Percent crude protein of maize was high with maize-mungbean intercropping, thus, maize and mungbean are compatible crops for protein production. High maize fodder yield was associated with high leaf area index (LAI) and crop growth rate at high maize population density. Yield of intercropped mungbean significantly decreased with increased maize population. Double row planting of maize at an interval distance of 1.5-2.0 m improved mungbean growth and gave higher seed yield. Intercropping mungbean with sugarcane was found to be an efficient method for food and2048forage production. It gave additional amounts of high quality herbage. An intercrop population of 800,000 ha to the minus 1, thinned down to 200,000 gave sufficient fodder yield without adversely affecting either the sugar or the mungbean grain yield. High crude protein percentage, crude protein yield, and in vitro dry matter digestibility were attained when thinning was done at 35 DAS, suggesting that this is the best stage to harvest the mungbean fodder. The high intercrop yield with double row planting is primarily attributed to the large interval row space of the intercrop. Double row biotectural arrangement did not affect the sugar yield. Increased degree of leaf defoliation in sugarcane resulted in more fresh fodder and high dry matter yield. Complete or 75% defoliation significantly decreased sugar yield, tonnage yield, and yield components. Defoliation leaf fodder when mixed with intercrop mungbean was found to be a good source of livestock feed. Sugar and tonnage yield and their components were not affected by the detopping treatments. Detopped forage yield (2.9 t/ha to the minus 1) did not vary with detopping date. Detopped fodder can support 3.27 ruminant animal for 120 da
