Growth and yield promoting effect of artificial mycorrhization on field tomato at different irrigation regimes

Yield and water use of cherry tomato under water availability and potassium doses

“…The effect of water availability on the shoots was similar to that found by Candido et al (2015), who observed an increment in tomato shoot dry matter as water depth increased. Bowles et al (2016) also studied tomato under deficit conditions and (3) availability levels, the data fitted to a linear regression model, with highest number of fruits (58 fruits plant -1 ) found at tension of 44 kPa, an increment of 45% in comparison to the tension of 4 kPa ( Figure 2B).…”

“…Kuşçu et al (2014), Candido et al (2015), Bogale et al (2016) and Bowles et al (2016) worked with tomato under water deficit condition and also observed reduction in yield.…”

“…Mycorrhizal inoculation increased the above ground total biomass in AM plants by 4%, 34%, and 9% in IR 0 , IR 50 , and IR 100 respectively compared to Control plants (Fig. 2), and this in compatible with (Lekberg et al, 2005;Ortas et al, 2013) additional mycorrhization enhances the growth in field crops, and in processing tomato (Bakr et al, 2017;Candido et al, 2015). The growth enhancement is related to better nutrient (Augé, 2001) and water (Ruth el at., 2011) uptake from the soil.…”

“…This symbiont relationship backs up tomato plants to avoid water lack stress (Bakr et al, 2017;Candido et al, 2015), while the host plant supplies the fungus with photosynthates and an ecological niche. The improvement direct and indirect water uptake by AMF (Ruth et al, 2011), is also accompanied by enhancement in nutrient acquisition and uptake especially phosphorus (P), leading to better water retention in plant, enhanced physiological functions, and better growth (Augé, 2001; more efficiently under dry soil conditions (Neumann and George, 2004).…”

“…The improvement direct and indirect water uptake by AMF (Ruth et al, 2011), is also accompanied by enhancement in nutrient acquisition and uptake especially phosphorus (P), leading to better water retention in plant, enhanced physiological functions, and better growth (Augé, 2001; more efficiently under dry soil conditions (Neumann and George, 2004). Further inoculation with commercial inoculum did enhance crop productivity and colonization rate, with no quality improvement (Bakr et al, 2017;Candido et al, 2015). In tomato, antioxidants composition is affected by abiotic factors such as irrigation, temperature, and light (Pék et al, 2014), but mycorrhization could improve lycopene and β-carotene in fruits (Ulrichs et al, 2008).…”
