Mineral and organic fertilization in the intercropping associated corn-bean and bean in an Andosol of the State of Mexico

Abstract

Agricultural production in San José del Rincón, State of Mexico, as in the country in general, presents environmental, economic and social problems. The implementation of technologies not adapted to local conditions has reduced the productivity of peasant systems. The objective was to evaluate the productivity, Relative Efficiency of the Land (REL) and family net income of the intercropping in fringes of corn-associated guide bean and beans in an Andosol, with mineral and organic fertilization. The research was conducted on a producer's plot in the spring-summer cycle of 2014. The experimental design was divided into plots with two topological arrangements (TA) as a large plot (a groove of corn-bean associated guide, interleaved with a bean groove (1x1), and two groves of associated corn-bean guide, interspersed with two bean grooves (2x2)) and nine small-plot treatments, selected with a one-factor matrix at a time (Baconian matrix) The factors were: fertilization, population density and variety of corn. Three simple culture treatments were added to calculate the relative efficiency of the land. The results indicated that the intercropping 1x1 with blue corn and the 2x2 with pink corn; fertilization 80-80-00 with 3tha-1 of compost, obtained a relative efficiency of the earth of 1.35 and 1.40 respectively, with an income equivalent to 1.8 and 1.24 minimum wages per day. It is concluded that the intercropping of maize-beans associated with bean increases the yield and income on the simple crop and is an option for t e farmers.
