The Influences of Water Availability and Vesiculararbuscular Mycorrhizal (VAM) Fungi on Growth and Physiological Processes of Tomato (Lycopersicon Esculentum Mill.) in Soilless Culture

| Summary: | A study was conducted to determine the influence of water
availability and vesicular-arbuscular mycorrhizal (V AM) inoculation on
growth and physiological changes of tomato. Two-week old tomato
seedlings were transferred to cultivation slab (120 cm x 30 cm)
containing 6 kg of coconut coir dust mixture (CD-Mix) media and allowed
to grow for two weeks before uniform plants were chosen for treatment.
The experiment was a single factor experiment arranged in a Complete
Randomized Design (CRD) with different levels of VAM inoculated at 0,
10, 20, 30 and 40 g per plant with four replications. Data was collected
at one week after treatment and subsequently at by-weekly interval until
the 7th week. Plants inoculated with the highest level of inoculum (40 g) resulted
in significant higher vegetative growth (as measured by shoot and stem
dry weight) and physiological processes (relative water content and
stomatal conductance). There was a significant linear relationship
between the number of fruits (y=234.094 + 1.215x) and the total soluble
solids (y=5.603 + 0.038x) with the rate of inoculum used.
V AM at 40 g per plant was further evaluated using a split plot
arrangement in Randomized Completely Block Design (RCBD), with water
availability (WA) as main-plot (100%, 75%, 500/0 and 25% of moisture
content: based on substrate water holding capacity) and V AM inoculation
(MI) as sub-plot. Data was collected at weekly interval (4 weeks) after
treatment. |
