this study examined suitable mechanized methods to seed rice in dry-bed conditions using dried seeds and determined the most suitable varieties for each method. the experimental design was strip-plots in a randomized complete block design with two factors (seeding methods and rice varieties) and three replications. the testing took place during 2003-2004 at the shavour agricultural research sta...

otal hydraulic resistance on an upland agricultural site may be influenced by several factors including standing vegetation. In this laboratory study, Darcy-Weisbach roughness coeflcients were measured for corn, cotton, sorghum, soybeans, sunflower, and wheat vegetation. Experimental variables used in this investigation in addition to crop type included plant population, row spacing, row orient...

Rows seats distance is a key parameter for the comfort on coaches. This distance it is also important for the passenger safety and also for example to extend the use of rearward facing CRS in a safer way. This study analyses what could be the minimum distance (based on comfort from volunteer) and how this comfort distance is affecting the passengers level of protection in R80 frontal impact wit...

The present study investigated the impact of planting spacing on tomato crop growth, water productivity, and fruit quality under different regimes. Thus, a field experiment was conducted using randomized complete block design in factorial arrangement treatments. plants were grown at three patterns: 30 cm row-to-row spacing, 60 90 which marked as (G1), (G2), (G3), respectively. For each pattern,...

Considerable effort is expended to conserve energy and water in current greenhouse systems, and look for alternative energy sources, especially passive heating and cooling strategies. Proper environmental management systems can significantly change the energy and moisture dynamics of greenhouse production systems. In this study, specifically, influences of dynamic row spacing on energy and wate...

Quenching cooling rate of rotary hollow cylinder by one row of water impinging jets has been experimentally studied. Water jets (d = 8 mm) with sub-cooling 55 to 85 ◦C and Reynolds number 8,006 to 36,738 impinged over rotary hot hollow cylinder (rotation speed 10 to 70 rpm) with initial temperature 250 to 600 ◦C. Impingement impact angle of row of jets varied between 0 to 135 ◦ and jet-to-jet s...

The present paper reports measurements carried out in a centrifugal compressor equipped with double row of low solidity partial vane diffuser. Performance of the compressor is measured with three sets of double row diffusers with different radial spacing between the diffusers. From these measurements best configurations are identified and static pressures on the diffuser walls and probe measure...

Mung bean is among the most important pulses crop cultivated from low to midland agro-ecological zones of world including Ethiopia. The study was conducted at Abine Germama Kebele in 2020/21 cropping season ( rainy ) on Adamitulu Jido Kombolcha Wereda. We used mung variety so called Arkebe for this experiment. trial also determine optimum row spacing and phosphorus fertilizer rate better grain ...
