Vegetative growth, fruit set, yield and fruit quality of "Le-Conte" pear grown under calcareous soil conditions as affected by different levels of nitrogen, phosphorus and potassium
"Le-Conte" pear fruiting trees grown in newly reclaimed soils were fertilized with different levels of nitrogen, phosphorus and potassium fertilization during three successive seasons of 2006, 2009 and 2010. However, results were calculated for the two seasons of 2009 and 2010. Tree veget...
