“…This increase is caused by the same effective role previously mentioned of both zinc and iron deposited on the leaves by using a hollow cone nozzle. This result is in agreement with some previous studies (Anees et al, 2016;Liu et al, 2016;Saleem et al, 2016;Shivay et al, 2016;Alheidary, 2019). In the context of the interaction, the foliar spraying and nozzle type no significantly interaction between them in effecting on the leaf area.…”

: The field experiment was performed during the autumn growing season 2019 in Al Khyoot village of the Qurna town which is located at 75 km northern Basrah city centre. For improving the maize growth and yield, the effect of foliar spraying with iron and zinc and the most important technological characteristics of the knapsack sprayer such as nozzle types was studied. Three nozzle types were investigated as standard Flat fan nozzle, Hollow cone nozzle, and Tip nozzle (as reference nozzle in this study). Three foliar concentrations (0, Zn30 + Fe100 and Fe100+ Zn30) as well as a 16- litre capacity of the knapsack sprayer were used for fertilizer spraying experiments. All field experiments were carried out using the complete randomized block design (RCBD) with three replications. The results of the statistical analysis showed that there was a significant effect of the nozzle type and foliar spraying on the plant growth and yield characteristics as plant height, stem diameter, number of leaves, leaf area, number of grains, and yields (152.39 cm, 1.88 cm, 13.98, 4559 cm2, 376.51 and 5.51 Mg ha-1 respectively). Also, these characteristics showed an increase percentage as following (2.79%, 2.25%, 0.60%, 3.11%, 3.70%, and 1.73% respectively) when the hollow cone nozzle was used compared to the reference nozzle. In addition, an interaction between the studied factors also appeared a significant difference in the grain number and yield characteristics.

“…We used two coarse rice genotypes that took more Zn from the soil and it increased with an increase in P level. Moreover, we conducted the experiment in a remote area (Malakand) in a farmer's field where both P and Zn were deficient, and so the application of higher P levels improved leaf area index [33], dry matter partitioning into various plant parts [31], and increased yield and yield components (data not shown) thus resulted in higher Zn uptake by the rice plants. Increasing the accessibility of rice to phosphorus in the growth medium can bring Zn deficiency in plants by changing soil and plant factors, however, little is known about the exact mechanisms.…”

“…Few researchers [44][45][46] are of the view that soil application of Zn had a very little increasing effect on Zn concentrations of brown rice, while foliar Zn application caused greater increases. In the case of the maize crop, [33] reported improvement in growth and yield was observed due to foliar Zn applications especially under water stress conditions. According to [47], the combined application of foliar + soil is superior for both grain yield and grain Zn intake.…”

“…Zn availability for plant uptake from the soil is affected by the concentrations of other nutrients especially phosphorus [5], the properties of the soils [27,28], environmental conditions [29], and water availability [30,31]. Application of Zn is very important for crops because it activates different enzymes [32] that promote plant growth [4,30] and improves yield [17,33]. Increasing grain Zn concentration of rice represents an important challenge to be met by (1) breeding and (2) fertilizer application [34].…”

Continuous cropping of rice (Oryza sativa L.) and wheat (Triticum aestivum L.) deplete soil fertility and reduce crop productivity as well as zinc (Zn) concentrations in rice grains and straw. Low Zn concentrations in rice grains have a negative impact on human health, while low Zn concertation in rice straw creates a nutritional problem for animals. The current high yielding rice varieties and hybrids remove large quantities of Zn from the soils, lowering the residual concentrations of soil Zn for the subsequent crop (e.g., wheat). Field experiments were conducted on farmers field in Malakand with the objective to evaluate the impact of various combinations of phosphorus (0, 40, 80, and 120 kg ha−1) and Zn levels (0, 5, 10, and 15 kg ha−1) on biofortification of Zn in grains and straw of rice genotypes [fine (Bamati-385) vs. coarse (Fakhre-e-Malakand and Pukhraj)]. The results revealed that Zn biofortification in rice genotypes increased with the integrated use of both nutrients (P + Zn) when applied at higher rates (80 and 120 kg P ha−1, and 10 and 15 kg Zn ha−1, respectively). The biofortification of Zn in both grains and straw was higher in the coarse than fine rice genotypes (Pukhraj > Fakhre-e-Malakand > Basmati-385). It was concluded from this study that the application of higher P and Zn levels increased Zn contents in rice parts (grains and straw) under the rice-wheat system. We also concluded from this study that Zn concentrations in rice grains and straw are influenced by plant genetic factors and Zn management practices.

“…Their studies have shown that the linoleic acid present in the germ potentially inhibits aflatoxins B1 and G1. In another research article Amanullah et al studied the efficacy of foliar fertilizers such as foliar zinc and phosphorus in increasing the productivity of maize under stressed conditions [5]. Their studies have shown that these foliar fertilizers significantly improved the growth and productivity of maize under moisture stressed conditions.…”
