Explore your understanding of fennel cultivation and horticulture basics, from planting to harvest. Discover key concepts every grower should know about this aromatic crop.
Which climate conditions are best suited for successful fennel cultivation in the field?
Explanation: Fennel thrives in mild and cool climates, which promote vegetative growth and prevent premature bolting. Hot and arid conditions can stress plants, while high humidity increases disease risk. Cold and frost-prone areas may damage fennel plants and reduce yields.
Fennel grows best in which type of soil for optimal bulb and seed development?
Explanation: Well-drained loamy soil provides the ideal balance of nutrients and water retention for fennel. Heavy clay restricts drainage, leading to rot. Acidic peat lacks necessary minerals and is too moist. Rocky sandy soil drains excessively and is often nutrient-poor.
Which method is most commonly used to propagate fennel in agricultural settings?
Explanation: Direct seeding is preferred due to fennel's long taproot and limited transplant tolerance. Root cuttings are ineffective, grafting is not suited for fennel, and tissue culture is rarely used outside of research contexts.
For fresh bulb fennel, harvesting should occur at what plant stage?
Explanation: Harvesting when bulbs are firm and swollen ensures the best flavor and texture. Waiting until flowering or seed formation leads to woodiness and bitterness. Harvesting too early or after germination gives underdeveloped bulbs.
Which practice helps prevent aphid infestations during fennel cultivation?
Explanation: Regular crop rotation helps break pest life cycles and maintains healthy soil. Overhead irrigation can encourage humidity-loving pests. Constant shade slows growth and reduces vigor. Excess nitrogen increases susceptibility to some pests and weakens the plant structure.
