Bengal gram, also known as chickpea, is an important pulse crop grown widely in India, especially during the Rabi season. One of the common questions farmers ask is about the right time to give water to the crop. Proper irrigation is very important in Bengal gram, as both too much and too little water can reduce yield. Since this crop is usually grown on stored soil moisture, careful water management helps in getting a healthy crop and good grain production.
Bengal gram does not require frequent irrigation like some other crops. In many areas, it is grown as a rainfed crop and performs well if soil moisture is conserved properly. However, in dry regions or when rainfall is low, giving water at the right stages becomes necessary. The key point is to avoid unnecessary watering and provide irrigation only at critical growth stages.
The first irrigation is usually given around 25 to 30 days after sowing, if there is no rainfall and the soil becomes dry. This stage is important for proper plant establishment and branching. If enough moisture is already present in the soil, this irrigation can be skipped. Overwatering at the early stage should be avoided, as it can lead to poor root development and increase disease problems.
The most important stage for irrigation in Bengal gram is the flowering stage, which comes around 45 to 55 days after sowing. Water stress at this stage can cause flower drop, leading to fewer pods and lower yield. A light and timely irrigation during flowering helps the crop set more pods and improves overall productivity.
The second critical stage is the pod formation stage, around 65 to 75 days after sowing. At this time, moisture is needed for proper pod development and grain filling. Lack of water during this stage results in small grains and reduced yield. One irrigation at pod formation can significantly improve grain size and weight.
Farmers should be very careful not to over-irrigate Bengal gram. Excess water, especially during flowering and maturity stages, can cause root rot, wilt, and other fungal diseases. Waterlogging even for a short period can damage the crop. Irrigation should always be light, and fields should have good drainage to remove excess water quickly.
Irrigation should be stopped when the crop reaches the maturity stage. Giving water close to harvesting can delay maturity, reduce seed quality, and increase the risk of disease. Dry conditions during maturity help in better drying of pods and easier harvesting.
In summary, Bengal gram needs limited but timely irrigation. One irrigation at flowering and another at pod formation are usually enough in most situations. In dry conditions, an additional irrigation at early growth may be needed. By giving water only when required and avoiding excess moisture, farmers can ensure healthy crop growth, reduce disease problems, and achieve better yields in Bengal gram cultivation.
