Description
Con el propósito de conocer el impacto de la aplicación de fertilizantes foliares comerciales sobre el rendimiento de fruto de ocra (Abelmoschus esculentus), variedad ‘Clemson Spineless 80’, se realizaron estudios de campo en 1994 y 1995. En 1994 se evaluaron Carboxy y Foltron al follaje y Profit-G aplicado al suelo, así como sus combinaciones en suelo fertilizado. En 1995, los fertilizantes Carboxy, Foltron y Mora-Leaf se aplicaron al follaje en dosis altas y en suelo sin fertilizar. En todos los casos, se realizaron cinco aspersiones a intervalos de siete a 10 días iniciadas durante la primera semana de cosecha. En 1994, los tratamientos no mostraron efectos significativos sobre el peso de fruto, el rendimiento comercial de fruto y la altura de planta, comparado con el testigo. En 1995 no se observó influencia en la altura de planta y en el rendimiento de fruto. No hubo efecto de la fertilización foliar en el rendimiento de fruto en ocra.
Field studies were carried out during 1994 and 1995, in order to determine the impact of applying commercial foliar fertilizers on the ‘Clemson Spineless 80” okra fruit variety (Abelmoschus esculentus). Carboxy and Foltron applied on folliage, and Profit-G applied on the soil, as well as their combinations applied on fertilized soil were evaluated in 1994. Carboxy, Foltron and Mora-Leaf fertilizers were applied to folliage in high dosages and on non-fertilized soil during 1995. All plants were sprayed five times in 7 to 10-day intervals starting the first week of harvest. When compared to control plants, treatments applied during 1994 did not have a significant effect on fruit weight, fruit commercial yield and plant height. Treatments applied during 1995 did not influence plant height or fruit yield. The study proved that foliar fertilization does not have an impact on okra fruit yield.
