      The objective of study is to appreciate the influence of different manure of dynamic accumulation of dry substances on the local variety of pea. It has been establish a considerable influence of manure on the photosynthetic potential of plants and photosynthesis production of pea (Pisum Sativum LS).

Methodology and results : four dose, only or combined, Nitrogen, phosphorus, and Potassuim have been brought on the variety plantation local of pea. Organic manure were brought under form of rot manure. The dynamic of increasement daily  means  of dry substance at plantation air during vegetation of pea presented an interest. The resultats show that the  combined contribution (N25 P30 K30) has increased the production of  local variety pea. The analyse of photosynthetic potential of plants of all period of germination to the formation of bud show that, this indication is more arise in the variants with the average dose of NPK and with the use of residual effects of organo-mineral system of 1677,2 m/ha the day to 1685.1 m2 /ha the day. The biggest mass of dry substance of pea plantation is formed during the period full maturity, which is formed in functionof manure dose studied (400,0-576,9 g/m2).

Conclusion : the manure influence positively the increasement of accumulation of the dry substance by the pea plantation. This work illustrate the effect of photosynthetic variations in period of interphase of grains maturity dependent of mineral nutrition  and climatics conditions.
