Impact of Improved Soil Properties on Establishment of Moringa peregrina seedlings and a trial to decrease its Mortality Rate.

Moringa trees are subjected to extreme drought in its hyper arid environment especially in South Sinai. Unmanaged utilization of this valuable tree is very short-sighted and leads to high mortality, low recruitment, and poor survival of its seedlings. The present study aims to find the conditions for optimum growth during its establishment period. The seedlings were treated by two soil conditioners; organic matter and nutrient solution, besides gibberellic acid. Two hundred seedlings of M. peregrina with the same age were transplanted into the field. From those seedlings, 120 seedlings were selected and divided into six categories for five treatments and control. Each category was randomly distributed over the three plots. Parameters measured for growth seedlings include shoot height, crown cover, number of branches, number of leaflets, and vitality. Results showed that the seedlings reacted differently to each of the five treatments. A mixture of gibberellic and nutrient solution produces highly significant differences in vegetative parameters compared with control. Therefore this treatment is recommended to enhance growth with lowest mortality rates.
