Long-term experiments are leading indicators of sustainability and serve as an early warning system to detect problems that threaten the future productivity. Soil quality assessment is considered as a tool for evaluating the sustainability of soil management practices. In a long-term crop rotation e

Visual interpretation of Landsat-7 ETM-7 bands 4, 3 and 2 was depending on many elements such as tone, shape, size, pattern, texture, shadow, and association. The interpretation was done to extract all important landscape. A physiographic analysis using visual interpretation was carried out to delin

Two Field experiments on potato (Solanum tuberosum, L.) crop were carried out at El-Qanater Horticultural Research station, Kalubiya, Governorate, Egypt for two successive seasons 2009 and 2010.

A field experiment was carried out at Bahtim Agricultural Research Station Farm during 2010/2011 and 2011/2012 seasons. The experimental site is located at lat. 30.80, long 31.16 and 14.00 m above the mean sea level, to study the effect of farmyard manure (FYM) application rates (zero, 12 and 24 t/h

Broad bean plants response to the effect of organic and inorganic nitrogen fertilizer usually differs and interacts with different available soil water deficit. Two field experiments were conducted during both growing seasons 2009/2010 and 2010/2011 using faba bean plant (variety Giza 643), at the E

A field experiment was carried out at El- Gemmeiza Agricultural Research Station, El-Gharbia Governorate during the two summer growing seasons, 2011 and 2012 located at lat. 30.47, long 31.00 and 14.80 m above the mean sea level to study the effect of nitrogen fertilizer rates, i.e., control (withou
