| dc.description | Water is the most important in shaping the land and regulating the climate and most
important compounds that profoundly influence life (Gorde and Jadhav, 2013). Water
also is one of the main important abiotic components of the environment.
Approximately, 97% of the total water is found in oceans, which is not appropriate for
drinking and irrigation, and only 3% is considered as fresh water, out of which 2.97% is
found as glaciers and ice caps. Only the remaining little portion, 0.03%, is obtainable as
surface and ground water for human use (Muhammad et al., 2013).
There are several factors such as ions, salts, heavy metals, toxic elements, fertilizers,
pesticides, insecticides, and industrial wastages etc. that affect water quality and make
the water quality poor. Using this poor quality water, it might deteriorate soil properties,
crops yield and quality (Sarker et al., 2000). Irrigated agriculture is dependent on
adequate water supply of usable quality. Water quality concerns have often been
neglected because good quality water supplies have been plentiful and readily available
(Islam et al., 1999). This situation is now changing in many areas. Intensive use of nearly
all good quality supplies means that new irrigation projects, and old projects seeking new
or supplemental supplies, must rely on lower quality and less desirable sources (Cuena,
1989). Irrigation water quality is related to its effects on soils and crops and its
management. High quality crops can be produced only by using high-quality irrigation
water keeping other inputs optimal. Characteristics of irrigation water that define its
quality vary with the source of the water. There are regional differences in water
characteristics, based mainly on geology and climate. | en_US |
| dc.description.abstract | A laboratory experiment was performed to determine the chemical constituents of
groundwater for crop production in Dinajpur Sadar Upazila under Dinajpur
district of Bangladesh. Thirty samples of groundwater were gathered from
different areas of Sadar Upazila for the evaluation of chemical constituents. The
research work was accomplished to measure the degree of water quality and to
forecast the suitability and acceptability for irrigation usage. Groundwater
samples collected from selected areas were classified by examining chemical
constituents present therein. Several parameters like Ca, Mg, HCO3, B, Fe, Mn,
pH, EC, TDS, SAR, SSP, HT, permeability index and Kelly’s ratio were
considered for the classification. In the study areas, the water contained an
appreciable amount of Ca, Mg, Na and K. The concentrations of Fe, Mn, Zn, Cu,
B and SO4 were found within safe limit for irrigating crops. The pH value of all
the water samples fluctuated from 6.16 to 7.51 indicating slightly acidic to slightly
alkaline and found `suitable' for irrigation and public health. EC and TDS values
of water samples were found suitable. On the basis of EC and SAR, all the waters
were found low salinity and low to medium alkali hazards. As per SSP values of
water samples, all samples were good class for crop production. On the basis of
HT, 3 samples were moderately hard, 16 samples were hard and the rest 11
samples were very hard categories. According to TDS, 7 samples were moderate
quality while rest 23 samples were slightly hard which were not harmful for crop
production and public health. The water might not be problematic for the dual
usage. All the waters under test were suitable and might be recommended for both
irrigation and drinking purposes in the study area. It is suggested that water should
be analyzed systematically for understanding the impact of dissolved ions on the
quality crops and soil health management as well as public health in the study
area. | en_US |
