Abstract
Basil ( Ocimum basilicum L.) is an herb commonly used as a flavoring additive for food. Its cultivation requires the selection of an adequate fertilization level that results in the greatest crop yield. This study evaluated the effects of four sub-recommended nitrogen fertilization levels [0, 21, 48 and 91 ppm N (mg·L −1 nitrogen)] on basil (cv. ‘Dark Opal’) growth, flower production, time of flowering, and leaf and stem N and C contents. The nitrogen fertilization level closest to the optimal rate (91 ppm N) produced plants with greater canopy weights, and more plants flowered than at the lower fertilization levels. However, plants fertilized at 21 ppm N were 14.7% taller and had about the same number of fully expanded leaves and branches, but with more flower clusters, than plants fertilized at 91 ppm N at 56 days after the initiation of the fertilization treatments. Growers may benefit from a lower-than-recommended nitrogen fertilization level (21 ppm N), which produced plants with more flowering clusters per flower head and with just as many leaves as higher nitrogen fertilization levels.

Claim · model-written summary
Authors suggest growers may benefit from 21 ppm N because it maintains leaves and raises flowering clusters.
