Effect of rootstock, soil and foliar nutrition on minerals leaf content of local lemon saplings Citrus Limetta

Abstract

An experiment was conducted in the lath house affiliated to the Technical College AL-Musaib during the period from the beginning of March until the end of December, 2017 on seven months old local lemon saplings budded on the two root stock sour orange and sweet lime to study the effect of soil organic fertilizer feeding TARASOIL CALCIO with concentration(0, 50, 100)ml.L-1and foliar spray of DECSON with concentration of(0, 10, 20) ml.L-1to study the leaf content of minerals. The soil fertilization in 11/4/2017, 11/5/2017, 11/9/2017 and 11/10/2017, foliar spray in 74//2017, 7/5/2017, 7/9/2017 and 7/10/2017 , the experiment was applied by Completely Randomized Design(C.R.D) as factorial experiment(2×3×3) with three replication three sapling for every experimental unit, The results were analyzed using statistical analysis program(Excel). The averages were compared according to the least significant difference (L.S.D) at probability level of (0.05) the type of rootstock have a significant effect which, the rootstock of sweet lemon increased in, contents of the leaves of chlorophyll and elements: N, P, Ca, Fe, Zn and Protein while rootstock sour orange superior in Phosphor leaf contact. Interaction lime on rootstock +100 ml.L-1 TARASOIL CALCIO had a suppressive effect in leave content of chlorophyll and elements: N, P, K, Ca, Zn and Protein while rootstock of sour orange suppressive in content leaf of Fe. Rootstock of sweet lime +20 ml.L-1 DECSON had superion in content the leaf of chlorophyll and N, K, Fe ,Zn and Protein while Sour orange had a suppressive of P and Ca. sweet lime rootstock +100ml.L-1TARASOIL CALCIO+20 ml.L-1 DECSON, had significant effect in leaf content of chlorophyll and elements N, P, K, Ca, Fe, Zn
