Bio-Forge promotes growth and yield performance of pechay (Brassica rapa L. var. chinensis (L.) Hanelt)

The aim of the study was to test the effectiveness of the fertiliser available on the market - Bio-Forge® on the growth and yielding of Chinese cabbage (Brassica rapa L. var. chinensis (L.) Hanelt). In the experiment, not only the Bio-Forge fertiliser was used, but its action in combination with other fertilisers was tested. T1 - was control group consisted of plots fed with distilled water and precipitation. Group of T2 was consisted of recommended rate (RR) of inorganic NPK fertiliser according to soil analysis used in the experiment. The test of T3 was available on the fertiliser market - Bio-Forge fertiliser. The T4 group consisted of T2 + S (simulate as a yield enhancer which contained a combination of 3 different phytohormones including cytokinin (0.009% / 1L), gibberellic acid (0.005% / 1L), and indole-3-butyric acid (0.005% / 1L). Treatment of T5 was consisted of T2 + Bio-Forge. The treatment 6 - T6 was S + Bio-Forge and T7 = T2 + T6. Based on the observations, it was found that the Bio-Forge fertiliser alone had a positive effect on the growth and yielding of pechay, but to a lesser extent than in combination with other growth stimulants and mineral fertilisers. Compound fertilisers significantly stimulated plant growth, increased fresh weight and contributed to better yielding.
