The growth and yield attributing characters and yield of the crops. As the bio-metric parameters
and structural make up as well as morphology of the intercrops species differ widely due to their
genetic variations, statistical analysis of the intercrops were not done and only average value was
given in the Table.
Equivalent yield of the system: The rajmah equivalent yields of the different intercropping
system were calculated for each year individually and pooled analysis was done. The study
revealed that rajmah + lentil (1:1) ratio was the best treatment showing highest yield of 13.48 q
ha -1 which was at par with Rajmah +linseed (2:1): Rajmah +linseed (1:1) and Rajmah +lentil
(2:1) with a system yield of 12.83 qha -1 , 12.66 qha -1 and 12.59 qha -1 , respectively. The toria nad
buckwheat was not performing well with rajmah in both 1:1 and 2:1 ratio. For measuring of
biological efficiency of the intercropping, land equivalent ratio (LER) was calculated and it was
found that, linseed and lentil was more beneficial and economical as intercrop as compared to
toria and buckwheat.
The economics of different intercropping system was also calculated in terms of gross return, net
return and B:C ratio. Among the intercropping system of lentil and linseed, both the ratio of 1:1
ratio and 2:1 ratio is showing the B:C ratio more than 2 with a value of 2.58, 2.54, 2.50 and 2.50
each in rajmah +linseed (2:1), rajmah +lentil (1:1), rajmah +linseed (1:1) and rajmah +lentil (2:1),
respectively. The results can be supported by findings noted by Tripathi et al. where maize +
cowpea-wheat combination was the most productive and economic intercrop combination, with
an increase in net economic return (43.63%) and B: C ratio of 1.94.
Conclusion
Among the five different rabi crops studied to assess the best intercrops with rajmah it has been
seen that lentil and linseed was found to be more efficient and profitable than toria and
buckwheat. The highest land equivalent ratio, equivalent yield, and monetary advantage were
recorded in the rajmah + linseed intercropping of 2:1 ratio. The rajmah crop was not performing
well when intercropped with toria and buckwheat which is mainly due to the more height of the
intercrops resulting competition for light and others more particularly at early stage of growth of
the main crop rajmah.
