Soil Propertes, Nutrints availability and Wheat Productivity as affected By Compost and Nitrogen Sources
Soil, Water and Environment Research Institute (SWERI), Agricultural Research Center (ARC), Giza, Egypt.
Abstract
Two field experiments were performed in Agricultural Farm of Sides Agricultural Research Station , ARC ,Beni-Suef Governorate , Egypt to investigate the effect of different levels of compost (0.0 , 4.8 and 9.5 Mg ha-1 ) and different nitrogen sources , i.e. , without ,ammonium ,sulphate (AS) , ammonium nitate (AN) and urea(U) on some soil chemical and physical properties after wheat harvested as well as wheat growth parameters ; yield and its components. The results show that all studied soil properties and nutrient availability were improved due to increasing compost level, except soil salinity, which increased by increasing compost. Also, increased compost level increased wheat growth, yields and its components as well as N, P and K content in grains and straw. N-fertilization did not affect soil properties and nutrient availability except soil reaction and soil available phosphorus. It could be arranged nitrogen sources on reducing soil pH and increasing soil available phosphorus in the descending order as follow : AS > AN > U . Irrespective of nitrogen sources, nitrogen application was significantly increased all studied growth parameters, yield and yield components and nutrients content, where as fertilizer surpassed other nitrogen forms followed by AN and U. The treatment of 9.5 Mg ha-1 compost +179 g Nha-1 consider the best treatment of wheat productivity and improved soil properties and fertility under the condition of alluvial soil for middle Egypt.
