Quality Monitoring of Saccharum officinarum (Sugarcane) Using Image Analysis

The yield of the sugarcane depends on the quality of the seed used for plantation. The traditional methods of cultivation of sugarcane by cutting random sections of a stalk called sets and sowing them for propagation purposes result in quality degradation. When a defective sugarcane part is used for propagation purposes poor quality sugarcanes are obtained. This results in wastage of a large number of resources used for cultivation purposes. In the paper, we propose an efficient method using image processing for determining the nodes of the sugarcane crop that are found suitable for the propagation of good quality sugarcane. We present the design of a hardware prototype that automatically cuts and gives the cultivator a suitable node that has to be sowed for fresh cultivation. We validate the proposed method by determining the quality of fifty samples of sugarcane stalks and observe that our method works with 93.62 percent efficiency.

Effect of variety, dates of planting and spraying with Growmore in some quantitative characteristics of dry cowpea horns: تأثير الصنف ومواعيد الزراعة والرش بالكرومور في بعض الصفات الكمية والنوعية لقرنات اللوبيا الجافة

The experiment was conducted in a special field in the area of Kanaan for the province of Diyala for the autumn agricultural season 2017 to study the effect of the date of cultivation and spraying paper in the form of the fertilizer of the vine in the growth and the yield of three varieties of cowpea. The study included three factors, the first three varieties of cowpea namely; Blackeye, Kafr Al- Sheikh and Ramshorn, and the second date of agriculture and included two dates; the first on 15/7/2017 and the second on 1/8/2017, The third factor is the spraying of the paper in the growmore fertilizer, which includes three levels: the first 50 mg l- 1 and the second 100 mg l- 1 and the third 150 mg l- 1 in addition to the comparison treatment (0 mg l- 1). Thus, the experiment contained twenty- four treatments, which are the combination of the above factors. The experiment was carried out in accordance with the system of splitting the splinters with the design of the complete random sections (RCBD) and with three replicates. The number of experimental units reached 72 units. The results were analyzed using the statistical program SAS, and the differences between the averages were measured using the TOKI test at a probability level of 0.05. The results were summarized as follows: Blackeye was superior in most traits, giving the highest values of 100 seed weight, seed weight, seed yield per plant, total seed yield, respectively, 34.12 g, 0.344 g, 242.10 g,- 1, 12.92 ha. While Kafr El- Sheikh was superior in the number of dry corns of cowpea, 66.21 pods, which exceeded the number of cultivated plants on the first date in all studied traits. This is a good indication that early agriculture in mid- July increases the yield and its components. As for the grow more product, the spray concentration was significantly higher than 100 mg/ L- 1 in the weight of 100 seeds, seed yield per plant, total seed yield, respectively 30.85 g, 289.89 g and 15.46 ha- 1, , While spraying the plants with the chromor product with both concentrations 100 and 150 mg L- 1 to their superiority significantly "in the characteristics of the number of corns and the rate of weight of a single seed.

Stereological Analysis of the Statistical Distribution of the Size of Graphite Nodules in DI

The estimate of a distribution law of the nodule diameters in a volume of cast iron provides information about the graphite nucleation kinetics, and also about the crystallization kinetics. This information is essential for building more accurate mathematical models of the alloy crystallization. The mapping of a Cumulative Distribution Function (CDF3) of radii for graphite nodules in ductile iron is presented on the base of a Probability Density Function (PDF1) of the chord length distribution for random sections of the sample at the planar cross-section.
