Background: Zn deficiency was predominant in soils of Chittoor district of Andhra Pradesh, which causes yield reduction in most of the crops especially in finger millet. Zinc has important role in enzyme activation viz., oxidoreductase, transferases, hydrolases, lyases, isomerases and ligases. The deficient soil gives us the zinc deficient food which is said to be the major root cause for malnutrition among the children. Hence present study was intended to find out most appropriate method and time of zinc fertilization for higher productivity, grain quality and zinc fortification with two major finger millet varieties viz., vakula and tirumala. Methods: The field experiment was laid out in split plot design with three replications and two varieties viz., vakula (V1) and tirumala (V2) with seven zinc application treatments which includes: control (T1); NPK (30-30-20) + FYM @ 10t ha-1 (T2); T2 + soil application (SA) of ZnSO4 @ 25 kg ha-1 as basal (T3); T2 + SA of chelated zinc sulphate @ 5 kg ha-1 as basal (T4); T2 + FA of 0.2% ZnSO4 at ear head emergence stage (T5); T2 + foliar application (FA) of 0.2% ZnSO4 at grain filling stage (T6); T2 + FA of 0.2% ZnSO4 at ear head emergence and grain filling stages (T7). Result: Foliar application of 0.2% ZnSO4 at ear head emergence and grain filling stages registered significantly highest grain and straw yield of 3150 kg ha-1 and 7364 kg ha-1, respectively compared to control and other zinc fertilization treatments. Between the two tested varieties tirumala variety recorded higher grain yield (2298 kg ha-1) compared to vakula variety (2230 kg ha-1).

Zinc (Zn) is a key mineral nutrient for plant and human growth and its deficiency can reduce the plant growth and development, however; agronomic bio-fortification can cure plant and human Zn deficiency. By using different Zn fertilization approaches, this study investigated the role and its impact on phenology, growth and yield of maize during two growing seasons 2015 and 2016. The treatments comprised of: no Zn application (ZnC0), basal application of 10 kg ZnSO4.7H2O ha-1 (ZnB1), basal application of 15 kg ZnSO4.7H2O ha-1 (ZnB2), foliar application of 1% solution of ZnSO4.7H2O ha-1 (ZnF3), foliar application of 1.5% solution of ZnSO4.7H2O ha-1 (ZnF4) applied to two hybrids of maize (YSM-112 and DK-6525). The maize hybrid DK-6525 showed superiority in term of growth and yield than YSM-112. The ZnF4 brings early emergence, tasseling and silking that resulted in early crop maturity. However, ZnB2 improved crop growth rate, grain yield and Zn concentration in maize grain by 44, 11.39 and 33.24%, respectively than ZnC0 (control). Regression model indicated that each 1 g increment in 1000-grain weight improved the grain yield by 0.01 and 0.16 t ha-1 of YSM-112 and DK-6525, respectively. Conclusively, it is concluded that DK-6525 with ZnB2 is suitable for optimal growth and yield of maize and would also be helpful to optimize the yield and Zn concentration of maize.

The Relationship

Abstract Cadmium (Cd) in agricultural soils can be taken up by wheat and transferred into the grains, risking human health. In this study, we tested the effects of nineteen foliar treatments alone, and also combined treatments on the Cd concentration of grains in pot/field experiments, and the field experiment, respectively. In addition, we tested the better growth period for foliar application to inhibit Cd accumulation in wheat grains. Foliar application of Ethylenediaminetetraacetic acid (EDTA), Sodium selenite (Se) and Sodium nitroprusside (SNP) can significantly reduce Cd concentration of wheat grains, with 49.2%, 29.6%, and 28.8% decreased respectively in the field. Foliar application of EDTA, Se, Zinc sulphate (Zn), Ascorbic acid (ASA), Sodium silicate (Si) and Ammonium molybdate (Mo) can significantly reduce Cd concentration of wheat grains in different treatments, with 32.3%, 32.0%, 27.7%, 27.7%, 26.3% and 25.9% decreased respectively in the pot. Thus, foliar application of 2 mM EDTA and 2 mM Se exerted excellent effects in controlling the Cd accumulation of wheat grains for both in pot and field experiment. We were concerned about the transfer of different aboveground tissues to the grain, foliar application with 0.1 mM Se or 2 mM EDTA significantly reduced Cd concentrations in grains both in grain filling stage and heading + grain-filling stage. Spraying at the filling stage of wheat has a better effect than at the heading stage for reducing the cadmium content in grains. In addition, the relationship between Cd concentration of grains and husks were significantly positive, while the relationship between Cd concentration of grains and flag leaves was significantly negative. Cd content in wheat grains decreased may be due to the Cd accumulation of flag leaves and the decrease of Cd transport from flag leaves and husks to the grains, which in turn reduces the transport of Cd to the grains.

The Impact

Crop productivity is limited by several environmental constraints. Among these, micronutrients availability to plants plays a key role in agricultural crops production. Boron is an important micronutrient for crops and it significantly aids in a grain setting. Soil applied boron become unavailable to plant due to fixation in soil sites and cause nutrients deficiency in plants, immature grain settings, and yield reduction. Thus, the aim of this work was to quantify the impact of the foliar application of boron gradients on the yield and growth of barley (Hordeum vulgare L.). Five treatments were studied, which included; T1= Control (0% B), T2 = 0.5% B, T3 = 1% B, T4 =1.5% B, and T5 =2% B. The results indicated that foliar application of B significantly increased the yield and growth traits in barley. However, 2% foliar application of B showed the highest value for all studied traits including; plant height (5.6%), number of tillers per plant (2.4%), spike length (32%), weight gain per spike (6.2%), seed index (6%), grain yield (10%), and biological yield (4%). Based on these findings, it can be concluded that the foliar application of B at 2% can be used to improve the growth and yield in barley.

A field experiment was conducted during kharif, 2016 and 2017 at S.V. Agricultural College farm, Tirupati to study the influence of spacing, nutrient and weed nutrient management practices on growth and yield of foxtail millet. Significant effects were noticed on growth and yield components viz., plant height, number of panicles m-2, weight of the panicle, grain weight panicle-1, grain and straw yield of foxtail millet. Among different plant geometries tried, closer spacing of 20 cm x10 cm registered taller plants, higher number of panicles m-2, higher grain and straw yield, where as the weight of the panicle, grain weight panicle-1 were found to be highest with 30 cm x10 cm. Among the micronutrient management practices, foliar application of ZnSO4@ 0.5% twice at the time of flowering and at grain filling stage along with 100% RDF registered taller plants as well as higher grain yields.Hand weeding at 20 DAS and 30 DAS outperformed other weed management practices. This was followed by pre-emergence application of butachlor @ 1 kg a.i ha-1 with one hand weeding at 30DAS.The study concluded that the closer spacing of 20cmx 10cm, foliar application of ZnSO4 at the time of flowering and 20 days after flowering along with RDF and hand weeding twice at 20 DAS and 30 DAS resulted in higher productivity of foxtail millet.

Rice Genotypes

Soil zinc (Zn) deficiency limits crop growth and yield besides its low concentration in grain and straw. Growing of Zn efficient cultivars with high crop yield at low Zn supply would represent a sustainable approach to crop production. Therefore, to evaluate Zn efficiency of rice genotypes, twenty eight different rice genotypes were evaluated under various treatments like three levels of Zn viz. low (without Zn), medium (10 kg Zn ha-1 soil) and high (20 kg Zn ha-1 soil + three foliar sprays of 0.5% Zn). Zinc efficiency index of all genotypes ranged from 65.5 to 102.6 % and Zn uptake efficiency ranged from 53.8 to 107 % with a mean value of 87.1 and 76.5 %. Cultivar GR-101 was having the highest Zn efficiency index as well as Zn efficiency compared to other genotype. Based on grain yield and Zn efficiency, the genotypes Ashoka-20, Narmad, GR-12, GR-3, GR-1 and GR-2 were classified as efficient and responsive, genotypes GR- 11, SLR -51214. GAUR-10 and GR-13 as efficient and non responsive, whereas, genotypes GR-101, GR-104, GR-102 and Lalkad as inefficient and responsive. The Gurjari, AAUDR-1, K-Kamod, GR-9, GR-5, P-2003 SK-20 and GR-7 genotype were classified as inefficient and non responsive. The efficient and responsive genotypes are most desirable as they would produce higher yield under low Zn concentration in soil and responded well under external application of Zn sources.

Zinc (Zn) deficiency in crops as well as in humans is still an important health issue, mainly in developing countries which is mostly due to poor dietary intake. This problem can be solved by the application of Zn to cereals known as bio fortification. Nanotechnology is one of the options to enhance the nutritional value of crops as some engineered nano-particles (NPs) could be used as a fertilizer. Zinc can be used in the form of zinc oxide (ZnO) NPs. The present study used the direct precipitation method to prepare ZnO NPs, characterized it by using dynamic light scattering (DLS), scanning electron microscopy (SEM) and fourier-transform infrared spectroscopy (FTIR) then evaluated the effect of Zinc nano-fertilizer on growth and yield of wheat (Triticum aestivum L.). The field experiment consists of seed treatment, foliar application and combination of seed treatment as well as foliar application of bulk Zn sources and Nano Zn source. Results showed that the seed treatment of ZnO NPs @1000 ppm followed by three foliar sprays of ZnO NPs @1000 ppm at 21, 45 and 90 days after sowing proved to be significantly superior in enhancing the plant height, number of effective tillers per plant, spike length, test weight, grain and straw yields, grain and straw zinc content and uptake by grain and straw.

Zinc (Zn) deficiency is a global micronutrient problem in agricultural systems. The main target of this experiment was to investigate the effectiveness of foliar application of Zn under field conditions. Grain yield and Zn concentration in seed were assessed with three replicate plots per treatment in a factorial (2 x 3 x 2) experiment for two barley cultivars (Yusuf and Julgeh), three foliar ZnO applications (nano, ordinary and nano+ordinary ZnO) and two commercial inocula of arbuscular mycorrhizal (AM) fungi (F. mosseae and R. irregularis). Among all Zn foliar applications, Zn applied in both nano and nano+ordinary forms were labile and resulted in the highest Zn concentration in grain of both barley cultivars. Cultivar Julgeh had higher grain Zn concentrations than did cultivar Yusuf in the same treatments. Nano ZnO was more effective than the ordinary form of ZnO and had the highest potential to improve physiological traits, plant growth and yield parameters in both cultivars. There was also a positive impact of the nano form of ZnO on phytase activity and carbonic anhydrase concentration in both barley cultivars. Inoculation with commercial inocula of AM fungi also enhanced grain Zn concentration, with Julgeh more responsive to inoculation with F. mosseae, and Yusuf more responsive to inoculation with R. irregularis. Generally, the combined application of Zn and inoculation with AM fungi improved physiological traits, grain yield and Zn availability to these two barley cultivars grown under field conditions. Accordingly, the nano form of Zn positively enhanced shoot morphological parameters, physiological parameters and grain Zn concentration. Application of the nano form ZnO in combination with inoculation with AM fungi had the most beneficial effects on grain Zn concentration, so this combined practice may have potential to reduce the requirement for application of synthetic Zn chemical fertilizers.

The aim of this work was to examine the ameliorative effect of foliar application of salicylic acid and potassium on antioxidant enzymes activity in wheat under saline conditions. Two wheat genotypes WL-711 (salt tolerant) and Kohistan-97 (salt sensitive) were used with salicylic acid (SA) and potassium (K+) foliar spray which were applied at both vegetative and grain filling stage under saline conditions. Various enzymatic antioxidant activities include catalase (CAT), peroxidase (POD), superoxide dismutase (SOD) and ascorbate peroxidase (APX) was assesed. Result cleared that foliar spray of salicylic acid and potassium decreased the damaged effect of salinity in both wheat genotypes especially Kohistan-97 which was more salt sensitive. Overall, foliarly applied salicylic acid and potassium reduces the adverse effects of reactive oxygen species and antioxidant enzymes on cellular metabolism that was disturbed by salt stress.
