Abstract

This research aims to find out the production of ponelo variety rice crops at various doses of nitrogen fertilizer and the amount of seeds needed to be planted on local superior ponelo rice cultivation Gorontalo. This research was for 4 months starting from December 2019 to April 2020 located in Iloheluma Village Tilongkabila District Bonebolango Gorontalo Province. This study used randomized group design (RAK) factorial first factor with the application of nitrogen fertilizer consisting of 3 levels namely N0=control (without fertilization), N1=75 kg/ha and N2=150 kg/ha. The second factor with the treatment of the number of seeds needs to be planted consisting of 2 treatments namely ( A1) 2 seeds need planting and (J2) 3 seeds need to be planted, each treatment is re-treated 3 times so that in obtaining 18 units of experimental plot, by observing 15 sample plants in each plot, so that there are 270 sample plants in total. The area of the experiment plot is 2m x 3m. the variables observed are the number of productive puppies, the length of malai, the weight of 1000 grains, and the production of grain Results show that the intercation of treatment 150 kg / ha and 3 seeds of planting need to limit the number of productive feeders, the longest malai length is found in the treatment of 150 kg / ha, the treatment of 75 kg / ha with the number of seeds 3 planting needs shows the average weight of grain 1000 best grains, and the highest production is found in the treatment of 75 kg / ha with the number of seeds 2 needbang planting
