Technological innovation in the use of platforms during the pandemic is vital in learning. Therefore, teaching and learning through platforms during the pandemic was investigated. The objective was to know the efficiency of teaching through the use of platforms in the learning of university students. The research is based on the descriptive method with a cross-sectional approach, for which it was questioned what platforms do they use for teaching and learning? Do they understand the topics covered during the classes? And what proposals do you propose to improve teaching through the use of platforms? Once the data for each month was obtained, they were processed using basic statistics. The results determined that in the use of platforms used for teaching, Google Meet stood out with 90%, they understood the teachings through the use of platforms with 90% in June and constant communication as a proposal to improve teaching with 55% in May and June. It is concluded that there was efficiency in the teachings through the use of platforms such as Google Meet and constant communication improves the learning of the university student.

The rise in food, decrease in jobs have affected economic progress. For this reason, research was carried out on the use of market waste for the benefit of the community. The objective was to determine the quantification and chemical characterization for the benefit of the community. It is based on descriptive methodology; Since the waste generated in the Miracle of Barranca market was characterized and classified, and a survey was prepared, what is your proposal on the use of compost based on market waste? Once the data was obtained, they were processed using basic statistics. It was determined that per day it produces organic waste with 65.00%, inorganic with 28.67% and others with 6.33%, and per month organic with 68.13%, inorganic with 26.63% and others with 5.24% of the total of 10,341 tons/month of August and chemical composition. of the compost has adequate concentration of organic matter, low nitrogen, phosphorus, potassium, magnesium and high pH 8.54. In the proposal for the use of compost, 40% stands out for agricultural use. It is concluded that through the catheterization of the waste, 65% organic is produced and when making the compost it has a concentration of nutrients that are favorable to improve the properties of the soil and strengthen the plant. Therefore, the use of compost is a sustainable alternative for agriculture.

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.

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 T1 = 00, T2 = 250, T3 = 500, T4 = 750, T5 = 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 T4 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 T5 with 0.48 g/100 g d.s. (dry material). It is concluded that the T4 dose with 750 mL of phosphorus (Wuxal Phosphorus)/200 L of water increased 13.01% in yield in relation to T1; being significant.
