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.
Le riz en Zambie a été traditionnellement cultivé dans des
environnements des plaines inondées ou semi-inondées. Ces
milieux sont malheureusement qu’une petite partie de la Zambie,
qui occupe seulement 1% de la superficie totale. L’augmentation
de la demande alimentaire dans le pays exige que d’autres
milieux de production du riz soient cherchés pour étendre la
culture du riz au-delà des plaines traditionnelles inondées. Cette
étude a donc été mise en place pour examiner plusieurs variétés
de riz de plaine et deux variétés de riz de montagne quant à
leur aptitude de culture dans les conditions de montagne. Deux
sites, Longe et Namushakende ont été utilisés pour l’essai avec
2 milieux (montagne et plaine) choisis à chaque site. Il y avait à
la fois l’effet du milieu et de la variété sur le rendement en
grain. Les variétés de meilleure qualité dans des conditions de
montagne ont été Nerica 1 et Nerica 4. Dans des conditions de
basse altitude, les variétés de plus grand rendement ont été
Supa, Kajakete, Wahiwahi et le riz noir. Il est recommandé que les variétés Nerica de montagne soient explorées
préalablement pour la croissance possible dans des conditions
de montagne zambienne.

Notes:
"The 2010 RUFORUM Biennial Conference was the second in the series. The main objective of the Biennial conferences is to provide a platform for agricultural research for development stakeholders in Africa and beyond to actively exchange findings and experiences, while at the same time learning lessons towards improving performance of the agricultural sector and ultimately people’s livelihoods. The biennial conference is RUFORUM’s most comprehensive meeting for the diversity of stakeholers in agriculture. It is especially dedicated to graduate students and their supervisors, grantees in RUFORUM member universities and alumni. It is a platform for peer review, quality control, mentorship, networking and shared learning. This record contains an extended abstract accepted under the theme of plant breeding".
