It is very important to spray the chemicals (herbicides, pesticides, fungicides) very carefully and correctly using suitable tools to control weed and pests while keeping the environmental and health risks at very low level. To achieve this goal, it is necessary to study the effects of different factors on the behavior and movement patterns of sprayed particles from the beginning of the spraying to the end when the particles reach the plant. Therefore, for this purpose, in this study, the effect of three levels of pressure 2, 3 and 4 on the distribution of volumetric volume of fluid particles after exiting from Tee jet nozzles 110-02, 110-03, 110-04 and one newly designed nozzle has been investigated. This was performed by experimental and numerical methods using Computational Fluid Dynamic (CFD) method. The results revealed that the spraying pressure and nozzle type had significant effects on the particles volumetric distribution (p &lt; 0.01). All the treatments differed significantly. The innovative nozzle had the highest spraying performance at all the three pressures compared to the other nozzles.

This operation was conducted on 34 cumin accessions from six origins (local, India, Syria, Egypt, Turkey, and Saudi Arabia). To evaluate differences between the physical properties among accessions, length, width, thickness, and both the volumetric mass and the thousand-schizocarp mass were measured. Geometric properties (geometric mean diameter, sphericity index, specific mass and surface area) and gravitational parameters (bulk density, true density, and porosity) were calculated for each accession. Heritability (broad sense), phenotypic and genetic variabilities are also assessed. The average values of the evaluated parameters were found to be significantly different (p &lt; 0.01) between accessions. The physical characteristics of schizocarps were significantly influenced by their origin, cultivated provinces and irrigation methods. Length, width, thickness and length of style range on average from 5.7 to 6.8 mm, 1.5 to 2.5 mm, 1.2 to 1.8 mm and 0.6 to 0.9 mm, respectively. Local and Egyptian accessions were the best-sized accessions. Regarding the weight, the Indian accession C11 registered the best volumetric mass 52.9 g, while the thousand-mass was found to be higher in the local accession from Zagora C19 with 7.3 g. The results showed that the phenotypic coefficient of variation (PCV) was higher than the genotypic coefficient of variation (GCV). The highest PCV and GCV were length of style (30.0%) and true density (24.4%), respectively. Volumetric mass had the highest value of heritability (99%).
