Daftar Isi:
- The study aims to evaluate the response sweet potato clones by pruning to tuber production and silage making experiments. In the field using Split Plot design with 3 replays. Sweet potato clones are placed as plots and pruning periods as the main plot. V1: Kuningan Putih, V2: Beta-2, V3: Kuningan Merah, V4: BIS-OP-61, V5: 73-OP-5, V6: BIS-OP-61-♀-29, V7: BIS-OP-61-OP-22. The clone sweet potato consists of trimming period ages 90 dap, 120 dap and 150 dap. The result of trimming stroge is then preserved in the form of silage. Silage making as follows: each clons was cut to a size of 3-5 cm, then used to lower the moisture content. Storage is cut, weighed and added tubers according to treatment is: S1= 100% storage, S2 = 90% storage + 10% tubers, S3= 80% storage + 20% tubers, S4 = 70% storage + 30% tubers. The nutritional value composition of sweet potato silage has of DM 7.07-23.33%, OM 78.04-91.45%, ash 8.57-21.96%, CP 6.90-16.14%,and CF 17.87-57.57% based on dry materials. The value of sweet potato silage of DMD 42.36-63.71%, OMD 38.85-63.64% and TDN 33.24-56.54%.
- Penelitian bertujuan mengevaluasi respon klon ubijalar dengan pemangkasan terhadap produksi umbi dan percobaan pembuatan silase. Di lapang menggunakan rancangan Split Plot dengan 3 ulangan. Klon ubijalar sebagai anak petak dan periode pemangkasan sebagai petak utama. Klon ubijalar terdiri dari: V1: Kuningan Putih, V2: Beta-2, V3: Kuningan Merah, V4: BIS-OP-61, V5: 73-OP-5, V6: BIS-OP-61-♀-29, V7: BIS-OP-61-OP-22. Periode pemangkasan umur 90 hst, 120 hst dan 150 hst. Hasil pemangkasan brangkasan ubijalar kemudian diawetkan dalam bentuk silase. Pembuatan silase sebagai berikut : brangkasan masing-masing klon dipotong berukuran 3-5 cm, dilayukan untuk menurunkan kadar air. Brangkasan dipotong, ditimbang dan ditambahkan umbi sesuai perlakuan, adalah: S1 = 100% brangkasan ubijalar, S2 = 90% brangkasan ubijalar + 10% umbi, S3 = 80% brangkasan ubijalar + 20% umbi, S4 = 70% brangkasan ubijalar + 30% umbi. Komposisi nilai nutrisi silase brangkasan ubijalar mempunyai kisaran kandungan BK antara 7.07-23.33%, BO 78.04-91.45%, abu 8.57-21.96%, PK 6.90-16.14%, dan SK 17.87-57.57% berdasarkan bahan kering. Nilai Kecernaan silase mempunyai kisaran kecernaan BK 42.36-63.71%, Kecernaan BO 38.85-63.64% dan TDN 33.24-56.54%.
