EFFECT OF NPK AND ORGANIC FERTILIZATION AND IRON AND ZINC PAPER SPRAYING BASED ON NANOTECHNOLOGY AND NORMAL METHODS IN THE GROWTH AND YIELD OF SOLANUM TUBEROSUM L.

An experiment was carried out at the Research Station of the Faculty of Agriculture, University of Baghdad for the 2017 spring season by planting Solanum tuberosum L. (class Burren) on 6 of February 2017 in a mixed soil to determine the effect of adding NPK, organic fertilizer levels as well, iron and zinc paper spraying, and their interactions in the growth and yield of potatoes. Randomized complete Block Design (RCBD) was used in experiment with three-replicates each containing 30 treatments. The experiment included three factors: NPK fertilizer levels (M0) without fertilization, (M1) half of the fertilizer recommendation 50% (160: 40: 120) kg KPN h^-1, (M2) complete fertilizer recommendation 100% (240:80:320) kg KPN h^-1 and levels of organic manure (poultry) were O0 without fertilization, O1 add 20 Mg h^-1 organic fertilizer. The Levels of iron and zinc paper spraying with regular fertilizers and fertilizers manufactured according to nanotechnology were F0 without spraying with iron and zinc, F1 was sprayed with iron and zinc at a concentration of 50 mg Zn^-1 + 100 mg Fe^-1, F2 was sprayed with 100 mg Zn L^-1 + 200 mg Fe^-1 using standard compost (EDTA- Zn 14%) and EDDHA-Fe 6%). The levels (F3 and F4) represent the irradiation of iron and zinc produced according to nanotechnology at a concentration of 50 mg Zn^-1 + 100 mg Fe^-1 and 100 mg Zn^-1 + 200 mg Fe^-1 respectively, using fertilizer (Chelate Zn 20% and Chelate Fe 10 %). The results showed that the single and double addition of NPK, organic fertilizer, and iron and zinc paper spraying had a significant effect on the dry weight of the vegetative group, the average weight of the tuber, the total yield and the percentage of germination relative to the comparison treatment. The results indicate that the triple interaction, which were the addition of 50% of the M1 fertilizer recommendation, the addition of the level of organic fertilizer O1 and the spraying of iron and zinc produced according to the nanotechnology (F3 and F4), gave the best value for the growth traits and productivity in the quantity and quality. The M1O1F4 treatment exceeded the total dry weight of total vegetative, the average weight of the tuber and the total number which reached (2.62 Mg^-1, 106.89 g and 41.15 Mg^-1), respectively. The M1O1F3 treatment was superior to 13.24%, with an increase of 70.40% compared to the M0O0F0 comparison. The study showed that half the amount of fertilizer recommendation from mineral fertilizers could be compensated through organic fertilization and paper spray with iron and zinc produced according to nanotechnology and get the best productivity both qualitatively and qualitatively.
