The effect of foliar application of nano-organic fertilizer and proline acid and their interaction In some The vegetative characteristics of Moringa oleifera Lam

Abstract

This study was carried out in according to completely randomized design(CRD) in one of the private nurseries of the city of Ramadi / Anbar Governorate during the agricultural season of 2019. the aim of study was to determine the effect of nano-organic fertilizer and proline acid in some of the vegetative growth characteristics of Moringa oleifera . The study included three concentrations of nano-organic fertilizer (0, 50, 100) mg. L -1 and three concentrations of proline acid (0, 100, 200) mg. L -1, with three replicates, and after applying the studied factors and the passage of five months from the germination date : data were collected for the studied characteristics , statistically analysed , and the means were compared using the least significant difference (L.S.D) at the probability level 0.05. The results showed that spraying with organic fertilizer gave significant differences in the mean of the studied traits, since the treatment T1 achieved a concentration of 50 mg.L -1 (Plant length, leaf area, stem diameter, and dry weight of shoots ) either treatment T2 at a concentration of 100 mg. L -1 gave the highest rate in the two characteristics leaves number and dry weight of roots . As for spraying with proline acid, the treatment achieved T3 at a concentration of 100 mg. L -1 the highest rate in the two traits of dry weight of the vegetative group and stem diameter and treatment T4 at a concentration of 200 mg. L -1 achieved the highest rate in the rest of the other characteristics, namely (plant height, number of leaves, leaf area and dry weight of the Root) .The results also showed that the interaction between the organic fertilizer and proline concentrations achieved significant differences in some of the studied traits , as T6 treatment included 100 mg . L-1 of nano-organic fertilizer and 100mg. L-1 of proline acid gave the highest rate in plant height , number of leaves , leaf area and dry weight of shoots and roots .
