Impact of Potassium Nutrition on Fruit Yield and Physico-chemical Characteristics of Apple Cultivar Red Delicious

摘要

Field experiments were conducted in a randomized complete block design(RCBD)with four doses of potassium(K){2.5,3.0,3.5 and 4.0 kg muriate of potash(MOP)tree~(-1)} applied in two,three and four equal splits to access the effect of K on fruit quality of apple cultivar Red Delicious during 2015-16 and 2016-17.Results revealed that the K application @ 2.5 to 3.0 kg MOP tree~(-1)was optimum in producing quality fruits.Potassium applied in four equal splits improved the K use and had a significant benficial impact on the physico-chemical characters of the apple fruits.
