Role of Calcium in Plants

Role of Calcium in Plants:- Calcium is an essential plant nutrient. It has many roles:

Participates in metabolic processes of other nutrients uptake.
Promotes proper plant cell elongation.
Strengthen cell wall structure – calcium is an essential part of plant cell wall. It forms calcium pectate compounds which give stability to cell walls and bind cells together.
Participates in enzymatic and hormonal processes.
Helps in protecting the plant against heat stress – calcium improves stomata function and participates in induction of heat shock proteins.
Helps in protecting the plant against diseases – numerous fungi and bacteria secret enzymes which impair plant cell wall. Stronger Cell walls, induced by calcium, can avoid the invasion.
Affects fruit quality.
Has a role in the regulation of the stomata.

Nutrient Management in Pea:

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 depend upon the:

How much to apply?

15-20 t/ha of well-decomposed FYM is incorporated into the soil.
For the better yield in pea use 10 kg Urea, 50 kg DAP, 15 kg MOP and 6 kg Sulphur 90% per acre during the land preparation use the half quantity of urea and the full quantity of remain fertilizer and remaining quantity of urea used in two split doses during the irrigation.
