Abstract

The purpose of this research was to study the effect of nutrient concentration and inoculation of biological agents (PGPR and AMF) in a hydroponic system of substrate culture on the growth and yield of cherry tomato plants. The greenhouse research was conducted in the Agrotechnopark of the University of Brawijaya at Jatikerto Village, Kromengan Sub-District, Malang Regency. The utilized research method was Completely Randomized Nested Design consisting of two factors. The first factor was the concentration of nutrient solution consisting of 100 % (3.5 dS m-1), 75 % (2.6 dS m-1), and 50 % (1.8 dS m-1) concentrations. The second factor is the inoculation of biological agents consisting of no inoculation of biological agents, PGPR (Plant Growth Promoting Rhizobacteria), AMF (Arbuscular Mycorrhizal Fungi), and PGPR + AMF. The data were analyzed using an analysis of variance and continued with the test of Honest Significant Difference at 5 % level. The results showed that the interaction between the types of biological agents and nutrient concentrations significantly increased the number of flowers, number of fruits, fruit weight, fruit diameter, and sugar content of cherry tomatoes. The AMF application showed the highest fruit weight per plant and fruit diameter, especially at 100 % nutrient concentration. The AMF application also showed a higher sugar content compared to the control and PGPR but not significantly different from the PGPR + AMF treatment at all levels of given nutrient concentration. Fruit weight per plant with treatment of AMF, PGPR + AMF, and PGPR respectively produced 64.47, 48.75 and 29.39 % higher than without application of biological agents.

营养浓度及接种PGPR和AMF对水培樱桃番茄产量和果实品质的影响

本研究旨在研究基质水培系统中营养浓度和生物制剂（PGPR和AMF）接种对樱桃番茄植株生长和产量的影响。温室研究是在位于马朗县Kromengan街道Jatikerto村的Brawijaya大学农业技术园进行的。所采用的研究方法是由两个因素组成的完全随机嵌套设计。第一个因素是营养液的浓度，包括100%（3.5 dS m-1）、75%（2.6 dS m-1）和50%（1.8 dS m-11）的浓度。第二个因素是接种生物制剂，包括不接种生物制剂、PGPR（植物生长促进根细菌）、AMF（丛枝菌根真菌）和PGPR+AMF。使用方差分析对数据进行分析，并继续进行5%水平的诚实显著差异检验。结果表明，生物制剂类型与营养浓度的相互作用显著增加了樱桃番茄的花数、果数、果重、果径和含糖量。施用AMF表现出最高的单株果实重量和果实直径，尤其是在100%营养浓度下。与对照和PGPR相比，施用AMF也显示出更高的糖含量，但在给定营养浓度的所有水平下，与PGPR+AMF处理没有显著差异。AMF、PGPR+AMF和PGPR处理的单株果重分别比不施用生物制剂处理高64.47%、48.75%和29.39%。
