The biological efficiency indices LER, LEC, ATER, aggressivity and RCC were worked out for
the system in both planting systems. LER and ATER for all the treatments were above one and this
indicated that intercropping in ash gourd is biologically efficient. The LEC value was highest for ash
gourd + amaranthus (T4) and ash gourd + bush cowpea (T3) combination. Negative aggressivity
values for treatments containing three crop combinations indicated that the intercrops could be more
aggressive, but there is no yield reduction in the base crop, ash gourd.
