Abstract/ Executive Summary:

Two different types of hessian fabrics (sized and desized) were treated with unripe natural fruit juice (Botanical Name: Diospyros embrypteris Pers) and copper sulphate solution. The physico-chemical properties of the treated fabrics were determined and made nursery pots for seedling to improve the longevity of rot-proof nursery pot. It was observed that 5% copper sulphate solution treated nursery pots possess longevity 5.5 months but the extract of natural fruit juice mixed with 5% copper sulphate solution treated sample increases the longevity of nursery pot about eleven months. At the same time 8% copper sulphate solution treated nursery pots longevity more than nine months but natural fruit juice mixed with 8% copper sulphate solution treated nursery pot is required to achieve longevity about fourteen months. Uses of natural fruit gaab have no critical steps to environment, free from health hazard and durable. That's why it has some potentiality to use for making nursery pots with less chemical materials.

Objectives:

The present work has been taken to use natural material (gaab) as a rot-proofing agent and decrease the uses of chemicals, to save our environment from the pollution.

Methodology:

Sized: The specification of the gray hessian was 13 ends/inch, 12 picks/inch and 19 oz/yd2 . 4 sample specimens of 16 inch width and 5 meter length were prepared form the above grey hessian for sized samples. Desized: Desized sample was prepared by treating sized sample with 2-gm/lit diastage at temperature of 50-60ºC for 45 minutes [6]. 4 sample specimens of 16 inch width and 5 meter length were prepared from desized sample. 2.3 Natural unripe fruit juice: Natural fruit was collected from local market. Bengali Name: Gaab Scientific Name: Diospyros embrypteris Pers [5] Ingredients: Fruit (fresh) 2.4 Extraction of Natural fruit juice: (a) 1 kg of fresh fruit was taken and chopped into small pieces. (b) Water was taken (5 litres) and heated upto 45°C. (c) The chopped pieces of fruit was added to the heated water and stirred it well. (d) The solution was boiled for 2 hours till the solution become approximately 1 litre. (e) Then the solution was cooled and filtered. 2.4 Chemical: a) Commercial grade copper sulphate (CuSO₄) b) Soda ash (Na₂CO₃) c) Diastage 2.5 Machine: Mini padding Machine Tensile Strength Tester, Good Brand and Co. Ltd (UK). 2.6 Experimental Procedure: Five different types of solutions were prepared for treatment. These area) Natural fruit (Gaab) juice b) 5% (CuSO₄) solution + 2 % Na₂CO₃ c) 5 % (CuSO₄) solution + 2 % Na₂CO₃ + Natural fruit solution (Gaab) d) 8% (CuSO₄) solution + 3 % Na₂CO₃) 8 % (CuSO₄) solution + 3 % Na₂CO₃+ Natural fruit solution (Gaab) The samples were made in a padding machine at the speed of 2 m/min under 2 bar pressure and finally the fabrics were dried in the sunlight. 2.6.1 Determination of tensile strength: The tensile strength of the control and treated samples were determined by standard method. 2.6.2 Copper content determination: The copper content of the treated samples were determined by Iodometric method [8] and the results were summarized in Table 1 and 2. 2.6.3 Preparation of nursery pots: Sixty nursery pots were prepared from two different types of fabrics. The size of each nursery pot was 6 "× 7 ". 2.6.4 Preparation of compost: The compost was prepared by mixing equal ratio of cow dung and soil.

Achievement/Findings:

21st century’s slogan is, “Save the Environment.” The utilization of our natural resources will be the key factor for environmental chemical pollution. The present target is to utilize our natural resources and decrease the uses of chemicals. So, natural fruit juice and lower percentage of copper sulphate solution was used as a rot-proofing agent for optimize the longevity of nursery pot.
