Explore essential aspects of tuberose cultivation, from soil requirements to pest management, with this focused horticulture quiz. Perfect for learners aiming to deepen their practical and theoretical understanding of this valued ornamental crop.
Which type of soil is most suitable for optimal tuberose growth and flower production?
Explanation: Sandy loam soil offers the best balance of drainage, aeration, and nutrient availability for tuberose. Heavy clay holds too much water, risking root rot. Highly acidic peat is unsuitable because tuberose prefers near-neutral pH. Rocky alkaline soils can lead to nutrient deficiencies and hinder root development.
In tropical climates, during which months is it generally recommended to plant tuberose bulbs for best results?
Explanation: Planting from February to April takes advantage of warming soil and optimal moisture, encouraging healthy sprouting. June to August may be too wet in monsoon climates, risking bulb rot. October to December and December to January can be too cool, slowing growth.
How should irrigation be managed for tuberose plants grown in well-drained soils?
Explanation: Regular moderate irrigation supports growth without causing root diseases. One-time watering is inadequate for sustained development. Saturated or heavily irrigated conditions promote bulb rot. Proper moisture balance is essential for healthy flowering.
Which pest is most commonly regarded as problematic in commercial tuberose fields?
Explanation: Bud borer caterpillars attack developing tuberose buds, reducing flower quality and yield. Cabbage loopers and Colorado potato beetles typically target vegetable crops, not tuberose. Rice stem borers affect cereal crops and are rarely found in ornamental flower fields.
What fertilizer application is commonly recommended for healthy tuberose growth?
Explanation: A balanced NPK application provides essential nutrients, and extra phosphorus supports root and bulb development. High potassium alone is insufficient for vegetative and reproductive needs. Relying solely on organic manure or omitting fertilizers can lead to nutrient deficiencies and poor flowering.
