Performance evaluation of fourteen rice (Oryza sativa L.) varieties at Gazipur eastern Uttar Pradesh

Abstract

Crop genotypes play a dominant role in crop production systems. They affect crop productivity by their higher yield potentials, resistance against insect pest and diseases under different climatic conditions. A field experiment was conducted at Zonal Agricultural Research Sub Station, (ANDUAT) Ghazipur, during 2018 and 2019 to evaluate the growth, yield and yield attributing characteristics of 14 rice varieties collected from Crop Research Station, Masodha, Ayodhya namely; NDR- 2107-7-1, NDR- 2108-6-1-3-1, NDR- 2109-9-9-5-1, NDR- 2106-14-1, NDR –2110-7-1, NDR- 2111-13-1-6, NDR- 2112-20-1, NDR-2026, NDR -2103, NDR-2113-24-1, NDR-2114-13-1and and three check varieties viz. NDR 2064, NDR 2065 and NDR 359. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replicates. The plot size of the experiment was 10 m x 10 m2. Parameters on, growth parameter viz. plant height, and number of tiller/m2; yield contributing characters such as effective tillers/m2, panicle length, number of grains panicle/panicle, sterility %/panicle, thousand grain weight and grain yield were recorded. The genotypes of NDR 2012-20-1 (57.15 q/ha) followed by NDR 2111-13-1-6 (56.17 q/ha) have high yield stability, while the genotypes of NDR 2026 (48.89 q/ha) followed by NDR 2114-13-1 (49.75 q/ha) have low yield stability. Hence, NDR 2012-20-1 and NDR 2111-13-6-1 could be recommended for cultivation by the farmers in Gazipur and these cultivars should be popularized in larger scale to make use of its superiority.
