This study intended to find out the impact of project planning on the performance of agriculture projects at Holland Greentech-Rwanda. Hypotheses tested for significance analysis. The target population was Forty-six (46) respondents. The population was small in size a non-probability sampling (Purposive) was used. Collection of primary data using a closed-ended structured questionnaire. The data was coded and entered for analysis using SPSS version 22. A linear regression model was used to relate the study variables at a significance level of 0.05. The results of the study were presented using tables. The findings revealed that project planning has a significant impact on the performance of agriculture projects. It indicated that project planning impacted the performance of agriculture projects with R2 .825. The study found that resource planning has a significant effect on project performance with sig .004. it also found that scheduling has a significant effect on project performance with sig .035. It revealed that budget planning has a significant effect on project performance with sig .006. The study found that risk planning has a significant effect on project planning with sig .015. The fitted model Y=1.95 means that an increase of one unit of resource planning, scheduling, budget planning, and risk planning increases project performance by 1.95. The study concluded that project planning has a significant impact on the performance of agriculture projects as a recommendation to agriculture companies to conduct project planning properly and continuously to improve the performance of agriculture projects.
