Influence of foliar application of some nano-fertilizers in growth and yield of potato under drip irrigation

Abstract

A field experiment was conducted in Autumn planting season 2018 at the Fields of In section 158 of the district 41 Husseiniya Province of Babylon, to investigate the influence of foliar application of Nano chelate silicon fertilizes (NSF), Nano chelated potato specific fertilizer (NPS) and Nano chelated complete micro(NCM) on growth and yield of potato variety Riviera. Foliar applied at 50, 100, 150 and 200 g or ml of all nanofertilizer types 100 L−1 water or 2 kg nanofertilizers ha−1 (as recommended) dissolved in 400 liters of water ha−1.The experiment included spray of single (NSF), (NPS), (NCM), di (NS+NPS),(NS+NCM),(NPS+NCM), and tri combinations (NS+NPS+ NCM), in addition to control (only water) using RCBD with 3 replicates. Growth and yield parameters tested were chlorophyll, dry matter, vegetative yield, fresh tubers yield, biological yield, starch, crude protein, ascorbic acid, AE(Agronomic efficiency) and WUE (Water use efficiency). The results showed that tri combination (NS+NPS+NCM) spray treatment was significantly higher followed by the di and single spray combinations. Fresh yield, dry tubers, vegetative yield and biological yield were (42.130, 9.327, 2.901 and 12.228 Mg ha−1) respectively, compared with the control (28.440, 5.453, 2.240, and 7.693 Mg ha−1), respectively. Tri combinations (NS+NPS+ NCM) starch content, crude protein and ascorbic acid concentration (vitamin c) were (17.10 %, 9.08% and 185.33 mg kg−1 f.w.), compared with the control treatment (12.22%, 7.79% and 136.33mg kg−1 f.w.).

Effect of Urea and Nano-Nitrogen Fertigation and Foliar Application of Nano-Boron and Molybdenum on some Growth and Yield Parameters of Potato

“…Nano-fertilizers increase the availability of ready-made nutrients to the plant, longer and by suitable release in line with plant growth that increases the formation of chlorophyll, the rate of photosynthesis, dry matter production, consequently, the overall plant growth. These results are similar to those obtained by [27] when potato crop was foliar fertilizers with nano-SMP (NPK + TE) and seaweed extract under drip irrigation. These results are also consistent with the results obtained by [28] when studying the effect of Nano-nitrogen fertigation on potato yield.…”

Effect of Spraying Some Nano-Fertilizers and Their Combinations on the Growth and Yield of Fenugreek (Trigonella foenum-graecum L.)

“…It is also noted from Table (2) that there is a significant effect of spraying nano-fertilizers and their combinations on the characteristic of the total number of leaves of the plant, The plants treated (T10) significantly outperformed all treatments and produced the highest average of 69.71 leaf.seedling -1 , and the lowest average was recorded in (T1) treatment, which amounted to 50.93 leaf.seedling -1 . The reason may be due to the Synergistic Effect between the ground addition of a balanced NPK fertilizer containing balanced proportions of the major elements, the role of the chelating synthetic nanofertilizers for the major and minor elements, and their high penetration efficiency, absorption speed, transport and representation [19] [20], which increased the photosynthesis activities Which reflected on the increase in the biomass of plants.…”

The Impact of Bio-Organic and N, P, K Fertilizers on the Growth and Yield of Potato

“…This may also due to the role of bio-fertilizers and mineral fertilizers because they contain nutrients such as where they are available to absorption after mineralizing it in the soil due to soil revitalization and this leads to improving vegetative growth, thus an increase in the yield [16,17].…”
