EFFECTS OF FOOD FROM MULBERRY TREATED WITH UREA “N” ON LARVAL DEVELOPMENT AND COCOON WEIGHT OF SILKWORM BOMBYX MORI L.

Abstract

Silkworm larvae fed on leaves, from mulberry (Morus laevigata L.) tree, given soil treatment with 0.2%N concentration, consumed significant more food, gained more weight and produced heavier cocoons, as compared to those fed on leaves from trees treated with 0.1%N, 0.3%N, 0.4 %N concentrations.
