Penampilan Produksi Hijauan Hasil Tumpangsari Arbila (Phaseolus lunatus) Berinokulum Rhizobium dan Sorgum (Sorghum bicolor) pada Jarak Tanam Arbila dan Jumlah Baris Sorgum
Abstrak: The study was
conducted to evaluate the forage production of arbila (Phaseolus lunatus) and
sorghum (Sorghum bicolor) in intercropping grown on different spacing of arbila
and number row of sorghum, and was designed as completely randomized design of
factorial pattern with two factors. The first factor was the spacing of arbila
(J) i.e. J1 (120 cm) and J2 (180 cm). The second factor was row number of
sorghum (P) i.e. P1 (1 row), P2 (2 rows), P3 (3 rows) with 3 replications. The
variables were dry matter (DM) production, organic matter (OM) production,
crude protein (CP) production of forage, and Land Equivalent Ratio (LER). The
results showed that highest DM production at J1P2 and J1P3 (5.33 and 4.53
tons/ha), highest OM production at J1P2 and J1P3 (5.33 and 4.57 tons/ha),
highest CP production at J1P1, J1P2 and J1P3 (0.55, 0.77, and 0.55 tons/ha),
and highest LER at J1P2 and J1P3 (2.53 and 2.38). It can be concluded that the
intercropping arbila and sorghum at planting space of 120 cm with 2 and 3 row
of sorghums between arbilas produces the best forage production as ruminant
feed.
