Abstract

Plants are naturally growing on the soil without hampering the eco-friendly environment. Intensive cultivation of crops with high yielding verities (HYV) hampering the soil health resulting unfertile soil. In addition, frequent uses of chemicals as well as overdose of synthetic fertilizer creating hazardous environment for the living things. However, to meet up the demand of foods as well as other basic requirements of increasing population of the world crop cultivation techniques need to be modernized. To overcome this situation, application of organic fertilizer need to apply regularly. Biochar can be a good source of organic fertilizer and it is currently using to improve the soil health globally. To examine the effect of biochar on jute growth and yield an experiment was set up in two different locations (Jute Agriculture Experimental Station (JAES), Manikganj, and Jute Research Sub Station (JRSS), Jashore of Bangladesh) during the period from August to December, 2019. Results revealed that location (JAES) had significant and positive effect on jute physiology and seed yield and as well as seed quality. Among fourteen treatments, treatment T2 (Recommended dose of fertilizer (RDF)) showed the highest plant height (163.5 cm), base diameter (7.44 mm) and pod per plant (16.5) compare to the rest treatments. Treatment T6 (RDF 75% + 25%biochar@3.0tonha-1) showed the best seed weight (2.13 g) and seed yield/ plant (3.98 g) among all treatments. Interaction among treatments and locations, T2 x L2 affected seed germination (99%) and field emergence (92.33%) positively. From this research it was cleared that biochar alone may not enough but combination is required for improving jute seed yield and quality.

The highest plant height (274.74 cm) and base diameter (9.08) was recorded in Jute Agriculture Experimental Station (JAES), Manikganj whereas the lowest was recorded in Jute Research Sub-Station (JRSS), Jashore

Summary

Introduction

Jute (Corchorus spp.) belonging to the family Malvaceae, is one of the important fibre and cash crops of Bangladesh (Islam and Ali, 2017). In agricultural sector of Bangladesh, jute is called golden fibre because of earning foreign currency to strong the national GDP (Anonymous, 2013). Jute covers around 80% of bast fibre production world-wide (FAO, 2014). Jute fiber is well known for its versability, durability and fitness and fiber is used for making different type of products including carpet, mat and cloths (Zhang et al, 2013). Young leaves of jute are popular as vegetables because of containing several proteins, vitamins, minerals and antioxidants (Islam, 2007; Mollah et al, 2020; Tareq et al, 2019). Study showed that jute plant has significant importance for pharmacological research as it contained several secondary metabolites important for human health issues (Al-Snafi, 2016)
