The doses used were 2.5, 5 and 7 mEq L-1 and were applied at the stages of beginning of flowering, full flowering, end of flowering, fruit setting and full production. The design of the experiment was randomized blocks in four replicates, each replicate consisted of a 1 m2 area, with 16 plants. An analysis of variance was performed and the Tukey´s test (p≤0.05) was applied for comparison of means.\u0000Results: the results indicated that doses of 2.5 mEq L-1 for the 'Monterrey' cultivar and 5 mEq L-1 for the 'Albion' cultivar favored increases in total phenols, total flavonoids, total anthocyanins, antioxidant capacity and higher yields, by obtaining 13 kg m-2 and 12.59 kg m-2 from those cultivars, respectively.\u0000Findings/ Conclusions: this indicates that the use of nano-calcium as a foliar fertilizer could be a suitable alternative that helps improving the bioactive compounds and yields of strawberry fruits.","PeriodicalId":153856,"journal":{"name":"Agro Productividad","volume":"46 9","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141355326","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}

Deterministic and stochastic estimations for production volume, milk price, and cattle inventory from 2021 to 2030 were established using confidence intervals to construct pessimistic (lower interval), base (mean), and optimistic (upper interval) scenarios. \u0000Results: The evaluated period witnessed an estimated 10.27% increase in production, equivalent to 576 million liters of milk, with an average annual growth rate of 1.0922%. Milk prices displayed an upward trend, with average prices of $0.66, $0.69, and $0.72 under pessimistic, base, and optimistic scenarios, respectively. In 2030, a 22% price increase compared to 2021 was observed. Considering a base price of $0.45 USD per liter in 2030, costs under pessimistic, base, and optimistic scenarios were $1,658.21, $1,756.43, and $1,855.31, resulting in profits of $1,160.75, $1,229.50, and $1,022.45 from milk sales. Cattle inventory exhibited an upward trend, paralleling milk volumes and prices. \u0000Limitations on study/implications: The study's use of a univariate method may incompletely capture market dynamics complexity, potentially underestimating the impact of external market forces and global economic conditions on milk prices. \u0000Findings/conclusions: To secure forecasted milk volumes in base and optimistic scenarios, maintaining and enhancing good management practices is crucial.
