Study on physiological growth parameters, yield and yield contributing traits in aromatic and non-aromatic rice (Oryza sativa L.) genotypes

Abstract

An experiment was conducted to study on physiological functions, yield and yield contributing traits in aromatic and non-aromatic rice genotypes during kharif, 2017 & 2018. Results showed that maximum LAI, AGR, LAD and LAR were recorded in aromatic rice, Belgaum Basmati, Paras Sona and Phule Maval and in non-aromatic rice Karjat-9. Highest dry matter production recorded for the variety Karjat-3 (non-aromatic), while lowest dry matter was recorded in genotype Girga (aromatic). Highest grain yield was recorded in Karjat-3 and lowest grain yield was recorded in Girga. The aromatic and non-aromatic rice genotypes differed significantly with respect to yield components like leaf area index, leaf area duration, leaf area ratio, total number of filled spikelets, grain yield and harvest index.
