“…Tomato is one of the main vegetables in world cuisine. It is essential in most foods and it also has much interest in the human body because it contains many nutrients (Abd Kadhum et al, 2019). Tomato is the most important vegetable crop and is considered the first rank in some countries whereas in others it will be the second in rank after potatoes (Gunawan, 2013).…”

This study was carried out from March to October 2021 at two different locations in Sulaimani governorate, the first location was the University of Sulaimani, College of Agricultural Engineering Sciences, and the second location located in Sulaimani, Sitak, Kani Naz, the study aimed to indicated the impact of gibberellic acid on seed germination of local tomato seeds, and evaluated the effect of foliar application of boric acid and alpha-Tocopherol (α-Tocopherol ) on the vegetative growth and yield of tomato plants. The seeds were soaked in gibberellic acid at different concentrations (0 ppm, 50 ppm, and 100 ppm), and foliar spraying of boric acid at various levels (0 ppm, 15 ppm, and 30 ppm) started two weeks after transplanting. Also, another foliar applied was α-Tocopherol at different levels (0 ppm, 125 ppm, and 250 ppm) when the plants start to flowering. The results showed that gibberellic acid had a significant effect on the tomato seed germination. Additionally, the result about the interaction between all factors revealed that the interaction among (S1*B2 *E3) had a height significant (p≤0.05) role on the vegetative growth, plant height (135.000 cm), number of branches. Plant -1 (57.000), the highest content of boron in leaves when using (S2*B3*E1) (0.460 mg. kg -1 ), and the highest yield. Plant -1 when using (S3*B2*E1) (3.187 kg). Whereas, all of the factors with all different concentrations had no significant (p˃0.05) effect on leaf area surface in tomato plants.

Measurements of serial production workpieces in the industry are performed by camera-controlled systems thanks to the advantage of speed. The measurement success of camera systems largely depends on the measurement algorithm. In this paper, an area-based diameter measurement algorithm that can be used in industrial machine vision applications is proposed. The success of the proposed method is demonstrated based on the sub-computation metric. In the proposed method, firstly, the noise on the obtained image is cleaned according to the connected component analysis. Then, the inner and outer diameters of the largest component are determined according to the area calculation. In the designed experimental setup, a back lighting illumination has been preferred. According to 3 different positioning types in the field of view of the camera, a total of 40 stamps of 4 types were measured 20 times with 3 different lenses. According to the test results, it has been observed that the position of the part on the field of view greatly affects the repeatability measurements. Also, sub-computation metric (C) is measured 2 in random positioning. This value increases up to 5 in the limited positioning that meets the industrial conditions. Tests have shown that the proposed method can measure the diameters of workpieces with precise tolerances in an industrial setting.
