Abstract

The study was conducted to evaluate intercropping forage production between inoculated arbila (Phaseolus lunatus) and sorghum (Sorghum bicolor) at different planting space of arbila and different row number of sorgum. The experiment was arranged factorially according to completely randomised design. The first factor was two planting space of arbila i.e. J1 (120 cm) and J2 (180 cm). The second factor was three different row number of sorghum i.e. P1 (1 row), P2 (2 rows), P3 (3 rows). The replication for each treatment combination was three giving total number of experimental units of 18. Variables abserved were organic matter (OM), crude protein (CP), crude fiber (CF), nitrogen free ekstract (NFE), ether extract (EE), and ash contents of intercropped forage. Results showed that nutritional value of intercropping forage between  arbila and sorgum was better compared with monoculture crop of either arbila or sorghum. At intercropping, OM content of all treatments were high, except for treatment  J1P1. The lowest CF was noticed for treatment J1P2 (30.64%). The highest CP content was for J1P1 (16.16%) but  the CP content of J1P2 was still quiet good (13.36%). EE values were relatively similar for all treatments. The highest value for NFE was for J1P3 (48.35%) and J2P1 (48.45%) but the value for J1P2 was still reasonably good (48.35%). The ash content for treatment J1P1, J1P2, and J1P3 was 8.62%, 7.51%, and 7.15% respectively, and it was considered good enough for forage. In conclusion, intercropping between arbila at 120 cm planting space and 2 or 3 rows of sorghums produces the best nutritive content of forage for ruminant feed.

Abstract

Penelitian bertujuan untuk mengevaluasi perubahan nilai nutrien hijauan sorgum (Sorghum bicolor (L.)Moench) varietas lokal Rote sebagai pakan ternak ruminansia pada umur panen dan dosis urea yang berbeda,telah dilaksanakan di rumah kaca Laboratorium Hijauan Makanan Ternak dan Pastura Fakultas PeternakanUniversitas Gadjah Mada selama 4 bulan dari tanggal 11 November 2011 hingga 27 Februari 2012. Penelitianini dirancang dengan rancangan acak lengkap pola faktorial dengan 2 faktor perlakuan yaitu umur panen (UP)sebagai faktor pertama (UP1= 50 hari, UP2 = 70 hari, dan UP3 = 90 hari) dan dosis pupuk urea (P0 = tanpaurea sebagai kontrol, P1 = 50 kg/ha, dan P2 = 100 kg/ha) sebagai faktor kedua. Kombinasi perlakuan inidiulang 4 kali. Variabel yang diamati adalah kadar bahan organik (BO), protein kasar (PK), serat kasar (SK),ekstrak eter (EE), bahan ekstrak tanpa N, dan kadar abu (%) hijauan sorgum. Hasil penelitian menunjukkan bahwa kadar BO pada UP3P2, UP3P1 dan UP3P0 lebih tinggi dari perlakuan lainnya. Kadar PK tertinggi terdapat pada UP1P2 dan kadar EE tertinggi pada UP3P2. Kadar SK pada UP3P2 dan UP3P0 lebih tinggidan kadar BETN pada UP2P0 dan UP1P1 lebih tinggi dari perlakuan lainnya. UP1P0, UP1P1, dan UP1P2menghasilkan kadar abu yang lebih tinggi dari perlakuan lainnya. Disimpulkan bahwa umur panen 90 hariyang dikombinasikan dengan dosis urea 100 kg/ha menghasilkan nilai nutrien hijauan sorgum terbaik sebagaipakan ruminansia dengan 93,69% kadar BO, 04,45% kadar PK, 08,41% EE, dan 33,14% SK, 47,21% kadarBETN, dan 06,79% kadar abu.
