Production of many cut flowers, such as lilium, is very common in Iran. Flower quality has special importance in lilium flower production process, and proper nutrition is one of the major effective factors. This research was conducted to investigate the effect of different concentrations of potassium silicate, nano-silicon and calcium chloride on concentration of potassium, calcium and magnesiu...
The nutritional problems in almond orchards have increased because of alkaline soils and insufficient nutrition. This study was done to evaluate the effect of nano-chelate super plus ZFM (Zinc, Iron and Manganese) spraying on quantitative and qualitative characteristics of almond commercial cultivars. This work was carried out in factorial experiment base on randomized complete block design wit...
ABSTRACT- A real-time, site-specific, machine-vision based, inter-row patch herbicide application system was developed and evaluated. The image resolution was 640 × 480 pixels covering a total area of 350 mm x 240 mm of a field composed of four quadrants of 350 mm x 60 mm each. The image frames were processed by LabView® and MatLab®. The developed algorithm, based on weed coverage ratio and seg...
Variable rate technology-spraying technologies are new aspect of sustainable agriculture. In these technologies, the chemical is applied in the needed level of farm where there is a high intensity of pests and weeds. The purpose of this paper was to study the agricultural specialists' attitude toward and intention to use variable rate technology-spraying technologies in Jihad-e-Keshavarzi organ...
in this research, the effect of foliar spraying times and different levels of farmax® nano fertilizer on morphological characteristic and dry and fresh flower yield, essential oil and chamazulene percentage of chamomile (matricaria recutita l.) cv. bodegold was studied. the experiment was factorial in the bacic of randomized complete blocked design (rcbd) with eight treatment and four replicati...
The Spray Treatment Planner is an intelligent decision support system for productivity and efficiency evaluation in an aerial spray treatment project. It can be used as a tool to plan the schedule for spraying pesticides aerially. STP schedules the spraying operation of selected blocks from selected airports using single or multiple aircraft(s). The scheduling is done to maximize the spray effi...
Electro spraying is a method of liquid atomisation by electrical forces. Recently, the electrospraying entered in microfluidic devices and nanotechnology. Spraying solutions or suspensions allows production of fine particles, down to nanometer size, which can be used in industrial processes or for research purposes. It is a process when electrostatic forces are the only energy source leading to...
Detonation-produced hydroxyapatite coatings were studied by scanning electron microscopy (SEM), X-ray powder diffraction (XRD), Raman spectroscopy, and electron paramagnetic resonance (EPR) spectroscopy. The source material for detonation spraying was a B-type carbonated hydroxyapatite powder. The coatings consisted of tetracalcium phosphate and apatite. The ratio depended slightly on the degre...
Newman estimated that 42 per cent of the decline in mortality in Sri Lanka between 1930-1945 and 1946-1960 was attributable to DDT-spraying; Molineaux estimated 27 per cent; Gray judged that 23 per cent of the decline between 1936-1945 and 1946-1960 was due to DDT. Here the Newman-Gray-Molineaux approach is criticized, the main point being that they ignored a significant improvement in mortalit...
