Abstract
Agriculture mostly depends on suitable supply of water for irrigation. Before application of water, water quality must be measured because of secure in-toxic food production If the Poor quality of irrigation water is not managed properly then it poses many hazards to plant production. So for the better plant and crop production the quality of the water need to be analyzed properly and improving further management. With the finality to analyze the irrigation water quality (physico-chemical parameters), different places of Pabna District were evaluated. Twenty water samples were collected in the winter season (January-march) and then they were examined for temperature, pH, electrical conductivity (EC), total dissolved solids (TDS), sodium adsorption ratio (SAR), soluble sodium percentage (SSP), residual sodium carbonate (RSC), and so on. The study indicates that waters were found within the permissible limits for irrigation purposes. So, The irrigation water samples from surface water, Ground water and deep tube-wells water can be used in agricultural purposes.
Highlights
Bangladesh is an agricultural based economy but it’s not totally depends on rainwater
Because the physico-chemical properties has a strong impact of Irrigation water quality and on the productivity of plants and crops, health soils, and the surrounding ecosystems, was important find out the quality of the irrigation water of Pabna District
Different physico-chemical properties of irrigation water of Pabna District were matched with the water quality standards set for irrigation
Summary
Bangladesh is an agricultural based economy but it’s not totally depends on rainwater. Irrigation helps grow agricultural crops and this crops are dependent on water quality. It has a great importance of this analysis of different parameters of the water of the Pabna district. Water quality refers to the characteristics that will influence its suitability. These are physical, chemical and biological characteristics. The analysis of the parameters of the water sample is important. Depending on this we will get a good quality of water that will be usable for the growing crops or other respectable uses. Water can be polluted by using different fertilizer and pesticides like diazinon into land for better food production [22]
