For farmers to apply agricultural inputs effectively and safely, they must clearly understand the instructions provided in product literature. Proper comprehension enables them to maximize yield and quality while safeguarding the environment. However, the language used in these instructional materials is frequently scientific and technical. This study investigated whether fifty (50) farmers from Yandev clan in Gboko LGA understood the directions printed on labels and manuals of fertilizers, herbicides, and pesticides used on their farms. Findings revealed that although many farmers use agricultural chemicals, several struggle to interpret the instructions because of their technical nature. A number of respondents also indicated that they do not understand English. Half of the participants supported the translation of instructions into the vernacular. Based on these findings, it is recommended that agricultural input instructions be translated into indigenous languages, particularly Tiv in this context, to enhance comprehension. Additionally, agricultural extension workers should strengthen their efforts in educating farmers on the appropriate and efficient use of agricultural chemicals.
