A field experiment was conducted during the winter season 2018-2019 at Al- Qurna site to investigate the effect of row spacing and spraying of complete nano-fertilizer on growth and yield of Wheat (Triticum asetivum L.). The experiment was arranged in a split-plot by using R.C.B.D design with Three replicates, the main-plots were row Spacing (10, 20, and 30 cm), the sub-plots included Nano-fertilizer levels (0, 2.5, 3.5, and 4.5ml. L-1). Results showed that the row spacing gave higher value for most characters, the distance 30 cm rat gave plant height and flag leaf area, 1000 grain weight, grain yield, and bio yield, as they were (88.67cm, 46.02cm2,45.69g, 7.86 t. h-1, 21.37 t. h-1), respectively. Treatment of fertilization with nano spraying with a concentration of 4.5 ml. l-1 was significantly superior in most indicators of growth and yield, it gave the highest averages compared to other fertilizer levels in plant height, leaf area, weight of 1000 grains, grain yield, number of spikes, number of tillers reached (89.23 cm, 47.30 Cm2, 44.87 g, 7.96 t. ha-1, 650.22 spikes. m2, 750.56 tillers. m2) respectively. The interaction between factors was significant in most of the growth indicators in two components of yield (number of spikes and number of spike seeds) in addition to the biological yield.

Current study generated complexes of the novel heterocyclic ligand 3-(1-methyl-2-((1E,2E)-3-phenylallylidene) hydrazinyl)-5-phenyl-4H-1,2,4-triazole with Cr(lll), Co(ll), and Cu(II). Using techniques including 1H-NMR, mass spectrometry, FT-IR, and elemental analysis, scientists could determine key characteristics of the novel ligand. As spectra, Fourier transforms infrared (FTIR), magnetic susceptibility, atomic absorption, and conductance measurements were used to describe ligand complexes in contrast. Bacteria were used in an assay to test the antibacterial activity of each novel compound (Staphylococcus and Escherichia coli). Quantum chemical simulations performed using the DFT approach at the B3LYP/6-311++G level complemented the experimental data. Using Hyperchem 8.02 and the PM3 approach, this study hasdetermined the ligand's electrostatic potential and its complexes' geometries. The electrostatic potential that reveals useful data about the location's complexity.

The study was conducted during the Autumn season 2021 in one of the fields of the College of Agriculture - University of Basra, Karmat Ali site, in a silty clay soil by using a multi-purpose tillage machine. by split-blocks system according to a completely randomized design of a factorial experiment It included three factors: Three plowing depths (30, 40 and 50 cm), two rotary speeds of the rotary plow blades(250 and 300 rpm-1) give two levels of soil pulverizing, and three distances between the two opener furrows (35, 40 and 45 cm) give three different widths of furrows, And its effect on some yield attributes of sunflower, which included: weight of 1000 seeds, seed yield, percentage and oil yield. The results showed a significant increase in Weight of 1000 seeds, total seeds yield and oil yield, with an increase in the plowing depth from 30 to 50 cm, a low rotational speed of 250 rpm, and an increase in the distance between the boards of opener furrows from 35 to 45 cm.
