The main objective of the research was to determine the factors associated with the purchasing decision of consumers of an agribusiness company. In recent years, companies in the agricultural sector have faced constant challenges, especially situations of economic slowdown and social problems. For this reason, marketing specialists have the great challenge of investigating the complex and uncertain behavior of consumers in various scenarios when deciding to purchase a product and/or service, taking into consideration the needs of human beings, depending on the lifestyle, habits and beliefs of society. Applied quantitative research was carried out. A non-experimental, crosssectional, multivariate correlational research design was used. Likewise, for the operationalization of the variable (factors), a survey was used with the following indicators: income, price, offers, family, status, reference groups, life cycle, sex, occupation, motivation and perception; considering three scales for the measurement: ratio, nominal and ordinal. For the operationalization of the variable (purchase decision), a survey was used with the following indicators: need inquiry, complexity of brand search, brand evaluation before purchase, post-purchase analysis, attitude and habitual purchases; considering the nominal scale for the measurement. The sample consisted of 143 clients of an agribusiness company, and the simple random probabilistic method was used for sampling. A questionnaire was used to collect the information and the instrument was validated by expert judgment; in addition, a pilot test was carried out with Cronbach's Alpha on the purchase decision variable with a result of 0.876, which allowed demonstrating the reliability of the instrument. For data analysis, frequency tables, statistical graphs, binary logistic regression, as well as the technical software Microsoft Excel and SPSS were used.It was concluded that the factors associated with the purchase decision of consumers of an agribusiness company in Peru are: economic, social and psychological factors; demonstrating that, for these types of consumers, the income they have, their environment, their state of mind and the reason for purchase, are the main determinants for resorting to that company. Additionally, the logistic regression model achieved 100% prediction for the purchase decision variable of consumers of an agribusiness company.

An applied, experimental design and cross-sectional research was conducted; an ordinal measurement scale was used for the digital marketing variable and the ratio was applied for the sales variable. The population and sample consisted of 167 customers, and the simple random probability method was used for sampling. A questionnaire and a documentary analysis guide were used to collect the information, respectively. Validity was evaluated by the judgment of specialists and reliability was identified through Cronbach's alpha, whose data were analyzed and processed in the SPSS V 25 program, obtaining a value of 0.850 for digital marketing. The correlation of the variables was determined through the nonparametric Mann-Whitney U test. It was concluded that, by applying digital marketing strategies, the level of sales in a commercial company -Peru was improved, according to the independent samples test the p value isless than 0.05, so the null hypothesis is rejected. For, in the year 2021 a total sale of S/. 498,515.00 was obtained, as opposed to the year 2020 with a total of S/. 332,520.00; which represented an increase with respect to the previous year of S/. 165,995.00 soles. Likewise, it was concluded that the use of digital marketing strategies (4F) is regular in the company and that the indicators with greater emphasis are: functionality and loyalty with 90%, feedback 87% and flow 77%; the same that are of vital importance to increase the sales of this organization.
