In order to valorise the entire genetic yielding and quality potential of the yellow bell pepper cultivar or hybrid we need, besides ensuring optimal conditions of growth and development achieved technologically, special measures of stimulating flower fecundation which, under the impact of some negative factors abort, thus diminishing production. Research was carried out on competitive comparative crops, in a glasshouse, using a tri-factorial experiment set after the sub-divided plot method with three replications. Experiments aimed at studying hybrids under the impact of the interaction between experimental factors (Factor A – the cultivated hybrid, Factor B – the fertirrigation system with soluble fertilisers such as Kemira and Agriplant, and Factor C – type of stimulation of plant metabolism and flower fecundation with natural and synthesis preparations). Experimental results were processed with mathematical statistic calculus specific to the variance analysis method, resulting in significant yield differences on the ground of comparisons as a result of the interaction of the experimental factors. The three bell pepper hybrids under study, subjected to foliar treatments with a natural foliar fertiliser (Bionex) and with a bio regulator (Solex), are Italian; their destination is mainly industrial, due to the fruit features, but they are also destined to be consumed fresh. The conclusions of our analysis show that there is unilateral impact and interaction between experimental factors, which leads to the necessity to modernise cultivation technology in bell pepper. Modernity, in this case, is represented by the use of chemical fertilisers such as Kemira and Agriplant and by the idea of using natural foliar fertilisers and bio regulators whose range is more and more diversified. It is recommendable to use the fertilisation system Kemira on the studied hybrids since the yields obtained under the impact of this factor are statistically covered, with very significantly positive differences in yield. Natural or synthesis products used to stimulate plant metabolism and flower fecundation have a beneficial effect on bell pepper yields, that are higher than those of the control (not fertilised) with yield increases between 14.1 and 29.3%. The paper points out the level of the production thus obtained and its quality under the impact of some natural and synthesis products that stimulate plants’ metabolism and flower fecundation in the studied hybrids.
