A field study was conducted at Tamil Nadu Agricultural University, Coimbatore in wetland during samba season 2014-15 with an objective to study the growth performance of rice landraces under irrigated rice ecosystem. The field trail was laid out in Randomized Block Design (RBD) with three replications. The experiment consisted of eight rice landraces and one high yielding variety viz., Chandikar, Kuliyadichan, Kuruvaikalanjiyam, Norungan, Nootripathu, Black Kavuni, Red Kavuni, Njavara and CO(R) 50. Biometric observations were recorded on growth parameters viz; plant height, tiller numbers, dry matter production and leaf area index (LAI) and the physiological parameters like crop growth rate (CGR) and relative growth rate (RGR). The yield attributes like productive tillers, total spikelet, filled grains, unfilled grains, spikelet sterility percentage, thousand grain weight, grain yield and straw yield were recorded at the time of harvest. Nutritional content like protein content, iron content and zinc content were recorded. The plant nutrient uptake and nutrient status in soil was also estimated. From the field study it was concluded that Red Kavuni rice landrace variety recorded enhanced growth characters, yield attributes and nutrient uptake compared to other rice landraces experimented.
