Agriculture is considered a significant climate change (CC) driver due to greenhouse gas (GHG) emissions and the loss of fertilizers that contribute water eutrophication. On other hand, effects are already impacting agriculture, endangering food security. This paper explores dichotomies agriculture on CC as well focusing contribution nanofertilizers can bring this complex system in both directions. The strategies reduce while adapting mitigating its must be global effort. It not possible focus only reduction GHG stop being felt worldwide. Nanofertilizers, especially slow- controlled-release nanofertilizers, nutrient input also boost productivity some effects, such soil imbalance agricultural emissions.

Abstract Increased impetus on the application of nano-fertilizers to improve sustainable food production warrants understanding nanophytotoxicity and its underlying mechanisms before could be fully realized. In this study, we evaluated potential particle size-dependent effects soil-applied copper oxide nanoparticles ( n CuO) crop yield quality attributes (photosynthetic pigments, seed nutrient quality, protein, oil), including root Cu bioaccumulation a suite oxidative stress biomarkers, in soybean Glycine max L.) grown field environment. We synthesized three distinct sized (25 nm = S [small], 50 M [medium], 250 L [large]) CuO with same surface charge compared soluble 2+ ions (CuCl 2 ) water-only controls. Results showed photosynthetic pigments (Chla Chlb), yield, potassium phosphorus accumulation seed, protein oil yields, CuO-S showing higher inhibitory effects. Further, increased led concomitant increase (H O , MDA), as response, several antioxidants (SOD, CAT, POX, APX) proportionally, treatments ion treatment.

Maize (Zea mays L.) is an important crop grown for food, feed, and energy. In general, maize yield decreased due to drought stress during the reproductive stages, and, hence, it critical improve grain under drought. A field experiment was conducted with a split-plot design. The main factor irrigation regime viz. well-irrigated conditions withholding from tasseling filling 21 days. subplots include six treatments, namely, (i) control (water spray), (ii) zinc oxide @ 100 ppm, (iii) manganese 20 (iv) nZnO ppm + nMnO (v) Tamil Nadu Agricultural University (TNAU) Nano Revive 1.0%, (vi) sulfate 0.25% 0.25%.

Compound microbial fertilizer is a new type of environmentally friendly slow-release that can effectively improve the physical and chemical properties soil, significantly ecological environment, promote sustainable development agriculture. In this study, we conducted field experiment to evaluate impact different applications combined with composite on soil soybean yields at Heshan Farm, Heilongjiang Province, China, during 2021–2022. Soybean varieties “Jinyuan 55” “Keshan 1” were treated three treatments implemented as follows: T1 (conventional fertilization), T2 (50% N + compound fertilizer), T3 (0 fertilizer). Compared conventional fertilization (T1 treatment), application fertilizers (T2 T3) resulted in decrease bulk density an increase porosity. Notably, observed moderate (T3) led volume fraction clay particles sand particles. Furthermore, all exhibited high content agglomerates larger than 5 mm 0–20 cm. The promoted formation large reduced presence micro-agglomerates smaller 0.25 mm. 2021–2022, yield increased by 13.02% treatment compared decreased 9.34% treatment.

The Violaceae family is rich in metal-tolerant species and producing cyclic peptides (cyclotides) that are linked to the resistance biotic factors. Plants inhabit areas polluted with heavy metals have developed various mechanisms of tolerance. To test role cyclotides protection against abiotic factors, including metals, cell suspension cultures Viola species/genotypes (V. lutea ssp. westfalica, V. tricolor, arvensis, uliginosa), representing different levels tolerance (from most tolerant-MET least tolerant populations/species-NMET), were used. relative abundances control, untreated suspensions all selected species/genotypes, cells treated Zn or Pb (200 µM 2000 µM) for 24 h 72 determined via MALDI-MS.

Globally, biological soil crusts (BSCs) are crucial ecosystem components that perform essential functions important to stability. However, the potential mechanisms of BSC's effect on vascular plant recruitment and establishment largely unknown. Furthermore, few studies have considered BSC‐vascular analyses in conjunction with BSC microenvironments, seed traits, life stages simultaneously. Thus, we chose six typical plants different traits Loess Plateau conducted a growth chamber experiment evaluate effects types, disturbance, seeding positions, moisture germination, survival, seedling growth. We also explored presence disturbance emergence through field investigation. The results indicated main four factors, type, location, moisture, their two‐ three‐dimensional interactions had significant performance most studied species. Disturbance wetting treatments shorter watering intervals promoted plants, could modify BSCs plants. was related stage promotes when it reaches survival stage. In observations, found number species lower compared bare lands broken greater than intact crusts; while density land significantly higher patches.
