Abstract

The aims of this research were to study vegetative growth of upland rice and some pineapple varieties in intercropping at dryland. The research was conducted from October 2003 until March 2004 at Logandeng village, Playen, Gunung Kidul regency, Yogyakarta province.

The additional treatments consist of upland rice monoculture (P100), intercropping with proportion queen blitar 25%: 75% upland rice (P75) and intercropping with proportion queen blitar 75%: 25% upland rice (P25).
