The perennial overstorey component 'mango' was managed by drip irrigation system while annual groundstorey component 'toria' was raised under rainfed conditions. At initial stage, overall growth of mango plants was not much influenced when toria was grown as an intercrop in comparison to sole plantation of mango. About 3.68 q ha-1 (average of 1996 and 1997) grain yield of toria was obtained under gravely rainfed conditions. The yield of toria was highly influenced by distribution of rains during growing period. There was no significant effect of direction on the yield of toria but negative response was recorded at close proximity with tree canopy due to shade effect. There were significant differences in dry matter and grain yield of toria under varying topsoil depths, which increased with increasing depth of topsoil. The net income of about Rs.3000/- ha-1 annum-' can be obtained by growing toria as intercrop with mango orchard under gravely rainfed conditions. The model needs long term testing for interaction effect among components and on site productivity.Not Availabl
