Development of Cultural Practices and
Environmental Control Strategies for the Production of Basil (Ocimum
basilicum L.) in a Semi-Arid Climate
Jennifer Nelkin, M.S.
Plant Sciences
The objective of this study
was to optimize the cultural and environmental conditions necessary to
produce high quality basil in a semi-arid climate during summer.
Basil grown in a retractable roof greenhouse (RRGH) and full sun over two
years using production systems including rockwool, containers, raised
beds, vertical towers, and soil was evaluated based on biomass
accumulation, morphological characteristics and quality.
Photosynthetic response of basil to temperature and light was tested in a
growth chamber to determine the optimum conditions that enhance
photosynthesis and increase productivity. Biomass accumulation and
quality of basil were affected by environment and cultural practices, with
the largest quantities of highest quality basil produced in rockwool or
raised beds in the RRGH. The response of basil to light and
temperature indicated that highest photosynthesis during summer occurred
between temperatures of 25 to 35 °C at a light intensity of 1500 µmol m-2
s-1.
