| Recent years have shown enthusiastic research interest to reduce pollution of non-target such as sensitive environmental areas, human and non-targeted crops. In this way, the most important issue is that intermittent spraying on the trees simply needs a detection system to apply the spray only to the target trees, allowing the sprayer to turn off between trees or in areas where trees are missing. So, in this study, we present a low-cost sensing system that can apply a variable amount of liquid according to detection of the tree canopy for plant protection products applications in orchards. Target detecting system was implemented on a 2000 liter conventional towed air-blast orchard sprayer. In this study, the target detecting system was designed on the... |

| The degree of ripeness is a key factor for consumption, marketing, and minimal processing of fruits. This study was conducted to describe the physicochemical changes (geometrical and gravimetrical properties) and the relationships between different ripeness indexes i.e. pH, total soluble solids (TSS), titratable acidity (TA), firmness, dry weight content (DW) and color of date fruit during four ripening periods on-tree including Kimri, Khalal, Rutab and Tamr stages. These four stages were selected by visual fruit color and days after anthesis (DAA). Duncan’s multiple tests was performed to separate means at a 5% level of significance. A correlation analysis by Pearson correlation matrix method was also made between the colorimetric ripeness parameters and... |
