ABSTRAK Penelitian ini dilaksanakan di Kebun Percobaan Balai Penelitian Tanaman Tembakau dan Serat, Karangploso, Malang, mulai bulan Mei sampai dengan Oktober 2001. Penelitian bertujuan untuk memperoleh varietas wijen yang sesuai pada sistem tumpangsari dengan tanaman jarak kepyar. Rancangan percobaan yang digunakan adalah rancangan petak berlajur dengan tiga ulangan. Perlakuan tumpangsari terdiri dari dua faktor. Faktor pertama yaitu varietas tanaman jarak kepyar Asembagus 81 (Asb 81) dan Asembagus 104 (Asb 104). Faktor kedua yaitu varietas wijen Sumberrejo 1 (Sbr 1) dan Sumberrejo 2 (Sbr 2). Pada setiap ulangan juga ditanam varietas monokulturnya. Ukuran petak 6 m x 6 m, jarak tanam untuk tanaman jarak kepyar 2 m x 2 m (satu tanaman per lubang) dan varietas wijen 0,5 m x 0,25 m (satu tanaman per lubang). Hasil penelitian menunjukkan bahwa tanaman wijen varietas Sumberrejo 1 dengan tanaman jarak kepyar varietas Asembagus 104 memberikan hasil 632,55 gram biji wijen per petak dan 637,63 biji jarak per petak. Parameter total hasil relatif (RYT) sistem tumpangsari wijen dengan tanaman jarak kepyar lebih besar dari satu ( > 1) yaitu antara 1,687 sampai dengan 1,787, sehingga sistem tumpangsari tersebut efisien dalam memanfaatkan lahan.

The objective of the study was to find out the variety of sesame which is suitable for intercropping with castor. A strip plot design was used with three replications. The factorial treatment consisted of two factors. The first factor was castor varieties (Asembagus 81 and Asembagus 104). The second factor was sesame varieties (Sumberrejo 1 and Sumberrejo 2). In each replication, castor and sesame varieties were planted as monocultures. The plot size was 6 m x 6 m, castor and sesame plant spacing were 2 m x 2 m and 0,50 m x 0,25 m respectively. The results showed that the intercropping of sesame Sumbererjo 1 variety and castor Asembagus 104 variety produced 632,55 gram sesame seed per plot and 637,63 gram seed castor per plot. The highest relative total yield on intercropping castor and sesame was obtained by Asembagus 104 and Sumberrejo 1 at 1,787 and the lowest relative total yield was obtained by Asembagus 104 and Sumberrejo 2 at 1,687. RYT value of the intercropping system was more than one which is considered as efficient in land use.
