“…The carbohydrate content increased with increasing edaphic and foliar doses, showing that zinc increases the carbohydrate content in cowpea beans, and the 0.250 g edaphic-50.0 mM foliar dose produced the highest carbohydrate content. Many zinc-dependent enzymes are involved in carbohydrate metabolism, so zinc is involved in starch formation [47]. Protein contents between 25.27 and 29.58% were found, which were higher than the 23.90% protein reported for cowpea beans [36] and the control (0.0 g edaphic-0.0 mM foliar).…”

Zinc intake deficiency is a public health problem and increasing the nutrient’s content in the edible parts of plants can help mitigate it. The objective of this work was to determine the effect of the edaphic and foliar application of zinc sulphate on the nutrient content, bioactive compounds, and antioxidant capacity of cowpea beans (Vigna unguiculata L. Walpers). A sample of 100 grains was taken, and the length, width, thickness, weight, ash content, fat, humidity, fibers, carbohydrates, protein, energy, macro- and micro- nutrients, total phenols, flavonoids, anthocyanins, and antioxidant capacity were determined. The 0.250 g edaphic-12.5 mM foliar dose produced grains of a greater weight and size. All of the edaphic and foliar doses increased the grain zinc content, and the highest value was found with the 0.125 g edaphic-50.0 mM foliar dose. The total phenols increased with 12.5 g of edaphic zinc, while phenols, flavonoids, and the antioxidant capacity increased with 50.0 mM foliar zinc. The edaphic and foliar application of zinc sulphate increased the grain weight and size, zinc content, total phenols, and antioxidant capacity. Therefore, edaphic and foliar zinc biofortification enriches this nutrient in cowpea grains, and could reduce micronutrient malnutrition in the urban and rural communities of Mexico.

“…Zinc is required in the synthesis of tryptophan, which is a precursor of indole-3-acetic acid (Oosterhuis et al 1991), a hormone that inhibits abscission of squares and bolls. This nutrient also has a favourable eect on the photosynthetic activity of leaves and plant metabolism (Jyung et al 1975), which might account for higher accumulation of metabolites in reproductive organs (bolls). Results obtained are con®rmed by those of Zeng QingFang (1996).…”

Field experiments were conducted in two successive seasons at the Agricultural Research Centre, Giza, Egypt (on a clay loam soil), to determine the eects of N fertilization (added at rates of 107 and 161 kg N ha ±1 ) and foliar application of plant growth retardants (Pix, Cycocel and Alar; each applied once at 300 p.p.m., 75 days after planting) and zinc (applied at 0.0 and 50 p.p.m., two times, 80 and 95 days after planting) on cottonseed, protein and oil yields and oil properties of the Egyptian cotton cultivar Giza 75. The higher N rate, as well as the application of all growth retardants and zinc, resulted in an increase in cottonseed yield ha ±1 , seed index, seed protein content, oil and protein yields ha ±1 , seed oil refractive index, unsaponi®able matter and total unsaturated fatty acid content (oleic and linoleic). However, those treatments decreased the oil acid value, saponi®cation value, and total saturated fatty acid content. The seed oil content tended to decrease when the high N rate was applied, but tended to increase with the application of all growth retardants and zinc. There were some dierences between Pix, Cycocel and Alar regarding their eects on the studied characters. The highest increase in seed yield ha ±1 , seed index, and oil and protein yields ha ±1 was found with Pix, followed by Cycocel. The Cycocel treatment gave the lowest total saturated fatty acid oil content, followed by Alar.

“…This correlation reflects the energy value of barley for both malting and feeding. Reed (1940), Jyung et al (1975), and Sukhija et al (1987) reported the starch formation reduction under zinc deficiency in some crops. In this investigation, various amounts of starch content increase were obtained by zinc applications.…”

Field experiments were carried out to study effects of zinc application on quality traits of barley in 1994-1996. The treatments were applied as 0 and 23 kg/ha of zinc sulphate and incorporated into soil before sowing. The experimental design was split plot with four replications. Barley genotypes responded differently to zinc application in relation to thousand grains weight, protein content and starch content. A significant increase was determined for thousand grain weight in cultivars Tokak 157/37 and Cumhuriyet 50, for protein content in Orza, Bülbül 89 and Anadolu 86, for starch content in Karatay 94 and Cumhuriyet 50, while a significant decrease has been found for thousand grain weight in Karatay 94 and Obruk 86 and for protein content in Karatay 94, Cumhuriyet 50 and Tarm 92. When feeding and malting quality are considered together, Karatay 94 and Cumhuriyet 50 are the most suitable cultivars for growing in zinc-applied soils of semi arid areas.
