Pertumbuhan dan hasil kacang hijau kultivar Kenari dan No. 12 dalam tumpangsari bersisipan di antara padi gogo ( Growth and yield of Kenari and No. 129 mungbcan cultivars on relay intercropping between of upland rice)

Penelitian ini bertujuan untuk mendapat¬kan waktu penyisipan dua kultivar kacang hijau dalam tumpangsari bersisipan yang terbaik di antara padi gogo terhadap pertumbunan dan hasil kacanghijau, Percobaan dilaksanakan dari bulan Desember 2010. Sampai Juli 2011 di kebun percobaan Ciparanje Fakultas Pertanian Univer¬sitas Padjadjaran, jatinangor, Sumedang. Perco¬baan ditata dalam Rancangan Acak Kelompok (RAK) dengan tiga ulangan yang terdiri atas 10 perlakuan yaitu A25 = kultivar Kenari + Waktu Penyisipan 25 hari sebelum panen padi gogo. A20 = kultivar Kenari + waktu penyisipan 20 hari sebelum panen padi gogo, A15 = kultivar Kenari + waktu penyisipan 15 hari sebelum panen padi gogo, A10 = kultivar Kenari. waktu penyisipan 10 hari sebelum panen gogo, A5= kultivar Kenari + waktu penyisipan 5 hari sebelum panen gogo, B25 = kultivar No. 129 + waktu penyisipan 25 hari sebelum panen padi gogo, B20 = kultivar No. 129 + waktu penyisipan 20 hari sebelum panen padi gogo, B15 = kultivar No.129 + waktu penyisipan 15 hari sebelum panen padi gogo,B10 =kultivar No. 129 + waktu penyisipan 10 hari sebelum panen padi gogo, B5= kultivar No. 129 + waktu penvisipan 5 hari sebelum panen padi gogo. Hasil penelitian menunjukkan waktu penyisipan kacang hijau di antara padi gogo dengan kisaran 25; 20, dan 15 hari sebelum panen padi gogo, mernberikan pertumbuhan dan basil kedua kultivar Kenari dan No. 129 lebih baik dibandingkan perlakuan 5 dan 10 hari sebelum panen padi gogo, dan menghasilkan nisbah kesetaraan lahan dengan besaran masing-masing kultivar 1,77; 1,53, 1,27 dan 1,77;1,53 dan 1,63.

The objectives of this experiment wag to find the best the timing insertion of two mungbean cultivars on relay intercroppng between of upland rice on growth and yield. The experiment was conducted from December 2010 to July 2011 in Ciparanje research station of Agriculture Faculty, Universitas Padjadjaran, Jatinangor Sumedang. A randomized block design used was with three replications and ten Lreaimens. Those ten treatments consisted of A25 Kenari cultivar + timing of insertion on 25 days before harvesting upland rice, A20 — Kenari cultivar i timing of insertion on 20 days before harvesting upland rice, A15 = Kenari cultivar + timing of insertion on 15 days before harvesting upland rice, A10 = Kenari cultivar + timing of insertion on 10 days before harvesting upland rice, AS — Kenari cultivar + Liming of insertion on 5 days before harvesting upland rice, 1325 = No.129 cultivar I- timing of insertion on 25 days before harvesting upland rice, 1320 = No. 129 cultivar + timing of insertion on 20 days before harvesting upland rice, B15 — No.129 cultivar + timing of insertion on 15 clays before harvesting upland rice. 1310 — NO. 129 cultivar + timing of insertion on 10 days before harvesting upland rice, B5 = No. 129 cultivar + timing of insertion on 5 days before harvesting upland rice. The result showed that the timing of insertion of munghean between of upland rice with a range on 25, 20 and 15 days before harvesting upland rice gave the better growth and yield of two mongbean cultivars Kenari and No. 129 compared to another timing of insertion, whereas there two cultivars with timing of insertion on 25, 20 and 15 days before harvesting upland have higher competitive ratio and produced land equivalent ratio for each cultivar i.e 1.77; L53; 1.27 and 1.77; 1.53 and 1.63.
