Abstract/ Executive Summary:

The experiment was performed in the experimental land of the Institute of Biological Sciences, Rajshahi during the period of April-May, 2007 and 2008. The physical and chemical characteristics of jute fibre under different foliar treatments were investigated at mature stage. The results showed significantly increase in most of the chemical composition under different foliar treatments. Moisture content, dry matter and ash contents of jute fibre obtained from experimental land compared to those of control jute fibre after application of NPK-fertilizers and cowdung in combination with foliar spray. The moister content of jute fibre decreased whereas ash content increased significantly under different treatments. The moisture and ash contents of jute fibre were varied between 12 to 14% and 0.5 to 0.7%, respectively. On the other hand the dry matter content of jute fibre increased slightly under different treatments. The aqueous extract, fatty and waxy matter, pectic matter, α-cellulose, hemicellulose, lignin contents and tensile strength of jute fibre as compared to those of control were as follows: The maximum increase of aqueous extract 20.65% (treatment T₂), the maximum increase of fatty and waxy 22.54% (treatment T₂), pectic matter 5.49% (treatment T₆), α-cellulose 61%, hemicellulose 29%, lignin contents 7.29% (treatment T₆) and tensile strength 15.55%.

Start Date: 00-00-2007

End Date: 00-00-2008

Program Area: Crop-Soil-Water Management

Commodity: Jute

Objectives:

To investigate the effect of NPK-fertilizers, cowdung in combination with foliar spray of urea and chemicals on jute plant and quality of jute fibre.

Methodology:

The experiment was carried out at the experimental land of the Institute of Biological Sciences, Rajshahi University, Bangladesh during the season April-May, 2007 and 2008. The experiment was laid in a Randomized Complete Block Design (RCBD) with 10 treatments and one control. The plot sizes being used were 4x5 m with a walking path between the plots of 0.50 m. The treatments being used denoted as T₁ is control while T₂, T₃, T₄, T₅, T₆, T₇, T₈, T₉, T₁₀ and T₁₁ are the experimental. Before sowing of jute seed, cow-dung and NPK-fertilizers were applied at the ground level. Each plot received cow-dung at the rate of 250 kg ha^-1 and NPK-fertilizers 200 kg ha^-1.

Firstly, after 30 days of sowing foliar spray of 0.1% of urea solution and 0.1% KNO₃ solution were performed on jute leaves in different blocks systematically.

Secondly, after 50 days sowing foliar spray of 0.1% of chemicals were applied on jute leaves. The NPK-fertilizers were applied in the form of urea (N), triple super phosphate (P) and murate of potash (K) in a broad cast method and as chemicals KCl, Ca₃(PO₄)₂ and Na₂HPO₄ were used. The experiment was repeated in two seasons.

After 70 days of sowing matured jute fibres were collected from the experimental research field using the traditional procedures and used for experimental purposes.

The physical properties were determined by the following procedures viz. moisture content and dry matter content (by conventional procedure), ash content.

The data obtained was statistically analyzed by the method of analysis of variance (ANOVA) and the differences due to treatment means were determined using Dancan’s Multiple Range Test (DMRT) by MSTAT programme.
