Adaptability of rice cultivars to different ecologies in western province of Zambia
Abstract

Rice in Zambia has traditionally been grown in lowland flooded
or semi-flooded environments. These environments are
unfortunately only a small portion of Zambia, occupying only
1% of the total land. The increase in food demand in the country
requires that other rice production environments be sought to
expand the cultivation of the crop beyond the traditional flooded
plains. This study was therefore set up to screen several lowland
rice varieties and two upland rice varieties for suitability for
cultivation in upland conditions. Two sites, Longe and
Namushakende were used for the trial with 2 environments
(upland and lowland) chosen at each site. There was both an
environment and variety effect on grain yield. The superior
varieties in upland conditions were Nerica 1 and Nerica 4.
Under lowland conditions the best yielders were Supa, Kajakete,
Wahiwahi and Black rice. It is recommended that the Nerica
upland varieties be explored further for possible cultivation in
upland Zambia conditions.
