Adicionar Tag | Resumo: | The constant and increasing demand for foods such as corn forces producers to use chemical fertilizers, which causes soil degradation, heavy metal contamination, repercussions on microbial communities, and puts human health at high risk. Microalgae can be a potential alternative as biostimulants and biofertilizers, which is why, the objective of this work was to determine the agronomic and productive effect of biofertilization based on microalgae Chaetoceros gracilis and Chlorella vulgaris in the cultivation of corn (Zea mays L.) in Pueblo Viejo, Ecuador. A Completely Random Block Design (DBCA) was taken, to determine the efficiency of the treatments the Tukey Test was taken at 95% probability. Four doses of biofertilizers based on microalgae (5, 10, 15 and 20 mg plant-1) were studied, both for Chaetoceros gracilis and for Chlorella vulgaris, in addition to using an experimental control; 900 plants of corn were used throughout the experiment. The results indicated that, treatment T4, where 20 mg plant-1 of Chaetoceros gracilis was used as biofertilizer, presented the best results in plant height (220.1 cm), ear length (18.17 ± 2.02 cm), number of rows per ear (17.88 ± 1.36), number of grains per ear (652.16 ± 58.23), cob weight with cob (295.03 ± 8.91 g) and the highest yield (9,144.33 kg ha-1). The use of Chaetoceros gracilis at a dose of 20 mg plant-1 improved the agronomic and productive variables of the crop. |
