Abstract/ Executive Summary:

A study was conducted during the year of 2017-18 to find out the characterization and utilization of different crop residues/agro-industrial wastes. Crop residues are collected from rice, wheat, maize, ground nut, soybean, sugarcane and coconut field. Agro-industrial wastes were collected from rice mill, wheat and maize flour mill, sugar mill, rice bran oil and coconut oil mill. Collected crop residue/wastes are analyzed for moisture, ash content, volatile matter content, fixed carbon content, bulk density, calorific value, carbon and nitrogen content. Crop residues/agro-industrial wastes under study were characterized by high moisture and high volatile matter content, low ash and low fixed carbon content, low bulk density, irregular shape and low energy content. Present use of crop residues/agro-industrial wastes were livestock feed, fish feed, fuel, mulching materials, soil conditioner, bedding material for animal etc. These wastes can be used for particle board, hard board, show piece for decoration and other household appliances, compost, bio gas, gasification, incineration etc.

Start Date: 00-00-2017

End Date: 00-00-2018

Program Area: Crop-Soil-Water Management

Commodity: Fertilizer

Objectives:

To find out the characterization and utilization of crop residue/agro-industrial wastes generated from different crops/agro-industries

Methodology:

A study was conducted during the year of 2017-2018 to find out the characterization and utilization of different crop residues/agro-industrial wastes. The study was carried out in the districts of Rangpur, Rajshahi, Pabna, Kustia, Jessore, Khulna and Gazipur. Crop residues were collected from rice, wheat, maize, ground nut, soybean, sugarcane and coconut field. BRRI dhan29, BARI Gom-26, BARI Hybrid Maize-9, BARI Badam-8, Shohag and Ishurdi-16 were the sampling variety of rice, wheat, maize, ground nut, soybean and sugarcane, respectively. The coconut variety was local. Representative quantities of crop samples were collected. Agro-industrial wastes were collected from rice mill, wheat and maize flour mill, sugar mill, rice bran oil and coconut oil mill. Collected samples are processed for analysis. One important index of crop residue i.e. Residue Production Ratio (RPR) was measured by the quantity of crop straw/stover to produce each kilogram of grain. Residue production ratios for agro-industrial process wastes were determined by the quantity of waste to produce each kilogram of edible part of crop.

Achievement/Findings:

More than 200 crops are cultivated in Bangladesh. Every crop has many varieties. Characterization of crop depends on variety to variety and season to season. Generation of crop residue depend on area coverage and yield of the crop. Versatile usage of crop resdue was observed. This year survey work was confied with only seven crops with taking variety each. The study need to be carried out next year with new crop and new variety
