Tifton 85 production under deficit irrigation
Deficit irrigation consists of application of amounts of water less than plant requirements for satisfying water deficiencies of the crop, and this may maximize efficiency of water use.

Deficit irrigation consists of application of amounts of water less than plant requirements
for satisfying water deficiencies of the crop, and this may maximize efficiency
of water use. The aim of this study was to evaluate the effect of deficit irrigation on
production of Tifton 85 grass. The experiment was carried out on the Santa Helena
Farm in the municipality of Bom Despacho, MG, Brazil. Five levels of irrigation were
used as treatments (28%, 42%, 57%, 71%, and 85% of the crop coefficient value) in
randomized blocks with three replications. The following variables were evaluated: dry
matter production (kg ha-1), leaf/stem ratio, height (cm), dead plant material (%), leaf
area index, leaf area ratio (m2 kg-1), leaf weight ratio (kg kg-1), and specific leaf area (m2
kg-1). A difference was observed for Tifton 85 production in which the greatest average
yield (6126.35 kg ha-1) was obtained through application of 71% Kc. For the other
characteristics, there was no difference for any of the variables evaluated. El riego deficitario consiste en la aplicación de láminas inferiores a las necesarias para satisfacer las deficiencias hídricas de un cultivo, además que puede maximizar la eficiencia en el uso del agua. El objetivo de este trabajo fue estudiar el efecto del riego deficitario en la producción del cultivo Tifton 85. El experimento fue realizado en la Hacienda Santa Helena situada en el municipio de Bom Despacho, Minas Gerais (MG) Brasil. Los tratamientos utilizados fueron: cinco láminas de riego (28%, 42%, 57%, 71% y 85% del valor de coeficiente de cultivo) en bloques aleatorios con tres repeticiones. Fueron evaluadas las siguientes variables: producción de materia seca (kg ha-1), relación hoja/altura, altura (cm), materia muerta (%), índice de área foliar, relación de área foliar (m2 kg-1), relación de peso foliar (kg kg-1) y área foliar especifica (m2 kg-1). Se observó una diferencia en la producción de Tifton 85, donde el mayor promedio de producción (6126.35 kg ha-1) se obtuvo con la aplicación de las láminas 71% Kc. Para las demás características no hubo diferencia en ninguna de las variables estudiadas. |
