Abstract

In nursery technology, the storage of scions always requires approriate optimization of shelf life and good packing This study aims to determine the effect of shelf life and storage materials on viability of soursop (Annona muricata) var. Ratu grafting by applying randomized factorial design with 2 factors: storage time and type of packing materials, with 3 times repeatation. The duration of storage time factor consist of 5 levels: 0 day, 3 days, 5 days, 1 week and 2 weeks meanwhile packing materials factor consist of 2 levels: parafilm and polyethylene. The highest survival rate was obtained at 0 day shelf life time and parafilm as storage material, whereas the lowest one was shown at 2 weeks storage with polyethylene as storage material.

Abstract

Mustard high-yield plantation are mostly supported by utilization of inorganic fertilizer. However, this couldincrease soil acidity and give negative impact to the environment. Biochar, a soil amendment, has potential asa valuable tool for the agricultural with ability to help build soil, conserve water, and sequester carbon. Further,biochar could be as well combined with biofertilizer to increase soil nutrient. This study aims to understand theinfluence of combining biochar with biofertilizer on mustard yield plantation..Ten groups of combination wascarried out on this study namely P1: without fertilizer (control), P2:biochar, P3:NPK, P4:biochar + bacteria,P5:biochar + mycorrhizal, P6:biochar + NPK, P7:biochar + bacteria + NPK, P8:biochar + mycorrhizal + NPK,P9:biochar + mycorrhizal + bacteria, P10:biochar + bacteria + mycorrhizal + NPK. The addition of biochar onbiofertilizer showed significantly increasing of mustard biomass and yield by 6,85 gram and 12015 kg/harecpectively.
