The phase was investigated under conditions of temperature 15.03 ±0.31 °C, salinity 36.05 ±0.23 PSU, electrical conductivity 55.95 ± 0.14 mS/cm, irradiance 15.93 ±0.03 µmol m-2 s-1 and subjected to different treatments and control with Bayfolan® fertilizers and hydroponic solution A and B La Molina. Likewise, the results obtained were the maximum Nitrate uptake with Bayfolan® fertilizer and La Molina Hydroponic Solution with 0.1465 mM and 1.369 mM and Phosphate presenting a maximum uptake 0.0312 mM and 0.053 mM, respectively. The experiments were evaluated in a LED germination chamber (TE-4020 Tecnal) programmed for a time interval of 800 hours of settlement of Cigotospora for its growth to conchocelis; in addition, the comparison of means was performed by a Tukey test with a value of p ≥ 0.05, obtaining a growth on the substrate of 4.15 mm2 with the La Molina solution and 1.54 mm2 with the Bayfolan® Solution, but with different coverage of conchocelis on the substrate 49.75% y 63.09%.

Through data analysis it was established that five of the 11 variables under study had statistical significance.

The objective of this study was to evaluate the yield and protein content of Ecuadorian hybrid corn grown in the Santa Catalina Valley, Peru. This research was carried out in the district of Laredo and was based on the evaluation of seven Ecuadorian hybrids introduced in the soil and climatic conditions of the area. Yield and protein content were evaluated including agronomic response variables. The trial consisted of a completely randomized block design with nine treatments and four replications. The comparison of means was carried out by means of a Tukey test with a value of p ≥ 0.05. According to the results, the introduced hybrids showed a positive adaptation with results above the local varieties used as control, with the T2 treatment (DEKLAB 7088) having the highest yield with 8,508.11 kg/ha and the T6 treatment (SOMMA) having the highest protein content of 15.51%. The best responses were achieved by T6 in the variables of days to flowering, plant height and protein content, being the third treatment with the highest yield in kg/ha, which makes it the Ecuadorian hybrid with the greatest potential. This shows the potential of genetic materials developed in other latitudes, having a greater diversity of maize cultivars available for the area.","PeriodicalId":34452,"journal":{"name":"Manglar","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44042309","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
