Computer aided decision making to use optimum water in safflower growing

Abstract

n plants, it is one of the important factors to provide ecological factors for productivity. Plants perceive the effects of environmental factorsoutside as stress and create appropriate physiological responses in their metabolism. Water stress is a type of abiotic stress and is oneof the important factors affecting the growth and development of plants. Irrigation water management is very important for sustainableuse of water resources. Therefore, support tools are becoming increasingly important in deciding irrigation. With the developments thetechnology, computerized support applications are usually used in agricultural areas. In the study, it is aimed to determine the effects ofirrigation applications performed in different periods on yield quality and spectral reflections of safflower plant and to create applicableirrigation programs in safflower cultivation. From the reflections detained from safflower leaves by using spectroradiometer device, thedetermination of safflower plant according to water ratio different situations is done. Reflections are taken as three groups where theplants are grown at wavelengths of 325 nm to 1075 nm. Water due diligence related with safflower is consist of two stages. The firststage is the provision of the feature vector, the second stage is the classification of the feature vector related to data. As classificationmethods, support vector machine, k-nearest neighbor and decision tree are used. In comparison of three groups, the average value ofthe performance is high. As a result, considering the fallowed method and the procedure used, it is evaluated that such studies can beused in agriculture and cultivation.
