Nutrient management is one of the most important factors for getting a healthy and high-yielding Bengal gram (chickpea) crop. Bengal gram is widely grown across India as a Rabi crop and is valued for its high protein content and ability to improve soil fertility. Although it is a legume and can fix nitrogen through root nodules, it still requires proper nutrient support for good growth, flowering, and pod filling. Understanding how to manage nutrients correctly helps farmers improve both yield and grain quality.
Before sowing, it is essential to prepare the soil well. Adding well-decomposed farmyard manure (FYM) or compost at 2–3 tonnes per acre improves soil structure, increases moisture retention, and provides slow-release nutrients. Organic matter also supports beneficial soil microorganisms, which help in nutrient availability and disease resistance.
Even though Bengal gram fixes nitrogen on its own, it requires some nitrogen at the beginning for better establishment. Applying 10–20 kg of nitrogen per hectare as a starter dose helps young plants grow faster until the root nodules become fully active. Excess nitrogen, however, should be avoided because it promotes leafy growth at the cost of pod formation.
Phosphorus is one of the most important nutrients for Bengal gram. It encourages strong root development, early flowering, and better seed formation. Applying 40–50 kg of phosphorus per hectare at the time of sowing gives very good results. Since phosphorus does not move easily in the soil, it should be placed near the seed for better absorption.
Potassium also plays a key role, especially in improving disease tolerance, strengthening the plant, and helping with grain filling. A dose of 20–25 kg potassium per hectare is usually sufficient, depending on soil condition. Fields with sandy or potassium-deficient soils may require slightly higher doses.
Sulphur is another important nutrient that many farmers overlook. Bengal gram has a good demand for sulphur because it improves protein content and enhances the overall quality of grains. Farmers can apply sulphur through gypsum or other sulphur-containing fertilizers. A dose of 20–25 kg sulphur per hectare helps improve yield significantly.
Micronutrients such as zinc, boron, and molybdenum also play an essential role. Zinc deficiency can cause stunted growth and pale leaves. Applying zinc sulphate at sowing or spraying a zinc solution during early growth helps correct this. Molybdenum is particularly important for nitrogen fixation, and a small seed treatment with molybdenum helps improve nodule formation.
Seed treatment with Rhizobium culture and phosphate-solubilizing bacteria (PSB) is strongly recommended. These beneficial microbes improve nitrogen fixation and phosphorus uptake, making nutrient use more efficient. Treated seeds often produce stronger plants and higher yields.
Irrigation management also affects nutrient uptake. Bengal gram requires limited irrigation, usually one or two at flowering and pod formation stages. Over-irrigation can cause root diseases, while timely irrigation improves nutrient absorption.
In simple words, nutrient management in Bengal gram involves using organic manure, adding a small nitrogen starter dose, applying sufficient phosphorus and potassium, including sulphur and micronutrients, and using biofertilizers like Rhizobium and PSB. With balanced and timely nutrition, farmers can achieve a healthier crop, more pods, and higher yields from Bengal gram cultivation.
