RESEARCH ON THE PRODUCTIVITY OF MAIZE INTERCROPPED WITH COMMON BEAN IN TWO SPATIAL ARRANGEMENTS, IN THE ORGANIC AGRICULTURE SYSTEM

Research was oriented towards studying the productivity and land equivalent ratio of maize and common bean in intercropping, in two spatial arrangements, in the organic agriculture conditions. The experiment was carried out in Moara Domneasca Experimental Field, on reddish preluvosoil, in randomised variants in 4 replications. The seed used in the experiment was obtained from ecological, material. It was sown a simple, early maize hybrid (Zea mays-DK 391) and common bean cultivar (Phaseolus vulgaris Diva cultivar). Maize was sown at 70 cm between rows and 28.6 cm between plants per row, at a density of 5 plants/m(2). Bean was sown between maize plants at a density of 2 plants/m(2) or between maize rows at a density of 12 plants/m(2). It was determined the productivity components, yields and land equivalent ratio, both for maize and for common bean.
