Variants with different irrigated doses with fertigation were evaluated at pear orchard variety Lucas/MA from 2004 to 2010. This experiment took place in planting established in 1999 in farmers cooperation Dolany. Four experimental variants were evaluated: 1)non - irrigated control, 2) drip irrigation of 1,6 l/h output, 3)drip irrigation of 2,3 l/h output. 4)drip irrigation of 3,5 l/h output. Each variant had twenty trees at four repetition, then together eighty trees for evaluation. Irrigation was automatic. A special fertilizer (Kristalon violet) was supplied by the irrigation once a week in concentration 3 g/tree/1 dose. There were ten application of Kristalon during vegetation. The crops (kg/tree), weight of 100 fruits. mass defect and rotting of fruit during storage were monitored at each variant. The highest crops (30,8 kg/tree) were recorded at variant with drip irrigation of 3,5 l/h output, with maximum supply of water with fertilizer Kristalon.
