Abstract: To provide technical support for peanut high-efficiency fertilization on shajiang black soil in main peanut production area in southern Henan, a field experiment was conducted to study the effect of fertilization level on yield and quality of different genotype peanut varieties by split-plot randomized block design. The results showed that agronomic characters, economic characters and yield had significant difference among different peanut varieties; the yield of‘Yuanza 9102’,‘Yuanza 6’and‘Yuhua 22’was 5958.1, 5437.1 and 6008.6 kg/hm2, respectively, under conventional fertilization condition, increased by 18.4%, 14.9% and 13.7% compared with that of no fertilization; the oleic acid content, the ratio of oleic acid content and linoleic acid content in peanut kernel of‘Yuanza 9102’and‘Yuhua 22’were increased by fertilization, while these traits of ‘Yuanza 6’was reduced; crude fat content in peanut kernel and yield had significant difference among different peanut varieties,‘Yuanza 6’had the highest crude fat content and the lowest crude fat yield of 50.3% and 1873.3 kg/hm2;‘Yuhua 22’had the lowest crude fat and the highest crude fat yield of 48.6% and 1895.2 kg/hm2. Under the condition of N, P2O5, K2O application rates of 150, 90 and 150 kg/hm2, the pod yield and crude fat yield of‘Yuhua 22’were the highest, which was 6008.6 kg/hm2 and 2059.7 kg/hm2, respectively.
