The use of biostimulants in coffee seedlings can promote gains in their growth and quality. Thus, this study aimed to evaluate the growth and quality characteristics of Coffea arabica seedlings under the effect of the nicotinamide and Azospirillum brasilense application. The experimental design was randomized blocks with treatments arranged in a 5 × 2 factorial scheme, with four replicates. The treatments resulted from the use of five doses of nicotinamide (0, 30, 60, 90, and 120 mg L-1 of water) combined with the absence and presence of Azospirillum brasilense applied to Coffea arabica seedlings from Catuaí Vermelho 144 cultivar. Plant height, stem diameter, number of leaves, leaf area, shoot dry mass, root dry mass, plant height:stem diameter ratio, shoot:root dry mass ratio, plant height:shoot dry mass ratio, and Dickson quality index were evaluated. The combined or isolated use of A. brasilense and nicotinamide, up to a dose of 33.5 mg L-1, increased the biometric characteristics and dry mass accumulation. However, using nicotinamide doses between 30 and 61.8 g L-1 increased the quality of Coffea arabica seedlings. The synergistic effect of the use of A. brasilense and nicotinamide was verified for the growth and quality of Coffea arabica seedlings.

“…Biostimulants are defined as mixtures of natural or synthetic plant regulators, chemical compounds (vitamins and nutrients), algal extracts, microorganisms, and amino acids (Frasca et al, 2020;Araújo et al, 2021). These products can improve crop yield and quality (Colla et al, 2021;Vendruscolo & Lima, 2021).…”

The use of biostimulants in second-crop maize (Zea mays) can promote higher physiological activity in plants, resulting in higher grain yield. This study aimed to evaluate the effects of phytohormones and nicotinamide on growth and yield traits of second-crop maize. The statistical design used was a randomized block design arranged in a factorial scheme with two doses of phytohormones (0 and 500 mL ha-1) × five concentrations of nicotinamide (0, 200, 400, 600, and 800 mg L-1) with four replications. The use of biostimulants favored all variables evaluated for the maize crop. The isolated use of phytohormones and nicotinamide promoted grain yields of 6089.6 and 6242.5 kg ha-1, respectively, representing gains of 6.0 and 11.6%, respectively, compared with the control. The application of 800 mg L-1 nicotinamide resulted in the highest maize grain yield. The use of phytohormones and nicotinamide, isolated or associated, was favorable for the growth characteristics and grain yield of second-crop maize. A synergistic effect was noted between phytohormones and nicotinamide on the first ear insertion height and number of rows per ear.

“…The use of Azospirillum as a biological fertilizer can reduce the use of chemical fertilizers by up to 20% without reducing the yield obtained. In addition, biofertilizers can be produced at a low cost so as to increase farmers' profits [8,9]. be developed as a biofertilizer in plants because it contains IAA which can increase root elongation, increase root hairs, and plant root surface area [10,11,12,13,14].…”

Azospirillum is one of the bacteria that can be used as biological fertilizer because the bacteria is known as a producer of PGPR (Plant Growth Promoting Rhizobacteria) which can increase crop production in a sustainable manner. Another potential possessed by Azospirillum is as a biocontrol agent for controlling plant pathogens. The application of Azosprillum in agriculture, especially food crops, is still very limited on a small scale. The purpose of this paper was a literature review that reviews the potential of Azospirillum as a biofertilizer and biocontrol of pathogens in food crops with a focus on its application and impact on the productivity sector. The methodology used a search for literature related to the topics listed in the search for current and relevant information about the use of bacteria of the genus Azospirillum in the cultivation of food crops. Among the studies, selected reports on the use of bacteria from the genus Azospirillum in food crops, which may contain results obtained in the field or in a controlled environment. The conclusion was that field inoculation has not been a major area of Azospirillum research at present, recent field and greenhouse experiments, especially in cereals and rice plant, have once again shown promising potential. The use of Azospirillum bacteria to improve the quality and quantity of food crop products and develop environmentally friendly practices is a reality. However, the development of research that determines the best strategy for the use of this technology in food crops should continue, aiming at the best conditions for producers.
