<br/><br/> The work was carried out at the Plant Protection Department, Faculty of Agriculture, AL-Azhar Univ, Nasr<br/>City, Cairo, Egypt. In order to carry outcomparative study between organic and mineral fertilization for mulberry<br/>trees and its effect on cocoon parameters of silkworm. Silkworm is a monophagous insect that drives almost all<br/>required nutrients for its growth and development from mulberry leaves. Treated mulberry Morusalbavarrosa<br/>(local variety) leaves were offered to Thiol of silkworm larvae four times per day. The obtained results showed<br/>that the feeding oflarvae on leavesmulberry of trees treated with green manure increased the fresh cocoon weight<br/>(0.796, 0.680g), cocoon shell weight (0.162, 0.,126g), pupa weights (0.678, 0.568g), cocoon shell ratio (24.98,<br/>23.1 Og), silk gland (0.361), cocooning percentages (89.6, 78%) and silk productivity (1.62, 1.29cg/days).
