AGRONOMIC ANALYSIS OF TWO MAIZE HYBRIDS UNDER THE INFLUENCE OF A BIOFERTILIZER

Abstract

Background. The use of synthetic fertilizers has contributed to environmental pollution and the impact of areas for agricultural use, generating the need to look for ecological alternatives. Currently it has been shown that the application of the commercial biofertilizer Azofert® (Rhizobium leguminosarum, CF1, 1x109 CFU mL-1) increases the growth, development and yield of some crops, including corn, which is of great importance in the world due to its high consumption. Objetive. To evaluate the agronomic response of two corn hybrids (ADV-9789 and Emblema Ultra), under the application of said organic biofertilizer Azofert®. Methodology. A completely randomized block experimental design (BCA) with a bi-factorial arrangement was used, applying doses of 4, 8 and 12 mL Kg-1 seed and a control treatment. Results. It was observed that, in the growth, production and yield variables, the three Azofert® treatments were superior to the control treatment, which assume that the inoculation in seed was efective as a treatment recommendation for this crop. The highest dose (12 mL Kg-1 seed) was the one that presented the significantly higher values in both varieties. Implications. Azofert® is a biofertilizer whose main use is in legumes however, this opens an area of opportunity to study it in other types of crops. Conclusions. The organic biofertilizer Azofert® has a high potential to increase the growth, development and yield of the two corn hybrids studied.
