THE EFFECT OF VARIATIONS OF PLANTING DISTANCES AND FERTILIZATION OF HUMAN URINE LIQUID ORGANIC FERTILIZER ON ONION GROWTH
Growth is a process of increasing volume that is irreversible (cannot be reversed), and occurs due to the increase in the number of cells and the variation of each cell. In the process of growth accompanied by changes in shape. Good growth will result in maximum production. This research was conducted in Sunggal North Sumatra from February to April 2022. This study used a factorial randomized block design (RAK) with 2 factors, namely variations in spacing such as 15 cm x 15 cm, 20 cm x 20 cm, 25 cm x 25 cm and 30cm x 30cm. factor 2, namely liquid organic fertilizer human urine, namely 0, 100, 200, 300 ml/l.air/plot. The results showed that the variation in spacing showed a significant effect where the best variation was 15 cm x 15 cm.
