The objective of this study was to determine the effect of paddy rice ploughing techniques on water use and the yield of rice crop, as well as water use efficiency for rice growing in small-holder irrigation schemes. The study was conducted at a farmer’s field in Powo B sub-block of Maugo Irrigation Scheme. The period of study was from July 2019 to January 2020, which is the rice season. The experimental site was located in the vicinity of Olare Shopping Centre, Kamenya Sub-location, Kochia East Location, Kochia Ward, Rangwe Sub-County, Homa Bay County, Nyanza Region, Kenya in Maugo rice scheme in Kenya. In the study, four irrigation tillage practices were applied: ox-plough, conventional ox-plough, hand hoe and tractor ploughing. The results showed that conventional ox-ploughing consumed the highest amount of water at 1240 mm. The highest water use efficiency of 0.49 kg/m3 and highest yield of 5.7 tons/ha were observed for hand hoe ploughing. Use of the hand hoe ploughing technique increased yields by 20 percent, as compared to the conventional ox-ploughing. Therefore, the use of water for ploughing is not necessary in the study area. Future research will be needed to see how farmers are adopting the technology before scaling up to full mechanization, as partial mechanization was not profitable.

<p>Better management practices have been used to increase soil water storage and reduce evaporation from the soil surface to optimize crop water use efficiency (WUE) in irrigated agriculture. A field study was conducted to evaluate the effect of  conventional tillage (CT), No-till (NT) and strip tillage (ST) practices on yield, water use (WU) and WUE of sugarbeet (Beta vulgaris L.) on a clay loam soil under over-head sprinkler irrigation system in the northern Great Plains. Tillage treatments were replicated five times in a randomized block design. Seasonal WU and WUE for sugarbeet root and sucrose yield were determined for the 2018 and 2019 growing seasons according to the water balance and WUE equations under three tillage practices. Results showed that no significant differences due to tillage treatment were found for crop WU, root yield, sucrose yield, and WUE for sugarbeet root and sucrose in 2018 and 2019 growing seasons. In 2019, the average value of WU across three tillage systems (616 mm) was significantly greater relative to 2018 (468 mm) due to atypical large rainfalls (218mm) occurred in September of 2019. Consequently, WUE values for both root and sucrose yield in 2019 under CT, NT, and ST were significantly greater than those in 2018. While NT and ST practices are promising alternative to CT for agricultural production in this region, further research is needed prior to making any recommendation.</p>

The purpose of the report is to analyze the possibilities for using heating energy for the building of the Faculty of Technics and Technology of Yambol at Trakia University of Stara Zagora, Bulgaria, provided by renewable sources. The selection of the water-water heat pump system is made after determining the heat demand for the building when applying the energy saving measures proposed in the energy efficiency audit. The possibilities for using groundwater for water supply were studied to heat the building.

AbstractThe focus of marine autonomous vehicles has largely been for offshore applications. The use of such observational platforms in estuaries and coastal embayments has been limited by the designs of the widely used AUVs, which are mostly for open ocean studies. Here we discuss the development and testing of an automated unmanned boat for shallow water use for (1) current velocities using an acoustic Doppler current profiler, (2) bathymetry using an echo sounder, (3) seabed configuration using a side-scan sonar, or (4) shallow, sub-bottom stratigraphy using a chirp sonar. After 91 h and 453 km of total distance surveyed, results demonstrate the numerous advantages this automated boat (Auto-boat) possesses over manned survey vessels. For example, the Auto-boat had the advantage in the accuracy of repeating a planned route continuously over at least a tidal cycle to resolve tidal and subtidal current velocity profiles. It provides endurance, energy efficiency, ease of operation, and capability of coverage of shallow areas close to shore.
