Description 660-669
A field experiment was conducted during the Samba season at the Tamil Nadu Agricultural University, Coimbatore wetland farm with the objective of studying surface morphology and growth output of medicinal rice varieties in the western zone of Tamil Nadu under the irrigated rice ecosystem. The experiment was conducted with five replications in a Randomized Block Design (RBD). The treatment consists of three medicinal rice varieties and one high yielding variety of Tamil Nadu viz., Red kavuni, Black Kavuni and Njavara and CO(R)50. The observations were recorded on growth parameters like plant height, tillers, dry matter production and the physiological parameters like Leaf Area Index (LAI), Crop growth rate, Relative growth rate (CGR) and Net assimilation rate (NAR). The yield attributes like productive tillers/m2, total spikelet, filled grains, unfilled grains, thousand grain weight, grain yield and straw yield were recorded at the time of harvest. Physical, cooking, bio chemical parameters like amylose per cent, total phenol content, total protein and β - carotene was also recorded. The surface morphology of the grain and husk shape and appearance were also studied and examined under Scanning Electron Microscope (SEM). The study concludes that among the medicinal rice varieties, Red Kavuni recorded enhanced growth characters, yield attributes, yield (2,391 kg/ha), B:C ratio and optimum cooking quality parameters as compared to Black Kavuni and Njavara. Njavara recorded higher gross return and net return. With respect to nutritive and medicinal properties, Black Kavuni recorded higher phenol content, protein content and β-carotene when compared to other varieties.
