Rice threshing is one of the important factors affecting grain losses, quality and quantity. The wearing of the secondary threshing drum forks and bearing occurs crop blockage inside the threshing housing that lowers the combine harvester field capacity and increases the total grain losses. To overcome this problem, this study aimed to modify the c...

This study was carried out at the Dept. of Agric. Eng. Faculty of Agric.Mansoura University to determine the required shear force for cutting some fruit tree branches as a relevant to the performance of pruning and chopping machinery. The shear tests were conducted using some fruit tree branches after pruning directly, after 10 days drying and afte...

The auxiliary roll of the rice combine harvester were developed and manufactured from local material to reduce wearing rate for threshing device also minimize fuel consumption and energy requirements. Replacing auxiliary roll knives arranged in a spiral instead by forks separating on length were 90 cm with seven rows and each row has four blades to...

T his study was carried out during 2014 summer season to identify the requirements of cucumber precision planting. Some cucumber seed properties were determined to design the proper seed disc for cucumber seed planting. The field experiment was carried out at El-Damaiera Village, El-Dakhlia Governorate. A pneumatic planter was used to plant cucumbe...

A study was carried out at Kalabsho Region, El-Dakhlia Governorate, during 2012 summer season to identify the effect of organic fertilization on rice mechanical drilling, soil charactersties and total yield. Sugar beet tops were used as an organic fertilizer. They were broadcasted upon the soil surface and tilled using a rotary plough. The experime...

This study was carried out at Agric. Eng. Dept., Agric. Fac., Mansoura Univ. during 2009 season. The aim of the present work is evaluate a complete system to produce rabbits pellet using plant residues which incorporates safety and simply operated. The complete system consists of grinding machine and combined mixer and forming pellet machine. The g...

This study was carried out at El-Gemmeiza Ag. Res. Station, El-Gharbia Governorate, during 2006 summer season. Potato seed tubers Sponta variety were planted using a modified potato planter-ridger at row spacing of 0.75 m, one tuber/0.25 m within row and 0.10 m planting depth. The modified machine was tested at forward speed levels of 3.35, 3.95, 4...

This study was carried out at EL-Dakhlia Agricultural Experiments Direction, Agricultural Researches Center, in Mansoura city, Dakhlia Governorate, during 2003 season. In this study, garlic physical and mechanical properties were determined as relevant factors to design and operating the used machines for garlic production. At the duration of this...

This study was carried out during 2002 and 2003 summer seasons at El-Gemmeza agricultural station, El-Garbia Governorate, to study the effect of some strip-till methods on maize grain yield comparing with the conventional tillage method. The mean values of the obtained results could be summarized in the case of operating the tested machines at forw...

Recently, special attention has been given to kiwifruits production in Egypt due to its great nutritive and economic values. This research aims to study the effect of packages on cooling capacity and quality of kiwifruits during different cold storage periods of 15, 30, 45, 60, 75, 90, 105, 120, 135, 150, 165 and 180 days followed by three differen...

This search was carried out at El-Gemmeza agricultural station, El-Garbia Governorate to study the effect of rice planting methods on flowering time and grain yield. The used planting methods were mechanical drilling, mechanical transplanting, and manual transplanting. The highest land preparation and planting field capacity of 0.36 fed/h was obtai...

This research was carried out at El Mansoura Laboratory of soil fertility in Mansoura sity, Dakahlia Governorate, during 2001 season to mill two garlic cultivers (Balady and Sides-40) after slicing the cloves and drying the slices. The aim of garlic milling is producing garlic powder which is considered as the most effective commercial preparation...

Rice crop is considered as an important cereal crop in Egypt. The total cultivated area was 1.25 million feddans approximately, which produced about 2.50 million tons straw (Ministry of agricultural, 2001). In despite of the economic importance of rice crop, it causes a serious environmental problem, which is straw burning after harvesting. So, the...
