Abstract

The challenges facing modern plant production involve (i) responding to the demand for food and resources of plant origin from the world's rapidly growing population, (ii) coping with the negative impact of stressful conditions mainly due to anthropopressure, and (iii) meeting consumers' new requirements and preferences for food that is high in nutritive value, natural, and free from harmful chemical additives. Despite employing the most modern plant cultivation technologies and the progress that has been made in breeding programs, the genetically-determined crop potential is still far from being fully exploited. Consequently yield and quality are often reduced, making production less, both profitable and attractive. There is an increasing desire to reduce the chemical input in agriculture and there has been a change toward integrated plant management and sustainable, environmentally-friendly systems. Biostimulants are a category of relatively new products of diverse formulations that positively affect a plant's vital processes and whose impact is usually more evident under stressful conditions. In this paper, information is provided on the mode of action of a nitrophenolates-based biostimulant, Atonik, in model species and economically important crops grown under both field and controlled conditions in a growth chamber. The effects of Atonik on plant morphology, physiology, biochemistry (crops and model plant) and yield and yield parameters (crops) is demonstrated. Effects of other biostimulants on studied in this work processes/parameters are also presented in discussion.

Highlights

The challenge facing modern plant production nowadays is to respond to the increasing demand for food and resources of plant origin by the world’s rapidly growing population
Yield is negatively affected by various adverse environmental conditions and increasing anthropopression and despite employing the most modern plant cultivation technologies and the progress being made in breeding programs, the genetically-determined crop potential is still far from being fully exploited
EFFECT OF ATONIK ON GROWTH AND DEVELOPMENT The results of this study have clearly demonstrated that Atonik affects all stages of plant development

Summary

Introduction

The challenge facing modern plant production nowadays is to respond to the increasing demand for food and resources of plant origin by the world’s rapidly growing population. According to Bray et al (2000), stresses can reduce average productivity by 65–87%, depending on the crop. This makes plant production less profitable for farmers and less attractive for consumers. Biostimulators are a category of relatively new products of diverse formulations that positively affect a plant’s vital processes (Calvo et al, 2014), usually more evident under stressful conditions, by increasing a plant’s tolerance to stresses and repairing damage caused by unfavorable conditions. Biostimulants may be of natural or synthetic origin and consist of various organic and inorganic components. Among others, of plant growth regulators, phenolic compounds, inorganic salts, essential elements, and other substances that have stimulating properties for plants
