Abstract
Stem thinning was tested on a collection of seedlings and varieties covering a range of maturities to see if an economic increase in tuber size could be induced.
Thinning to one stem did not improve yield of marketable tubers. Plants thinned to two stems showed some improvement since yields from two varieties and three seedlings exceeded the checks by an average of 8%; however, these amounts were not statistically significant.
Resumen
Se ha ensayado el deshije de tallos en una colección de brotes y variedades de varias edades con el fin de averiguar si es posible de inducir un incremento economicamente remunerativo en el tamaño de los tubérculos.
Deshijando hasta dejar un tallo único no resultó en mayor rendimiento de tubérculos de buena calidad. Plantas deshijadas hasta dos tallos dieron alguna indicación de incremento ya que los rendimientos obtenidos de las dos variedades y tres brotes excedieron los controles en un 8% en promedio; sinembargo esto no fué estadisticamente significante.
