The results revealed that, the pH (8.03), plant height (160.5cm), highest number of shoots per plant (20.00), maximum leaf yield (56.78 t/ha/year) were recorded in sole mulberry, higher EC (0.275 dsm·1), organic carbon (0.56%), available nitrogen (256.65 kg/ha) in Mulberry and soybean, phosphor-us (48.05 kg/ha), potassium (189.42 kg/ha) recorded in mulberry and cowpea. The maximum leaf moisture in top leaves (75.23 %), chlorophy11 'a' ( 1.25 mg/ g) and chlorophyl1 'b' was (0.45 mg/ g) recorded in middle leaves mulberry and soybean intercrops. Highest number of pods (91.61) and Seed yield (972.30 kg/ha) was recorded in French bean intercropping with mulberry, Significantly more larval weight (38.36 g/ 10), ERR (91.6 %) and shorter fourth and fifth instar larval duration (5.13 days) and (6.92 days), better cocoon weight (19.38 g/10 cocoons), Pupal weight (15.86 g/10) and shell weight {3.51 g/ 10 shells) obtained in mulberry intercrop with soybesn and least she11 ratio percentage (15.46), filament length (734 m) and thicker denier (2.26 ) was obtained in sole mulberry. Least incidence of flacherie ( 1.33 %), grasserie ( 1.40 %) and muscardine (2. 75 %) was noticed in mulberry and soybean intercrops. Least number of weeds (8.71) were noticed in mulberry and green gram. Maximum net returns (Rs 26,086.10 ) and cost benefit- ratio (3.2 ) recorded in mulberry and French bean.ennullThesis
