Effect of Nano Chelated Nitrogen and Urea Fertilizers on Wheat Plant Under Drought Stress Condition

Abstract

This study was performed to evaluation of nano chelated nitrogen and urea fertilizers on wheat plant under drought stress condition. Experiments were carried out in two locations in Fars province, Iran. Experimental design was performed as split-split plot in RCBD design. The first factor included irrigation treatments (normal and withholding irrigation at flowering stage), sub factor was nitrogen treatment (0, 37, 74 and 110 kg.ha -1 ) in the form of Urea fertilizer, and sub-sub factor was nitrogen (0, 14, 27 and 41 kg.ha -1 ) in the form of nano chelated nitrogen fertilizer. Studied traits included stem weight, spike weight, spike length, plant height, tiller number, stem diameter, anthocyanin, flavonoid, proline, soluble carbohydrates, chlorophyll a and b, carotenoid, 1000-seed weight, biological yield, seed yield and harvest index. According to analysis of variances, stress, nitrogen (urea) and nano chelated nitrogen had significant effects on all studied traits. According to mean comparisons, drought stress led to 51% reduction in seed yield compared to normal irrigation. Application of 37, 74 and 110 kg.ha -1 urea led to 9, 19 and 27% increase in seed yield compared to control, respectively. Application of 14, 27 and 41 kg.ha -1 nano fertilizer led to 31, 44 and 98% increase in seed yield compared to control, respectively. In interaction between stress, urea and nano fertilizer on seed yield, was found that at normal and stress condition the highest mean of seed yield (7591 and 4091 kg.ha -1 ) was obtained by 110 kg.ha -1 urea and 41 kg.ha -1 nano fertilizer. In conclusion replacing urea by nano chelated nitrogen can increase the yield even in the drought stress and decrease amount of needed fertilizer.

Impact of N-nano fertilizer on yield attributes, economic and quality of pearl millet (Pennisetum glaucum L) under rainfed condition

“…Application of RDN (T 2 ) recorded significantly the lowest length, breadth and weight of ear head, grain yield plant -1 and grain yield (kg ha -1 ). The results of this investigation are consonance with the findings of Al-juthery et al (2018) [1] and Astaneh et al, (2018) [2] , and Salama and Bandry (2020) [9] . The maximum harvest index (31.84%) was recorded with the application of 75% RDN through urea as soil application + 25% RDN through 1 spray of nano-urea (45 DAS) (T 5 ) which was found at par with the application of 75% RDN through urea as soil application + 25% RDN through one spray of urea (45 DAS) (T 8 ) and 50% RDN through urea as soil application + 50% RDN through two spray of nano-urea (30, 45 DAS) (T 4 ) (Table 1).…”

Site-Specific Fertilizer Management through Nutrient Expert: Productivity, Profitability and Efficiency of Wheat

“…The higher nitrogen concentration of grain and straw with increasing nitrogen rate might be due to the crop's having adequate nitrogen, which could enhance nitrogen concentration on biological yield, particularly straw, due to better roots and greater density. These is in line with the findings of Worku et al (2007) and Astaneh (2018) who reported that increase in the supply of nitrogen increases straw nitrogen content gradually.…”

Impact of Preceding Crop, Sowing Methods and Nano-Fertilizer (Amino mineral) on Bread Wheat Production and Quality in Toshka Region, Egypt

“…Furthermore, the application of NP S improves carbon balance in crops, accelerates plant growth, can increase the efficiency of micro and macronutrients of plants, and reducing the use of chemical fertilizers per unit area which causes environmental problems (Mahil & Kumar, 2019;Hasan & Saad, 2020). Most of the researches conducted globally on nano-fertilizers suggest that these materials have a greater role in crop production with environmental safety, ecological sustainability and economic stability, the same as reported by Abdel-Aziz et al (2016) Astaneh et al (2018) found that Nano Chelated N is the best fertilizer due to the significant yield increase of wheat in lesser doses. Fertilization with NPK NPs produced an increase in yield for wheat (Abdelsalam et al, 2019).…”

“…13, 22.90 and 30.86%, 4.31, 7.78 and 10.08% , 4.33, 7.29 and 10.34% and 13.41, 29.03 and 40.71% in the same order compared to control treatment (NF 1 ). Application of 14, 27 and 41kg ha -1 nano-fertilizer led to 31, 44 and 98% increase in seed yield compared to control (Astaneh et al, 2018). Fertilization with NPK NPs produced an increase in yield for wheat (Abdelsalam et al, 2019).…”
