Applying of arbuscular mycorrhizal fungi (AMF)‎ and rock phosphate to wheat (Triticum aestivum L.)‎ grown on calcareous soil and irrigated at different irrigation intervals and effect of plant growth and soil physical properties

الملخص EN

A field experiment was conducted along two the successive seasons of winter (2014/2015) and (2015/2016) at El-Nubaria Agricultural Experimental Station of the Agricultural Research Center (ARC), west of Alexandria, Egypt.

Aim was to evaluate the effect of arbuscular mycorrhiza fungi (AMF) and rock phosphate (RP) application as well as the effect of irrigation intervals on soil properties and growth of wheat (Triticum aestivum L.) grown on sandy clay loam calcareous soil.

The experiment was factorial (3 factors) with 12 treatments and three replicates.

Three irrigation intervals 15, 21and 35 days, two RP treatments non and 16 kg P ha-1 and two AMF (non and AMF) treatments.

AMF under moderate 21 day irrigation interval combined with RP was mostly effective in increasing total porosityand saturated hydraulic conductivity as well as decreasing bulk density.

AMF + RP and irrigation every 21 days gave highest values of most growth and yield characters along with NPK content
