ABSTRAK

Koro pedang (Canavalia enziformis) merupakan salah satu tanaman yang berpotensi menyubstitusi kedelai. Untuk pengembangan koro pedang secara kontinu perlu disediakan benih bermutu melalui teknologi produksi benih. Pemangkasan dan jarak tanam merupakan faktor yang harus diperhatikan. Penelitian lapangan dilakukan di desa Ciherang kabupaten Bogor. Perlakuan berupa jarak tanam 5 taraf dan pemangkasan 2 macam, dengan menggunakan Rancangan Acak Lengkap Teracak. Hasilnya menyatakan bahwa jarak tanam tidak memengaruhi pertumbuhan vegetatif tanaman, mutu fisik, dan fisiologis benih koro, tetapi memengaruhi jumlah biji polong-1, bobot biji petak-1, dan produktivitas-ton

ABSTRACT

Jack bean potentially as a substitute of soybean. Increasing value of jack bean requirement of good quality of seeds. Availabelity of good quality seeds must be supported by teknology of production. Prunning and planting space are factors should be concidered. Field trial was carried out at Ciherang, Bogor. Using randomized block design, two kind of prunning and five level of planting space. Base on the research indicate that planting space did not influence to vegetatief growth and fisicaly also fisiologicaly seeds quality. Planting space influence to several parameter of yield.
