Enhancing Chickpea Yield and Nutrient Profile Through Phosphorous and Zinc Application

The field experiments conducted at the Student’s Instructional Farm, Chandra Shekhar Azad University of Agriculture and Technology, Kanpur, during the rabi season of 2021–22 aimed to investigate the impact of phosphorus and zinc on both yield and quality parameters of chickpea. Employing a factorial randomized block design with 16 treatment combinations and three replications, various combinations of phosphorus and zinc were tested, using the chickpea cultivar RVG-203 and following prescribed agricultural techniques. The most promising results were observed in treatment T15 [P90Zn6 ], which yielded the highest grain yield (18.65 q ha-1) and straw yield (21.86 q ha-1). Conversely, treatment T0 [P0 Zn0 ] exhibited the lowest grain yield (13.24 q ha-1) and straw yield (17.92 qha-1). Furthermore, nutrient content analysis showcased that treatment T15 [P90Zn6 ] boasted maximum values for grain nitrogen (N), phosphorus (P), potassium (K), and zinc (Zn) content at 3.35%, 0.65%, 0.65%, and 0.27 mg kg-1, respectively. In contrast, treatment T0 [P0 Zn0 ] displayed the minimum values in these parameters at 3.13%, 0.46%, 0.53%, and 0.20 mg kg-1, respectively. Similar trends were observed in the nutrient content of straw. Nutrient uptake analysis further emphasized the superiority of the treatment T15 [P90Zn6 ], recording maximum values for grain nitrogen (63.15 kg ha-1), phosphorus (12.25 kg ha-1), potassium (12.25 kg ha-1), and zinc (49.91 g ha-1), as well as in straw nitrogen (33.16 kg ha-1), phosphorus (7.47 kg ha-1), potassium (43.66 kg ha-1), and zinc (52.27 g ha-1). Conversely, treatment T0 [P0 Zn0 ] exhibited the lowest nutrient uptake for both grain and straw. In conclusion, the comprehensive analysis of treatment combinations demonstrated that the judicious application of phosphorus and zinc, as exemplified by treatment T15 [P90Zn6 ], significantly enhances chickpea yield and quality parameters, emphasizing the importance of balanced nutrient management for optimal agricultural productivity.

Evaluation of zinc application methods and integrated nutrient management on variation in growth, yield and yield contributing factors in wheat

Zinc is an important micro nutrient and plays an important role in improving the crop growth and productivity. Intensive agricultural practices due to rise in population have accelerated the use of chemical fertilizers which resulted in depletion of soil fertility. In this regard, a 2 year field experiment was conducted at Agricultural Research Farm of Lovely Professional University during rabi season in 2021-2022 and 2022-23 to examine the effect of different zinc application methods and integrated nutrient management on growth, yield and yield contributing factors on wheat. Three types of zinc application methods along with various levels of integrated nutrient management approaches were used for the study. The results revealed that a significant interaction between zinc application methods and integrated nutrient management practices was observed with dry matter accumulation (g/m2), Leaf area index, spikes/m2, spike length (cm), number of grains per spike and grain yield of wheat crop. Maximum improvement in grain yield (5.5 t/ha) was obtained when soil+foliar application of zinc was combined with 75% recommended dose of fertilizer + 2.5 t/ha farm yard manure + Zinc solubilizing bacteria. Additionally, these studies need to be repeated at many locations with various agro-climatic circumstances.

Enhancing maize yield and zinc uptake through foliar application of zinc sulfate in calcareous soil of Peshawar, Pakistan

Zinc deficiency in maize plants is a common problem, particularly in calcareous soils with pH above 7. This study aimed to investigate the impact of zinc sulfate (ZnSO4) applied in different forms (foliar and soil application) and concentrations on maize yield, zinc uptake, and nutrient use efficiency (NUE) in calcareous soil. The results demonstrated that zinc application significantly increased maize yield, zinc uptake, NUE, and the uptake of Nitrogen, Phosphorus, and Potassium. Foliar application of ZnSO4 was more effective than soil application in enhancing zinc uptake, with the highest uptake observed in plants treated with 1.5% ZnSO4 foliar spray. Additionally, zinc application increased zinc content in grains and surface soil, with the highest zinc content in grains found in plants treated with 1.5% ZnSO4 foliar spray and the highest zinc content in surface soil observed in plants treated with 10 kg ha-1 ZnSO4 soil application. These findings suggested that foliar application of ZnSO4 is an effective strategy for improving zinc uptake and grain zinc content in maize plants grown in calcareous soils.

The effect of zinc application on growth and alleviating shoot concentration of cadmium in durum wheat plant growth under conditions of salt and cadmium stress

A study was conducted in a greenhouse to investigate the effect of the combination of cadmium (Cd) and salinity (NaCl) stress in zinc (Zn) deficiency on growth, Cd accumulation in durum wheat (Triticum turgidum L. durum, cv. Balcali-2000), and micro (Zn, Fe, Cu, Mn) minerals differing in salt tolerance. The negative effects of Cd and NaCl stress on plant growth and Cd accumulation detected to alleviate Cd uptake on wheat growth increasing zinc application. The results revealed that Cd, NaCl and their combined stresses reduced shoots dry matter and Cd concentration in shoots increased compared to control pots. In increasing Cd and NaCl treatments, increasing Zn application significantly decreased the Cd concentration in shoot. In particularly, the decrease in Cd concentration was more noticeable with the improvement of Zn nutrition of plants at low doses of NaCl and Cd. The effect of increasing zinc treatments on reducing Cd accumulation decreased to slightly at high doses of Cd and NaCl. According to the results it can be suggested that Zn application to soils with low Cd content and medium salinity can be reduce Cd uptake by durum wheat.

The Potential Role of Zinc and Silicon in Improving Grain Yield and Lodging Resistance of Rice (Oryza sativa L.)

Understanding the agronomic interventions that ensure higher crop yields and minimize their chances of failure is critical for meeting global nutritional demands. Rice is a staple food crop that is prone to lodging risk, particularly when higher yields are desired. The potential role of a combined application of Zinc (Zn) and Silicon (Si) in determining the grain yield and lodging resistance has been rarely investigated under field conditions. Thus, field trials were carried out to evaluate the grain yield and lodging resistance of rice at two different locations i.e., Qionghai and Wuzhishan, under three levels of Zn (0, 40, and 80 kg ha−1) and Si (0, 120, and 240 kg ha−1). The results showed that Zn application at the rates of 40 and 80 kg ha−1 increased rice yield by 9% and 5% at Qionghai, and by 5% and 6% at Wuzhishan, respectively. The improved grain yield due to Zn application could be attributed to the increased panicles m−2, splikelets m−2, and aboveground biomass. Meanwhile, Zn failed to show any remarkable impact on stem and root lodging susceptibility. Conversely, no significant influence of applying Si on grain yield was observed, while its application at the rates of 120 and 240 kg Si ha−1 enhanced the stem and root lodging resistance (denoted by their respective safety factors, for stem (SFs) and for root (SFr) by 32% and 22% at Qionghai, and by 11% and 34% at Wuzhishan, respectively, compared to zero Si application. The improved lodging resistance in terms of SFs and SFr could be ascribed to the increased stem bending strength and anchorage strength, while self-weight moment of whole plant decreased. In summary, a beneficial role of Si in lodging resistance and Zn in yield enhancement were evidenced in the present study across the two sites. It can be concluded that by combining 40 kg Zn ha−1 with 120 kg Si ha−1, both grain yield and lodging resistance could be simultaneously improved in rice crops.

Exogenous Application of Potassium and Zinc for the Growth, Yield and Agronomic Zinc Biofortification of Wheat (Triticum aestivum L.)

In agriculture, the application of micronutrient application takes place through soil application, foliar spraying, or added seed treatments. Potassium (K) application fulfills the deficiency of K in soil due to a continuous exhaustive cropping system. Zinc (Zn) bio-fortification of seed by priming is responsible for increasing the concentration of Zn in the edible part of a seed with the aim of remedying malnutrition. For this, a field experiment was conducted at the Agronomic research area, Bahauddin Zakariya University, Multan. Treatment included different rates of K (0, 40, 60, and 80 kg ha-1) and different rates of Zn (0, 0.2, 0.4, and 0.6%). Potassium was applied in fertigation while zinc was applied in foliar form. The experiment was designed in Randomized complete block design (RCBD) and was repeated three times. It resulted that different rate of potassium and zinc application showed a significant effect on plant growth and yield attributes. Plant growth and yield increased with increasing the rate of potassium and zinc application and decreased with the decreasing the rate of application of potassium and zinc application. The maximum values for plant growth and yield attributes were observed with K3 and Zn3 while the minimum values were recorded with the application of K0 and Zn0. Results regarding the nutrient uptakes showed that maximum values for zinc uptake were also recorded in seed and stem attributes. Maximum values for zinc uptake in seed and stem (37.2 and 14.5 mg/kg) were observed in the Zn3 treatment and the minimum values for zinc uptake (30.1 and 11 mg/kg) were recorded Zn0 treatment, respectively. It was concluded that 80 kg ha-1 application of potassium with 0.6 % foliar application of zinc significantly affects the growth and yield of wheat crops. Zinc foliar application can be helpful for zinc fortification.

Response of Wheat to Farmyard Manure and Zinc Application in a Vertisol of Central India

Zinc (Zn) deficiency is one of the major global nutrition concerns, particularly in regions where diets are cereal dominant. About 50% of soils poor in zinc have resulted in zinc deficiency in cereal grains. Farmyard manure (FYM) with Zn application is the way to meet the Zn needs of crops and to raise the Zn content of grain that is ultimately consumed by people. Therefore, a pot experiment was conducted at the Department of Soil Science and Agricultural Chemistry of JNKVV, Jabalpur, in the Rabi season of 2020-2021 with three levels of FYM (0, 5.0, and 10 t ha-1) and three levels of zinc (0, 5 and 10 kg Zn ha-1) through ZnSO4.7H2O in a completely randomized design (CRD). Results revealed that the addition of 5 t FYM ha-1 + 10 kg Zn ha-1 produced significantly better results for the plant height compared to the control. The combined application of 10 t FYM ha-1 + 10 kg Zn ha-1 showed the highest SPAD (Soil Plant Analysis Development) meter reading at 21 DAS (Days after sowing), but it was the highest at the sole application of 10 t FYM ha-1 at 45 DAS. Significant enhancements in spike length (7.65 cm), weight and number of grains per spike (23.90), and DMP of 7.12 g pot-1 were recorded with the 5 kg Zn ha-1 sole application. However, the highest grain weight (2.50 g pot-1) was recorded with 5 t FYM ha-1 + 5 kg Zn ha-1, which was on par with 5 t FYM ha-1, 5 kg Zn ha-1, and 10 t FYM ha-1+10 kg Zn ha-1. The highest Zn content (48.95 mg kg-1) in wheat grain was recorded with 10 kg Zn ha-1, followed by 5 t FYM ha-1 + 10 kg Zn ha-1 (44.45 mg kg-1). The highest Zn uptake of 99.53 µg pot-1 by grain of wheat was recorded with 5 t FYM ha-1 + 5 kg Zn ha-1, which was significantly superior to all the treatments but on par with 5 kg Zn ha-1 (98.82 µg pot-1). Combined application of 5 t FYM ha-1 +10 kg Zn ha-1 maintain extractable zinc in soil as compared to control.

OPTIMIZING MUNGBEAN YIELD AND NUTRITIONAL QUALITY: THE SYNERGISTIC IMPACT OF ZINC-ENRICHED SOIL APPLICATION AND AMINO ACID FOLIAR BOOST

Zinc is crucial for chlorophyll production, and soil variables affect its availability for plants by regulating its sorption and desorption, thereby affecting its content. Amino acids are crucial proteins in plants for development, growth, and overall functioning, acting as stress-response molecules that initiate the production and accumulation of certain amino acids in response to environmental stresses. The study was designed in CRD-factorial to check the solo and combined application of amino acids (0 ppm, 250 ppm, and 500 ppm) and zinc (0 ppm, 10 ppm, and 15 ppm) on biochemical, growth, and yield attributes of mung bean. The results showed that total amino acids and phenolics were increased in dose (amino acids 250 + zinc 10) compared to control. In addition, crop growth rate (CGR) was increased in dose (amino acids 500 + zinc 10) over control. The 100-seed weight was also increased in dose (amino acids 250 + zinc 10) compared to control. The crop growth and yield rate decreased by increasing the amino acids and zinc doses. It is suggested to apply the dose (amino acids 250 + zinc 10) for better growth and yield production of mung bean.

Effect of Foliar Application of Phosphorus and Zinc on Biometric and Quality Attributes of Fodder Maize in Calcareous Saline-Sodic Soils

The hot climate is the major reason to promote salt salinization and sodication, which retards the crop productivity. The increase in salt-affected soils is adversely affecting worldwide productivity. The antagonistic effect among P and Zn causes nutrient deficiency and increases under saline conditions. The present study aimed to identify the targeted influence of foliar application of P and Zn on maize biometric and fodder quality parameters under saline-sodic conditions. The experiment was based on three P (0, 1, 2, 2.5%) and Zn levels (0, 1, and 1.5%), with three replications. The study showed that P concentration in maize was improved significantly with Z1P1 (51.0%) application, followed by Z0P2 (33.15%) and Z1.5P2.5 (28.0%). The Zn concentration enhanced with Z1P0 (91.73%), followed by Z0P1 (84.45%) and Z1.5P1 (84.18%). Nitrogen concentration improved with Z1.5P2.5 (39.84%). Total mineral contents were increased with Z1.5P2 (156.71%), followed by Z0P1 (142.64%) and Z0P2 (141.99%). Crude protein concentration was improved in Z1.5P1 (39.92%), followed by Z0P2 (11.92%). Crude fat percentage was increased with Z0P2.5 (51.89%), followed by Z0P1 (34.91%) as compared to Z0P0. The study concludes that foliar application of P and Zn in saline-sodic conditions helps retard the negative impacts of salts on biometric and quality parameters of maize fodder.

Cadmium (Cd) Minimization and Zinc (Zn) Biofortification in Wheat (Triticum aestivum L.) Grains by Spraying with the Foliar Zn Fertilizer in Cd-Contaminated Fields

The foliar application of zinc (Zn) has been regarded as a practical and economical way to reduce grain cadmium (Cd) accumulation and enhance grain quality in crops. Herein, a two-year field experiment was carried out to examine the efficacy of different application rates of the foliar Zn fertilizer in Cd reduction and microelement biofortification in wheat (Triticum aestivum L.) grains. The results show that the T4 and T5 treatments, 500 and 250-fold dilution of the foliar Zn fertilizer, respectively, increased the grain yield to varying degrees in the two years. When compared with controls and based on the average of the two years’ results, spraying with the foliar Zn fertilizer remarkably decreased grain Cd concentrations (44.5%), Cd translocation from stem to grain (TFStem/Grain) (4.92%), the HRI values of Cd (45.5%), PA/Ca (27.8%), PA/Fe (21.4%) and PA/Mn (5.81%) under the T2 treatment (1000-fold dilution). Furthermore, the T2 treatment significantly increased the Zn (37.8%), Ca (48.9%), Fe (37.6%), Mn (14.8%) and total protein (7.92%) contents and the estimated Zn bioavailability (28.9%) in wheat grains after two years. All these findings suggest that the foliar Zn fertilizer holds considerable promise as a safe crop production technique and a means of mitigating “hidden hunger” in developing countries.

Soil and foliar zinc application techniques influence the productivity, zinc concentration, and protein content in the grains of bread wheat varieties

Micronutrient zinc (Zn) is crucial for both humans and plants. To improve the micronutrient concentration in the grains of food crops, biofortification has already been established as one of the best approaches across the globe. The current study was carried out to assess Zn enrichment in a few common wheat varieties using different Zn delivery techniques. The following treatments were applied: T<sub>1</sub>: control (without Zn), T<sub>2</sub>: Soil application of 4 kg Zn ha-1 at final land preparation, T<sub>3</sub>: Foliar application of a 0.5% Zn solution (ZnSO<sub>4</sub> x7H<sub>2</sub>O) at both tillering and booting stages, and T<sub>4</sub>: soil application of 2 kg Zn ha-1 at final land preparation + foliar application of a 0.2% Zn solution (ZnSO<sub>4</sub> x7H<sub>2</sub>O) at both tillering and booting stages. All treatments were arranged in a split-plot design and repeated three times The findings of the study revealed that the various Zn application techniques had an impact on the Zn concentration in grains significantly, ranging from 23.9 to 32.2 µg g-1 across the varieties, with an average of 28.2 µg g-1 in the control. Among these various application techniques, the soil + foliar application induced the highest response of the Zn concentration in the grains ranging from 33.7 to 37.60 µg g-1. The average protein content (%) in the grains of all wheat varieties varied by 1.21, 1.47, and 1.51%, respectively, as a result of the use of the different Zn application methods. Considering the Zn-use efficiency (%), the most Zn-efficient wheat variety was BARI Gom 28, followed by BARI Gom 26, Binagom-1, BARI Gom 25, and BARI Gom 29. In the case of grain yield, wheat variety BARI Gom 26 (4.15 t ha-1) performed the best in the soil + foliar Zn application. The soil + foliar application method outperformed the other application techniques regarding the Zn concentration, yield, and protein content in the grain.

Wheat is a staple food in Pakistan and plays a vital role in the country's agriculture. It is one of the country's most widely cultivated and consumed crops, providing millions of people's food and livelihoods. The study reviewed the literature on the effect of foliar application of zinc on zinc-fortification and the yield of wheat grown under rainfed conditions. The review analyzed a range of studies that investigated the impact of the foliar application of zinc on wheat growth and grain quality. The results showed that foliar application of zinc significantly improves the zinc content of the wheat grain, which has important implications for addressing zinc deficiency in areas where it is prevalent. Additionally, the review revealed that zinc treatment leads to a noticeable increase in wheat yield, demonstrating its potential to improve agricultural productivity in rainfed farming systems. The review concludes by highlighting the need for further research to optimize the application rate and timing of foliar zinc application to maximize its benefits for wheat production under rainfed conditions. GRAPHICAL ABSTRACT

Synthesis of micro-structured zinc particles by thermal evaporation and their application in zinc containing coatings for steel corrosion protection

Micro-structured zinc particles with a variety of morphologies are synthesized by thermal evaporation technique. The zinc particles, which exhibit spherical (oblate), irregular-shaped polygonal and leave-like morphologies, are used to fabricate epoxy-based zinc-rich coatings for steel corrosion protection in heavy-duty environments. The assessment of their performance as sacrificial pigments highlights the significant influence of zinc particle morphology and size on coating properties. Accelerated salt spray test indicates that compared to commercial zinc dust, the synthesized irregular-shaped polygonal and leave-like zinc particles exhibit superior anticorrosion performance. EIS and OCP measurements indicate that enhanced barrier properties are obtained with the spherical (oblate) zinc particles due to their dense packing, while prolonged cathodic protection is achieved with the irregular-shaped polygonal and leave-like zinc particles due to the presence of highly electrochemically active zinc particles and the enhanced formation of protective simonkellite crystals on the coating surface.

Foliar zinc spraying improves assimilative capacity of sugar beet leaves by promoting magnesium and calcium uptake and enhancing photochemical performance

Sugar beet, a zinc-loving crop, is increasingly limited by zinc deficiency worldwide. Foliar zinc application is an effective and convenient way to supplement zinc fertilizer. However, the regulatory mechanism of foliar zinc spraying on sugar beet leaf photosynthetic characteristics remains unclear. Therefore, we investigated the effects of foliar ZnSO4·7H2O application (0, 0.1%, 0.2%, and 0.4%) on the photosynthetic performance of sugar beet leaves under controlled hydroponic conditions. The results indicated that a foliar spray of 0.2% Zn fertilizer was optimal for promoting sugar beet leaf growth. This concentration significantly reduced the leaf shape index of sugar beet, notably increasing leaf area, leaf mass ratio, and specific leaf weight. Foliar spraying of Zn (0.2%) substantially elevated the Zn content in sugar beet leaves, along with calcium (Ca) and magnesium (Mg) contents. Consequently, this led to an increase in the potential photochemical activity of PSII (Fv/Fo) (by 6.74%), net photosynthetic rate (Pn) (11.39%), apparent electron transport rate (ETR) (11.43%), actual photochemical efficiency of PSⅡ (Y (Ⅱ)) (11.46%), photochemical quenching coefficient (qP) (15.49%), and total chlorophyll content (25.17%). Ultimately, this increased sugar beet leaf dry matter weight (11.30%). In the cultivation and management of sugar beet, the application of 0.2% Zn fertilizer (2.88 mg plant−1) exhibited the potential to enhance Zn and Mg contents in sugar beet, improve photochemical properties, stimulate leaf growth, and boost light assimilation capacity. Our result suggested the foliar application of Zn might be a useful strategy for sugar beet crop management.

Field experiment was conducted to study the effect of organic manures, sulphur and foliar application of Zn and Bon seed yield and quality parameters of mustard crop. Eleven treatment combinations were tested in the field. The treatment with 100% NPKS+ Foliar spray of 0.5% Zinc-EDTA and 0.2% Boric acid at flower initiation and at 50% flowering resulted in highest seed yield and quality parameters of mustard under Northern Telangana zone.

Boosting linseed (Linum usitatissimum L.) production through application of micronutrients in North Western Himalaya

In acidic soils, for getting significantly higher yield of linseed with highest monitory returns, soil application of Zn SO4 @ 25 kg / ha+ foliar application of Zn SO4 @ 0.5 % at 45 DAS should be done. However, the other best options in this regard were soil application of zinc @ 25 kg Zn SO4/ ha + Borax @ 1.5 kg/ha and soil application of Zn SO4 @ 25 kg / ha followed by foliar application of Zn SO4 @ 0.5 % + Borax @ 0.3 % at 45 DAS.

Zinc and amino acids improve the growth, physiological, and biochemical attributes of corn under different irrigation levels

The global challenge of food security is threatened by drought stress. Exogenous application of zinc and amino acids could alleviate the negative impacts of water shortage on the growth, physiological, and biochemical attributes of plants. Based on this hypothesis, a field study was conducted to assess the effects of chelated zinc applied through irrigation systems and foliar amino acids on the growth, physiological and biochemical attributes of corn, under three irrigation levels at the recommended irrigation level (100%), and at 75% and 50% of the recommended rate. The treatments were arranged in randomized complete block design in triplicate. Treatment effects on yield varied with intensity and duration of water stress. An irrigation level of 100% means the normal supply of recommended water. In results, the implementation of irrigation levels on corn led to varying impacts on yield, depending on the intensity and duration of the water stress. Plants responded by reallocating nutrient accumulation within their tissues, which played a crucial role in mitigating the negative effects of water stress. The application of zinc and amino acids individually showed positive effects on corn improvement, as these promoted antioxidant defense systems and enhanced corn yield. However, the combined application of foliar amino acids and soil-applied zinc, particularly under the 75% irrigation level, had a tremendous effect on various examined parameters. There was an increase in catalase by 65.9%, superoxide dismutase by 17.1%, and peroxidase by 15.1%, resulting in improved corn yield by 114.6% and decreased hydrogen peroxide contents by 74.2% compared to control. In conclusion, adopting 75% of the applied water and treating corn plants with a combination of zinc and amino acids resulted in the highest yield, nutrient accumulation, antioxidant enzymes, chlorophyll contents, relative water contents, and carbohydrate levels.

The current study was conducted during Rabi 2018–19 at the All India Coordinated Research Project on Potato, which was located in the Department of Horticulture at Rajmata Vijyaraje Scindia Krishi Vishwa Vidyalya, Gwalior (M.P.). The purpose of the experiment was to determine how different foliar treatment concentrations of boron, zinc, and manganese affected the production characteristics and yield of the potato variety Kufri Chipsona-1 in Gwalior climate conditions. Eight foliar spray treatments of micronutrients were included in the experiment. Three replications of each of these treatments were arranged in a Randomized Block Design and statistical analysis was performed using analysis of variance methods. 'F' test was used to determine treatment significance. The application of zinc, manganese, and boron had a substantial impact on the yield characteristics and yield of potatoes, according to the treatment. In treatment T8 (Boron + Zinc + Manganese), the highest number of tubers (27.67/plant) and weights of tubers (680 g/plant) were noted. It is determined that using boron, zinc, and manganese would increase crop yields in potato farming under the climatic circumstances of Gwalior.
