Última Maximizing wheat crop yield using a mobile thresher at small holdings CIGR Journal F. A., Shreen; Badr, S.E.; Morad, M.M.. This study was carried out at a private farm in Owlad Sakr District, Sharkia governorate Egypt during 2015 summer season. It aimed to maximize wheat crop yield by modifying a stationary thresher. The modification involved tractor mounting the thresher to move among the field and the thresher was attached with a feeding device and a straw container. The experiment was established and designed statistically as a factorial experiment in complete randomized blocks with three replications. The tested treatments were wheat plant feeding rate levels of 500, 700,900 and 1100 kg/h and wheat plant moisture content levels of 16%, 18% and 20% (w.b.). The obtained results showed that the modified thresher decreased the total grain losses with 45.24%, increased the...

I.; Olukunle, O. J.; Oluwalana, I. B.. An active evaporative cooler for short-term storage of fruits and vegetable has been developed to improve the shelf life of fruits and vegetables for small holder farmers in Southern Nigeria.  The evaporative cooler uses palm fruit fiber as cooling pad material which is considered a waste in palm oil production in Nigeria and consists of three suction fan, automatic water control switch, water pump and evaporative cooling chambers.  The performance of cooler was evaluated in terms of temperature drop, efficiency of the evaporative cooling and cooling capacity.  The temperature drop ranged from 40C to 130C while the relative humidity of the ambient air was increased to 96.8%.  The cooler could drop the temperature close to wet bulb depression of ambient air...
