| Abstract | ||
| This study was conducted at mosul university in Leucaena stand which planted at (2005) with six plant spaces (1*1)m.,(0.5*1)m., (0.5 *0.75)m. , (0.5*0.5)m. , (0.25*0.75)m. , (0.25*0.5)m., four cutting period (one month , two month , three month,six month ), and two cutting height (25,50)cm. through master study of Al- qassar (2007) who took the result of first year and Akreyi (2008) who took the result of second year after planting , to study the effect of this factors on refoliation , biomass production and its quality . At November (2006) the trees were taken off to know the effect of studied factors on the growth of roots . The characters (fresh and dry weight , secondary root number,main root length, nitrogen percent , total absorption of nitrogen , phosphorus percent , potassium percent, callesium percent and dry matter percent ) were studied . The results showed that the plant space (0.5*1)m. at three month cutting period and cutting height (50) cm. was differed significantly with other treatments in (fresh and dry weight of roots , total absorption of nitrogen , calisium percent )which were (624.00 gm.,324.66 gm., 1.21 gm./plant and 0.374 % ). | ||
