الملخص EN

This study was conducted to find out the effect of adding mineral fertilizers with N, P, and K traditional and spraying nano-Fertilizers of N, P and K on the tubers content of nitrogen, phosphorous, potassium and some qualitative characteristics of potatoes.

A field experiment was conducted in one of the agricultural fields assigned to the Faculty of Engineering Sciences.

The agricultural sector in Jadriya for the spring season 2018-2019 in a texture of sandy clay loam soil.

The first two factors included five levels of mineral fertilizer S0 without adding fertilizer and S1 addition 1/4 recommendation for fertilizer and S2 addition 1/2 Fertilizer Recommendation and S3 Addition 3/4 Fertilizer Recommendation and S4 Addition of the full fertilizer recommendation and the second factor spraying with three nutrient solutions F0 spraying with water and F1 spraying with regular fertilizer and F2 spraying with nanoparticles.

The sectors are completely randomized with three replications.

Sifra seed potatoes were planted on February 4, 2019, at maturity, the amount of N, P and K in tubers, on May 25.

In 2019 the tubers were uprooted, the mineral fertilization treatment (S4) outperformed the rest of the mineral fertilization treatments in the study indicators, as the nutrient concentrations in the tubers reached 2.09.

Phosphorous is 0.26, potassium 2.46% , starch content of 16.34% , and protein 13.09% .

The treatment of spraying with nanoparticles F2 showed superiority in the study indicators compared to the two spraying treatments F0 and F1, as it gave 1.77% , 0.22% and 2.22% concentrations of nitrogen, phosphorus and potassium in Tubers and starch ratio 14.09% and protein 11.07% .

interaction treatment S4F2 gave the highest values of the study indicators amounting to 2.23, 0.29 and 2.54% concentrations of nitrogen, phosphorus and potassium in tubers, 18.58% and 13.94% , both starch and protein respectively.
