“…For Zn, although this general consensus lacks, many studies may have suggested the application of zinc sulfate (ZnSO 4 -7H 2 O) as either a soil application before sowing (50 kg Zn ha −1 ) or a foliar application at the start of flowering (4-8 kg Zn ha −1 ), each one alone or in combination. There are other forms of Zn used, like ZnEDTA, which might be more efficient but its higher cost made it less accessible to farmers (Cakmak 2008;Das et al 2019).…”

Agronomic biofortification can be used to alleviate the deficient intake of selenium (Se) and zinc (Zn) by livestock. These two essential micronutrients for human and animals play an important role in many physiological functions and biological processes. The aim of the present study was to evaluate the suitability of forage peas, crop with an increasing importance as plant protein source, to be biofortified with a combined treatment of Zn (as ZnSO 4-7H 2 O) and Se (as Na 2 SeO 4). A 2-year field experiment was established in southern Spain under semiarid Mediterranean conditions, by following a split-split-plot design. The study year (2017/2018, 2018/2019) was considered the main-plot factor, soil Zn application (50 kg Zn ha −1 , nil Zn) as a subplot factor, and foliar application (nil, 10 g Se ha −1 , 8 kg Zn ha −1 , 10 g Se ha −1 + 8 kg Zn ha −1) as a sub-subplot factor. The combined application of 50-kg soil Zn ha −1 and the foliar application of 10 g Se ha −1 + 8 kg Zn ha −1 was the most effective treatment to increase the concentration in forage of Zn and Se, 4-fold and 5-fold, respectively, as well as the Zn bioavailability, forage yield (close to 30%), and crude protein (~8%). Thus, forage peas could be considered a very suitable crop to be included in biofortification programs under Mediterranean conditions with Zn and Se as target minerals.

“…Foliar applications of fertiliser in the grain maturation stage, near harvesting appears to be very efficient as starchy endosperm absorption is up to three-fold and the phytate concentration is at a sub-optimal level (Velu et al 2014). Das et al (2019) reported that an optimal time for increasing grain mineral concentration was achieved with a combination of foliar application of Zn after anthesis, plus a soil mineral application (Das et al 2019). Knez et al (2018) developed Zn biofortified wheat grain by a foliar application of 1.5 L ha −1 ZnSO 4 during the mid-vegetative growth stage followed by 2 L ha −1 ZnSO 4 two weeks after flowering.…”

Biofortification is a long-term strategy of delivering more iron (Fe) and zinc (Zn) to those most in need. Plant breeding programs within the CGIAR and NARS have made major advances in Fe- and Zn-dense variety development and there have been successful releases of new biofortified varieties. Recent research effort has led to a substantial improvement in our knowledge of Fe and Zn homeostasis and gene regulation, resulting in the identification of candidate genes for marker assisted selection. International cooperation between the agricultural and nutrition community has been strengthened, with numerous implementation and partnership strategies developed and employed over the years. The evidence on the effectiveness of Fe and Zn biofortified crops is slowly building up and the results are encouraging. Biofortification continues to be scaled out and further work is required to reach the general aim of eradicating the hidden hunger of Fe and Zn deficiency in the world’s population and ensuring nutritional security.

“…One of the ways to improve the technology of crop cultivation is to use chemicals to control biological processes with the help of plant growth regulators (Das et al, 2019;Moumita et al, 2019). e physiologically active substances of plant growth regulators are both the object and tool of the biotechnologies used in the selection of high-yielding crop cultivars.…”

Weed Control and Winter Wheat Crop Yield With the Application of Herbicides, Nitrogen Fertilizers, and Their Mixtures With Humic Growth Regulators

The aim of the present study was to determine the efficacy of the application of mixtures containing various combinations of humic substances, with herbicides and nitrogen fertilizers, in weed control and optimizing the plant nutrition system. We also aimed to evaluate the influence of these substances on winter wheat productivity. Five Ukrainian winter wheat cultivars (‘Kryzhynka,’ ‘Smuhlyanka,’ ‘Slavna,’ ‘Kubus,’ and ‘Mulan’) were sown in a randomized complete block design, with three replications, in the years 2014–2019. The analysis of the effect of the compositions containing herbicides, with various physiologically active substances, in a mixture with humic preparations (Humifield, 4R Foliar concentrate) was performed by counting weeds per square meter in each experimental plot. The best performance in weed control, including perennial species, was obtained from using a mixture of Grodil Maxi herbicide with the humic preparation, Humifield. The crop treatment of this mixture resulted in a 23.6% reduction in weeds, compared to the treatment with the Grodil Maxi herbicide only. At the same time, the complex application of a number of herbicides in a mixture with the humic preparation, 4R Foliar concentrate led to the opposite effect. Various applications of mixtures of humates (4R Foliar concentrate, 5R SoilBoost) with nitrogen fertilizers (ammonium nitrate; carbamide-ammonium mixture) to optimize the winter wheat nutritional system and yield increases have been studied. The highest yield increase of 20%–22% was harvested in the plots treated with 5R SoilBoost and 4R Foliar concentrate plus ammonium nitrate. In addition, the efficacy of wheat crop foliar feeding with mixtures of humates, plus a carbamide-ammonia mixture, in different phases of vegetation has been established. A yield increase of 10.0%–21.4% resulting from the use of such compositions was obtained.
