“…Zinc plays important physiological roles in maize and its deficiency can reduce grain yields by up to 10% (Joy, Stein, et al, 2015 ). Several studies report a positive response of maize grain yields to the application of Zn fertilizer (Manzeke et al, 2014 ; Palai et al, 2020 ; Stewart et al, 2021 ). For example, Liu et al ( 2020 ) reported maize yield increases of about 4% to 17% with soil application of Zn fertilizer in China.…”

Zinc (Zn) deficiency remains a public health problem in Malawi, especially among poor and marginalized rural populations, linked with low dietary intake of Zn due to consumption of staple foods that are low in Zn content. The concentration of Zn in staple cereal grain can be increased through application of Zn‐enriched fertilizers, a process called agronomic biofortification or agro‐fortification. Field experiments were conducted at three Agricultural Research Station sites to assess the potential of agronomic biofortification to improve Zn concentration in maize grain in Malawi as described in registered report published previously. The hypotheses of the study were (i) that application of Zn‐enriched fertilizers would increase in the concentration of Zn in maize grain to benefit dietary requirements of Zn and (ii) that Zn concentration in maize grain and the effectiveness of agronomic biofortification would be different between soil types. At each site two different subsites were used, each corresponding to one of two agriculturally important soil types of Malawi, Lixisols and Vertisols. Within each subsite, three Zn fertilizer rates (1, 30, and 90 kg ha −1 ) were applied to experimental plots, using standard soil application methods, in a randomized complete block design. The experiment had 10 replicates at each of the three sites as informed by a power analysis from a pilot study, published in the registered report for this experiment, designed to detect a 10% increase in grain Zn concentration at 90 kg ha −1 , relative to the concentration at 1 kg ha −1 . At harvest, maize grain yield and Zn concentration in grain were measured, and Zn uptake by maize grain and Zn harvest index were calculated. At 30 kg ha −1 , Zn fertilizer increased maize grain yields by 11% compared with nationally recommended application rate of 1 kg ha −1 . Grain Zn concentration increased by 15% and uptake by 23% at the application rate of 30 kg ha −1 relative to the national recommendation rate. The effects of Zn fertilizer application rate on the response variables were not dependent on soil type. The current study demonstrates the importance of increasing the national recommendation rate of Zn fertilizer to improve maize yield and increase the Zn nutritional value of the staple crop.

“…Earlier research [ 5 , 14 , 26 , 27 ] revealed the mitigation effect of either Zn or PBZ on salt injury in different plants. The stimulating effect of Zn under normal or stress conditions is dedicated to accelerating the photosynthesis processes and accelerated photoassimilation translocation into the plant [ 19 , 28 , 29 ]. Additionally, Zn induces indole acetic acid (IAA) biosynthesis, accelerating cell division and enlargement, and eliminating ROS [ 14 , 15 , 21 ].…”

“…Zinc (Zn) has numerous pivotal biochemical and molecular purposes in different plant species under normal or stressful conditions, including the upregulation of ROS scavenging strategies, the activation of several enzyme systems (about 300 enzymes), and improved nucleic acid biosynthesis [ 16 , 17 , 18 , 19 ]. Additionally, Zn is involved in indole acetic acid assimilation, cell development, and sexual reproduction [ 14 ].…”

Soil salinity is the main obstacle to worldwide sustainable productivity and food security. Zinc sulfate (Zn) and paclobutrazol (PBZ) as a cost-effective agent, has multiple biochemical functions in plant productivity. Meanwhile, their synergistic effects on inducing salt tolerance are indecisive and not often reported. A pot experiment was done for evaluating the defensive function of Zn (100 mg/L) or PBZ (200 mg/L) on salt (0, 50, 100 mM NaCl) affected pea plant growth, photosynthetic pigment, ions, antioxidant capacity, and yield. Salinity stress significantly reduces all growth and yield attributes of pea plants relative to nonsalinized treatment. This reduction was accompanied by a decline in chlorophyll, nitrogen, phosphorus, and potassium (K+), the ratio between K+ and sodium (Na+), as well as reduced glutathione (GSH) and glutathione reductase (GR). Alternatively, salinity increased Na+, carotenoid (CAR), proline (PRO), ascorbic acid (AsA), superoxide dismutase (SOD), catalase (CAT), and ascorbate peroxidase (APX) over nonsalinized treatment. Foliar spraying with Zn and PBZ under normal condition increased plant growth, nitrogen, phosphorus, potassium, K+/Na+ ratio, CAR, PRO, AsA, GSH, APX, GR, and yield and its quality, meanwhile decreased Na+ over nonsprayed plants. Application of Zn and PBZ counteracted the harmful effects of salinity on pea plants, by upregulating the antioxidant system, ion homeostasis, and improving chlorophyll biosynthesis that induced plant growth and yield components. In conclusion, Zn plus PBZ application at 30 and 45 days from sowing offset the injuries of salinity on pea plant growth and yield by upregulating the antioxidant capacity and increasing photosynthetic pigments.

“…Phosphorous fertiliser's efficacy is around 10-25 per cent worldwide and has a very low level of soil bio-availability, reaching a level of 1.0 mg / kg soil (Goldstein, 2000;Adnan et al, 2020). Zinc (Zn), a key element in all forms of life, including animals, human and plant organisms, is important and plays a key role (Alloway, 2004;Palai et al, 2020). Zn deficiency is an increasingly important risk factor in human health and global agriculture.…”

T HE MAXIMUM requirement of primary nutrients by hybrid maize crop deteriorate the fertility of soil, therefore farm yard manure (FYM) in combination with mineral zinc (Zn) and phosphorus (P) was selected for the increasing crop productivity, rehabilitate and sustain the precious soil. The research was carried out at the farm of the university of Agriculture Peshawar (UAP)during year 2019-20.To investigate the impact of mineral P from di-ammonium phosphate (DAP) and Zn from zinc sulphate (ZnSO 4 ) in combination with FYM on maize yield. The experiment was carried out in randomized completed block design (RCND) having eight different combinations of FYM, P and Zn were used excluding control. Spring hybrid variety of maize (CS-200) was used as a test crop. Basal dosage of nitrogen (N) 120 and potassium (K) 60 kg ha -1 were also applied. Physio-chemical properties of soil and concentration of Zn, P and K in maize leaves at silking stage and post harvested stage were measured. The objectives of this study was to determine the impact of FYM, P and (Zn) alone and in combination on yield of maize and soil properties and to gives best combination of organic fertilizers with mineral. From this research it was concluded that the combine application mineral P and Zn with FYM have linearly influenced the thousand grains weight, grain and biological yield of hybrid maize . The combine used of P and FYM @ of 90 kg ha -1 and 10 ton ha -1 shows influential impact on 1000 grains weight and grain yield, respectively. The soil organic matter and total N were significantly (P≤0.05) influenced by FYM applied alone, whereas the uptake of N, P and K by hybrid maize crop was found maximum in the plot where P in combination with FYM was added. Based on results the application of FYM @ 10 t ha -1 applied with 90 kg P ha -1 have the potential to improve maize yield as well as soil fertility and physical condition, also enhance the plant nutrient uptake and yield of hybrid maize, while the concentration of zinc in soil and plant were also greatly affected by the applied treatment. It shows antagonistic effect with P and its concentration become linearly decreased with the increase in P rates, while the maximum Zn concentration was showed by the sole application of zinc fertilizer.
