The use of aerial photography as a survey tool for estimating misses in potato crops proved satisfactory. The average crop had 32% misses; in six of the 25 crops the misses were more aggregated than expected assuming a binomial distribution. An estimated loss of 10% in tuber yield resulted from the misses, and based on the 1973 crop value the loss was equivalent to approximately $4 million. Eighty-eight percent of the 1,000 misses investigated were due to the seed piece being absent.

El uso de fotografia aérea como herramienta para el reconocimiento de lagunas en cultivos de papa resultó ser satisfactorio. Un cultivo promedio resultó tener 32% de langunas; en seis de 25 cultivos las lagunas fueron más agrupadas de lo esperado asumiendo una distributión binomia. Una pérdida estimada del 10% en rendimiento de tubérculos fué ocasionada por las lagunas, lo cual basándose en el valor de la cosecha para 1973 fué equivalente a aproximadamente $4 millones. El 88% de 1000 lagunas investigadas fueron el resultado de la ausencia de semilla.
