N2  - Investigations on the productivity of okra as influenced by crop combinations 
were conducted at the Vegetable Research Farm of the Department of Olericulture, 
College of Horticulture, Vellanikkara during 2000-2001. 
The experiment was laid out in randomised block design with three 
replications during two seasons. The base crop okra was raised at two different 
spacings along with intercrops amaranthus, cowpea and cucumber. Sole crops were 
also raised as control. Observations were made on growth characters, yield and 
yield attributing characters. Biological efficiency and economic suitability of the 
system were worked out using different indices. 
The results revealed that intercropping and spacing did not significantly 
influence the growth characters in okra, amaranthus, cowpea and cucumber. Yield 
per ha was higher at closer spacing of okra while the per plant performance was 
superior at wider spacing. Fruit characters like length, girth and single fruit weight 
of okra were not significantly influenced byspacing and intercropping. 
LER, LEC, ATER, aggressivity values and total biomass production 
revealed the biosuitability of okra based cropping system. LER was found to be 
more than unity in all the combinations, indicating the possibility of intercropping in 
okra. Aggressivity values clearly pointed out that cowpea and amaranthus were 
dominant over okra while cucumber was dominated. 
 
Economic analysis revealed that gross return, net return and per day return 
were highest for the combination of okra +cowpea at 60x45cm spacing. Effective 
weed suppression and reduction in pest incidence was also noticed in this system. 
Intercropping with cowpea led to a significant increase in the organic carbon and 
available nitrogen contents of the soil. 
Thus the study conclusively revealed the scope of recommending 
okra+cowpea at 60x45cm spacing as an economically viable, biologically suitable 
and sustainable cropping system to increase the productivity of vegetables.
