This study investigates the incidence of Escherichia coli in cauliflower, bitter gourd and soil profile drip-irrigated with municipal wastewater in a semi-arid peri-urban area in India. There were four treatments: drip irrigation with primarily treated municipal wastewater through inline (non-pressure compensating) surface drip (T1), inline subsurface drip (T2), bioline (pressure compensating) subsurface drip (T3) and bioline surface drip (T4). Results revealed that T1 had the highest concentration of E.coli (35 ± 2.66 and 25 ± 2.26 colony forming unit (CFU) g˗1) and T3 had the lowest concentration of E. coli (29 ± 2.29 and 18.9 ± 2.04 CFU g˗1) for cauliflower and bitter gourd, respectively. In bitter gourd top fruits (1 m above the ground level), the E. coli count was significantly lower (p < 0.05) than in the surface level fruits. There was also a considerable reduction of E. coli counts in bioline drip lateral as compared to the inline drip. A higher concentration of E. coli (470 ± 70.5 and 410 ± 36.9 CFU g˗1 soil) was also found in the top soil (0–0.15 m) in T1 treatment, while the minimum (154 ± 13.86 and 95 ± 14.25 CFU g˗1) was observed in T3. Hence, bioline drip lateral may be a better option for wastewater irrigation as compared to inline drip to reduce microbial contamination of crop and soil.

Hater resource managers in semi-arid regions are faced with some unique problems. The wide variations in precipitation and stream flows in semi-arid regions increase man's dependence on the ground water resource for an ample and reliable supply of water. Proper management of the ground water resource is absolutely essential to the economic well being of semi-arid regions. Historians have discovered the remains of vanished advanced civilizations based on irrigated agriculture which were ignorant of the importance of proper ground water resource management. In the United States a great deal of effort is presently being expended in the study and control of toxic discharges to the ground water resource. What many public policy makers fail to understand is that the potential loss to society resulting from the mineralization of the ground water resource is potentially much greater than the loss caused by toxic wastes discharges, particularly in developing countries. Appropriations for ground water resource management studies in developed countries such as the United States are presently much less than those for toxic wastes management and should be increased. It is the reponsibility of the water resource professional to emphasize to public policy makers the importance of ground water resource management. Applications of ground water resource management models in the semi-arid Central Valley of California are presented. The results demonstrate the need for proper ground water resource management practices in semi-arid regions and the use of ground water management models as a valuable tool for the water resource manager.

Abstract Agricultural water resources have been limited over the years due to global warming and irregular rainfall in the arid and semi-arid regions. To mitigate the water stress in agriculture, mulching has a crucial impact as a water-saving technique in rain-fed crop cultivation. It is important mainly for preserving soil moisture, relegating soil temperature, and limiting soil evaporation, which affects the crop yield. Mulching has many strategic effects on soil ecosystem, crop growth, and climate. Mulch insulates the soil, helping to provide a buffer from cold and hot temperatures that have a crucial activity in creating beautiful and protected landscapes. This study has accumulated a series of information about both organic and plastic mulch materials and its applicability on crop cultivation. Moreover, future research potentials of mulching with modeling were discussed to quantify water loss in agriculture.
