Title: Yield Increase and Optimal Rate for a Processing Potato Variety by Applying Potassium Fertilizer
Abstract: Potato is one of the crops favoring potassium. In order to understand the feasibility of potassium fertilizer application on processing potato variety and optimal rate, the experiment was conducted to study the effects of potassium fertilizer and NPK combinations on yield increase of potatoes as well as the effects of different application rates of potassium sulfate on potatoyieldinorder toguidetheapplicationof potassium fertilizer onpotatousing'Atlantic' as experimental material. The results showed that potassium fertilizer and NPK combinations had significantly yield increasing effect on potato, with NPK combinations, NP combinations and no application in a decreasing order. In addition, the effects of different potassium application rateswasdifferentfrom eachother.When255kg/ha(K2SO4)wasused,potato yield and economic benefit werethebest.
