The Spraying Technology on Iraqi Agricultural Researches
Many of the Iraqi agricultural researches are used spraying technique to add chemical products including pesticides and growth regulators. Various studies were performed to study the effect of these substances at different concentrations to improve plant production. In order to adopt specific criteria of spraying researches and to replicate them easily, it is a necessary to mention all information related to the spraying processes and regulations for improving sprayer’s performance by increasing the amount of pesticide deposited on the target. The current study aims to survey Iraqi researches in details and analyse them randomly. Also, to highlight on the importance of information applied in spraying techniques and its relationship with improving of agricultural production. The survey showed most of these researches does not mention sufficiently the basic information, especially in the spraying or calibrating processes. These processes are important to ensure the best distribution of spraying in the field depending on type of sprayer, nozzle type, and operating pressure. Also, some of these researches do not show the application rate of pesticide and the factors affected on it, which may lead to imbalance in homogenization of the pesticide distribution. This study recommended using a power sprayer to avoid the misapplication in droplets distribution in comparison with pack back sprayers, which have a complication in the operating pressure and nozzle height regulation. Another recommendation was a necessity to select the perfect nozzle type that agrees with the global publications.
