YIELD AND ECONOMIC VIABILITY IN A SOYBEAN crop (Glycine max (L.) Merrill) WITH THE APPLICATION OF AMINO ACIDS

Soybean (Glycine max (L.) Merrill) is a crop that has a high demand for all the essential macronutrients. To be used efficiently, these should be at sufficient levels and balanced. The application of amino acids can influence the efficiency of nitrogen fertilisation. The aim of this study was to evaluate the productivity and economic viability of the ‘M-6410 IPRO®’ soybean under different doses of the amino-acid complex, Torped Gold®. Different doses of the organo-mineral class-A fertiliser complexed with amino acids (Torped Gold®) were used. The treatments were arranged in a randomised block design of five treatments with four replications for a total of 20 experimental units. T1 - water applied as control (0.0%), T2 - 80% of the manufacturer’s recommended dose (80%), T3 - 100% of the recommended dose (100%), T4 - 20% more than the recommended dose (120%) and T5 – Double the recommended dose (200%). The lowest production was found for T1 (control), with a productivity of 1495 kilograms per hectare. The manufacturer’s recommended dose (100%), 20% more than the recommended dose (120%) and double the dose (200%) gave a productivity of 1873, 1883 and 1905 kg ha-1 respectively. There was an increase in productivity of the order of 6 bag ha-1 and there was no need to adjust the dose recommended by the manufacturer
