Abstract

Fungi of different kinds/races have been observed on Tossa jute seeds collected from different locations in Bangladesh. These fungi harm the quality of seeds and lessen germination percentage of the seeds. The aim of this research was to determine the seed-borne fungal pathogens on Tossa jute varieties collected from different locations in Bangladesh. The experiments were conducted following Completely Randomized Design (CRD) with four replications. Eight Tossa jute varieties are used in the present research. Seed sample of each and every variety collected from each of four different districts of Bangladesh. The predominant identified fungi were Macrophomina phaseolina, Botryodiplodia theobromae, Aspergillus spp., Fusarium spp. and Penicillum spp. Kishoregonj District as well as O-72 variety is the most vulnerable in response of seed borne fungal infection, individually and simultaneously. Rangpur District as well as O-795 variety is the most secure in response of seed borne fungal infection, individually and simultaneously. No limitation has been found to conduct the experiment. Seed borne fungal pathogens are the extreme constraints which deadly influenced the healthy Tossa jute seed production. From the results obtained from this study, it will be easy to select the right variety and location for Tossa jute seed production in Bangladesh. And Farmers can be careful at the beginning of Tossa jute seed cultivation to get rid of the fungus which is more prevalent.

Highlights

Tossa jute, (Corchorus olitorius), called Jute mallow, nalta jute, or jew’s mallow, annual herbaceous plant belongs to the mallow family (Malvaceae), mainly cultivated as like a source of jute fibre
The incidence of fungi was observed the maximum at the seed sample collected Kishoregonj district
Results of this study revealed that the Tossa jute seeds produced in experimental plot or by farmers are very recurrently infected by seed borne fungi

Summary

Introduction

Tossa jute, (Corchorus olitorius), called Jute mallow, nalta jute, or jew’s mallow, annual herbaceous plant belongs to the mallow family (Malvaceae), mainly cultivated as like a source of jute fibre (natural bast fibre). Its juvenile stems and mucilaginous leaves are frequently eaten as a vegetable [1]. It is mostly grown in the tropical and South-East Asian countries in Bangladesh and India. The fibre of jute produced in Bangladesh is frequently deliberated the best quality fibre in the world. Jute is recognized the "golden fiber" for its bright color as well as high cash value. The jute fibre comes from the ribbon (outer skin of main stem) of the jute plant. Bangladesh supplies about 70% jute and related product to the global market [3]. About 84% of world production of jute fibre is obtained in Bangladesh and India collectively [5]. Total area under jute crop production has been anticipated at 7, 79, 658 hectares and total jute crop
