Description
Summary:Shallot is one of the leading vegetable commodities that have long been cultivated by <br /> <br /> farmers intensively. The increasing demand and demand for shallot every year can <br /> <br /> not be followed by the increase of production. This is caused by the free factor in <br /> <br /> cultivation of plants such as the diversity of soil types, pest control, disease and <br /> <br /> weeds, fertilization and postharvest handling is not appropriate. One of shallot <br /> <br /> cultivation technology that is being developed is onion cultivation from botanical <br /> <br /> seed or TSS (True Shallot Seed) which has many advantages. But the development of <br /> <br /> this technology is still constrained by the uniform small bulb produced and the dose <br /> <br /> of fertilization is not right. This study aims to determine the effect of NPK 16-16-16 <br /> <br /> and PGPR (Plant Growth Promoting Rhizobacteria) on the productivity of shallot <br /> <br /> small bulb. This research was conducted at screenhouse 1 B in ITB Jatinangor <br /> <br /> campus area, Sumedang regency. The field research was conducted for 16 weeks for <br /> <br /> shallot cultivation process with the observation period was done once every 1 week, <br /> <br /> done after seeding or after 6 weeks old plant. Observations consisted of observations <br /> <br /> of plant height and number of leaves. Then during the harvest period observations <br /> <br /> were made on the overall dry weight of the plant, the overall wet weight of the plant, <br /> <br /> the dry weight of the bulbs, and the diameter of the bulb. The research design is <br /> <br /> Completely Randomized Design (RAL). There are four treatment, treatment A that is <br /> <br /> treatment with NPK 16-16-16 + PGPR 0 g / L, treatment B that is treatment with <br /> <br /> NPK 16-16-16 + PGPR 5 g / L fertilizer, treatment C is treatment with NPK 16 <br /> <br /> fertilizer -16-16 + PGPR 10 g / L, treatment D was treated with NPK 16-16-16 + <br /> <br /> PGPR 15 g / L. The results of this study showed that NPK 16-16-16 + PGPR 5 g / L <br /> <br /> had significant effect on leaf number, wet weight of plant, dry weight of plant, dry <br /> <br /> tuber weight, and tuber diameter, but no significant effect on plant height.
