Description

The present study was conducted in one of the pea producers of Bonduelle (Portugal) Agroindústria, S.A., in collaboration with the Department of Science and Biosystems Engineering (DCEB) of the Instituto Superior of Agronomia and ADP-Fertilizantes, S.A. The study aimed at evaluating the effect on commercial production and quality of pea, of four experimental treatments, the control without fertilization, and three fertilizer formulations - NPK (20 kg N, 51.4 kg P2O5 and 77 kg K2O per hectare), NPK + PGA (poly-!-glutamic acid and phytohormones) and NPK + Algin (sodium alginate) on commercial production, tenderometric degree (TR) and alcohol insoluble solids (AIS) of garden pea. Statistical analysis revealed no significant differences between treatments and between blocks. However, NPK + Algin led to higher production. NPK + PGA led to the best quality of grain and value to the producer. Treatments with bio-fertilizers and/or biostimulants allowed more regular and homogeneous pea production. The control and NPK showed the highest levels of nutrients in pea.
