ABSTRACT Biochar, which has emerged as an important form of the transformation and final disposal of biomass, can be used directly in soil or in seedling nurseries. In this study, the use of biochar of different particle sizes and percentages was evaluated in replacement to a conventional substrate used in the production of sugarcane seedlings. To this end, an experiment was carried out based on a completely randomized design, with a 5 × 4 factorial scheme, consisting of five different percentages of biochar (with 0, 25, 50, 75, and 100% v/v substitution of the conventional substrate) and four particle sizes (<1, 2, 4, and 9 mm), with nine repetitions. As seedling growth variables, the average sprouting time, sprouting speed index, plant height, leaf number, leaf length, and width + 2, as well as the dry mass of the aerial parts and roots were evaluated. Irrespective of the percentage of commercial substrate replaced with biochar, sprouting time was found to be shorter when 6-mm-diameter biochar particles were used. With respect to the sprouting speed index, it was found that regardless of particle size, the highest value occurred when biochar was used to replace 42% of the commercial substrate. The substitution of the commercial substrate with biochar had the effect of reducing the growth of sugarcane seedlings.

Cayenne pepper is one of the important economic agricultural commodities and is widely used in the food industry. However, the presence of cayenne pepper seeds is not favored by some people because if consumed can cause digestive disorders. Giberelin is one of the growth regulating substances commonly used to produce seedless fruit growth. This study aims to explore the effect of water hyacinth root extract (Eichhornia crassipes) on plant height, yield and number of cayenne pepper seeds. The study was carried out experimentally using a completely randomized design (CRD) of 4 extract treatments, namely 0 g / l (control), 25 g / l, 50 g / l, and 75 g / l of water hyacinth root extract, each of which was repeated six times. The results of this study indicate that the provision of water hyacinth root extract can increase plant height and yield but reduce the amount of cayenne pepper seeds. The concentration of water hyacinth root extract 75 g / l is the best water hyacinth root extract that can produce an average plant height of 65.67cm, an average yield of 206.50 fruits per plant with an average fruit yield of 170.17 gram per plant and the average number of seeds is 31.17 seeds per cayenne pepper. This study concluded that the root extract of goiter water can reduce the number of seeds and increase plant height and yield of cayenne pepper. Keywords: cayenne pepper, giberelin hormone, water hyacinth and cayenne pepper seeds.
