Nitrogen rate and frequency affect ketembilla in the nursery
Nitrogen (N) is often applied in excess in fruit crop nurseries, possibly with negative effects to the environment and the plants being fertilized.
A nursery study was conducted to assess the effects of N rates and frequency of application on the growth of ketembilla (Dovyalis hebecarpa) plants in the nursery.
The treatments were nitrogen rates (0.2 to 1.2 g N plant‑1) applied as drench at two frequencies, every 7 or 14 days.
After 140 days of the first N application, plant height, SPAD values and leaf area were significantly greater in the regimen of 0.4 g of N applied every 7 days.
Increasing N rate or frequency of application did not further enhance ketembilla growth or became detrimental to the plant.
These results may assist in designing rational N fertilization programs for ketembilla in the nursery.
