<div>Background: Rice is the most important and extensively grown food crop in the world in terms of food, area and production. It is a staple food which serves for nearly half of the world&rsquo;s seven billion people (IRRI, 2013). Rice constitutes high percentage of carbs with substantial amount of proteins, fat, fibre, mineral and vitamins.&nbsp; 
 
Methods: Composition and nutritional content of rice varies with varieties and especially processing method. The objective of the present investigation titled &ldquo;Compositional Analysis of Four Varieties of Rice-Cheruvally, Njavara, D1 and Bhadra&rdquo; was to compare the proximate composition and total amylose-amylopectin content of rice cultivars selected. Total Amylose content, amylopectin content and amylose-amylopectin ratio was estimated spectrophotometrically at 620 nm. Among the proximate composition analysis, percentage of carbohydrate, crude protein, ash, moisture and fat were determined using AOAC standard method. 
 
Result: In the present investigation the results of the proximate composition and the amylose content of all the four rice varieties indicated significant difference in all the parameters assessed. It is understood that the rice samples selected for the study belongs to high amylose variety with amylose-amylopectin ratio falling between 0.35-0.45. In summary, the study on the proximate composition and amylose content of rice cultivars has revealed some vital information and these generated results will find their way in determining their suitability in food and other relevant industries.&nbsp;</div>

Background: Rice being staple food has qualities beyond its nutritive value with high digestibility and least allergic properties compared to other cereal grains. Research on exploring the nutritional value of traditional rice varieties with its inherent medicinal values and productivity has poor documentation and hence should be encouraged and supported. Field experiment was conducted with the objective to study the productivity of medicinal rice varieties as influenced by nutrient sources (inorganic and organic) and soil conditions (reduced and oxidized) under direct seeded rice. 
 
Methods: A field experiment was conducted in the wetland during Rabi season (October-February) at Tamil Nadu Agricultural University, Coimbatore with an objective to study the effect of crop establishment of medicinal rice varieties as influenced with nutrient sources and soil conditions under direct seeded rice. The experiment was laid out in factorial randomized block design with three replications. The treatments consisted of soil conditions (reduced, oxidized) as one factor, sources of nutrients (inorganic, organic) as the second factor and four medicinal rice varieties (Black Kavuni, Red Kavuni, Local Kavuni and Njavara) as the third factor. 
 
Result: The reduced condition and inorganic source of nutrient recorded higher plant height, maximum tiller population dry matter production, leaf area index, panicle length, higher number of spikelet panicle-1, 1000-grain weight and filled grains. Among the medicinal rice varieties, Red Kavuni recorded higher growth parameters and yield attributes. From the above results, it could be concluded that Red Kavuni medicinal rice under a reduced condition with inorganic nutrients resulted in higher growth parameters and yield attributes.
