Yield Evaluation Of Fifteen Rice (Oryza Sativa. L) Genotypes Under Rainfed And Irrigated Conditions In Northern Ghana.

ABSTRACT

This study was undertaken to examine the nature and quantify the magnitude of Genotype by Environment interaction effects on rice (Oryia Sativa L.) grain yield and to determine the most stable and winning genotype (s) in terms of yield stability and performance in two rice producing hubs. The study was conducted at four locations within two rice producing hubs in Northern Ghana on fifteen (15) rice genotypes including a checking genotype GR18 red. A randomized complete block design with three replications was employed. A multi environment trial analysis depicted differential performance of rice genotypes at the different test environments.
