Biostimulators Impact Germination and Leaf Development of Capsicum annum cv. Alexander – a BBCH Scale Assessment
Yeast and coffee grounds were tested as biostimulators on pepper growth. The main aim was to emphasize the growth differences when these two biological agents were added. A number of 40 microcosmos experiments were set up with yeast (D1-3) and coffee ground (C1-3) in three concentrations 1, 2, and 3%, a mixed treatment (MIX) with the middle concentration (2%) and a control (C) treatment in five repetitions. The growth and development were reported on BBCH scale. The yeast (D1) produced 48% of the seedlings in 14 BBCH, D2 produced 16% seedlings in 18 BBCH. The coffee grounds C1 (11 BBCH) and C2 (12 BBCH) produced 12% fewer seedlings than the control treatment. Seedlings from the MIX treatment were at the end very similar with D3 treatment with the higher achievement of 35% in 14 BBCH. Pepper seedlings’ growth and development were easily visible between different treatments tested.
