Nutrient Management in Pea:

Removal of nutrients by crop:

A crop giving a yield of 4500kg of green pea removes approximately:

• 55 kg of nitrogen,
• 20 kg of phosphorus and
• 40 kg of potash.

Some facts:

• A basal dose of 30 kg N per hectare at planting is sufficient for stimulating early growth.
• Higher dose of nitrogen has adverse effect on nodulation fixation.
• The crop gives good response to phosphorus application as it favours nitrogen fixation by increasing nodule formation. It also increases yield and quality of pea.
• Potassic fertilizers also have effect in increasing the yield and nitrogen fixation ability of the plant.

General Recommendations:

General recommended fertilizer doses depends upon the:

•  Fertility of soil and amount of organic manure applied to the crop.
•  Sowing conditions:
•  Whether field is irrigated or rainfed? and
•  If the crop is rainfed, doses become just half.

How much to apply?

1.  15-20 t/ha of well-decomposed FYM is incorporated into the soil.

                  o N= 20-30kg/ha

                  o 50-60 kg P2O5 and

                  o 50 kg K2O per hectare is recommended for optimum yield.

When to apply?

•  Full dose of N, P and K is given at the time of sowing. 

Region-wise recommendations: At IIVR, Varanasi the maximum yield of Garden Pea cv. Azad P-3 (80.7 q/ha) along with maximum C:B ratio 1:1.32 was recorded with application of FYM @ 10 t/ha + half recommended NPK . Hence, it is recommended for Varanasi conditions. At IIHR, Bangalore, the garden pea variety Arka Kartik recorded the highest yield 105.2 q/ha with the maximum C:B ratio of 1:2.78 with the application of 10 t/ha FYM plus half dose of N:P:K (20:30:25 kg / ha). Hence, it is recommended for Bangalore conditions. At Faizabad, application of neem cake @ 2.5 q/ha plus half of the recommended dose of NPK (15:30:20 kg / ha) recorded the highest mean yield of pod in garden pea cv. Azad Pea-3 (102.10 q/ha) with the maximum C:B ratio of 1:2.98. Hence, it is recommended for Faizabad conditions. For maximum yield (118.79 q/ha) and C:B ratio (1:2.73), 3 irrigations, i.e., at pre-bloom (30 days after sowing), at bloom (50% flowering) and at pod set stages are recommended for the variety Azad Pea-1 under Faizabad conditions. At Bhubaneswar, the integrated application of poultry manure @ 2.5 t/ha + half recommended NPK (25:37.5:25 kg/ha) resulted in 44.16 quintal per hectare pod yield and C: B ratio of 1:1.49. Hence, it is recommended for Bhubaneswar conditions of Orissa. Source: 'AICRP (Vegetable Crops), IIVR, Varanasi'
