An on-station experiment entitled “Performance of Spring Rice Cultivars against Sowing Dates at Western Terai, Nepal” was conducted at the agronomy farm of Paklihawa Campus from January to July 2022. The trial was set up in a split-plot design consisting of three sowing dates: (January 30 (early), February 15 (mid), and March 1 (late)) as the main factor and four varieties (Hardinath-1, Black Rice Coarse, Chaite-5 & Black Rice Fine) as sub-factor, each replicated three times. Plant height was higher on the late sowing in the Chaite-5 cultivar at 60, 90, and 120 DAS. The number of tillers wasn’t significantly different among the sowing dates, however, a significantly higher value was recorded in Hardinath-1 at 60 DAS, Black Fine at 90 DAS, and Black coarse at 120 DAS. Early sowing dates and cultivars Chaite-5 and Black Fine had a longer duration for flowering and maturity. The yield and yield attributing parameters (panicle length, weight per panicle, spikelet per panicle, and biological yield) were recorded higher in late sowing in the Chaite-5 cultivar. However, grain filling wasn’t observed due to biotic stresses like insect and bird pest infestation. Future research and policy formulation about spring rice should emphasize the management of insect and bird pests.
