Biological N Fixation and N Transfer in an Intercropping System between Legumes and Organic Cherry Tomatoes in Succession to Green Corn

The aim of this study was to investigate the transfer N from different legumes cherry tomatoes in intercropping system under residual straw previous green corn crop using 15N natural abundance method. We also investigated temporal variation nitrogen a tomato, biological fixation (BNF) legumes, and concentration cultivated intercrop succession. experimental design complete randomized block with eight treatments five replications, described as follows: two controls consisting monocrop tomato or without straw, jack bean, sun hemp, dwarf velvet mung white lupine cowpea bean system. BNF responsible for more than half accumulated legumes. transferred similar quantities, leaves fruits received shoots. It shown that increases growth/development tomatoes. did not affect aboveground biomass
