The effect of sprinkler irrigation system on shallot growth and yields in dry land of Sigi district

Shallot (Allium ascalonicum L.) cultivation is conducted on dry land and requires irrigation. A pressurized irrigation system which is highly water efficiency was suitable in on dry land. The study purpose is to determined irrigation system effect on the growth and yield of shallot. The research location was Kotarindau Village, Dolo subdistrict, Sigi in April-June 2019. The study used a Randomized Block Design (RBD) in 3 (three) treatment of irrigation systems (I1 = permanent sprinkler irrigation, I2 = portable sprinkler irrigation and I3 = conventional irrigation) in 5 (five) repetitions. The shallot variety is Tajuk. Observations were plant height, tillers, plants and tubers in fresh weight, plants and tubers in dry weight, and yields. Data were analyzed using variance at 5% and DMRT test. The results showed that the application of permanent sprinkler irrigation systems (except plant height and number of tillers) gave the best results when compared to portable sprinkler watering systems and conventional irrigation.
