Explore the essentials of Bengal Gram irrigation with these key facts about water needs, suitable methods, timing, and soil factors that affect yield.
At which crop stage does Bengal Gram require the most critical irrigation for healthy growth?
Explanation: During the flowering stage, Bengal Gram is highly sensitive to water stress, making irrigation most critical. Seed treatment and weed removal do not need irrigation, and watering at harvesting is not beneficial. Proper watering at flowering helps maximize yield.
Which irrigation method is generally recommended for Bengal Gram fields to ensure efficient water use?
Explanation: Furrow irrigation is commonly used for Bengal Gram because it supplies water directly to the root zone, minimizing wastage. Flood irrigation often leads to waterlogging and disease. While drip and sprinkler systems can be used, they are less common due to higher costs or unsuitability for wide spacing.
How does soil type influence the irrigation schedule for Bengal Gram crops?
Explanation: Light or sandy soils drain faster, requiring more frequent irrigation for Bengal Gram. Not all soils use the same schedule. Clay soils retain water longer instead of drying quickly, and sandy soils lose moisture faster, not retain it.
What is the general recommendation for irrigating Bengal Gram grown in rainfed regions?
Explanation: In most rainfed areas, Bengal Gram is grown on residual moisture and typically does not need supplemental irrigation. Daily watering and watering at every leaf stage are excessive and impractical. Irrigation at harvest is unnecessary.
Why is over-irrigation harmful for Bengal Gram crops?
Explanation: Excess watering makes Bengal Gram susceptible to diseases such as root rot. While controlled moisture is needed, too much watering does not improve flowering or root strength and can reduce the plant's tolerance to stress.
