Abstract

Abstract Differential response to Zn of several plant genotypes other than rice ( Oryza sativa L.) has been shown by others. This study was conducted to compare the response to Zn of several foreign and domestic rice cultivars grown under varying fertility and water management conditions in greenhouse pot culture. Reduction in dry matter yields due to Zn deficiency in the several rice cultivars was in the order: ‘Bluebelle’ > ‘Bluebonnet‐50’ > ‘Dawn’ > ‘Nato’ > ‘Calrose.’ The very early maturing variety Bluebelle was less tolerant to low levels of available Zn than the later maturing cultivars, especially Calrose. Differences existed among cultivars with respect to Zn and P uptake, but could not be related to degree of Zn responsiveness. Adaptation to upland soil conditions differed among cultivars although both growth and Zn uptake were always higher under flooded conditions. The cultivar ‘Sinaloa’ from the Dominican Republic responded well to upland conditions whereas Calrose grew poorly. ‘Juma,’ ‘Bluebelle,’ ‘Starbonnet,’ and ‘Chontalpa’ were intermediate.
