Effect of the Amount of Organic Inorganic Compound Fertilizer on the Yield and Quality of Winter Potatoes
Using Zuoshi No.1,one of the main potato varieties cultivated in Enping City,Guangdong Province,as the material,a randomized block design was used to study the effects of organic-inorganic compound fertilizer on potato yield,quality,etc. The aim was to provide theoret-ical basis for the rational use of organic-inorganic compound fertilizer in winter potato production in this area. The results showed that T3 treat-ment had significant yield increasing benefits,could ensure the quality of potato tubers,had the highest commercial potato rate,and the high-est economic benefits;and the partial productivity (119.84 kg/kg) and agronomic efficiency (67.10 kg/kg) of this treatment were both the highest.Taking into account potato yield,quality,fertilizer utilization rate,and economic benefits,it is recommended that 900 kg/hm2 of or-ganic-inorganic compound fertilizer be applied as a suitable fertilization scheme for winter potato production.
