Evaluating the effectiveness of organic and inorganic liquid fertilizers on growth and development of pepper (Piper Nigrum l.) nursery plants

Abstract

This study aimed to identify the effectiveness of different liquid fertilizers and suitable application intervals for black pepper nursery growth as an alternative to cow dung. The study used three different fertilizers with two different factors variety of fertilizer and fertilizer application rate combined to create nine treatments (F1A1, F2A1, F3A1, F1A2, F2A2, F3A2, F1A3, F2A3, and F3A3) and two control groups. The results showed that the majority of growth parameters were highest in the Bio Green Beper which is an inorganic fertilizer enriched with seaweed extraction and fish emulsion. Specifically, treatments F3A1 and F3A3, which used a potting mix of top soil, sand, and coir dust in a ratio of 2:1:1 and were applied with Bio Green Beper once or three times, showed the highest survival rates among all the treatments. The cost-benefit analysis showed that Bio-Green Beper was the most cost-effective, followed by Albert Solution. Because the usage amount of fertilizer was lower than others. In conclusion, the study demonstrated the effectiveness of using liquid fertilizers as an alternative to cow dung.
