Studies on Nutrition of Pineapple Iv. Effect of Source of Nitrogen and Potassium on Yield and Quality of Pineapple*

A trial was land out for finding out the best source of nitrogen and potassium on Kew variety of pineapple at Kushalnagar during the year 1969. Ammonium sulphate, Calcium ammonium nitrate and urea were the nitrogen sources and potassium chloride and potassium sulphate for potash. The data indicated that ammonium sulphate was the best source of nitrogen for increasing fruit yield and suckers and slips production. There was no difference between potassium chloride and potassium sulphate. Ammonium sulphate and potassium chloride was the best combination followed by ammonium sulphate and potassium sulphate. Calcium ammonium nitrate with potassium sulphate caused low fruit weight and less plant material production.
