- Abstract
The research was carried out during 2018-2020, at R & DSPCS Dăbuleni and focused on the reaction of the sorghum plant for grains to the fertilization regime, depending on the size of the nutrition space. The obtained results highlighted the fact that the sorghum for grains capitalized with good results the pedoclimatic conditions in the area of sandy soils. There was a positive correlation between fertilization and biometric parameters of the sorghum plant. Fertilization with N150P80K80 + ALBIT, applied foliar at a dose of 40 ml / ha, in the phase of 6-8 leaves of the plant, determined, compared to unfertilized, the growth by 19.1-20.6 cm, at the height of the plant, by 5, 7-7 mm, at the diameter of the stem, by 2.36-3.5 cm, at the length of the panicle and by 0.97-1.66, at the leaf area index, depending on the number of plants per unit area. Between the production obtained from grain sorghum and the plant nutrition regime there is a positive correlation, distinctly significant (r = 0.991 **), which highlights production increases, which exceed the limit difference of 5%, compared to unfertilized.
