In: Annals of Agricultural Science, Moshtohor 2018.v.56(2)Summary: A field experiment was conducted during the two successive seasons of 2015/2016 and 2016/2017 at Central Laboratory for Agricultural Climate (CLAC), Agricultural Research Centre, Dokki, Giza govemorate, Egypt to study the effect of two green bean cultivars (Paulista and Samantha) and three rates of rock phosphate (fine and granules) as a natural resource of P mixed with sand substrate in comparison with calcium superphosphate with recommended level on growth and yield of green bean (Phaseolus vulgaris L.) under plastic house conditions. Regarding the green bean cultivars, Paulista gave higher plant height, number of leaves, canopy and root fresh and dry weight than Samantha cultivar. Paulista,cultivar produced the highest values of total pod yield per plant during the two successive seasons. Increasing phosphorus level (fine or granule rock phosphate) up to 150% enhanced pod yield with both used cultivars. The highest vegetative growth and yield were obtained from 150% fine rock phosphate combined with Paulista cultivar. Tissue nutrient analysis show that increase phosphorus level by rock phosphate source led to increase nutrient percentage for NPK in green beans leaves in comparison with recommended phosphorus dose applied as calcium superphosphate. The economic consideration among phosphorus and different P sources revealed that fine rock phosphate with Paulista cultivar gave the highest net income per greenhouse

A field experiment was conducted during the two successive seasons of 2015/2016 and 2016/2017 at Central
Laboratory for Agricultural Climate (CLAC), Agricultural Research Centre, Dokki, Giza govemorate, Egypt to
study the effect of two green bean cultivars (Paulista and Samantha) and three rates of rock phosphate (fine and
granules) as a natural resource of P mixed with sand substrate in comparison with calcium superphosphate with
recommended level on growth and yield of green bean (Phaseolus vulgaris L.) under plastic house conditions.
Regarding the green bean cultivars, Paulista gave higher plant height, number of leaves, canopy and root fresh
and dry weight than Samantha cultivar. Paulista,cultivar produced the highest values of total pod yield per plant
during the two successive seasons. Increasing phosphorus level (fine or granule rock phosphate) up to 150%
enhanced pod yield with both used cultivars. The highest vegetative growth and yield were obtained from 150%
fine rock phosphate combined with Paulista cultivar. Tissue nutrient analysis show that increase phosphorus level
by rock phosphate source led to increase nutrient percentage for NPK in green beans leaves in comparison with
recommended phosphorus dose applied as calcium superphosphate. The economic consideration among
phosphorus and different P sources revealed that fine rock phosphate with Paulista cultivar gave the highest net
income per greenhouse
