Challenge yourself with key facts about cluster bean cultivation, covering varieties, climate needs, sowing methods, and plant care. Ideal for learners seeking an easy, introductory overview of this important crop.
Which season is most suitable for sowing cluster bean (guar) in most parts of India?
Explanation: Kharif season, corresponding with monsoon rains (June–July), provides the ideal moisture for cluster bean germination. Rabi and winter are too cold and dry; summer can be too hot and water-stressed for good crop establishment.
Cluster bean thrives best in which type of climate condition?
Explanation: Cluster bean prefers warm, semi-arid regions as it is drought-tolerant and sensitive to excessive moisture. Cold and humid or frost-prone areas can stunt its growth, and waterlogged soils increase the risk of root rot.
Approximately how many kilograms of cluster bean seed are recommended for sowing one hectare using line sowing?
Explanation: A seed rate of 20–25 kg per hectare achieves good plant population for line sowing. Higher rates (like 40–50 kg or 60–70 kg) lead to overcrowding, while a lower rate (5–8 kg) may result in gaps and reduced yields.
What type of soil is best suited for successful cluster bean cultivation?
Explanation: Well-drained sandy loam offers good root development and prevents water stagnation which cluster bean cannot tolerate. Heavy clay and waterlogged soils cause root diseases; extremely saline-alkaline soils reduce crop vigor.
Which of the following cluster bean varieties is commonly grown for its high gum content?
Explanation: Pusa Navbahar is a widely preferred variety known for high gum yield and adaptability. Arka Suman is less known for gum, Wheat 101 is not a cluster bean, and Rajma Select pertains to kidney beans.
