Testing of agricultural sprinklers is necessary to find the optimum field operating conditions with minimum cost while satisfying design water distribution criteria. In the present study two twin-nozzle agricultural sprinklers were tested in field under ten different operating pressures ranging from 1.6 kg/cm² to 3.5 kg/cm². In each experiment sprinkler discharge rate, nozzle pressure, radius of throw, and water distribution pattern around the sprinkler were observed. The average discharge coefficients of the two sprinkler nozzles were determined.

An inspection of a tidal river concrete bridge in the Mekong River Delta discovered a large number of map cracks in most piers within the tidal range. These map cracks distribute nearly vertically and horizontally with a distance of about 15 and 20 cm. Many of them have a width over 1 mm and a depth exceeding the thickness of the reinforcement protection concrete layer. Considering the location and the pattern of cracks, the most acceptable hypothesis on their cause was the strain gradient in concrete induced by the change of moisture content during tide rise and fall, i.e.

A field experiment was conducted to study the horizontal and vertical movement of moisture front under point and line source of trickle irrigation system by operating system up to three hours. Emitter of 2, 4, 8 lph discharge were used for studying the moisture movement under point source and 4, 5, 8 and 10 l/m/hr discharging emitter for the wetting pattern under line source. The effect of antecedent moisture content on Radial as well as Vertical movement was also considered in this field Experiment.

An attempt was made to study the soil water movement under two type of plastic mulch (black and white) with drip irrigated eggplant on a line source dripper. Both spatial and temporal variation of wetting pattern was determined in sandy loam soil using surfer 15 software. The layout of the experiment was three treatments tested, black mulched drip irrigation (BM+DI), white mulched drip irrigation (WM+DI) and drip irrigation without mulching. The results of the study indicated that DI + BM and DI + WM treatments distinctly decreased water applied in the order of DI + WM < DI + BM < DI.

Water is a critical input for productivity enhancement especially of field crops. Its judicious and optimum use is needed utmost for realizing higher resource use efficiency and plugging gaps in production. Key technological interventions, which could alter or rectify the usage pattern or strategies in freshwater utilization in agriculture, are the need of the hour. Precision water management approach could help in conserving and making more-efficient use of scarce water resources through integrated management combined with selected external inputs/technologies.

In this study, MgO loaded TiO2 Degussa P25 powders were prepared by wet impregnation with difference in the amount of Mg content (i.e 0.5-10%). X-ray patterns studies have not proven the new phases in the MgO loaded TiO2 catalysts as well as BET and SEM studies have not shown the change of its particle size and specific surface area in compared with initial TiO2.
