(23) In 1946 there was a program in the Rio Grande valley to substitute hybrid corn, which is produced by mixing several types of corn, for the native corn. The native corn was of poor nutritional quality and gave a poor quantity of grain, (24) while the hybrid corn was of excellent quality and gave about three times as large as a crop as the native variety. In the first year, half of the 84 farmers in the village planted hybrid corn and doubled the corn production. Three years later, however, only three farmers planted hybrid corn. The others were planting the traditional variety. At the beginning of the project the program leader studies scientifically the pattern of the natural relations of plants, animals, and people to each other and to their surroundings of the area and showed films demonstrating the superiority of the new corn.
The farmers agreed that the hybrid corn had great advantages. The size of the corn confirmed these advantages. Why did they stop planting it? (25) They complained that it wasn’t good for cooking and they didn’t like the flavor.
