Abstract: Bio-economic efficiency of different cotton-based intercropping systems was determined at the Agronomic Research Area, University of Agriculture, Faisalabad, (Pakistan) during 1996-97 and 1997-98. Cotton cultivar NIAB-78 was planted in 80-cm apart single rows and 120-cm spaced double row strips with the help of a single row hand drill. Intercropping systems were cotton alone, and cotton + mungbean. Experiment was laid out in a RCBD with split arrangements in four replications. Planting patterns were kept in main plots and intercropping systems in sub-plots. Intercrop was sown in the space between 80-cm apart single rows as well as 120-cm spaced double row strips. Competition functions like relative crowding coefficient, competitive ratio, aggressivity, land equivalent ratio and area time equivalent ratio were calculated for the assessment of the benefits of the intercropping. Partial budget was prepared for determining net field benefits of the systems under study. Growing of cotton in 120-cm spaced double row strips proved superior to 80-cm spaced single rows. Intercropping decreased the seed cotton production significantly in both years, however, intercrop not only covered this loss but also increased overall productivity. Higher net field benefit (NFB) was obtained from cotton + mungbean than sole cropping of cotton. Farmers with small land holdings, seriously constrained by low crop income can adopt the practice of intercropping of mungbean in cotton.
