Abstract: A study was conducted on the feasibility of suitable intercropping in new mulberry garden under irrigated condition at the Central Sericultural Research and Training Institute , Berhampore, West Bengal during the period from 2005 – 08. The season specific and short duration intercrops, two in each season viz, green gram and black gram (March – May), maize and cowpea (June-August), toria and pea ( Sept.- Nov.) and spinach and amaranth ( Dec.- Feb.) were grown in 1:1 and 1:2 rows within mulberry ( var. S-1635) planted in 60 x 60cm and 90 x 90cm spacing respectively. Maximum yield of intercrops as well as net profit per hectare were obtained in 90 x 90cm spacing with the combination of mulberry with green gram in March – May (Rs. 8344/-), mulberry with cowpea in June-August (Rs. 10,114/-), mulberry with toria in Sept-Nov (Rs. 4520/-) and mulberry with amaranth in Dec.-Feb ( Rs.7880/-) seasons over Rs.7442/-, Rs.8759/-, Rs.4320/- and Rs. 6963/- in 60 x 60cm respectively. Further, it also showed better benefit : cost ratio under 90 x 90cm spacing in all the seasons..
