About Agronomy MCQs
Agronomy is the science of growing field crops efficiently while protecting the land. This section includes questions on crop rotation, mixed and multiple cropping, germination types in crops such as cotton, seed vigour tests like leachate conductivity, and soil practices including solarisation with plastic mulch. Questions on plant nutrients, such as the role of magnesium in chlorophyll, link crop growth to soil fertility.
Environmental and regional issues are also covered. You will see questions on salinity and waterlogging, water erosion in Pakistan, the ozone layer, and insect vectors such as the whitefly that spreads cotton leaf curl virus. Agriculture recruitment exams in South Asia often focus on these practical problems because they directly affect national food production, so knowing them well can give you an advantage.
Key facts to remember
- Cotton seeds show epigeal germination, with the cotyledons pushed above the soil surface.
- Whitefly (Bemisia tabaci) is the vector of cotton leaf curl virus.
- Magnesium is the central atom of the chlorophyll molecule.
- Soil solarisation uses transparent plastic sheets to heat moist soil and kill pests.
- The ozone layer in the stratosphere absorbs most of the sun's harmful ultraviolet radiation.

How to prepare for Agronomy MCQs
- Learn the definitions of cropping systems, including mixed, inter, relay, sequential and multiple cropping, with a local crop example each.
- Group crops by germination type, epigeal or hypogeal, because examiners frequently pick cotton, gram, maize and beans.
- Link each major crop disease to its vector, such as whitefly for cotton leaf curl, to answer pest-related agronomy questions.
- Revise the functions of macro and micronutrients alongside their deficiency symptoms, which often appear together in options.
Frequently asked questions
What are the most important topics in Agronomy MCQs?
Important topics include crop rotation and cropping systems, seed technology and germination, tillage, weed management, irrigation and water use, plant nutrition, and soil problems such as salinity and erosion. Questions about major crops like wheat, rice, cotton, maize and sugarcane, including their sowing times and varieties, are also common in agriculture tests.
How many Agronomy MCQs are on MCQs360?
This category has 307 Agronomy MCQs on MCQs360, and each shows its correct answer as soon as you check it. Practice is free with no sign-up, so you can mix agronomy sessions with soil science, plant breeding and entomology questions in one study plan.
Which exams ask Agronomy MCQs?
Agronomy questions appear in Agriculture Officer, Agriculture Extension and Research Officer tests run by PPSC, FPSC, SPSC, KPPSC and BPSC, and in agriculture lecturer recruitment. In India they feature in ICAR AIEEA and UGC NET agriculture papers, and in Bangladesh in BCS agriculture cadre and other government job tests.
What is the difference between mixed cropping and intercropping?
In mixed cropping, seeds of two or more crops are mixed and sown together without a set row pattern, mainly to reduce the risk of total crop failure. In intercropping, the crops are grown in a definite row arrangement, such as one row of a legume between rows of a cereal, which makes management and harvesting easier.
