Abstract: In order to investigate the effect of different fertilizers on peanut yield and quality in Northern Henan, field experiments were used to study the effects of four fertilizers(slow and controlled release fertilizer, long effect fertilizer,controlled release fertilizer, slow release fertilizer) and their application depth(10, 20 cm) on the agronomic characters, nitrogen(N), phosphorus(P) and potassium(K) nutrient accumulation and SPAD value, yield and quality of peanut. The results showed that, compared with the no fertilizer control, the application of different controlled release fertilizers could improve peanut agronomic characteristics, peanut nutrient accumulation, increase yield and improve quality.There was no significant difference in 100-pod weight, pod yield and seed yield among different fertilization treatments.The yield was the highest (7 083.5 kg/ha) under the shallow application of the slow release fertilizer.The main stem height and the 1st lateral branch length were the highest, and the pod yield was middle under of the shallow application of the slow and controlled release fertilizer. The deep application of slow and controlled release fertilizer had the highest kernel rate of 70.2%, the pod yield was 6 861.2 kg/ha, which was only next to the light application of slow release fertilizer, and the peanut kernel yield was 4 818.2 kg/ha. Slow and controlled release fertilizer had a significant effect on yield and quality of peanut. Compared with the control, the yield and crude fat content of peanut were increased by 30.43% and 5.18% under the deep application of slow and controlled release fertilizer. In terms of application depth, compared with shallow application, the accumulation of N,P,K increased by 8.49%, 9.54%, 0.28%, crude fat content and yield increased by 4.76% and 5.06% of slow and controlled release fertilizer deep application treatment. Considering comprehensively, deep application of slow and controlled release fertilizer was suitable for peanut growth and development and nutrient accumulation, thus improving the quality and increasing yield in sand loam in North Henan Province.
