Inoculação de fungos micorrízicos em fertilizante organomineral no desenvolvimento de Triticum turgisecale

Abstract

The composting and granulation of animal manure in agricultural properties and the addition of inorganic mineral fertilizers results in organomineral fertilizer that associated with arbuscular mycorrhizal fungi (AMF) can increase the efficiency of the nutritional effect of fertilizers on the morphological and physiological parameters of the plant. However, there is still doubt about the possibility of performing the inoculation during the granulation of the organomineral fertilizer without the loss of viability of the mycorrhizal fungi and whether the use of the mycorrhizal organomineral fertilizer contributes to the development of triticale. Thus, the general objective of this work was to evaluate inoculation methods and the effect of mycorrhizal inoculum in an organomineral fertilizer and its relative efficiency in relation to the mineral fertilizer, in Triticum turgisecale. To this end, two scientific studies were carried out, the first of which aimed to determine the effect of different methods of inoculation of arbuscular mycorrhizal fungi in organomineral fertilizer on the development of triticale; the second aimed to study the efficiency of mycorrhizal organomineral fertilizers and the mycorrhizal dependence on morphological and physiological parameters of triticale. The results showed that the mycorrhizal fungi inoculated in the organomineral fertilizer showed good viability and efficiency, especially the inoculum Rhizoglomus clarum. The inoculation methods in GS60 and GS105 for Rhizoglomus clarum and GSA for Gigaspora margarita showed better responses in relation to mineral fertilizer for crude protein of the shoot. The inoculation process in the organomineral fertilizer contributes to the development of triticale, when compared to the noninoculation, increasing grain yield and biomass production, when inoculated in AGROM and GS60 for Rhizoglomus clarum and GSA for Gigaspora margarita. Inoculation with both inoculums also provides greater production of protein in the grain, shoots and total plant, mainly with inoculation in GS60 and GS105 for Rhizoglomus clarum and GSA for Gigaspora margarita.
