Abstract: Using tomatoes as the test crop, field experiments were conducted during the rainy season in 1981-84 to evaluate the usefulness of: (a) plastic bags placed individually over each plant, (b) black plastic mulch and (c) plastic covered sheds. It was found that the plastic bags over each plant increased vegetative growth but retarded fruiting, thus depressing yield. (b) and (c) either had no significant effect or they both equally increased yield. Wet season yields from the same field could be as low as 13% of the dry season yield. ----- Experimentos de campo usando el tomate como el cultivo experimental, se lIevar6n a cabo durante la estacidn de lIuvias en los affos 1981-84, con el objeto de evaluar la utilidad de 10 siguiente: (a) bolsas pU:1sticas colocadas individuaJmente sobre cada una de las plantas, (b) plastico negro aJrededor de las plantas, (c) cobertizos cubiertos de plastico, SI~ encontro" que las bolsas plasticas colocadas sobre cada una de las plantas incremento el crecimiento vegetativo pero, retardo la fructificacion, por 10 tanto el rendimiento fue menor. Los puntos b) y c) 0 no tuvieron un efecto signiflcativo, 0 ambos de los usos incrementaron la producci6n, igualmente. Los rendimientos del mismo terreno, durante la estacion de lluvias, fueron a veces menos en un 13% que el de los obtenidos durante la estaci6n de sequia.
