Sabrao Journal of Breeding and Genetics, 2024
Nanotechnology is a new and vital scientific transformation used in various fields globally. It has proven its recognition in agricultural sciences with environment-friendly fertilizers produced and applied, which are more efficient than traditional fertilizers. Nano-biotechnological techniques can benefit diverse processes related to plant biology, including seed germination, plant growth enhancement, plant nutrition improvement, secondary metabolites isolation, and protection provision against biotic and abiotic stress factors. Nanotechnology presents significant opportunities for agriculture due to its typical physicochemical traits, such as substantial surface area, heightened reactivity, adjustable pore size, and particle shape. These fertilizers have contributed to addressing the increasing challenges in crop production and food security and can meet the growing food demand of the world's population. Studies have shown that this technology can improve field establishment by increasing seed emergence, plant growth, and yield even under different stresses. Notably, nanotechnology exploration in Iraq, particularly in agriculture production, has focused only on research purposes. Therefore, the current review emphasizes the importance of nanoparticles in the context of plant systems.

During the spring season of 2021, a field trial was conducted at the experimental field of the College of Agricultural Engineering Sciences - University of Baghdad (located in Abu-Ghraib site). The objective was to investigate the impact of nano-zinc concentrations and their application dates on maize yield and its components. The experiment was designed as a split-plot experiment following a randomized complete block design with three replications. The main plot was assigned to spraying dates (at 50% tasseling (D1), 50% silking stage (D2), and completion of silking stage (D3). And Zinc concentrations (0, 100, 200, and 300 mg liter-1) were assigned to the sub-plots. The results of the statistical analysis revealed a significant impact of nano-zinc application timing on all studied traits. Notably, the earliest application date (D1) resulted in the highest average ear length (17.52 cm), number of ear rows (15.46 rows per ear), and number of grains per row (29.42 grains per row), seed ear weight (87.48 grams), and total grain yield of 6.65 tons per hectare. Moreover, nano-zinc concentrations demonstrated superiority across most yield component traits and grain yield, particularly at 300 mg L-1, This generated the highest average number of ear rows (17.82 rows per ear), grains per row (31.20 grains per row), ear grain weight (98.06 grams), and overall grain yield (7.49 tons per hectare). The study concludes that applying nano-zinc at the onset of the flowering stage is most effective, with the concentration of 300 mg L-1 standing out.

In the spring of 2023, researchers from the Agricultural Research Department of the Ministry of Agriculture in Abu Ghraib conducted a field experiment on their agricultural lands. Examining how different Sorghum cultivars’ growth properties were affected by hydrogen peroxide seed stimulation treatments and planting dates was the main objective of this research. A three-replica, three-factor Randomized Complete Block Design (RCBD) was used to arrange the experiment with split-plots. On 11/3/2023 and 25/3/2023, the primary plots were assigned for planting. Al-Khair, Buhooth - 70, and Rabih were the three white corn kinds that were planted in the secondary plots. In the tertiary experiments, a 9 ml l-1 concentration of hydrogen peroxide was used to stimulate the seeds. Two control groups, one priming the seedlings with just distilled water and the other with dried seeds, were also included. In terms of average growth qualities, the results demonstrated that sorghum seeds stimulated with distilled water produced the best outcomes. All growth attributes averaged out best on the 25/3/2023 planting date. Rabih cultivar outperformed the other varieties in traits of chlorophyll content, leaf area, and plant dry weight. The interaction of seeds stimulated with distilled water and planted on 25/3/2023 showed significant superiority in traits chlorophyll content, leaf area, and plant dry weight. Rabih seeds stimulated with distilled water give the highest averages for the all studied traits.

Two factorial experiments were conducted. One of them was laboratory experiment which was carried out at the Laboratory of Agricultural Engineering Sciences College, University of Baghdad during 2023. The other was conducted at the lath house with used the pots during spring season of 2023. The aim was to investigate the effect of seed priming duration with bio-stimulator (Appetizer) on germination characteristics and seedling emergence of Sorghum. The design of Lab. experiment was (CRD) while for the other experiment was (RCBD) with four replications. Each experiment consisted of two factors. The first factor included seeds priming treatments with bio-stimulator (Appetizer) concentrations (1, 2 and 3) ml l-1 and seeds soaking in distilled water, in addition to unsoaked seeds treatment (dry seed). The second factor was included seeds priming periods that is (8,16 and 24) h in room temperature. The results of Laboratory experiment showed that sorghum seeds primed with appetizer concentrations 3 ml l-1 gave highest averages of germination percentage in the first count, germination percentage in the final count, radical length, plumule length, seedling dry weight and seedling vigour index. While the comparision treatment (dry seed) gave the lowest averages for these characteristics and the priming period (24h) gave highest averages of germination percentage in the first count, germination percentage in the final count, radical length, plumule length, seedling dry weight and seedling vigour index. The results showed that iteration between the factors (seeds priming treatments with Appetizer and seed priming duration ) has significant effect in most characterstics. The results of pots experiment showed that sorghum seeds primed with appetizer concentrations 3 ml l-1 gave highest averages of emergence percentage in the first count and emergence percentage in the final count. The priming period (24h) gave highest averages of emergence percentage in the first count and emergence percentage in the final count.

During the spring season of 2021, a field experiment was conducted at the College of Agricultural Engineering Sciences - University of Baghdad (Abi Ghraib location). To investigate the impact of nano iron concentrations and their application dates on the yield and its components of maize. A factorial experiment was carried out in a split-plot arrangement. The main plots occupied the spraying dates (beginning of the male flowering stage, 50% female flowering and completion of female flowering) and symbolized in sequence. At the same time, the iron concentrations (0, 100, 200 and 300 mg. L-1) occupied sub-plots according to RCBD with three replicates. The results revealed that the dates of spraying nano iron substantially influenced most of the features tested. The early date (beginning of the male flowering stage) gave the highest average length of the ear (16.374 cm), the number of rows per ear (16.3 row ear-1), and the number of grains per ear (563.4 grain ear-1) and the total grain yield of 6.096 tons ha.-1. The results also showed that the concentrations of nano iron 300 mg L-1were superior in all the characteristics of the yield components and the grain yield, as it produced the most significant average for ear length, number of rows, number of grains per row, number of grains in the ear, weight of 500 grains, and total grain yield. It is concluded from this study that spraying at the beginning of the flowering stage is the most responsive to spraying the nano iron element, especially at the concentration of 300 mg L-1.
