This paper focuses on the study of different types of irrigation techniques based on fuzzy aggregation operators. Irrigation has been a vital characteristic of agriculture for over centuries and the result of the work of many cultures, and was the basis of the wealth and society. With the help of fuzzy aggregation operators, we introduce a new concept of multiple-attribute decision-making (MADM) problems, in which attribute values take the form of Pythagorean trapezoidal fuzzy information. In this paper, we propose some operational laws based on Pythagorean trapezoidal fuzzy (PTFNs) numbers and verified some basic properties. We also develop some aggregation operators to use the decision information represented by PTFNs, including the Pythagorean trapezoidal weighted geometric (PTFWG) operator, Pythagorean trapezoidal fuzzy ordered weighted geometric (PTFOWG) operator and Pythagorean trapezoidal fuzzy hybrid geometric (PTFHG) operator. At the end of this paper, we compare the result with existing methods to demonstrate the applicability and practicability of the developed decision-making method.
