Evaluación de un biofertilizante a base de rhizobium en la producción del cultivo de arveja (Pisum sativum L.) variedad temprana perfecta

Abstract

The pea crop is one of the main grains grown in Ecuador, and is the third most important legume crop in terms of production and area planted. The present research sought to improve the yield of the pea crop (Pisum sativum L. ) variety Temprana Perfecta, for this purpose, a biofertilizer based on Rhizobium was developed and its effectiveness was evaluated through treatments with different doses (25cc/L, 50cc/L and 100cc/L) and frequencies (8 and 15 days), the trial was conducted in open field, but not clearly in situ, This is to say that the crop was established in potting bags with commercial substrate, because when working with a fertilizer whose main composition is a bacterium, a soil in which the presence of other microorganisms had not been found was needed, thus avoiding any alteration in the rhizosphere of the crop. After the application of the biofertilizer on the crop, data were collected in three different phenological stages of the plant, vegetative development (45 days), flowering (60 days) and green production (95 days), these stages are according to the variety (Temprana Perfecta), since this is early, i.e. its production is before the usual time. The treatment with which the best results were found was variant, both in the phenological stages and in the morphoagronomic characteristics of the crop, but the one with which an excellent yield was obtained was D3F1 (100cc/L, 8 days), with a green production of 7920.40 kg/ha. This was a sufficiently favorable result in the research.
