The dairy industry has been undergoing changes for years, introducing innovations and pushing the boundaries of the category and consumer experience. Numerous factors, such as economic, psychological, cultural, socio-demographic, personal and many others, influence the decision to buy and consume a certain dairy product. It is important to qualitatively research and identify factors that significantly influence consumer behavior. Consumers also set certain criteria when it comes to brand, taste, nutritional value, marketing, product origin, on the basis of which we conclude that knowing consumer preferences also means success in the market. Due to the previously stated reasons, the main goal of this paper is to determine consumer purchasing behavior towards dairy products and their preferences.The survey method was used in the research to collect primary data, and a survey questionnaire was used as a research instrument. A total of 250 respondents participated in this research, which is conducted in Bosnia and Herzegovina.

A two-year experiment was conducted with a local maize hybrid under full (F) and deficit (D) drip irrigation and rainfed conditions (R) to estimate maize evapotranspiration in Bosnia and Herzegovina (BiH). Three approaches, namely, A&P, SIMDualKc (SD), and vegetation index (VI), to estimate the actual crop coefficient (Kc act), the actual basal crop coefficient (Kcb act), and the actual crop evapotranspiration (ETc act), were applied with the dual crop coefficient method and remote sensing (RS) data for the first time. While Kcb act from all approaches matched FAO56 tabulated values, SD showed differences in comparison to A&P of up to 0.24 in D and R conditions, especially in the initial and mid-season stages. VI demonstrated very good performance in all treatments. In F, the obtained Kc act for all approaches during the initial and end stages were higher than the tabulated values, ranging from 0.71 to 0.87 for the Kc ini act and from 0.80 to 1.06 for the Kc end act, while the mid-season period showed very good agreement with the literature. The maize crop evapotranspiration range is 769–813 mm, 480–752 mm, and 332–618 mm for F, D, and R, respectively. The results confirmed the suitability of both approaches (SD and VI) to estimate maize crop evapotranspiration under F, with the VI approach demonstrating an advantage in calculating Kcb act, Kc act, and ETc act values under water stress conditions. The higher observed yields (67.6%) under irrigation conditions emphasize the need to transition from rainfed to irrigation-dependent agriculture in BiH, even for drought-resistant crops like maize.
