Use of tomato plants as biosensors in greenhouse fertirigation systems

Abstract

Numerous studies conducted in the fundamental fields of nutrition and irrigation are based on the phyto-chemical relationship between plants and the environment, a relationship that is reflected in technologies and, subsequently, in the quality and quantity of production. Research highlights the relationship between the value gradient of an electric current measured in the stem of tomato plants and the degree of water supply and nutrient solutions Eleven experimental variants had the role of highlighting the potential for variation of the electric current in the Brillante F1 tomato cultivar. The best results of the electric current, also reflected in the tomato production, were obtained at the level of V 8 variants (mix of potassium sulphate calcium nitrate potassium chloride) and V 9 (mix of applied solutions) at the time of application of the solutions nutrients and irrigation, to prevent the occurrence of abiotic stress.
