Influence of Using Compost Tea Enriched with Spirulina Plantensis Algae on Fruiting of Balady Lime Trees.

Abstract

The response of Balady lime trees (citrus aruntifollia) to application of inorganic N as well as compost tea enriched with Spirulina plantensis Algae was investigated during 2010 and 2011 seasons.Results revealed that supplying the trees with recommended nitrogen rate (RN) through 75 % inorganic form plus 50 to 200 ml compost tea at 20 % per tree and Spirulina plantensis at 25 ml per tree was preferable more than using inorganic N alone at 75 to 100 %of the recommended rate in improving growth characters, nutritional status of the trees as well as yield, both quantitively and qualitatively of Balady lime trees. Application of compost tea enriched with spiruling plantensis surpassed than using compost tea alone in this respect.Supplying Balady lime trees with RN (800 g/ tree/ year) through 75 % inorganic N + 100 ml compost tea 20 %/ tree + 25 ml spirulina plantensis Algae/ tree is suggested to be beneficial for improving yield and fruit quality. Introduction:Nitrogen fertilization is considered an important and limiting factor for fruiting of citrus crops

Biofouling mechanism and cleaning procedures for Spirulina platensis as an organic fertilizer draw solution

“…The microalgae Spirulina platensis was studied as a possible fertilizer by different researchers (Masoud Alaa et al 2012 ; Aung 2011 ; Faheed and Fattah 2008 ; Dineshkumar et al 2018 ; Sridhar and Rengasamy 2002 ). From an agriculture point of view, microalgae Spirulina platensis can improve soil structure by increasing the amount of organic matter and stimulate the activity of soil microorganisms (Masoud Alaa et al 2012 ; Aung 2011 ; Faheed and Fattah 2008 ; Dineshkumar et al 2018 ; Sridhar and Rengasamy 2002 ; Jimenez et al 2020 ). Wuang et al ( 2016 ) explored the usage of spirulina as a fertilizer in combination with aquaculture effluent.…”
