Plant growth regulators are key players throughout the life of the plants. This work investigates the use of different growth regulators (auxins, gibberellins and cytokinins) applied joint with another growth regulator, discovered four decades ago and with enormous potential in agriculture, triacontanol, on field pea (Pisum sativum L.). Commercial doses of the growth regulators were mixed with triacontanol in order to evaluate the positive and/or negative interaction in the tested variables: plant height, number of branches per plant, pod length and pod width, number of pods per plant, number of grains per pod, total fresh plant weight and fresh grain yield. The analysis of variance indicates that there are significant differences between treatments in the variables plant height, number of pods per plant, number of grains per pod and fresh grain yield. The highest yields were obtained with the application of triacontanol plus auxins, gibberellins and cytokinins (12150 kg ha-1), as it had 3.5 branches per plant, 14.67 pods per plant and 8.74 grains per pod; and the application of triacontanol plus auxins and cytokinins (10534 kg ha-1). Applied with triacontanol, the auxins increased yield and their components while the gibberellins increased plant height and pod width, the cytokinins showed a stimulating effect in all variables. It was also observed that auxins and cytokinins act synergistically in almost all evaluated variables since their combined effect exceeds the effect of each growth regulator separately. A positive correlation was shown between yield and morphological variables, except for plant height and pod width that showing a negative correlation did not show significant statistical correlation. It was also observed that treatments with triacontanol almost always outweigh the control, except in the number of branches and number of pods per plant indicating the great potential of this growth regulator in sustainable agriculture and their use will ensure food security in the next years.
