Twenty four bearing trees of Pineapple sweet orange of same age and vigour were selected and fertilized during early spring at the rate of 500-173-207.5, 1000-327-415 g NPK/tree/year and control. Higher NPK doses improved concentration of elements in fruiting as well as non-fruiting terminals. Phosphorus content remained unaffected. Among the tagged inflorescences, single flowers on current shoots gave significantly better fruit yield. A positive correlation was found between leaf N and K in spring flushes and fruit yield.
