pathogenic fungi experience a decrease in growth rate.
