Nutrient Combination With Biochar: Improving Yield and Quality of Jute Seed

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.

Mitigating the Toxic Effects of Chromium on Wheat (Triticum aestivum L.) Seed Germination and Seedling Growth by Using Biochar and Polymer-Modified Biochar in Contaminated Soil

“…Lower Cr VI availability and plant accessibility showed excellent sorption ability of JBCs and JPBCs [22]. In a review study about ameliorating effects of BC on physio-chemical properties of weather soil, Glaser et al [19] found positive effects of BC in immobilizing Cr in soil and lowering plant accessibility. Moreover, lower plant availability of Cr VI as affected by applied JPBCs could be due to the presence of more active and binding sites on JPBCs' surface, which strengthens its ability in fixing heavy metals [24,25].…”

“…Generally, BC produced at high temperature (600-700 • C) has higher aromaticity and recalcitrant potential, but due to dehydration and deoxygenation, has a smaller number of O-and H-containing functional groups [17,18]. Meanwhile, BC produced at low temperature (300-400 • C) has more O-and H-containing functional groups and variety of organic characteristics [19,20]. Herath et al [21] reported a 93-97% decrease in Cr, Ni, and Mn bioaccumulation in tomato plants by the application of BC.…”
