Prioritization of Methods and Criteria of Spraying for Wheat Fields by Analytical Hierarchy Process (AHP)

In the process of crop production, selecting the appropriate spraying method is very important. On the other hand, selecting the most appropriate criterion for evaluating and selecting pesticides is essential. In the first stage of this research, according to the important criteria of evaluation of spraying operations; the sprayers of Knapsack micronair, Tractor boom, Tractor lance, Knapsack atomizer and Turboliner were compared for sparying wheat fields in Alborz, West azarbaijan, Khoozestan and Razavi khorasan proviences with a completely randomized design. In the second step, the results of the first experiment were analyzed using AHP method. According to the results, the scoring methods were evaluated based on the criteria of spraying, spraying volume, drift, field capacity, spray uniformity, crop blunder, spraying nominal power, effectiveness and cost, after normalizing and analyzing the data, weight of Knapsack micronir, Tractor boom, Turboliner, Knapsack atomizer, and Tractor Lance sprayers were 0.337, 0.223, 0.175, 0.0 170 and 0.078, respectively. The Knapsack micronair and Tractor lance sprayers was the best and worst sprayer according to the weights obtained. The inconsistency coefficient of weights was 0.08. The highest and lowest criterion weight was 0.253 and 0.038 respectively and related to the effectiveness of controlling weeds and pests and crop blunder. In this situation, the inconsistency coefficient was 0.09.
