%X effect of arachis pintoi on weed control associated with plantain (musa aab), cardenas, tabasco, mexico. the experiment was carried out in c¨¢rdenas, tabasco, mexico, in a soil with loamy texture, ph moderately acidic, low content of organic matter and total nitrogen, and cultivated with plantain. the objective was to evaluate the effect of arachis pintoi as a cover crop for weed control in plantain crops. the experimental design was factorial, housed in a randomized complete block, with shading and type of plantain plant cover as associated factors. three replications were used (october 2008-august 2009). both, the shading and the cover factors had two levels: 50 (s=¡À 13,2) and 45 %(s= ¡À 11.1), and the ground was covered by weeds and by a. pintoi respectively. shannon-wiever (h¡ä) and s£¿rensen (s) indexes were used to determine species richness. eleven months after the establishment of the experiment, h¡ä values did not differ significantly, s=0.8, in both shade percentages. the most common weed species were t. triangulare, s. podophylum, p. paniculatum and c. diffusa. the treatment with weeds and 50% of shade had statically the highest value of ms (375.3 ¡À 83.3 g/m2). ms produced by a. pintoi was statically higher (p=0,05) under 45% (198 g/m2) than under 50% shadea (150,4 g/m2). the effectiveness of a. pintoi in weed control was 52.3% under 45% shade, and 70.5% under 50% shade, respectively.
