EFFECT OF PLANT DENSITY AND ESTABLISHMENT METHOD ON SUCKER PROMOTION IN 'KEW' PINEAPPLE BY MECHANICAL DECAPITATION |
| Author: | H.M.S. Heenkenda |
| Abstract:
Mechanical decapitation is an appropriate multiplication method for pineapple in Sri Lanka. Sucker production employing this method can be increased by using high mother plant densities in the nursery. Plant densities in the nursery were varied from 25000 to 83000 pl/ha using single or double row plantings. The time taken for the first sucker to appear was significantly affected by the plant density. The shortest time recorded was 58.5 days at densities of 51200–58000 pl/ha, irrespective to the method of establishment. The time taken for the second-sucker to appear was not significantly affected by the density. Plant density and single or double row planting systems did not significantly affect the time taken to produce suckers of suitable size for field planting (300–400g in fresh weight). Mean number of suckers/plant also was not affected by the treatments. Total sucker count/ha increased with increasing density up to 76000 pl/ha. | |
