Abstract EN

The experiment was conducted during the winter season 2017-2018 in one of the plastic houses of the research station of the college of Agriculture, Al-Muthanna University, in order to study the effect of the addition of peat moss of manure of cows, compost of water hyacinth and spray with nanoparticles of marine algae in the chemical content of the leaves of the okra plants ( Abelmoschus esculentus L.

(.

The experiment included (27) factorial treatments which were three levels of cow manures (0, 2, 4) kg.

m‾¹ and three levels of the compost of water hyacinth (0, 2, 4 kg.

m‾¹ and three concentrations of nano-fertilizers of the marine algae extract (0.5, 0.75, 1.5) m.

l‾¹.

Factorial experiment was carried out according to the split-split plot design in R.

C.

B.

D with three replicates.

The results were analyzed by the analysis of variance and mean values were compared using the Revised Least Significant Difference Test at 0.05 probability level.

The main results could be summarized as follows: Peat moss of manure of cows at the levels (2, 4) kg.

m‾¹ was significantly superior to control treatment in leaf content of nitrogen, phosphorus, potassium, total chlorophyll and total soluble carbohydrates (0.703, 0.714% ), 0.303, 0.286% , 285.3, 236.6 mg.

100 g ‾¹ fresh weight and 50.06, 52.43 mg.

100 g ‾¹ dry weight Respectively, while the 4 kg.

m‾¹ lwvel was significantly superior to control treatment in the content of leaves of nitrogen and potassium amounted to (4.826, 2.700% ) respectively.

Compost of water hyacinth at the levels (2, 4) kg.

m‾¹ was was significantly higher than control treatment of leaf content of nitrogen, phosphorus, potassium, total chlorophyll and total soluble carbohydrates by an increase of (15.68, 21.93% ), ( 40.00, 57.35% ).

(24.21, 43.25% ), (4.04, 7.39% ) and (9.00, 21.51% ), respectively.

Spraying with nanoparticles of marine algae at the concentrations of (0.75, 1.5) m.

l‾¹ had Significant increment in leaf content of nitrogen, potassium, total chlorophyll and total soluble carbohydrates, while the concentration of 1.5 m.

l‾¹ caused an increment in phosphorus and sodium concentrations compared to control treatment.

Most of the binary and triple interactions showed a significant effects on the studied characteristics.
