Status, popular varieties ,cultivation aspects of field pea

Field pea (Pisum sativum L.) is a significant cool-season leguminous pulse crop predominantly grown for its protein-rich dry seeds. Its cultivation serves both nutritional and agronomic purposes, including soil nitrogen enrichment through biological N₂ fixation and meeting rising demands in plant-based protein markets globally.

Status of Field Pea Cultivation

Field pea enjoys wide cultivation mainly across temperate zones such as Canada, Russia, China, Europe, and parts of India and Africa. Canada ranks as the largest exporter, particularly of yellow and green varieties, supplying global markets focused on sustainable protein sources. In India, field pea (locally termed "Matar") is primarily a Rabi season crop cultivated over northern and central states like Uttar Pradesh, Madhya Pradesh, Bihar, Rajasthan, and Maharashtra. India maintains high internal demand, which limits export volumes despite considerable production.

Increasing consumer awareness about plant-based proteins, environmental sustainability, and crop rotation benefits has led to steady global uptake of field pea crops in diverse agro-ecologies.

Popular Varieties

Varietal selection is critical to optimize yield, disease resistance, and adaptation. Internationally prominent semi-leafless and lodging-resistant cultivars such as CDC Amarillo, CDC Striker, CDC Meadow (Canada), and Kaspa (Australia) have been widely adopted for their agronomic robustness and market preference.

In India, cultivars are released mainly by ICAR and state agricultural universities. Popular varieties include:

• Rachna: Powdery mildew resistant, widely cultivated in northern India.
• Hans: Early maturing with lodging tolerance.
• HFP 4 (Aparna): Known for higher yields and disease resistance.
• Pant P-5: Mid-season variety with medium seed size.
• JP 3430 and KPMR 400: Adapted for late sowing and diverse agro-climatic zones.

Breeding emphasis continues on disease resistance, specifically towards powdery mildew, Aphanomyces root rot, and ascochyta blight, as these are widespread constraints for field pea production [1][2][3][4].

Cultivation Aspects

Climate and Soil: Field pea is highly adapted to cool, temperate climates with an optimum temperature range of 15–25°C. It is susceptible to frost damage during flowering and heat stress during pod filling. Well-drained loamy soils with neutral to slightly acidic pH (6.0–7.5) are ideal; waterlogging and salinity are detrimental.

Sowing and Seed Rate: Seed rates generally range from 50 to 70 kg/ha, adjusted according to seed size and planting density preferences. In India, sowing is typically done in October-November during the Rabi season. Recommended spacing is around 30 cm between rows and 10 cm between plants to optimize light penetration and airflow.

Land Preparation: Requires fine seedbeds achieved through 2-3 ploughings and leveling to ensure proper seed-soil contact and drainage.

Nutrient Management: Field pea benefits from basal phosphatic fertilization, commonly applying 20–25 kg N and 50–60 kg P₂O₅ per hectare. Atmospheric nitrogen fixation by symbiotic Rhizobium can supply a substantial portion of nitrogen needs, thus excessive nitrogen fertilizer is to be avoided. Inoculation with Rhizobium leguminosarum is strongly recommended; studies show soil-applied granular inoculants result in improved nodulation and N accumulation compared to seed-applied inoculants, enhancing fixation efficiency [5].

Irrigation: The crop usually requires 2–3 irrigations, emphasizing the branching and pod development stages. Adequate moisture during flowering and pod filling stages critically influences yield.

Weed Management: Weeds severely impact early growth; mechanical weedings or pre-emergence herbicides like pendimethalin are common during the first 45 days.

Pest and Disease Management: Pea stem fly, aphids, and pod borers are principal insect pests. Fungal diseases such as powdery mildew, rust, ascochyta blight (caused by Didymella pinodes, Phoma koolunga et al.), and root rots including Aphanomyces root rot severely affect yield and quality. Use of resistant varieties (e.g., Rachna, Hans) combined with integrated pest management, seed treatments, fungicides, and optimized sowing time/density reduce disease severity [1][2][3][4].

Harvesting: Timing is crucial; pods mature and turn yellow at harvest. Delays lead to pod shattering and seed quality losses. Average yield ranges 15–20 quintals/ha, with improved varieties and management pushing yields higher.

Nitrogen Contribution and Residual Benefits

Field pea fixes significant atmospheric nitrogen through symbiosis, which improves soil fertility not only for its own growth but also benefits succeeding non-legume crops. Residual soil N benefits measured in Canadian studies show an effect equivalent to 12–28 kg N/ha available for the following crop, depending on soil and climatic conditions [6][7]. This underscores field pea’s value in sustainable crop rotations, especially in temperate cereal-based systems.

Nutritional and Economic Importance

Field pea seeds are nutritionally rich, containing ~20–25% protein, comprising essential amino acids, carbohydrates, fiber, vitamins, and minerals. The protein fraction (especially from yellow peas) has favorable functional properties for food processing and is increasingly utilized in protein isolates and plant-based food products [8][9]. Agriculture-wise, field pea supports soil health via nitrogen fixation, diversifies cropping systems, and offers economic returns both as food and feed.

In summary, field pea is a vital pulse crop globally and in India, with diverse improved varieties tailored to different agro-ecologies and uses. Optimizing cultivation through variety selection, climate-appropriate sowing, effective inoculation, nutrient and disease management, and harvest timing can sustain and improve yields. The crop’s role in nitrogen fixation and increasing demand in health-conscious markets enhances its future prospects for sustainable agriculture.
