Abstract
A single spray of ammonium thiosulphate (ATS) fertilizer applied when the spur flowers are approaching full bloom and lateral flowers are at about 50% of full bloom effectively reduced hand-thinning time and substantially improved fruit size of apricot in experiments conducted over a four year period. When applied as a gun spray to solution run-off, 0.4% and 0.5% ATS reduced hand-thinning time by at least one-third, increased fruit size by about 20%, and did not reduce branch and tree yields compared to control trees hand-thinned at the normal time. Airblast sprays also proved effective but the amount of wetting appears to be very critical to success. With mature plantations, 1500 to 1800 L/ha of 3% ATS gave satisfactory results. Information concerning the relative susceptibility of spur and lateral flowers and beneficial effects on fruit color and internal quality will be presented and discussed.
