Explore the key features, benefits, and uses of Dhaincha seed in sustainable agriculture. This quiz tests your knowledge across cultivation, benefits, and identification of Dhaincha within farming practices.
What is the main purpose of using Dhaincha seed in agricultural fields?
Explanation: Dhaincha is mainly grown for green manuring to improve soil fertility by adding organic matter and nitrogen. While grains and wool come from other crops and animals, its use as an insect repellent is limited and not the primary role.
When is the ideal time to sow Dhaincha seeds for green manure purposes in most Indian regions?
Explanation: Dhaincha is best sown before the onset of monsoon to ensure adequate moisture for seed germination. Sowing in winter, autumn, or late monsoon risks poor growth or missed timing for maximum soil benefits.
Which type of soil is Dhaincha best suited for cultivation as green manure?
Explanation: Dhaincha is well adapted to saline and waterlogged conditions, where few other green manure crops thrive. Rocky, acidic forest, or peaty soils are less suitable due to poor growth or incompatibility.
What benefit does Dhaincha provide to soil through its root nodules?
Explanation: The root nodules of Dhaincha harbor nitrogen-fixing bacteria, enriching soil nitrogen content. It does not produce edible roots, mainly prevents erosion by biomass cover rather than wind, and does not increase soil acidity.
Which plant characteristic helps identify Dhaincha in a field?
Explanation: Dhaincha is identified by its slender, compound leaves with many narrow leaflets. It does not have edible tubers, red flowers or smooth bark, nor broad leaves with purple veins.
