Effect of ground fertilization with Vermicompost and spraying with Moringa leaf extract on some vegetative growth traits of Lime saplings (Citrus aurantifolia).

Abstract

The study was conducted in one of the private nurseries in Babylon province for the period from September 2020 to June 2021 to study the effect of fertilization with Vermicompost and spraying with Moringa leaf extract and the interaction between them on the growth of lime saplings. 144 sapling of homogeneous growth were selected as much as possible with age of one year. The experiment included adding Vermicompost fertilizer with four concentrations (0, 10, 20, 30) g. sapling^-1, and four levels of spraying with Moringa leaf extract (0, 50, 100, 150) ml.L^-1, the results can be summarized as follows:

The addition of Vermicompost treatment (V3) was excelled and gave the highest averages in the studied traits (increment in leaves number, increment in branches number, leaves area, chlorophyll content and carbohydrates) reached (226.20 leaf sapling^-1, 7.23 branch sapling^-1, 8266 cm² sapling^-1, 50.14 mg 100g^-1 fresh weight, 6.41%).The treatment of Moringa extract (B2) excelled and gave the highest averages in (increment in leaves number, increment in branches number, leaves area, chlorophyll content and carbohydrates) (225.70 leaves.sapling^-1, 6.25 sapling. branch ^-1, 8194 cm ² sapling ^{- 1}, 45.20 mg 100 g^-1 fresh weight, 6.25%).In terms of the best treatment between them, the combination of V3B2 has excelled and gave the highest averages for the above traits.
