Engineering factors affecting on basil growing [electronic resource].

Includes bibliographic reference.

This study was carried out to measure and manage the operational parameters of the hydroponic system.
A series of experiments were conducted to examine various parameters, including the effects of four
different levels of operating pressures (0.50, 0.75, 1.00 and 1.25 bar), four different levels of
root zone temperatures (16, 22, 28 and 34 oC), and basil seedlings that were two weeks old on oxygen level,
herb production, water productivity, and power consumption. The results show, the best production conditions ware ,
Basil age 45 days, the root zone temperature, 28 °C , and operating pressure was 100 kPa ( 1bar).
The results also show that, The maximum dissolved oxygen concentration of 6.8 mg/L, 90.66 leaves,
a plant height of 24.20 cm, a stem diameter of 4.68 mm, and a total weight of 17.30 g/plant for the leaves.
Basil's longest root length was 64 cm, at 22 °C in the root zone and operating pressure was 100 kPa (1bar).
The maximum quantity of essential oil was 2.8% and highest Basil's water productivity was 0.3 kg/m3 at the root
zone temperature, 28°C.
