Abstract:
A field experiment was conducted to evaluate the yield and yield attributing characteristics of 12 upland red rice cultivars collected from various hilly districts of Manipur. The experiment was laid out in a Randomized Block Design with three replicates. The experimental field's soil was silty clay loam in texture, acidic in reaction (pH 3.9), low in available nitrogen (237.96 N kg/ha) and available phosphorus (14.80 P2O5 kg/ha), medium in available potassium (263.66 K2O kg/ha) and high in organic carbon (1%). Parameters on yield contributing characters such as panicle length, panicle weight, number of filled grains/panicle, thousand grain weight and grain yield were recorded. All of the parameters of yield and yield contributing characters differed significantly at 5% level. Cultivar Tabnangsang exhibited the longest panicle (30.08 cm), while Bujaro had the shortest (23.21 cm). The heaviest panicle was observed in Taneng kahengbo (6.13 g), and the lightest in Chadae (3.08 g). Cha neng had the highest number of filled grains per panicle (110.14), while Picharo had the lowest (67.11). The highest thousand grain weight was in Angah (32.08 g), and the lowest in Shantan naphaeng (16.87 g). The cultivar Chatee had the highest grain yield (26.75 q/ha), followed by Taneng kahengbo (25.93 q/ha). According to these findings, farmers are advised to grow these particular upland red rice cultivars in order to achieve optimal yield and also benefit from the various health advantages associated with red rice consumption.
