Field experiments were conducted at the Experimental Farm, Annamalai University, Annamalainagar to study the effect of spacing, vermicompost and intercropping on the yield and economic of baby corn during kharif and summer 2007. The experiments were laid out in split-split plot design with three main treatments viz., sole baby corn (C1), baby corn + cowpea (C2), baby corn + blackgram (C3) and two sub-treatments viz., 60 x 15 cm (M1), 45 x 25 cm (M2) and three sub-sub treatments viz., recommended NPK (150:60:40 NPK kg ha-1) (S1), recommended NPK + vermicompost @ 5 t ha-1 (S2), recommended NPK + FYM @ 12.5 t ha-1 (S3) replicated thrice. The highest net income of ` 44563 and 42574 ha-1 and benefit cost ratio of 4.25 and 4.11 were obtained in baby corn intercropped with cowpea in kharif and summer, respectively. Adopting a spacing of 60 x 15 cm gave the highest net income of ` 55163 and 53227 ha-1 and benefit cost ratio of 4.51 and 4.39 in kharif and summer, respectively. The application of recommended NPK + vermicompost @ 5 t ha-1 resulted in realization of the highest mean net income of ` 60727 and 58985 ha-1 and benefit cost ratio of 4.65 and 4.55 in kharif and summer, respectively. The lowest net income and BCR was accounted in sole crop of baby corn with normal spacing and recommended fertilizer schedule.
