Abstract
This field research was conducted from June to August 2022 at the research station of Agriculture Extension, Mesuji District, Mesuji Regency, Lampung Province, Indonesia. The study aimed to determine the effect of nitrogen fertilization and irrigation on different levels of treatment on shallot growth and yield in dry land. The experiment was a factorial design in a striped plot with three replications. The first factor was nitrogen fertilizer levels, namely 0 kg N/ha (N0), 80 kg N/ha (N80), 160 kg N/ha (N160) and 240 kg (N240); the second factor was irrigation with four levels, namely 25% ETc (W25), 50% ETc (W50), 75% ETc (W75) and 100% ETc (W100). The variables observed were plant height, number of leaves, fresh weight of tubers, diameter of tubers, dry weight of tubers and harvest index. The results showed that the significant effect of treatment was more due to the main effect of nitrogen fertilizer and irrigation factors. Nitrogen fertilizer has a significant effect on plant height, fresh weight of tubers, tuber diameter, dry weight of tubers and harvest index, while the number of leaves and canopy cover have not been significantly affected. The irrigation treatment significantly affected all observed variables, while only the dry weight variables of tubers showed a noticeable interaction effect of nitrogen fertilization and irrigation. The best treatment to support the growth and yield of shallots in dry land results from fertilizing nitrogen (N) 160 kg N/ha and irrigating 75% Etc
