Use of organic and mineral fertilizer on the morphology and yield of the crop of soy (Glycine max L. Merrill) Panorama P29

Abstract

Soy is a legume of Asian origin, its composition is high in protein, consumed as a source of nutrients in human and animal feed. This crop needs to absorb a significant amount of nutrients for its growth and yield. The lack of adequate fertilization means that soy producers do not obtain the expected production and quality. The objective of this research was to evaluate the morphological behavior and yield of the Panorama P29 soybean variety through the use of organic and mineral fertilizer. A completely randomized block design with four treatments and three repetitions was used, for the comparison of means the Duncan test was used at P≤0.05. The treatments used were: control, organic fertilizer, N-P-K and N-P-K-S, the variables evaluated were: plant height and load, days to flowering, maturation and harvest, number of pods, seeds per plant and yield. The results obtained showed that there was no statistical difference in the morphology of the plant except for the load height variable, the highest yield was with the N-P-K-S mineral application with an average of 2,284.33 kg·ha^-1. With the use of organic fertilizer, it was possible to obtain 2 t·ha^-1, causing an increase in crop yield.
