Determination of Ground Water Quality for Agriculture and Drinking Purpose in Sindh, Pakistan

The study was conducted to assess the quality of ground water from different Talukas of district Tando Muhammad Khan for drinking and agriculture purpose. Water samples for determining the water quality were collected in one liter polyethylene bags by observing standard sample collection method. It was ensured that sample collection sites must be at least 500 feet away from each other. Physical and chemical parameters of ground and surface water samples such as pH, Electrical Conductivity (EC), Turbidity, Colour, Taste, Odour, Alkalinity as CaCO 3 , Bicarbonate (HCO 3 ), Carbonate (CO 3 ), Calcium (Ca), Magnesium (Mg), Hardness, Sodium (Na), Potassium (K), Chloride (Cl), Phosphate (PO 4 ), Total Dissolved Solids (TDS) and Arsenic (As) were determined. The study clarified that pH and odour was within the permissible limits in majority of samples whereas, Arsenic (As), Hardness, Sodium (Na), Total Dissolved Solids (TDS), Taste, Chloride (Cl) and turbidity were beyond the permissible limits set by WHO. The groundwater status in Tando Muhammad Khan district, TDS in 50% samples, Chloride in 54.16% samples, Sulphate in 44.8% samples, Calcium in 38.5% samples, Sodium in 54.16% samples, hardness in 21.88% samples were beyond the WHO’s permissible limits for human consumption.

Estimation Spatial Distribution of Sodium Adsorption Ratio (SAR) and Residual Sodium Carbonate (RSC) in Groundwater of Tando Muhammad Khan Pakistan

This study was conducted to evaluate factors regulating groundwater quality in an area with agriculture as main use. Water samples for determining the water quality were collected in one liter polyethylene bags by observing standard sample collection method. It was ensured that sample collection sites must be at least 500 feet away from each other. Sodium Adsorption Ratio (SAR) and Residual Sodium Carbonate (RSC) were determined from the collected water and it was observed that in Tando Muhammad Khan taluka, the Sodium Adsorption Ratio (SAR) in the samples ranged from 11.06 to 53.29, the highest (53.29) SAR was in UC Tando Saindad, while lowest (11.06) in the sample collected from UC-2 of Tando Muhammad Khan. The Residual Sodium Carbonate (RSC) in 36 collected groundwater samples ranged from 0.61 to 5.15 meq/l, the highest (5.15 meq/l) was in UC Tando Saindad, while lowest (0.61) in the sample collected from UC-3 of Tando Muhammad Khan. It was concluded that the SAR levels of groundwater samples indicated an alarming situation and most of the ground-water samples had SAR (<7.5 meq/l) and RSC (<2.0 meq/l) above permissible limits of WHO for agriculture use therefore, it is not suitable for agriculture as well as drinking.

Studies on the Nutritional Characteristics of some Commercial Wheat Varieties of Dry Land and Wet Land Grown in Sindh Province

The present research was carried out to investigate the nutritional characteristics of some commercial wheat varieties of dry land and wet land grown in Sindh province during 2011-12 at Institute of Food Sciences and Technology, Faculty of Crop Production, Sindh Agriculture University Tandojam. Four irrigated land (Inqulab, TD-1, Sarsabz and kherman) wheat varieties and four dry land (TK-3, Marvi, PK-85, Sassi) wheat varieties were collected from their respective areas and subjected to chemical analysis. The bio-chemical characteristics of dry land and wet land wheat varieties differed significantly. Chemical analysis indicate that moisture (13.06%), protein (14.83%), dry gluten (9.03%), wet gluten (35.66%), gluten index (73.8%), starch (75.83%) and zeleny (68.66%) contents were recorded higher in wet land wheat varieties than those of dry land wheat varieties with moisture (12.66%), protein (11.9%), dry gluten (8.2%), wet gluten (32.93%), gluten index (64.53%), starch (68.66%) and zeleny (58.33%). This study reveals that availability of water and environmental factors are directly related with the nutritional characteristics of wheat varieties. This study clarify that wet land wheat varieties are better in the context of nutritional qualities.
