Corral de Piedra and Salitron are two communities located in the municipality of San Juan Ermita, which is in the department of Chiquimula, Guatemala. In both communities, the land has very sloped topography with slope grades ranging from 12 to 55%. Agriculture is the main production activity with corn (Zea mays L.) and beans (Phaseolus vulgaris) being the crops of greatest economic importance. These crops are planted through a system of sequential association commonly called relay. First, corn is planted at the beginning of the rainy season (May or June). Once it has completed its reproductive cycle, beans are planted in an intercalated fashion between corn plants (Zea mays L.). The harvest of both takes place in December. An important factor in increasing the production of any crop is fertilization. In the above-mentioned communities, the use of commercial fertilizer is common. However, each producer applies only the amount he can afford according to the cost at the market, not the amount the crop actually requires. For this reason, the corn variety ICTA B-1, which can reach yields of 3,250 kg/ha, was evaluated in the experiment. Our objective was to evaluate different doses of fertilizer. The study was done in 1999 during the period when winter is constant (June to September), which is the season when small producers of grain plant their crop. In regard to performance, the dose that responded best was 65-26-0 N-P-K which produced 5,865 kg/ha. In addition, it got a marginal rate of return of Q76.6 per quetzal (Guatemalan currency) invested in increasing the variable costs invested in cultivation. The Institute of Agricultural Science and Technology (ICTA) recommends this dose for the region.
