“…At 30 DAS, the application of 100% RDN through Urea and 75% RDN with 25% nitrogen through Nano-N resulted in significantly more leaves, as did these treatments at the first and second cuts. The increase in the number of leaves may be due to the abundant supply of nitrogen through various nitrogen management practices, which could have increased protoplasmic constituents and accelerated cell division and elongation processes [18].…”

This study aimed to evaluate the efficacy of Nano nitrogen on various growth parameters of oats leads to growth and yield, including plant height, plant population, number of leaves, leaf length, leaf width, and the total number of tillers per plant. During the study, growth parameters were recorded at 30 days after sowing and after the I and II cuts. Results revealed that 30 days after seeding, applying 100% recommended dose of nitrogen (RDN) through Urea and 75% RDN with 25% nitrogen through Nano-N resulted in significantly greater plant heights as compared to the rest of the treatment combinations. Similarly, these treatments also had significantly higher plant heights during the I and II cuts. The number of leaves significantly increased with the application of nitrogen through all sources, either individually or in combination, highest number of leaves was observed when 100% RDN was applied through Urea or when 75% RDN was applied combined with 25% nitrogen through Nano-N. The leaf length and width of the oats were also significantly improved by nitrogen management practices, with the maximum leaf length observed when 100% RDN was applied through Urea or when 75% RDN was applied combined with 25% nitrogen through Nano-N. Similarly, the highest leaf width was observed with the application of 100% RDN through Urea at all stages, while 75% RDN + 25% Nano-N was comparable to 100% RDN through Urea. The number of tillers per plant was significantly affected by different nitrogen management practices at 30 days after sowing and after the I and II harvests, highest number of tillers per plant was observed through the application of 100% RDN through Urea. Overall, the results show that the use of Nano nitrogen can significantly improve the growth attributing characteristics as well as yield attributes and yield of oats, particularly when combined with traditional nitrogen sources. These findings are consistent with previous research in this area.

In this study, Brassica chinensis L seedlings after 6 weeks of soil cultivation were treated with foliar application of TiO2 NPs (20 mg/L) for different times. Transcriptomics analysis was employed to investigate the impact of TiO2 NPs on the physiology, growth, and yield of B. chinensis L. Results showed that TiO2 NPs’ exposure significantly increased the biomass, total phosphorus, and catalase enzyme activity by 23.60, 23.72, and 44.01%, respectively, compared to the untreated ones (not bulk or ion).TiO2 NPs increased the leaf chlorophyll content by 4.9% and photosynthetic rate by 16.62%, which was attributed to the upregulated expression of seven genes (PetH, PetF, PsaF, PsbA, PsbB, PsbD, and Lhcb) associated with electron transport in photosystem I and light-harvesting in leaves. The water balance of B. chinensis was improved correlating with the altered expressions of 19 aquaporin genes (e.g., PIP2;1 and NIP6;1). The expressions of 58 genes related to plant hormone signaling and growth were dysregulated, with notable downregulations in GA20, SnRK2, and PP2C and upregulations of DELLAs, SAM, and ETR. Moreover, the 11 tricarboxylic acid cycle genes and 13 glycolysis genes appear to stimulate pathways involved in promoting the growth and physiology of B. chinensis. This research contributes valuable insights into new strategies for increasing the yield of B. chinensis.
