Assess your knowledge of Jamun cultivation, from optimal planting conditions to common pest management in horticulture. Great for students or those interested in sustainable fruit farming.
Which type of soil is considered most suitable for successful Jamun (Syzygium cumini) cultivation?
Explanation: Well-drained loamy soil offers good water retention and aeration, supporting healthy Jamun tree growth. Heavy clay retains excessive moisture, risking root rot. Sandy saline soil is unsuitable due to poor nutrient content and salt stress. Rocky shallow soils hinder root development, reducing productivity.
What is the most common method used to propagate Jamun trees in commercial horticulture?
Explanation: Seed sowing is the traditional and most widely used method for propagating Jamun, though it leads to genetic variation. Air layering and grafting can be used for uniform plants but are less common commercially. Cuttings of Jamun have low rooting success rates, making them less suitable.
During which months does harvesting of Jamun fruits typically take place in most parts of India?
Explanation: Jamun is usually harvested from June to August when fruits mature after summer flowering. December to February and September to November do not coincide with its fruiting pattern. March to May is generally the flowering period for Jamun, not harvesting.
How often should young Jamun saplings be irrigated for optimal establishment after planting?
Explanation: Weekly irrigation during dry periods supports proper root development in young Jamun saplings. Irrigating only during monsoon is insufficient outside the rainy season. Daily watering can cause root diseases, while monthly is not frequent enough for newly planted saplings.
Which is a common pest that affects Jamun trees, often causing damage to leaves and new shoots?
Explanation: Leaf webber caterpillar attacks Jamun leaves and shoots, reducing photosynthesis and growth. Mango hopper primarily affects mango, not Jamun. Red spider mite and scale insect cause different kinds of damage and are less problematic for Jamun.
