Abstract
Profiteering of Bio and Organic Fertilizers on Potato Production Under Drought Exertion
Highlights
Effect of inoculated potato plants with AMF (Glomus intraradices) and Pseudomonas fluorescens that interact with compost and mineral fertilizers NPK On Growth Parameter Under Three Irrigation Intervals: AM Colonization Percentage (%): The percentage of mycorrhizal root length colonization was estimated when plants were 60 and 90 days from germination
There were no significant differences between the values of AM inoculation as a single factor, as well as in the case of dual inoculation with AM and compost
The results showed significant differences between the dual inoculation (Glomus intraradices + Pseudomonas fluorescens) which values were (60.03, and 65.55) after 60 and 90 days, respectively, and the triple treatments (AM + Pseudomonas fluorescens + compost), had values were 64.07, and 68.55 after 60 and 90 days, respectively
Summary
Potato tubers (Solanum tuberosum) have been developed for over 6000 a long time.Currently, potato is one of the foremost momentous crops all over the world (Alamar et al.,2017), as it is grown for many purposes as food, industrial uses, and seed tuber production, depending on the locale, nation improvement, and historical reasons (Dolničar 2021).In Egypt, potato is considered one of the most important grown crops (Dewedar et al.,2021).Environmental conditions are serious limiting factors for growth and yield in crops, among these variables are drought, salinity stress, and extreme temperatures, which dehydrate the plant tissues and cause irreversible cellular damage and death (Bartels and Sunkar 2005).Drought is one of the most devastating stress factors that significantly lower crop productivity (Lambers et al.,2008).Arbuscular Mycorrhizal Fungi is an obligate soil fungi that can't be cultured in the absence of host plant roots (Nurbaity et al.2019). The symbiosis of plants with AM often increases nutrient uptake, accumulation of biomass, an increase in photosynthetic rates, and a decrease in root respiration and water use (Balliu et al.,2015). During stress conditions such as drought, AM fungus produces growth regulators that help the plant to cope with its environment; it has the potential to reduce plant stress by accumulation and immobilization of heavy metals in polluted soil (Boström 2020)
