“…1). In good agreement with these results, Nawaz et al (2015), in a field study by using five commonly-cultivated wheat cultivars in Pakistan (i.e., Bakhar-2002, Shafaq-2006, Sehar-2006, Faisalabad-2008, and Lasani-2008, showed that Lasani-2008 was the most responsive cultivar to Zn fertilization in terms of yield enhancement on a similar alkaline-calcareous soil having 0.36 mg kg -1 DTPA-extractable Zn.…”

Seeds enriched with zinc (Zn) are ususally associated with better germination, more vigorous seedlings and higher yields. However, agronomic benefits of high‐Zn seeds were not studied under diverse agro‐climatic field conditions. This study investigated effects of low‐Zn and high‐Zn seeds (biofortified by foliar Zn fertilization of maternal plants under field conditions) of wheat (Tritcum aestivum L.), rice (Oryza sativa L.), and common bean (Phaseolus vulgaris L.) on seedling density, grain yield and grain Zn concentration in 31 field locations over two years in six countries. Experimental treatments were: (1) low‐Zn seeds and no soil Zn fertilization (control treatment), (2) low‐Zn seeds + soil Zn fertilization, and (3) Zn‐biofortified seeds and no soil Zn fertilization. The wheat experiments were established in China, India, Pakistan, and Zambia, the rice experiments in China, India and Thailand, and the common bean experiment in Brazil. When compared to the control treatment, soil Zn fertilization increased wheat grain yield in all six locations in India, two locations in Pakistan and one location in China. Zinc‐biofortified seeds also increased wheat grain yield in all four locations in Pakistan and four locations in India compared to the control treatment. Across all countries over 2 years, Zn‐biofortified wheat seeds increased plant population by 26.8% and grain yield by 5.37%. In rice, soil Zn fertilization increased paddy yield in all four locations in India and one location in Thailand. Across all countries, paddy yield increase was 8.2% by soil Zn fertilization and 5.3% by Zn‐biofortified seeds when compared to the control treatment. In common bean, soil Zn application as well as Zn‐biofortified seed increased grain yield in one location in Brazil. Effects of soil Zn fertilization and high‐Zn seed on grain Zn density were generally low. This study, at 31 field locations in six countries over two years, revealed that the seeds biofortfied with Zn enhanced crop productivity at many locations with different soil and environmental conditions. As high‐Zn grains are a by‐product of Zn biofortification, use of Zn‐enriched grains as seed in the next cropping season can contribute to enhance crop productivity in a cost‐effective manner.

“…The stimulating effect of both HA and Zn is partly associated with the higher uptake of mineral nutrients (33). Similarly, positive effects of HA and Zn application on the yield of different crops such as pearl millet (34), wheat (30,31,35,36) and sunflower (37) have been reported in other studies. In some studies, it has been shown that 5 or 10 kg Zn ha -1 ( 25-50 kg ZnSO ⁓ 4.7H2O) application is sufficient for high yield of cereals (38,39).…”

The objectives of the study were to determine the effects of humic acid (HA) and zinc (Zn) applications on winter tolerance and yield performance of oat (cv. Albatros) planted in winter and spring sowing times (ST). We conducted the study in the 2017/2018 growing season. The experimental layout was split-split plots with three replications. Sowing times (winter and spring) comprised of the main plots. Humic acid application (with HA and without HA) was in the sub-plots, and Zn application rates (0, 23 and 46 kg ha-1) were in the sub-sub-plots. Chlorophyll content of plants was measured at the heading stage, while plant height, panicle height, panicle weight, number of grain per panicle, weight of grains per panicle, harvest index and grain yield were determined at the harvest. The effects of HA and Zn applications in both ST increased the chlorophyll content, yield and yield components. The results showed that cold tolerance of oat plants can be increased by the application of HA and 46 kg ZnSO4.7H2O ha -1. Overall performance of winter season was better than spring; thus, oat can be cultivated in winter under warm winter climate conditions. In addition, the HA and Zn applications can be used for other cold sensitive plant species to increase the cold tolerance which is a prevalent environmental stress affecting productivity of crops.

“…The yield penalty due to Zn deficiency has been reported in several crops in Asian countries like India, Pakistan, and China, and Australia . In India, several studies suggested that Zn fertilization increases productivity and profitability of rice and other cereals . Among rice parts, Zn concentration decreased in the order bran > straw > husk > grain, indicating that brown rice are much denser in Zn than polished rice grain.…”

Intensive cultivation and introduction of input‐responsive high‐yielding varieties with application of major nutrients in rice–wheat rotation of Indo‐Gangetic plains (IGPs) lead to multiple nutrient deficiencies. A survey of Indian soils has shown that 40% are deficient in available zinc (Zn), 33% in sulfur (S), and 33% in boron (B). Studies have indicated that application of these nutrients with major nutrients can improve the crop productivity. Keeping the importance of aromatic rice in view, coated‐urea materials and their effects on rice yields, nitrogen (N), and Zn content in different parts and input economics are evaluated. Three field trials are conducted on aromatic rice to test boron‐coated urea (BCU), sulfur‐coated urea (SCU), and zinc‐coated urea (ZnCU) in 2013 and 2014. Results indicate that the highest yields are obtained with 0.5% BCU, 5.0% SCU, and 2.5% ZnCU as zinc sulfate heptahydrate. These treatments increase grain yield by 13%, 25%, and 17.9% over prilled urea (PU). Moreover, 0.5% BCU, 5% SCU, and 2.5% ZnCU register the highest N, S, and Zn contents in bran, husk, grain, and straw. Coated‐urea materials also improve use efficiencies and harvest index of N and Zn over PU. The findings of this study suggest that 0.5% boron, 5.0% sulfur, or 2.5% zinc‐coated urea show improvement in returns and benefit–cost ratio in aromatic rice of western IGPs.
