Chitin and chitosan are natural compounds that biodegradable nontoxic have gained noticeable attention due to their effective contribution increased yield agro-environmental sustainability. Several effects been reported for application in plants. Particularly, it can be used plant defense systems against biological environmental stress conditions as a growth promoter—it increase stomatal conductance reduce transpiration or applied coating material seeds. Moreover, promoting chitinolytic microorganisms prolonging storage life through post-harvest treatments, benefit nutrient delivery plants since may prevent leaching improve slow release of nutrients fertilizers. Finally, remediate polluted soils the removal cationic anionic heavy metals improvement soil properties. On other hand, chitin also has many beneficial such promotion, improved nutrition ability modulate plants’ resistance abiotic biotic stressors.

Silicon (Si) is considered a non-essential element similar to cadmium, arsenic, lead, etc., for plants, yet Si beneficial plant growth, so it also referred as quasi-essential (similar aluminum, cobalt, sodium and selenium). An if not required by plants but its absence results in significant negative consequences or anomalies reproduction development. reported reduce the impacts of different stresses plants. The accumulation on tissue surface primarily responsible these positive influences such increasing antioxidant activity while reducing soil pollutant absorption. Because advantageous properties, application Si-based nanoparticles (Si-NPs) agricultural food production has received great deal interest. Furthermore, conventional fertilizers are have low bioavailability; therefore, development implementation nano-Si with high bioavailability could be crucial viable production. Thus, this context, objectives review summarize effects both Si-NPs microbes, growth various pathogens diseases. change microbial colonies biomass, influence rhizospheric microbes biomass content able improve fertility.

Published: Feb. 9, 2022

By 2050, population growth and climate change will lead to increased demand for food water. Nanoparticles (NPs), an advanced technology, can be applied many areas of agriculture, including crop protection enhancement, build sustainable agricultural production. Ionic gelation method is a synthesis microparticles or NPs, based on electrostatic interaction between opposite charge types that contains at least one polymer under mechanical stirring conditions. which are commonly chitosan (CS), have been fields, nanopesticides, nanofertilizers, nanoherbicides. The CS-NP CS-NPs-loaded active ingredients (Cu, saponin, harpin, Zn, hexaconazole, salicylic acid (SA), NPK, thiamine, silicon, silver (Ag)) effective in controlling plant diseases enhancing growth, depending the concentration application by direct indirect mechanisms, attracted much attention last five years. Many crops evaluated vivo greenhouse conditions but only maize (CS-NP-loaded Cu, SA, silicon) soybean Cu) were tested manage post flowering stalk rot, Curvularia leaf spot, bacterial pustule disease field condition. Since 2019, eight studies performed shown interest CS-NPs synthesized ionic method. In this review, we summarized current state research provided forward-looking view use management.

Nanomaterials as Nanofertilizers and Nanopesticides: An Overview

ChemistrySelect, Journal Year: 2021, Volume and Issue: 6(33), P. 8645 - 8663

Published: Sept. 1, 2021

Abstract Nanotechnology has acquired increasing interest recently in agriculture and crop production for achieving proficient utilization of resources by developing nanodelivery systems agrochemical products or sensors (for nutrient status water). The development new nanofertilizers provides a promising opportunity to improve plant mineral nutrition. According the reports, nanostructured materials are more efficient than traditional fertilizers, with site‐specific controlled release nutrients that not only increased efficacy uptake but also reduced negative environmental effects due loss into matrices. In this section, we illustrate various kinds novel as carriers such nanoclays, carbon nanodots, nanotubes, nanofibers, hydroxyapatite nanoparticles, carbon‐based nanomaterials, polymeric nanoparticles. Also, impact nanomaterials on pesticides is discussed. They play great contribution enhancing agricultural productivity involving gradual proper pesticide dosage aid pest control.

Foliage-Sprayed Nano-Chitosan-Loaded Nitrogen Boosts Yield Potentials, Competitive Ability, and Profitability of Intercropped Maize-Soybean

International Journal of Plant Production, Journal Year: 2023, Volume and Issue: 17(3), P. 517 - 542

Published: June 22, 2023

Abstract The progressive reduction of synthetic agrochemical fertilizers is one the key factors in shift from conventional agriculture to sustainable farming. Nitrogen (N) ruling element development agricultural production, but its use mineral form or excessive causes several environmental issues. Since release N nanocomposites coincides with their uptake by crops, loss reduces while enhancing plant due nano application. Additionally, an intercropping legume cereal as eco-friendly pattern could improve and rationalize nitrogenous inputs. Therefore, a two-year field trial was conducted determine efficacy nano-chitosan-loaded (CS-NNPs) for saving amounts applied maize-based on maize-soybean land productivity. Methods In randomized split-plot design three replicates, patterns, addition sole levels were implemented. Intercropping involved intercrop configurations [planting maize rows (M) alternated soybean (S) patterns 4M:2S, 2M:4S, 3M:3S)], planting crop (SMC) (SSC). fertilization treatments included adding 288 kg ha −1 (MN100%) two CS-NNPs composite involving 216 + 2 foliar sprays (MN75% 2CS-NNPs), 144 3 (MN50% 3CS-NNPs). Under tested treatments, agronomic traits, indices, economic benefits estimated. Results Findings revealed that application SMC × MN75% 2CS-NNPs, followed 4M:2S 2CS-NNPs showed highest growth, biological yield, grain yield maize. interaction SSC 2M:4S resulted seed components, straw soybean. Application MN100%, MN50% 3NNPs, 3M:3S MN100% recorded maximum total equivalent ratio. While applications achieved coefficient, land-use efficiency, area time ratio, percent difference. Likewise, both interactions system productivity index. Better advantage compared monocrop since actual values positive higher than zero all fertilization. Fertilizing 3CS NNPs grown under had aggressivity values. Conclusion shortfall accompanying 25% compensated CS-NNPs. Thus, intercropped soybeans can be rationalized. This undoubtedly has good payoff growers conservation environment. production systems, it advisable fertilize plants using instead nitrogen when chitosan-loaded twice (0.48 ) applied.
