Resumo

Mycorrhizae, a group of beneficial soil microorganisms that establish symbiotic associations with plant roots, have gained considerable attention in scientific research. A research was conducted from December 2021 to March 2022 in Calao-calao, Don Carlos, Bukidnon sought to investigate the effects of mycorrhizae inoculants and varying fertilizer rates on the performance of sweet corn. It aimed to quantify the concentration of NPK (nitrogen, phosphorus and potassium) on soil planted with sweet corn. The experiment followed a split plot arranged in a randomized complete block design (RCBD) with fertilizer rates as the main plot and mycorrhizal inoculants as the subplot. The entire area was divided into three blocks, each further divided into three main plots measuring 5.25 meters (m) by 16 m. MykoRich was applied at a rate of two capsules per hill, while MykoVam was applied at the rate of 10 g per hill. Both inoculants were applied for their respective hills during planting. For soil analysis, the initial assessment was done before planting and after harvest to determine the total N, extractable P, and exchangeable K. The findings of the study indicate that the presence of mycorrhizae significantly increases the levels of nitrogen (p<0.05) and phosphorus (p<0.001) in the soil. Furthermore, when mycorrhizal inoculants are combined with 75% fertilizer rates, there is an observed elevation in the availability of potassium (p<0.05) in the soil. Finally, a 75% Fertilizer Rate combined with either Mykorich or MykoVam increases the available potassium concentration. Thus, it is recommended to apply MykoVam or MykoRich to increase the available N and P concentration and to apply MykoRich or MykoVAm when fertilizer rates are reduced to 75% to increase the available potassium concentration in the soil.

Keywords: fertilization combination; mycorrhizae; fertilizer rates.

 

Análise de solo plantado com milho doce aplicado com inoculantes micorrízicos e doses variadas de fertilizantes

 

RESUMO: As micorrizas, um grupo de microrganismos benéficos do solo que estabelecem associações simbióticas com raízes de plantas, têm ganhado considerável atenção na pesquisa científica. Uma pesquisa foi realizada de dezembro de 2021 a março de 2022 em Calao-calao, Don Carlos, Bukidnon e procurou investigar os efeitos dos inoculantes de micorrizas e das diferentes taxas de fertilizantes no desempenho do milho doce. Objetivou-se quantificar a concentração de NPK (nitrogênio, fósforo e potássio) em solo plantado com milho doce. O experimento seguiu uma parcela subdividida, disposta em delineamento de blocos completos casualizados (RCBD), com doses de fertilizantes como parcela principal e inoculantes micorrízicos como subparcela. Toda a área foi dividida em três blocos, cada um dividido em três parcelas principais medindo 5,25 metros (m) por 16 m. MykoRich foi aplicado na proporção de duas cápsulas por linha, enquanto MykoVam foi aplicado na proporção de 10 g por linha. Ambos os inoculantes foram aplicados nas respectivas covas durante o plantio. Para análise do solo, a avaliação inicial foi feita antes do plantio e após a colheita para determinação do N total, P extraível e K trocável. Os achados do estudo indicam que a presença de micorrizas aumenta significativamente os teores de nitrogênio (p<0,05) e fósforo (p<0,001) no solo. Além disso, quando os inoculantes micorrízicos são combinados com doses de fertilizante de 75%, observa-se uma elevação na disponibilidade de potássio (p<0,05) no solo. Finalmente, uma taxa de fertilizante de 75% combinada com Mykorich ou MykoVam aumenta a concentração de potássio disponível. Assim, recomenda-se aplicar MykoVam ou MykoRich para aumentar a concentração disponível de N e P e aplicar MykoRich ou MykoVAm quando as taxas de fertilizantes forem reduzidas a 75% para aumentar a concentração de potássio disponível no solo.

Palavras-chave: combinação de fertilização; micorrizas; taxas de fertilizantes.
