Irrigation and Drainage Series, Volume 6, No. 1-2: 29-38, 1983, Cuba.
The influence of irrigation on the Marsh grapefruit yield at Youth .Isle, in a lixiviated yellow quartz ferrallitic soil was studied. The irrigation time was determined by the gravimetric method.It was found that in the Marsh grapefruit, the best response to irrigation was obtained by maintaining soil moisture at the limit of 75% of field capacity in the period before flowering and 85% of field capacity after flowering. Under the conditions of study the effect of irrigation on yield depends on the frequency, volume and application time. In the grapefruit yield in a given year is influenced by the residual effects of the above
