EFFECT OF PLANTING SPACES AND POLLARDING NUMBER ON ROOTING GROWTH DEVELOPMENT IN LEUCAENA STAND
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...

| Summary: | 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 % ). |
