Abstract

A planting media composition consisting of ultisol soil, composted sugar cane residue (blotong)and husk charcoal is needed to support the growth of sugarcane (Saccharum officinarum L.) seedlings from bud chips. The aim of this research was to determine the comparison of the planting media composition consisting of the ultisol, blotong and husk charcoal on the growth of sugar cane (Saccaharum officinarum L,.) seedlings from Bud Chips in Polybags. This research used a completely randomized design (CRD) with one treatment factor, i.e. the planting media composition consisting of ultisol, blotong and husk charcoal with the following volume ratio: V1 = (1 l) + (0.5 l) + (0.5 l), V2 = (0.5 l) + (0.5 l) + (1 l), V3 = (0.5 l) + (1 l) + (0.5 l), V4 = (0.67 l) + (0.67 l) + (0.67 l). Each treatment was repeated 3 times. The parameters observed were plant height, stem diameter, shoot dry weight and root dry weight, as well as the root shoot ratio. The result showed that the comparison of the planting media composition   for ultisol, blotong and husk charcoal, in treatment V3 = (0.5 l) + (1 l) + (0.5 l) had a significant effect on plant height of 201.30 cm with an increase of 29.795%, stem diameter 21.77 mm with an increase of 38.92%, shoot dry weight 44.73 g with an increase of 158.55%, root dry weight 5.29 mm with an increase of 153.11%, root crown ratio 8.47 with an increase of 51.52 %.

Abstract

The cultivation of cocoa plants that began in nurseries, is an effort to increase cocoa production. High yields can be achieved with high-quality cocoa beans. This study aims to obtain a combination treatment of NPK inorganic fertilizer with the best Bioneensis bioorganic fertilizer to support the growth of cocoa seedlings. This study used a one-factor Complete Randomized Design. The treatment design tested was Bioneensis bioorganic fertilizer and NPK fertilizer with 5 levels of dosage and 3 replications. as follows:  b0 : Control, b1 : 7.5 g NPK fertilizer, b2 : 9.9 g Bioneensis fertilizer, b3 : 5 g NPK fertilizer (66.7% of b1) + 3.3 g of Bioneensis fertilizer (33.7% of b2), and b4: 2.5 g NPK fertilizer (33.7% of b1) + 6.6 g of Bioneensis fertilizer (66.7% of b2). and b4: 2.5 g NPK fertilizer (33.7% of b1) + 6.6 g of Bioneensis fertilizer (66.7% of b2). Implementation of research in the form of land preparation and shade,  preparation of planting media,  seedling preparation, feeding, treatment, and maintenance of plants. Plant height, stem diameter, header dry weight, root dry weight, root crown ratio, and quality index are the parameters that are measured. The results of this study concluded that treatment of 2.5 g of NPK fertilizer combined with 6.6 g of Bioneensis biofertilizer will increase plant height by 60.10%, rod diameter by 43.86%, The dry weight of the header was 183.31%, the dry weight of the roots was 229.41%, and the quality index was 189.20% compared to the control.Â
