PENGARUH BERBAGAI DOSIS PUPUK NPK TERHADAP PERTUMBUHAN DAN HASIL TANAMAN PADI ( Oryza Sativa L.) PADA SISTEM TANAM YANG BERBEDA

ABSTRACT
This research aims to get a better NPK fertilizer in each planting system for the growth and yield of rice plants, to get NPK fertilizer that is suitable for the growth and yield of rice plants and to get a better planting system for the growth and yield of rice plants. The study was conducted in Kotaraya, Ogotion Village, Mepanga District, Parigimoutong Regency, Central Sulawesi Province. The research period starts from July - October 2019. This research was conducted using a two-factor randomized block design. The first factor is that the planting system consists of two stages, namely the Tabela planting system, the transplanting planting system. The second factor is the dose of NPK fertilizer consisting of 5 levels, namely NPK 0 kg ha-1, NPK 150 kg ha-1, NPK 300 kg ha-1, NPK 450 kg ha-1, NPK 600 kg ha-1. Based on the interaction between the NPK fertilizer dosage and the planting care system on the parameters of grading the number of grain permits for the planting system table 450 kg ha-1and tapin planting system 600 kg ha-1, NPK fertilizer application with a dose of 450 kg ha-1high crop yields, the number of offspring maximum, number of productive offspring, age of flowering, number of panicle grains, percentage of empty grains, production of plots of grain, production of woven grain and grain weight of 1000 grains, better balance and transplanting cropping system.
