Effect of silicon’s doses in the cultivation of pea (Pisum sativum L.), to obtain a higher yield, district of Barranca [Efecto de dosis de silicio en el cultivo de arveja (Pisum sativum L.), para obtener mayor rendimiento, distrito de Barranca]

The objective was to determine the adequate dose of silicon foliar fertilization, to obtain a higher yield in pea crops. Regarding the methodology, the research is applied and experimental; Therefore, the Completely Random Block Design comprised of 4 blocks and 4 treatments was used, which were: T1 = 0, T2 = 0.50 L, T3 = 0.75 L and T4 = 1 L Silicon (Sil Trade) / 200 L of water Applied in four times, it is worth mentioning the chemical ingredient of silicon is orthosilicic acid. The physical characteristics from sowing to harvest were evaluated and the silicon concentrations in leaves were analyzed by treatment. Obtained data were processed by analysis of variance and Duncan. The results determined that T4 stood out in plant height with 89.74 cm, number of pods per plant with 37, weight of pods per plant with 234.43 g, yield with 4444.4 kg/ha and silicon concentration in leaves with 1.75 g/100 g of dry material. It is concluded that there were no silicon effects; that is, it did not statistically influence the physical characteristics. However, T4 with 1 L Silicon (Sil Trade) / 200 L of water increased 8.58% of the yield in relation to T1.
