“…Among these, Zn sulphate and Zn oxides are the most commonly used Zn fertilizers around the world. The use of Zn oxide has recently increased due to its potential advantages to agriculture and especially crop production systems [ 38 , 39 ]. Zinc fertilization has a high response in the soil with low Zn concentration; grain Zn concentration is higher in the soils with low Zn fertility as compared to high Zn fertility soils.…”

“…Zinc is most commonly applied via mineral fertilizers such as zinc sulfate, zinc oxide, and chelates that significantly enhance plant growth, yield and Zn nutrition. In addition, foliar Zn fertilization counters Zn scarcity in standing crops, and Zn spray at the tasseling and milking growth stages improves grain development and grain Zn concentration [ 39 , 56 ].…”

The relationship between zinc mineral nutrition and plant growth-promoting bacteria (PGPB) is pivotal in enhancing agricultural productivity, especially in tropical regions characterized by diverse climatic conditions and soil variability. This review synthesizes and critically evaluates current knowledge regarding the synergistic interaction between zinc mineral nutrition and PGPB in tropical agricultural systems. Zinc is an essential and fundamental micronutrient for various physiological and biochemical processes in plants. Its deficiency affects plant growth and development, decreasing yields and nutritional quality. In tropical regions, where soil zinc availability is often limited or imbalanced, the PGPB, through different mechanisms such as Zn solubilization; siderophore production; and phytohormone synthesis, supports Zn uptake and assimilation, thereby facilitating the adverse effects of zinc deficiency in plants. This review outlines the impacts of Zn–PGPB interactions on plant growth, root architecture, and productivity in tropical agricultural systems. The positive relationship between PGPB and plants facilitates Zn uptake and improves nutrient use efficiency, overall crop performance, and agronomic biofortification. In addition, this review highlights the importance of considering indigenous PGPB strains for specific tropical agroecosystems, acknowledging their adaptability to local conditions and their potential in sustainable agricultural practices. It is concluded that Zn fertilizer and PGPBs have synergistic interactions and can offer promising avenues for sustainable agriculture, addressing nutritional deficiencies, improving crop resilience, and ensuring food security.

“…However, it was observed that the drought treatments using the 10 and 12-day irrigation intervals stimulated the production of antioxidants in plants, serving as a protective mechanism against the harmful effects of reactive oxygen species (ROS). Weisany et al, (2021) investigated the attributes and nutrient levels of maize plants under conditions of drought stress. The drought stress conditions were applied through irrigation intervals of every 8 days (non-stress), 12 days (moderate drought stress), and 16 days (severe drought stress).…”

This review endeavors to present a comprehensive overview of the current state of understanding regarding the ramifications of drought stress on the productivity of strategically important crops. It also delves into the positive effects of applying antitranspirants to plants subjected to drought stress. Moreover, this review seeks to explore the advantageous role of zeolite amendment in conserving irrigation water. By thoroughly analyzing the existing literature, this review aims to amalgamate and scrutinize the principal discoveries, emerging patterns, and research gaps up to the present time.The review will emphasize the imminent threats posed by water scarcity to the agricultural sector in Egypt and underscore the strategies for ameliorating the detrimental impact of water deficits through the reduction of irrigation water requirements. It will further examine the influence of water deficits on plant performance and highlight the efficacy of zeolite, employed as a soil conditioner alongside antitranspirants like kaolin and magnesium carbonate, in both conserving irrigation water and enhancing plant growth. Additionally, this review will pinpoint substantial challenges and prospects in the field, with the ultimate objective of guiding future avenues of research and pragmatic applications.

“…Nano-fertilizer reduces the use of synthetic fertilizers while increasing targeted nutrient availability for plant uptake and its intake by human in edible grains ( Prasad et al., 2017 ). Foliar application of nano-fertilizer has been widely reported for enhancing plant nutrition and productivity, as it enters the cell membrane more effectively, contributing to the metabolism of proteins, sugars, and amino acids, and photosynthesis of plants to increase nutrient use efficiency and reduce environmental constraints ( Weisany et al., 2021 ; Kandil et al., 2022 ). Foliar spray of ZnO is a more viable and prompt strategy than root/soil Zn application because of the large surface area and direct absorption through stomata and cuticles, and then translocation via the phloem into the chloroplast ( Su et al., 2019 ; Zhu et al., 2020 ).…”

Nanozinc and plant growth-promoting bacteria improve biochemical and metabolic attributes of maize in tropical Cerrado

et al. 2023

IntroductionPlant growth-promoting bacteria (PGPBs) could be developed as a sustainable strategy to promote plant growth and yield to feed the ever-growing global population with nutritious food. Foliar application of nano-zinc oxide (ZnO) is an environmentally safe strategy that alleviates zinc (Zn) malnutrition by improving biochemical attributes and storage proteins of grain.MethodsIn this context, the current study aimed to investigate the combined effect of seed inoculation with PGPBs and foliar nano-ZnO application on the growth, biochemical attributes, nutrient metabolism, and yield of maize in the tropical savannah of Brazil. The treatments consisted of four PGPB inoculations [i.e., without inoculation, Azospirillum brasilense (A. brasilense), Bacillus subtilis (B. subtilis), Pseudomonas fluorescens (P. fluorescens), which was applied on the seeds] and two doses of Zn (i.e., 0 and 3 kg ha−1, applied from nano-ZnO in two splits on the leaf). ResultsInoculation of B. subtilis with foliar ZnO application increased shoot dry matter (7.3 and 9.8%) and grain yield (17.1 and 16.7%) in 2019-20 and 2020-2021 crop seasons respectively. Inoculation with A. brasilense increased 100-grains weight by 9.5% in both crop seasons. Shoot Zn accumulation was improved by 30 and 51% with inoculation of P. fluorescens in 2019-20 and 2020-2021 crop seasons. Whereas grain Zn accumulation was improved by 49 and 50.7% with inoculation of B. subtilis and P. fluorescens respectively. In addition, biochemical attributes (chlorophyll a, b and total, carotenoids, total soluble sugar and amino acids) were improved with inoculation of B. subtilis along with foliar nano ZnO application as compared to other treatments. Co-application of P. fluorescens with foliar ZnO improved concentration of grains albumin (20 and 13%) and globulin (39 and 30%). Also, co-application of B. subtilis and foliar ZnO improved concentration of grains glutelin (8.8 and 8.7%) and prolamin (15 and 21%) in first and second seasons.DiscussionTherefore, inoculation of B. subtilis and P. fluorescens with foliar nano-ZnO application is considered a sustainable and environmentally safe strategy for improving the biochemical, metabolic, nutritional, and productivity attributes of maize in tropical Savannah regions.
