Explore fundamental techniques and best practices involved in groundnut sowing to ensure healthy crop establishment. This quiz covers timing, seed spacing, soil preparation, and more for beginners in agriculture.
In most tropical regions, when is the most suitable period to sow groundnut seeds for optimal growth?
Explanation: Groundnut seeds need adequate moisture and warmth, making the start of the rainy season ideal. The dry season offers insufficient water, and cold winter months can hamper germination. Sowing after the rice harvest might be too late for proper groundnut establishment in many areas.
Which of the following row and plant spacing combinations is generally recommended for groundnut sowing?
Explanation: A spacing of 30 cm between rows and 10 cm between plants allows good air flow and root development. Wider spacings like 75 cm x 30 cm reduce plant density, while narrower spacings, such as 10 cm x 10 cm, can lead to overcrowding. 50 cm x 10 cm is less common for groundnuts.
Why is it recommended to treat groundnut seeds with fungicide before sowing?
Explanation: Treating seeds with fungicide helps prevent fungal infections during early growth. It does not influence seed size, speed up harvesting, or improve seed color. Disease protection is the main benefit for healthy crop establishment.
Which soil type is best suited for groundnut sowing to achieve good germination and pod development?
Explanation: Sandy loam offers good drainage and aeration, which are essential for groundnuts. Heavy clay retains too much water, leading to poor growth; saline soil can stunt plants; and waterlogged silt is unsuitable for healthy root and pod formation.
At what depth should groundnut seeds typically be sown for effective emergence?
Explanation: A sowing depth of 5 to 6 cm ensures the seed is covered but not too deep to impede emergence. Shallower planting, like 1 cm, exposes seeds to birds and drought, while deeper options, such as 10–12 cm or 12 cm, can slow or prevent germination.
