Pea is an important rabi season legume crop grown widely in India for vegetables, dry grains, and fodder. Proper fertilizer management is essential to get good plant growth, more pods, and higher yield. Although pea is a leguminous crop and can fix nitrogen from the air, it still needs balanced nutrition, especially during early growth stages. Applying the recommended fertilizer dose at the right time helps farmers achieve better productivity and soil health.
The first step in fertilizer management for pea is soil preparation. Pea grows best in well-drained loamy soil with good organic matter. Before sowing, the field should be ploughed well and mixed with well-decomposed farmyard manure or compost. Organic manure improves soil structure, increases moisture-holding capacity, and supports beneficial soil microorganisms. This creates a good base for healthy root growth.
Pea mainly requires three major nutrients: nitrogen, phosphorus, and potassium, but the quantity of nitrogen required is lower compared to non-legume crops. Nitrogen is important for early vegetative growth, but excess nitrogen should be avoided. Too much nitrogen leads to excessive leaf growth, delayed flowering, and poor pod formation.
For pea crop, a small starter dose of nitrogen is recommended at sowing time. This helps seedlings grow well until nitrogen-fixing nodules develop on the roots. Once nodulation starts, the plant meets most of its nitrogen requirement naturally. Applying nitrogen beyond the recommended level is unnecessary and may reduce yield.
Phosphorus is one of the most important nutrients for pea. It helps in root development, nodule formation, flowering, and pod development. Adequate phosphorus ensures strong plants and good yield. Phosphorus should always be applied as a basal dose at the time of sowing, as it does not move easily in the soil.
Potassium helps improve plant strength, disease resistance, and pod quality. It supports better water regulation in the plant and helps peas tolerate stress conditions like cold and moisture imbalance. Potassium is also applied as a basal dose during land preparation.
In general, the recommended fertilizer dose for pea under normal soil conditions includes a moderate amount of nitrogen along with sufficient phosphorus and potassium applied before sowing. If soil fertility is high, fertilizer quantity can be adjusted accordingly.
Pea also responds well to secondary and micronutrients. Sulfur is important for protein formation and improves grain quality. Zinc and boron play a role in growth and pod formation. Deficiency of these nutrients leads to poor growth and fewer pods. If deficiency symptoms are seen, they can be corrected through soil application or foliar sprays in small quantities.
Seed treatment with beneficial bacteria helps improve nitrogen fixation. Treated seeds form healthy root nodules, which supply nitrogen naturally and reduce fertilizer requirement.
Water management is closely linked with fertilizer use. Nutrients are absorbed efficiently only when adequate soil moisture is present. Over-irrigation should be avoided, as it reduces root activity and nutrient uptake. Light and timely irrigation during flowering and pod formation supports better fertilizer response.
Weed control is important to ensure that nutrients are used by the pea crop and not by weeds. Early weed removal improves crop growth and fertilizer efficiency.
In conclusion, the recommended fertilizer dose for pea includes the use of organic manure, a small starter dose of nitrogen, adequate phosphorus, and sufficient potassium applied at sowing. Supplying sulfur and micronutrients when needed, along with proper irrigation and weed control, helps farmers grow a healthy pea crop with good yield and quality.
