Abstract

White oyster mushroom (Pleurotus ostreatus) requires a source of nutrients for growth and development. The provision of NPK fertilizer aims to increase the source of media nutrients so that the results obtained are better in quantity and quality. Growth regulators can stimulate the relatively long growth of oyster mushroom mycelium. Growth regulators contain hormones that can support growth rates. One alternative natural growth regulator that can be used is coconut water. The research was carried out at the oyster mushroom kumbung at Pekanbaru, using a completely randomized design, consisting of 2 factors and three replications. The first factor was NPK fertilizer consisting of 4 levels (0, 7.5, 10, 12.5) g per baglog. The second factor was coconut water consisting of 4 levels (0, 3, 6, 9) ml per baglog. Data were analyzed using Analysis of Variance and further tested using DNMRT level 5%. The results showed that adding 10 g of NPK fertilizer and 6 ml of coconut water per baglog was a better dose for the number of fruit bodies, fresh fruit body weight, fruit cap diameter, fruit stalk length, and biological efficiency.

Abstract

Red chili is a commodity that must be developed in the Riau, which is mostly ultisol soil. Rice husk biochar as an ameliorant can increase plant growth. Also the bacteria Paenibacillus sp. can solubilize unavailable phosphate to become available for red chili plants. This study aimed to know the best doses between the combination of rice husk biochar and phosphate solubilizing bacteria Paenibacillus sp. on the growth of red chili plants. The study was conducted at the experimental farm of the Faculty of Agriculture, the University of Riau from January to May 2021, using non-factorial and randomized completely design, then tested with Duncan's new multiple range test (DNMRT). The combination factor is rice husk biochar and phosphate solubilizing bacteria Paenibacillus sp.: 0 g/polybag + 0 ml (B1); 0 g/polybag + 15 ml (B2); 0 g/polybag + 30 ml (B3); 0 g/polybag+ 45 ml (B4); 210 g/polybag + 0 ml (B5); 210 g/polybag + 15 ml (B6); 210 g/polybag + 30 ml (B7); 210 g/polybag + 45 ml (B8); 420 g/polybag + 0 ml (B9); 420 g/polybag + 15 ml (B10); 420 g/polybag + 30 ml (B11); and 420 g/polybag + 45 ml (B12). Parameters observed were plant height, stem diameter, number of branches, number of leaves, leaf width, number of flowers, and root dry weight. The results showed that the combination of 420 g/polybag rice husk biochar and 45 ml bacteria Paenibacillus sp. affected both the vegetative and generative growth of red chili plants.
