Corn-faba bean associations in the Peruvian Central Andes

Abstract:

In the communities of the Central Andes of Peru, faba bean and corn seeds are mixed at sowing, resulting in random mixed crops. The proportion of the respective seeds can vary considerably from one year to another. In this system, farmyard manure is the main source of fertilization (1348-10300 kg ha-1), sometimes extended with limited inorganic fertilization (23-67 kg ha-1 N). From 2006 to 2008, 19 bean-corn plots were investigated at farm level in different farmer communities of the Mantaro Valley, Central Andes, Peru. NPK and C balances due to the different corn-bean proportions and fertilization levels were evaluated. Moreover, in 2011, an experiment with different area proportions of corn-bean was set up to try to optimize production. Measured biomass varied considerably, depending on sowing proportion, plant density, fertilization level and harvest stage. At harvest, the fresh weight of corn cobs and bean …
