| Sumario: | World agriculture is facing food demand due to population growth, on the other hand, crops are affected by a number of environmental factors. Faced with these problems, alternatives have been sought that can curb the effects of stress and improve physiological activity, in addition to favoring the improvement of the quality of the fruits. The objective of this research was to evaluate the effect of biostimulants in tomato plants developed under the condition of open field, a random blocks experiment was designed. 1g L-1 of Ca (NO3) 2 and extracts of algae (Ascophyllum nodosum) (An) were applied at 500mg L-1 and at 2500 mg L-1 (3 applications with 15-day intervals) foliar route during the crop cycle Vegetative type variables were taken, fruit quality variables. The application of An obtained a significant increase in the variables Height and stem diameter, on the other hand, the application of Ca (NO3) 2 in combination with An significantly improved the quality of tomato fruits. The application of algae extracts of Ascophyllum nodosum in combination with a mineral such as calcium nitrate in foliar form, favors the metabolic activation of plants, helping regulation, mitigating any type of stress that may arise, thus reflecting the positive effects that are part of a biostimulation generated by calcium. This element improves the quality and firmness of plant tissues. Ascophyllum nodosum is a precursor of secondary metabolism, can activate the defense mechanism supporting stress mitigation and increases the organoleptic properties of plants. |
