Performance studies on jute genotypes (Corchorus olitorius L.) for screening fibre yield components and biotic stress factors under terai region of Province -1 Nepal

Abstract

The present study was conducted to know the performance of growth, yield contributing parameters and stress tolerance factors of tossa jute genotypes at the farm of Jute Research Program, Itahari, Sunsari, Nepal during 2017 and 2018. A total of 11 tossa jute genotypes were sown in Randomized Block Design (RBD) with three replications. Among the genotypes, JRO-524 produces highest plant height (322.97 cm), green fibre yields (17.26 t ha^-1), green stick yields (17.97 t ha^-1), dry fibre yields (2.73 t ha^-1), dry sticks yield (6.31 t ha^-1), whereas, genotypes SRP-7016 produces highest green plant yield (51.18 t ha^-1) followed by JRO-524 (48.73 t ha^-1). Respective of biotic stress factor, the genotype JRO-524 was found to be less susceptible against Bihar hairy caterpillar (5.68%), semilooper (5.25%) andmites (2.53 mites leaf^-1). The genotype JRO-524 gave understanding superiority on growth, yield and yield contributing traits, and biotic stress tolerance.
