An experirnent was conducted to analyse the interspecies compatibility and Foduction potentials of mustard and lentil in intercrop association. The experiment comprised four planting systems viz., sole mustarq sole lentil, single row(l:l i.e-, one row of mustard followed by one row oflentil) and double row (l:2 i.e., one row ofmustard followed by two rows of lentil) intercropping. The stands height and number of branches (primary and secondary) per plant were maxirnum and minimum in sole and single row intercropped plants, rcspectively. Higher leaf area index and total dry matter production was observed in sole cropped mustad or lentil while lhose were lower in 1:2 interqopped mustard or I :l intercropped lentil plants. Maximum seed yield, 1.26 t ha-r (or I .30 t ha-r) was harvested from sole qop of mustard (or lentil) which was about 40 and 48% (or 34 atrd l2%) higher than that ofthe rnustard (or lentil) yield obtained ftom single and double row intercrop mixtures, respectively. Combined s€ed yield from double row mixture was the maximum ( I .8 t ha-r) and was respcctively I l, 30 or 28% higher than that obtained from single row intercropped stands, sole mustard or lentil. Single and double row intercropping systems respectively resulted 25 or 4l% increase in land equivalent ratios. Area time equivalency ratio was also increased by about 14 and 3l%, respectively for single and double row intercropping systems. The comp€titive ratio of each population is approached to be unity in both interqopping sysrems reflecting the proper balance of the natunl resources between associated species rcsultcd bettsr yield The results suggest that mustard and lentil populations are well compatible in intercrop association and l:2 row ratio mixture would be better for their profitable production.
