In this study, application of different bacterial strains obtained from different ecosystems of Turkey with increasing doses of chemical fertilizers (NPK) was repeated for two years in field conditions in order to determine the effects on plant growth, yield and quality in cauliflower. Six PGPR strains (SA7, SB39, YÖ19, YÖ15, YÖ,41, SK72 107cfu/ml) from the trial subjects and a control group were added. Fertilizer applications were determined over the recommended dose; The rates of 0% NPK0, 50% NPK, 100% NPK and 200% NPK were applied. In the study, crown length, crown diameter, crown weight, leaf length, leaf diameter and marketable yield values were measured in sample plants selected on the basis of plots. Marketable yield values for 2021; NPK0 dose YÖ41, YÖ15 (2.55 ton ha -1 ), 1/4NPK dose YÖ41 (2.98 ton ha -1 ), 1/2NPK dose YÖ41, YÖ15 (4.57 ton ha -1 ), NPK dose YÖ41 (4.74 ton ha -1 ), 2NPK dose It was determined as YÖ41 (4.69 ton ha -1 ). Marketable yield values for 2022; NPK0 dose YÖ41 (2.16 ton ha -1 ), 1/4NPK dose SA7 (3.26 ton ha -1 ), 1/2NPK dose YÖ41 (4.73 ton ha -1 ), NPK dose YÖ41 (5.03 ton ha -1 ), 2NPK dose YÖ41 (5.11 ton ha -1 ) was determined. As a result of the research, it was determined that the effects of bacterial applications on the growth of the cauliflower plant are important. When the effects of applied bacterial strains on plant growth were examined, YÖ41, YÖ15 bacterial strains came to the fore, while other bacterial strains had a positive effect on all parameters.

“…It was demonstrated that Azospirillum and Azotobacter bacteria produce adequate amounts of cytokinins and Auxins (IAA) which accelerates plant growth by increasing the uptake of nutrients from the soil and increasing length of branches and roots [35,36]. A combination of Azotobacter chroococcum with Pseudomonas fluorescens was reported to improve broccoli growth [37]. Sarhan reported a positive effect of Azotobacter on growth and yield of potato plants [38].…”

The present study was carried out at Baqubah Nursery, Directorate of Agriculture, Diyala Province, Iraq, during the period of March to October 2017, to investigate the effects of magnetized water with bio and chemical fertilizers on the butternut squash. A factorial experiment with three replications was conducted and two factors were investigated; the state of water (magnetized water and non-magnetized water) and the fertilizer type (chemical fertilizer: urea 100 kg N/ hectare; bio-fertilizers: Azotobacterchroococcum and Azospirillumbrasilense + chemical fertilizer in 1:1 ratio). The results revealed that the magnetized water with bio + chemical fertilizers recorded the highest rate of fruit weight that reached 786.0 ,807.3 and 775.3 g at the first, second and third harvests, respectively. The effect of the magnetized water was significant on the rate of fruit yield/plant which reached 3745.0 g at the first harvest, while bio + chemical fertilizer recorded the highest rate that reached 2419.8 and 1404.3 g at the second and the third harvests, respectively. Magnetized water with bio + chemical fertilizers showed significant increments in total yield / plant (7822.3 g) and total yield / hectare (31289.3 kg). The treatment with magnetized water and bio and chemical fertilizer were significant in fruit content of total soluble solid (TSS %) after 185 days, which reached 13.0 % and 12.2 %, respectively, while bio + chemical fertilizer was superior in the yield of fructose sugar and fibers which reached 10.4 and 12.7 % , respectively.

Potential Mutation in PDS Gene That Causes Herbicide Resistance in Wild Radish Grows With Wheat Crop

A field experiment set out during the winter of 2022–2023 availed one of the Holy Kerbala Governorate's agricultural experimental fields. The study aimed to evaluate the efficacy of some herbicides in controlling the wild radish weeds accompanying the wheat crop, as well as, diagnosing genetic mutations in the PDS gene responsible for resistance to herbicides in wild radish. The experiment employed a randomized complete block design (RCBD) with a split-plot arrangement and three replications. The main plots included five groups of wild radish seeds taken from five Iraqi Governorates, i.e., Najaf, Kerbala, Babel, Diwaniyah, and Wasit. The subplots contained four herbicides: Navigator, Tatsteler, Mark zone, and Decimate, in addition to the treatment of spraying with water only. Wild radish seeds serve for artificially infecting wheat seeds after field preparation. The study also measured wheat yield components, with the weeds appraised twice after 60 and 90 days of management. Genomic alterations in the PDS gene caused herbicide resistance in wild radish. The global herbicide-resistant cultivar has two missense mutations in codons 69 and 330 (TGT → TAT and CGT → GGT), encoding for Cys → Tyr and Arg → Gly. These alterations were identical in all weeds studied, but some Governorates had new mutations, such as, in the seeds of the Babylon Governorate's weed. The evaluation of the efficiency of chemical pesticides comes after 60 and 90 days. Wild radish seeds in the targeted Governorates differed in all features. The herbicides Navigator and Decimate are vital in giving the best percentages of control and inhibition in wild radish weeds. Chemical herbicides have enhanced wheat production by eradicating weeds, specifically difficult ones. Genetic changes in wild radish weeds in wheat crops make some chemical herbicides less effective. Herbicide-resistant radish weed seeds are genetically mutated. Thus, herbicides can target gene variants and be diversified to prevent weed resistance.
