Abstract

Investigating the effect of urea and nano-nitrogen fertigation and foliar application of nano B and Mo on growth and yield of potato Solanum tuberosum L. [Rivera-A]. The study was conducted in a private farm located in the Al-Taleah area -Babylon governorate. The experiment consisted of (12) treatments consisting of separated fertigation of nano nitrogen (25% N) and urea (46% N), single treatments of leaf spraying of nano Mo (5%), Nano B (9%), nano-binary combinations (Mo+B) and (U+ Nano Mo), (U+Nano B), Nano (N+Mo), Nano (N+B), and tricombination treatments of (U+Mo+B), Nano (N+Mo+B) additional to the control treatment. Randomize Complete Block Design (RCBD) and one way simple experiment with three replicates.Fertilizers were applied at levels of 40 liters h-1 of Nano-N fertilizer (25% N) and 300 kg h-1 urea fertilizer (46% N). They were sprayed early in the morning after (40) days after planting four times. Two weeks is the period between an application and another according to the recommendation of (1) kg h-1 nano-fertilizer of (B) and (500) g h -1 of Mo. Fertilizers were injected and sprayed at (10, 20, 30 and 40)% of the total amount of the fertilizer were applied as the first, second, third and fourth applications, respectively. Some growth traits were tested including the chlorophyll content in the leaves, the total dry vegetative yild, the soft tubers yield, and the biological yield, proteins and ascorbic acid yield compared to the control (spray water only). The results of the Duncan test showed a significant increase in most of the studied traits of nano-tricombination (N+Mo+B) in the fresh tubers yield, dry vegetative yield , the biological yield, starch yield ,the total protein and ascorbic yield (37.

Plant growth promoting potential of urea doped calcium phosphate nanoparticles in finger millet (Eleusine coracana (L.) Gaertn.) under drought stress

“…In Sorghum bicolor (L.) Moench, application of the calcium nitrate-gelatin (CNG) coated urea showed maximum dry matter accumulation, high average plant chlorophyll content and apparent nitrogen recovery (ANR) of 71.14% in shoot and 4.5% in roots, respectively ( Khan et al., 2021 ). In Solanum tuberosum L., application of the nano-tri combination (N+Mo+B) increased chlorophyll content, the yield of the dry vegetative part, starch content, total protein and ascorbic acid ( Al-juthery and Al-Maamouri, 2020 ). In hydroponics also, Cucumis sativus L. supplemented with urea provides a maximum growth of root-shoot length and biomass of the plant ( Carmona et al., 2021 ).…”

Effect of NPS Fertilizer, Spraying Nano-NPK+TE and Cerium Oxide NPs on the Qualitative Properties and Bioactive Components of Rice Grains (Oryza Sativa L.)

“…By observing the results shown in Table No. (1) and Figure (4), that there are a significant improvement for the treatments at the trait of Oleic content in grains, with distinct of the treatment (NPS (200) + CeO 2 ) and achieved a significant value in comparing with the readings of other treatments by recording (10.310 %), and the other integrated treatments (NPS (200) +NPK +TE , NPS (300) +NPK +TE + CeO 2 , NPS (100) +NPK +TE , NPS (100) +CeO 2 , NPS (300) +CeO 2 ) also observed marked progress at Oleic unsaturated fatty acid with values (6.470, 6.150, 6.140, 5.420 and 4.850)% in comparing with the weakest treatment observed a reading of (2.610 %), Also, the single treatment of ground fertilization with (NPS) mineral fertilizer at level (300 Kg ha -1 ) gave notable progress in Oleic acid content with quantity of (6.670 %), while the treatments of foliar spraying of Nano-materials with (CeO 2 , NPK +TE ) reached a substantial value level of (6.340, 5.400)% respectively, and combined treatment (NPK +TE + CeO 2 ) was recorded value of (4.410 %).…”

“…From the results in Figure (4) we noted that the highest significant response of combined fertilizers at Linoleic acid content in the grains exhibited in the bi-treatment (NPS (300) +NPK +TE ) which observed a reading of (10.020 %) when comparing with the weakest treatment of (NPS (200) + CeO 2 NPs) observed a reading of (2.140 %), and the other combinations (NPS (100) +CeO 2 , NPS (100) +NPK +TE + CeO 2 , NPS (300) +NPK +TE +CeO 2 and NPS (100) + NPK +TE ) also noted an exceptional performance in Linoleic fatty acid by recording quantities of (9.770, 9.650, 8.690 and 5.040) %, respectively. While the single foliar spraying treatments (NPK +TE and CeO 2 ) showed values of percentage in Linoleic acid (6.390 and 5.380) % respectively, and also showed a significant increase in comparing with control treatment, significant values were also observed in the treatment with combined nanomaterials (NPK +TE +CeO 2 ) by recording (4.030 %) in comparing with the weakest treatment value, these results indicate that the increase in Oleic and Linoleic acids came as a result of the catalytic action of the producing reactions of unsaturated fatty acids, which may explain the abiotic tension that occurred on the rice plant as a result of spraying these nanocomposites.…”

“…Foliar spraying of Nano-nutrients can be a valuable method to supplement plant nutrition, enhance crop yield, and quality while decreasing environmental hazards like leaching, runoff, and toxicity [3]. The application of Nano-Nitrogen by foliar spraying can increase the nitrogen concentration in rice grains, improving the protein content and quality [4], also, Nano-Phosphorus is involved in energy transfer and cell division, and is a component of ATP, NADPH, phospholipids, and nucleic acids, and Nano-Potassium, plays a significant role in the process of photosynthesis by enhancing the efficiency of the enzymes involved [5], Potassium also contributes to the movement of leaf stomata, water balance, photosynthesis, and respiration.

Effect of Humic Acid and the Level of Nano and Conventional Nitrogen on the Available and Absorbed Nitrogen Element and the Potato Yield

“…Environmental risks resulting from the use of conventional fertilizers [6]. [7] conducted a study of the effect of administering urea and nano-nitrogen on the growth and yield of potato variety Rivera at the levels of adding 40 liters of nano-fertilizer ha -1 and 300 kg of urea ha -1 , where the nano-fertilizers had an effective role in obtaining highest score. Humic acid is one of the complex humic organic compounds that are important in plant growth, and its addition to the soil leads to a reduction in the use of fertilizers of major elements as well as reduces the loss of these fertilizers [8].…”
