Abstract: A field experiment was conducted under irrigated conditions during 2007-08 at Main Agricultural Research Station, University of Agricultural Sciences, Dharwad, to study the mulberry based vegetable intercropping systems, its potential yield, mulberry fodder quality and economics. The soil texture of the experimental site was sandy loam and was low in available nitrogen (173.6 kg/ha), available phosphorus (14.8 kg/ha) and medium in available potassium (153.8 kg/ha). There were 11 treatments with 10 paired mulberry and one normal planting of sole mulberry treatments. In paired mulberry (120 cm and 150 cm), there were 8 treatment combinations with 4 vegetables intercropped and two were paired sole mulberry. The cumulative mulberry fresh shoot yield was significantly higher in mulberry (60/120 x 30 cm) sole (17.2 t/ha) compared to rest of the treatment combinations except mulberry (60 / 120 x 30 cm) + peas which recorded significantly on par cumulative mulberry fresh shoot yield (16.6 t/ha). Among the intercropped treatments, significantly higher vegetable yield of carrot (3.23 t/ ha) was recorded in mulberry (60/120 x 30 cm) + carrot compared to rest of the vegetable intercropped treatments. However, french bean (2.37 t/ha) intercropped with 120 cm paired mulberry was on par with peas (2.27 t/ha) intercropped with 120 cm paired mulberry and carrot (1.82 t/ha) intercropped with 150 cm paired mulberry. Significantly higher mulberry equivalent yield of mulberry based vegetable intercropping systems (57.5 t/ha) was recorded in mulberry (60/120 x 30 cm) + peas compared to rest of the treatments. Significantly higher crude protein, ether extract and total ash content of mulberry on whole plant dry weight basis (19.0 %, 3.23 % and 10.8 %, respectively) was recorded in mulberry (90 / 150 x 60 cm) sole. Significantly lower crude fibre content of mulberry (15.9 %) was recorded in mulberry (60 /120 x 30 cm) + french bean. Significantly higher mean mulberry fodder palatability (87 %) was recorded in mulberry (60/120 x 30 cm) + field bean Significantly higher gross returns (Rs.77,753 /ha), net returns (Rs.26,744 /ha) and benefit cost ratio (1.52) was obtained in mulberry (60 / 120 x 30 cm) + peas intercropping kharif by utilizing mulberry for fodder kharif and silk worm rearing during rest of the year in the first (establishment) year of mulberry cultivation.
