Effect of the application of organic amendment and microorganisms that promote plant growth on tomato production (Solanum lycopersicum L.)

Abstract

It is important to conserve and improve water use efficiency and crop productivity in arid and semi-arid zones. For which, the use of beneficial microorganisms and water retainers can help in the tolerance of plants to drought conditions. Therefore, the objective of this work was to determine the effect of inoculation with MPCV- plant growth promoting microorganisms (Azospirillum brasilense and mycorrhizal fungi) and the application of organic amendment of potassium acrylate on the production of tomato plants (Solanum lycopersicum L.). A greenhouse trial was carried out with a completely randomized experimental design with 4 treatments (T1: Control without application of amendment or MPCV; T2: application of K acrylate amendment; T3: with MPCV inoculation; T4: with joint application of K acrylate amendment and MPCV), with 15 replicates. The highest production and size of tomato fruits was achieved with the inoculation of MPCV (T3) and with the application of K acrylate (T2) individually. The inoculation with Azospirillum brasilense and mycorrhizal fungi, and the application of the organic amendment of potassium acrylate at the time of transplanting tomato (Solanum lycopersicum L.) improves growth and increases its production.

Effect of native strain of Azospirillum brasilense in the production of horticultural seedlings in semihydroponic system of culture in bag

“…In addition, better quality seedlings were observed in the inoculated treatments for the three species under study (pepper, tomato, and basil), given their size and vigor. Seedlings with agronomic characteristics like those observed by Andrada et al, 8 when cultivating tomato (Solanum lycopersicum L.) under greenhouse conditions. 15 days after planting, the emergence of pepper seedlings of the two varieties began, registering significant differences in favor of the inoculated treatment in pepper inoculated and highly significant differences in favor of the inoculated treatment with increases of 55% in Padrón pepper (Figure 4).…”
