Investigation of pineapple fertilizing methods and Sower induction

Abstract

Greater yields were obtained from nitrogen supplied in urea sprays than in sidedressings. No differences in yield were obtained from the various rates and frequencies of urea spraying used. Solid urea side-dressings gave the same yield as ammonium sulphate side-dressings. Applying some nitrogen in the base-dressing gave no improvement in yield. A base-dressing of potash gave a higher plant crop yield but a lower ratoon crop yield than side-dressings of potash. Forcing produced a higher yield from all crops than did natural flowering. There were more fruit with forced flowering but their average weight was less.
