Effect of Ground and Foliar Fertilization, Irration, and Cropload on Yield and Fruit Quality at Havrvest and After Cold Storage of 'Honeycrisp' Apple

Abstract

In 2002, an orchard with two experiments of 'Honeycrisp'/M.9 apple trees was planted at teh New York State Agricultural Experiment Station, Geneva, NY (2500 trees/ha). One experiment compared the effect of ground applied nitrogen fertilizer (100 kg N/ha) and potassium fertilizer (100 kg K20/ha), irrigation and cropload levels (1-5,6-10,11-15,>15 fruits/cm (exp 2) TCA) on yield and fruit quality. The second experiment compared the effect of three foliar sprays of N, B, Zn, and Mg in a ration of 1:0.15:0:5:0.14, irrigation and cropload on yield and fruit quality.
