Abstract
Rice Inpari-IR-Nutri Zinc is a biofortified product with a high zinc content compared to other types of rice. This study aimed to obtain the best planting system and the number of seeds in increasing the growth and yield of Inpari IR Nutri Zinc. This study used a Divided Plot Design which was repeated four times. There was a total of 32 treatment combinations. The planting system (S) is placed as the main plot consisting of S1 (4: 1 Legowo Planting System) and S2 (Tile Planting System), while the number of seeds (J) as sub-plots consists of J1 (1 seed), J2 (3) seeds), J3 (3 seeds) and J4 (7 seeds). The planting system and the number of seeds had a significant effect on the variables of plant height, total tiller number, number of productive tillers, the weight of 1,000 seeds, panicle length, and rice production of Inpari IR Nutri Zinc. The use of seeds of 1 and 3 plants produced 4.74 and 4.60 tons/ha. The legowo 4: 1 planting system had 4.88
Highlights
Efforts to increase rice production to achieve food security continue to encourage the government to achieve sustainable food self-sufficiency
Inpari Nutri Zinc rice variety is a variety that is rich in Zn content and functions to overcome stunting
The purpose of the study was to determine the effect of the planting system and the correct number of seeds to increase the production of lowland rice (Oryza sativa L.) Inpari IR Nutri Zinc variety to obtain the best planting system and the number of seeds in improving growth and yield of Inpari IR Nutri Zinc
Summary
Efforts to increase rice production to achieve food security continue to encourage the government to achieve sustainable food self-sufficiency. Biofortification is carried out to increase the nutritional value and overcome the iron deficiency in people It is namely assembling rice varieties with high Zn content. Based on the description data issued through the Decree of the Minister of Agriculture in 2019, the Zn content in this variety is 34.51 ppm while other varieties such as Ciherang contain 24.06 ppm. These advantages are expected to contribute to the success of the government's program in overcoming zinc deficiency and minimizing stunting in Indonesia
