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: T<sub>1 </sub>= 0, T<sub>2</sub> = 0.50 L, T<sub>3</sub> = 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 T<sub>4</sub> 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, T<sub>4</sub> with 1 L Silicon (Sil Trade) / 200 L of water increased 8.58% of the yield in relation to T<sub>1</sub>.</p> Henry Christopher Angeles José Antonio Legua Cárdenas Marco Antonio Jamanca Ramirez Miguel Angel Inga Sotelo José Yovera Saldarriaga Félix Gil Caro Soto Elvira Teófila Castañeda Chirre Javier Eugenio Gómez Gamarra Dante Daniel Cruz Nieto Copyright (c) 2021 Journal of Sciences and Engineering https://creativecommons.org/licenses/by/4.0 2021-08-21 2021-08-21 5 2 38 47 10.32829/sej.v5i2.134 Effect of phosphorus doses to obtain higher yields in the cultivation of garlic (Allium sativum L.), at the district of Barranca [Efecto de las dosis de fósforo para obtener mayor rendimiento en el cultivo de ajo (Allium sativum L.), en el distrito de Barranca] https://www.journals.cincader.org/index.php/sej/article/view/138 <p>The research deals with phosphorus fertilization to obtain higher yields in garlic cultivation. The objective was to determine the appropriate dose of foliar phosphorus fertilization, to obtain a higher yield in garlic cultivation. The methodology is based on applied and experimental research; Therefore, the Completely Random Block Design was used, composed of 4 blocks and 5 treatments which were T<sub>1</sub> = 00, T2 = 250, T<sub>3</sub> = 500, T<sub>4</sub> = 750, T<sub>5</sub> = 1000 mL of phosphorus (Wuxal phosphorus)/200 L. water and were applied 15, 30 and 45 days after sowing. They were evaluated from sowing to postharvest and the data were processed with analysis of variance and Duncan. Likewise, phosphorus concentrations in leaves were analyzed. The results determined that T<sub>4</sub> stood out in stem length with 35.28 cm, commercial yield with 11.208 tn/ha, bulb weight with 34.28 g, number of bulblets with 13 and foliar analysis highlighted T<sub>5</sub> with 0.48 g/100 g d.s. (dry material). It is concluded that the T<sub>4</sub> dose with 750 mL of phosphorus (Wuxal Phosphorus)/200 L of water increased 13.01% in yield in relation to T<sub>1</sub>; being significant.</p> Lady Milagros Vergara Santillan José Antonio Legua Cárdenas José Vicente Nunja García Marco Antonio Jamanca Ramirez Miguel Angel Inga Sotelo Javier Enrrique Sotelo Montes Javier Eugenio Gómez Gamarra Dante Daniel Cruz Nieto Copyright (c) 2021 Journal of Sciences and Engineering https://creativecommons.org/licenses/by/4.0 2021-09-23 2021-09-23 5 2 48 57 10.32829/sej.v5i2.138 A challenge to build the professional profile of the public manager in Perú [Un desafío para construir el perfil profesional del gestor público en Perú] https://www.journals.cincader.org/index.php/sej/article/view/140 <p>The objective of the research was to analyze the profile of the public manager in Peru. Methodology: Qualitative approach, case study. The population consisted of 6 participants who are public managers in the education sector from different hierarchical levels, who agreed to participate voluntarily. An interview with in-depth open-ended questions was conducted. The results: the participants expressed that the public manager leader who manages must maintain communication and consensus with argumentation, reflecting on work performance to achieve objectives and efficiency. Likewise, most managers indicated that they are not evaluated through performance evaluation instruments or rubrics. However, what is perceived periodically is that the fulfillment of commitments and goals to be achieved annually is evaluated. On the other hand, they share the idea that feedback is important to identify and solve some work situations that limit management. It is concluded that the profile of public managers of high pedagogical positions in the educational sector lacks an evaluation with validated instruments. In view of this situation, it is necessary to socialize the evaluation rubrics with the managers. It should be noted that, in practice, it is perceived that job performance is being evaluated by goals and objectives. Pedagogical specialists maintain the need to strengthen general competencies in the labor field, not only at the beginning of their entry and at the end of their appointment, but to do so continuously, with emphasis on sustaining a highly competent management that raises the quality of the services provided in the educational sector.</p> Mónica Liliana Agüero Ynca Monica Elisa Meneses- La-Riva Copyright (c) 2021 Journal of Sciences and Engineering https://creativecommons.org/licenses/by/4.0 2021-10-12 2021-10-12 5 2 58 69 10.32829/sej.v5i2.140
