Abstract
A three-year study in central Wisconsin with timed foliar applications of maleic hydrazide at 3 lb/A (3.36 kg/ha) resulted in an improvement in quality and a favorable alteration in the shape of tubers of the Russet Burbank potato variety. Application in early and mid-July resulted in an increase in yield of U.S. 1 tubers and reduced yield of malformed tubers. Over 40 percent fewer misshapen tubers were produced when applications of maleic hydrazide were made during July when compared with tubers from untreated plants. Applications made in midor late July resulted in tuber development with a more favorable length to diameter ratio of U. S. 1 tubers, again compared with tubers from untreated plants. Maleic hydrazide applied in early or mid-June resulted in severely reduced yield and increased incidence of misshapen tubers. When applied in July or early August, no effect on tuber specific gravity was found. Maleic hydrazide functioned as an effective sprout inhibitor on tubers from all treatment dates except when applied in early June.
Resumen
Tres años de estudios en Wisconsin central con aplicaciones foliares espaciodos de hidrozida maleica (3 lbs/A) resultó en un mejoramiento de la calidad y una alteration en la forma de tubérculo de Russet Burbank. Tratamientos un julio, aumentaron el rendimiento de tubérculos.
Tamaños A, USI. Esto fue resultado de tipos de tubérculos fuera de graduación reducidos y malformados.
Algunos tubérculos tipo mancuerna y alagrimado (ápice agudo y cuello de botella) fueron producidos cuando las aplicación de hidrazida maleica fueron hechas en cualquier época de julio. Los tratamiento o la mitad y fines de julio resultaron en longitudes más favorables para el radio de tubérculos grado USI, comparados cori los testigos no tratados. La fecha de tratamiento tuvo poca influencia en el rendimiento de tubérculos de gran tamaño, excepto cuando fueron aplicados muy al inicio de la temporada. Tratamientos al inicio y mitad de junio redujeron severamente el redimiento y aumentaron los tubérculos deformados.
La hidrazida maleica aplicada después al final de junio, no tuvo efecto en la gravedad específica. La habilidad de inhibir el brotamiento de la hidrazida maleica no decreció con la epoca de aplicación, excepto con el tratamiento al inicio di junio.
