Behavior of some Soybean Genotypes to Fertilization in the Climatic Condition of 2019

Abstract

Soybeans (Glycine max L. Merril) is the world’s most important seed legume and she is considered a basic food with a high nutritional value. The aim of this study is to evaluate the influence of two types of chemical complex fertilizers (NPK 27:13.5:0 and NPK 16:16:16) with four levels of fertilization (unfertilized, 150 kg/ha, 200 kg/ ha and 250 kg/ha) on the main soybean growing stages in 2019. Field experiments were conducted in the soil and climate conditions of the Agricultural Research and Development Station from Turda. The vegetation stages of the studied soybean genotypes were influenced by: atypical climatic conditions of this year and also the type of fertilizer and the fertilization dose. By analyzing the experimental data, it was noted that one genotype had longer growing season (Raluca TD variety: 135-140 days), and three genotypes had shortest growing season (Perla variety: 122-125 days; Carla TD variety: 121-123 days; T-295 line: 121-123 days).
