Effect of rice strow incorporation and inoculation with cyathus stercoreus on growth, biomass, drought resitance and nodulation of Casuarina glauca and Leucaena leucocephala seedlings [electronic resource].

Includes reference.

Four experiments were carried to cupitalize on rice strow as a mulch to ameliorate physical properties of the soil, exaggerate water use eficiency in addition to mineral input for growing of 3 months old Casvarino glauco and Leucaena leucocephaIa seedlings in two seosons at the Experimentol Station of Forestry and Wood Technology Department, Faculty of Agriculture, Alexandria University, Alexandria. and model nursery at Wadi El- Natroon Region, Beheira governorate. Egypt (from 2005- 2008). The first experlment was conducted 10 study the effect ofdepth ofstrow story on the growth and biomass of seedlings, using two depths, 10 cm (D₁₀) and20 cm(D₂₀) and unmulched soil (control). For both species studied. in both season, the results shewed that the mulched seedlings displayed growth and biomass higher than thnt ofunmulched ones. However, the deeper the mulch incorporated (D₂₀) in soil, the higher the growth and biomoss chararacteristics were obtained. The second experimelll wos done to study the impact ofinoculation with biTd's nest fungus (Cyathus stercoreus) on the growth and biomoss yield of seedlings, degradation rate ofthe strow and relative infiltration rate of rhizosphere. Fruit bodies ofe. stercoreus were upward emerged after/iJvr months ofinocultJtlon. Inocuiaied C. glauco seedlings displayed the highest shoot heighI, stem diameter, sheat growth rate, branchlets, roots and totul biomoss cumpared with uninoculted strow and control /realmellls. Inoculated Leucaena leucocepho1a seedlings displayed the highest growth and yield characteristics for both season. There were no signiflcalll differences between inoculaied and untnaculated ones in both of totol dry weighI of siem in the both season and values of both were higher than that of the control, but there were no signifuicant differences between inoculated and untnocuiaied ones.
