Abstract

Climate change that occurs requires secondary irrigation, to meet water needs by plants from existing water sources (springs, or existing irrigation. This study aims to see the effect of irrigation on increasing the production of shallot bulbs of the Lansuna variety. The study was conducted in the dry season of 2017 in Minahasa Regency. The layout of the experiment used a Randomized Block Design 2 treatment with 5 replications per plot measuring 4m x 4m. Pressurized watering was carried out per day for 4 hours with watering intervals every 3 days. For comparison, the existing technology only depends on the rainfall that occurs. randomized so that there are 250 clumps to be analyzed. This can also be seen in the existing 0.5 ha technology. Observation parameters include the weight of stover at harvest, the average number of tubers per plant, and tuber yield of tons/ha. Data were analyzed using the T-test The results of the analysis showed that the weight of shallots at harvest was 3.4g heavier and real eda by way of farmers (1.48g). The number of tubers per plant was not affected by irrigation techniques, but the weight of the shallot bulbs increased by 48.9% and the yield per ha increased by 48.40% from the rainfall that occurred during the study.
