| Abstract | ||
| A field experiment was carried out during two successive seasons (2018 and 2019) to evaluate the efficiency of P fertilization alone, in alternative with non-enriched compost tea (NECT) and together with enriched compost tea (ECT) at two application rates. The studied treatments were arranged within the experimental units in completely randomized block design. The effect of P treatments on soil chemical properties and its content of available nutrients, nodulation efficiency and soil productivity of common bean (Phaseolus vulgaris) plants and its content of essential nutrients was studied. Increasing rate of added P as H3PO4 in the three forms resulted in a decrease of soil pH and its content of CaCO3, slight increase of EC, and increase of soil CEC and its content of OM and available macro (N, P, K and Ca) and Micro (Fe, Mn, Zn and Cu) nutrients, where these changes were occurred with different rates. The high relative changes for the studied determinations were found with the treatment ECT P followed by those found in the soil fertigated by P+ NECT. Also, increasing rate of added P in the three forms resulted in increase in the formed root nodules, yield of common bean (straw and seeds) plants and its content of N, P, K, Ca, Fe, Mn, Zn, Cu and protein. As well as added P in ECTP followed by the applications of P+NECT increased the agronomical efficiency of P fertilizers under calcareous soil conditions. | ||
