Dataset on the use of biostimulants in strawberry cultivation under tropical

The application of biostimulants presents a viable strategy for enhancing strawberry productivity and fruit quality under tropical conditions. These organic substances can improve nutrient uptake, stimulate plant growth, increase stress tolerance, and enhance overall fruit quality. The strawberry production system in Paraguay is characterized by low yields, and producers lack access to the new varieties available. The objective of this research was to assess how different biostimulant doses affect the productivity and quality of strawberry varieties. The experiment was conducted at the National University of Asunción's Horti-Fruit Center, Faculty of Agrarian Sciences, during March-July 2022. The treatments consisted of a combination of seven varieties of strawberry with three levels of biostimulants. The experimental design was subdivided into plots with a bifactorial arrangement (7x3), where Factor I was the three doses and Factor II was the seven varieties. Each treatment had four repetitions, and each experimental unit consisted of four plants. The variables evaluated were commercial fresh mass of fruits per plant, total and commercial yield per m2, total and commercial number of fruits per plant, average fruit mass, average commercial fruit mass, diameter and length of the fruit, and content of soluble solids. Totals, titratable acidity, pH and firmness. The data were subjected to analysis of variance and the Tukey test at 5% error.在热带种植环境中，施用生物刺激素（biostimulant）是提升草莓产量与果实品质的可行方案。这类有机物质可促进植株养分吸收、刺激生长、增强抗逆性，并全面改善果实综合品质。当前巴拉圭的草莓生产面临单产偏低的困境，且种植者难以获取当前可用的优良新品种。本研究旨在探究不同剂量的生物刺激素对不同草莓品种产量与果实品质的影响。试验于2022年3月至7月在亚松森国立大学（National University of Asunción）农业科学学院园艺与水果研究中心开展。试验设置7个草莓品种与3个生物刺激素剂量梯度的组合处理，采用双因子（7×3）裂区试验设计，其中因子I为生物刺激素3种剂量，因子II为7个草莓品种。每个处理设置4次重复，每个试验单元包含4株草莓植株。本次试验测定的指标包括：单株商品果实鲜重、每平方米总产与商品果产量、单株总果数与商品果数、平均单果重、平均商品果重、果实横径与纵径，以及可溶性固形物含量、可滴定酸含量、pH值与果实硬度。试验数据采用方差分析，并以5%显著水平进行Tukey检验多重比较。
