Abstract:
With the purpose of regulating the crop load,
several low biuret urea concentrations (4,8,12%
and 12,16 and 20%) in two following years were
sprayed during full bloom on 'Armking' and
'Springred' nectarines and 'Springcrest' peach.
One month after the treatment a complementary
hand thinning was carried out in order to adjust
the fruit load.
The degree of thinning was
floral-stage-dependent and the best results were
obtained at 122 dosage.
Trees sprayed with
concentrations higher than 12% snowed toxic
symptoms whereas those treated with solutions
containing less than 12% of urea did not differ in
crop load from the control plants.
