Abstract: Twelve diverse genotype of Joha rice comprising ten local germplasm and two improved genotypes were tested for important biochemical traits under organic and inorganic culture. Two different sites of practices used in a randomized block design with three replicates. The analysis of variance shows that the mean squares of all the biochemical character have significant difference among the genotypes in both organic and inorganic culture. The highest coefficient of variation (CV %) was recorded for Chlorophyll b content under organic (9.32%) and inorganic (16.08%) condition. The mean performance of all the genotypes for the biochemical characters revealed that except iron content character all the biochemical characters have higher mean performance for inorganic culture than organic culture. The genetic parameter analysis shows that the iron content was recorded highest in value for both culture conditions. Most of the biochemical character except amylose content and crude protein content shows better response in inorganic condition than organic condition. The characters were shows negatively correlation with the grain yield per plant in both genotypic and phenotypic level. The crude protein character shows significant negative correlation with yield in both organic and inorganic culture. Based on the performance of 12 Joha genotype in inorganic and organic culture, Bokul Joha was found superior for both cultures, which is improved cultivar of aromatic rice. The genotypes Kunkuni Joha, Kali Jeera, Keteki Joha and Local Joha could be investigated for GE interaction over location and years.
