Dissertation note: Thesis (PH.D.) - Cairo University - Faculty Of Agriculture - Department Of Soil Science Summary: Phosphorus deficiency is one of the principal yield limiting factors for crop production in soils of EgyptThe objectives of this study were to evaluate P - use efficiency in 17 corn cultivars under P - deficient soil and to elucidate some of the putative mechanisms governing P - use efficiencyTo achieve this goal , three pot experiments were carried out ; in the first experiment the corn cultivars were grown in P - deficient soil at three levels of P (0 , 50 and 75 mg P kg - 1 soil) for 30 days after plantingThe results showed that shoots and roots dry matter production and P content were significantly affected by P treatments and corn cultivarsBased on dry matter production (shoots plus roots) at low P level and P - use efficiency , corn cultivars were classified as efficient and responsive (ER) , efficient and non responsive (ENR) , non efficient and responsive (NER) , and non efficient and non responsive (NENR)

Phosphorus deficiency is one of the principal yield limiting factors for crop production in soils of EgyptThe objectives of this study were to evaluate P - use efficiency in 17 corn cultivars under P - deficient soil and to elucidate some of the putative mechanisms governing P - use efficiencyTo achieve this goal , three pot experiments were carried out ; in the first experiment the corn cultivars were grown in P - deficient soil at three levels of P (0 , 50 and 75 mg P kg - 1 soil) for 30 days after plantingThe results showed that shoots and roots dry matter production and P content were significantly affected by P treatments and corn cultivarsBased on dry matter production (shoots plus roots) at low P level and P - use efficiency , corn cultivars were classified as efficient and responsive (ER) , efficient and non responsive (ENR) , non efficient and responsive (NER) , and non efficient and non responsive (NENR)
