Bengal gram, also known as chana or chickpea, is an important rabi crop grown widely across India. It is valued for its high protein content and is a major source of income for many farmers. However, the crop often faces several growth problems during its life cycle. These issues can affect plant height, branching, flowering, and pod formation, ultimately reducing yield. Understanding the common growth problems in Bengal gram and their causes can help farmers take corrective steps at the right time.
One of the most common growth problems in Bengal gram is poor germination. This usually happens when seeds are sown in dry soil, during delayed sowing, or when low-quality seeds are used. Soil moisture is very important during sowing because the seed requires enough water to sprout properly. If germination is uneven, the field may have gaps, leading to reduced yield.
Another major issue is stunted growth, where the plant does not grow to its normal height and produces fewer branches. This problem is often linked to nutrient deficiency, especially phosphorus. Bengal gram requires good root development, and insufficient phosphorus results in weak plants. Zinc and sulphur deficiency can also slow down growth.
Moisture stress is a common challenge. Bengal gram is sensitive to both too little and too much water. If the crop faces water shortage during the early vegetative stage, branching is reduced. If it faces drought during flowering or pod formation, severe flower and pod drop may occur. On the other hand, excess water or waterlogging can damage the roots and cause diseases like wilt.
Root rot and wilt diseases are among the biggest threats to Bengal gram growth. These diseases weaken the plant from below the soil, making it dry and yellow. Wilt often leads to sudden plant death, creating empty patches in the field. These problems usually arise in fields with continuous chickpea cultivation, poor soil drainage, or infected soil.
Pest attack, especially from the gram pod borer, affects growth indirectly. When larvae feed on leaves and tender shoots, plant vigor decreases. Severe attack reduces branching and delays flowering. Early control of pests is important to avoid long-term damage.
Flower drop and poor pod setting are also common growth issues. These occur due to sudden temperature changes, nutrient imbalance, and moisture stress. High temperatures during the flowering stage cause flowers to dry and fall. Lack of boron and molybdenum also affects flower formation.
Weed competition is another common problem, particularly during the first 30–40 days after sowing. Weeds compete with the crop for sunlight, nutrients, and water, slowing plant growth significantly. Timely weeding ensures that Bengal gram plants receive adequate resources to grow.
Finally, improper sowing time also affects the overall growth of the crop. Late sowing exposes the crop to high temperatures during flowering, while very early sowing may expose seedlings to frost.
By understanding these problems—poor germination, nutrient deficiencies, moisture stress, diseases, pests, and weeds—farmers can take timely action to ensure healthy growth. Proper field preparation, balanced fertilizers, timely irrigation, crop rotation, and pest management all help Bengal gram reach its full potential and give better yields.
