Cropping Systems MCQ for ICAR-JEF, ICAR-SRF, ICAR-NET, IBPS-AFO/SO, Pre-PG, BHU Pre-PG, IFFCO-AGT, CCI, FCI, B.sc, M.sc, etc. Here are 20 multiple-choice questions (MCQs) related to cropping systems, with answers and explanations. These cover concepts such as monocropping, crop rotation, mixed cropping, intercropping, relay cropping, and more: Question 1: What is the definition of monocropping in agriculture? Answer: A. Growing only one crop on a piece of land year after yearExplanation: Monocropping involves growing a single crop on the same land for consecutive years. It can deplete soil nutrients and increase pest and disease vulnerability. Question 2: Which of the following is a common disadvantage of monocropping? Answer: B. Increased susceptibility to pests and diseasesExplanation: Continuous monocropping creates an environment for pests and diseases to thrive, as there’s no crop diversity to disrupt their life cycles. Question 3: What is the primary principle behind crop rotation? Answer: A. Growing different crops in succession on a piece of land over a specific periodExplanation: Crop rotation helps maintain soil health by alternating crops with different nutrient needs, reducing soil depletion and disease cycles. Question 4: Which of the following is a key principle of crop rotation? Answer: A. Leguminous crops should follow non-leguminous cropsExplanation: Legumes fix nitrogen in the soil, which benefits subsequent non-leguminous crops, improving soil fertility. Question 5: What is mixed cropping? Answer: A. Growing multiple crops on the same piece of land at the same timeExplanation: Mixed cropping involves cultivating different crops simultaneously on the same field to optimize resources and reduce the risk of total crop failure. Question 6: What is intercropping? Answer: A. Growing multiple crops in alternating rows or patterns within the same fieldExplanation: Intercropping optimizes space and resources, allowing crops with complementary growth habits to share the same field. Question 7: What is relay cropping? Answer: A. Planting a second crop before the first crop is harvestedExplanation: Relay cropping increases land use efficiency by starting a second crop while the first is still growing, leading to continuous production. Question 8: What is multistoried cropping? Answer: A. Growing crops at different heights in the same field to maximize spaceExplanation: This system maximizes vertical space by growing taller crops alongside shorter crops, optimizing light and resource use. Question 9: What is sole cropping? Answer: A. Growing only one crop on a piece of land during a specific periodExplanation: Sole cropping refers to cultivating a single crop on a field during a specific period or season, without combining it with other crops. Question 10: What is sequence cropping? Answer: A. Planting two or more crops in sequence on the same piece of land in a single yearExplanation: Sequence cropping maximizes land use by planting multiple crops sequentially in one year, increasing overall productivity.
