| This experiment was conducted in lathhouse , Dep . of Horticulture , College of Agriculture , University of Baghdad ,Abu Ghraib during growing seasons 2011 and 2012. Pear seedling Pyrus communis L. cv. Cocia two year old were used , This study included two factors ;spraying with liquorice extract (L) and addition of sulphur (S) wich done in the March . The first factor three levels were used, 0 (L0) , 5 (L1) , 10 (L2) gm / L and three levels of sulphur, 0 (S0) , 50 (S1) , 100 (S2) gm / seedling . Each treatment replicated three times with a factorial experiment using RCBD. The number of trees used were 27 trees. The experimental results showed that liquorice extract 10 ml /L (L2) and sulphur at 100 gm (S2) that mean interaction (L2S2) significantly gave the highest plant height of 64.55 and 83,42 cm and the highest stem diameter of 0,26 and 0,41 cm and the highest leaf dry percentage of 40,14 and 42,41% and the highest leaf content of chlorophyll of 41,93 43,98 SPAD unit and the highest leaf content of sulphur of 0,23 and 0,24% and the highest leaf content of nitrogen of 1,24 and1,31% for two season respectively , while the lowest value of these parameters were found in the control (L0S0) treatment . | ||
