Agriculture MCQs cover fundamental and applied concepts related to farming, crop production, soil science, irrigation, fertilizers, plant breeding, pests, and agricultural economics. This topic is designed to strengthen conceptual understanding and problem-solving skills through objective questions. It is especially useful for competitive exams such as PPSC, FPSC, KPPSC, BPSC, NTS, OTS, and other testing services, helping candidates prepare with exam-oriented and up-to-date agricultural knowledge.
