Interactive Effect of Biochar and Bio-Compost on Starting Growth and Physiologic Parameters of Argan

The argan tree, which is found in southern Morocco, characterized by environmental, economic and nutritional benefits, but the growth of this tree very slow. This makes it necessary to find methods accelerate its growth. A pot experiment was conducted evaluate effects biochar (BC) bio-compost (CP) each applied at rate 0, 3 6% (M/M) on starting fine silty soil for sixteen months. Main stem length, diameter, durability ratio, total length all stems number sprouted shoots were measured every two months with photosynthetic measurements spaced five apart seedling. Despite strong signs epigenetic sensitivity genetic variability across behavior treatment depending duration environmental conditions crop large standard deviations marked tests that argan, some treatments showed interesting results, even terms interaction between climatic conditions, type test. plants grown substrate BC 3% CP significant results parameters studied throughout mixture an average water holding capacity (WHC) around 0.66 g H2O/g dw; seedlings best perimeter average, exceeded 2.7 cm last measurement, a ratio (height/diameter) strictly less than 7, removes any possible problem filiform. However, from not stable characteristics studied; has advantages disadvantages regarding argan. Transplantation monitoring field have had are strongly recommended see if good influences their development or temporary effect.
