The developed-fruits rate varies from 9.97 % in productive "dkar" to 11.5 % in "lanta" while aborted-fruits percentage remained lower (6.58 % and 7.03 % for "lanta" and productive "dkar" in the same order). Moreover, productive "dkar" category presents a regular production of carobs whereas the "lanta" one shows an altemate fructiferous production from one year to the next.
