Abstract

The Study was aimed to observe optimal planting distance and potassium fertilizer to produce shallot in palu valley. The factorial Randomized Block Design (RAK) with two treatments was used. The first factor was the dosage of K fertilizer namelywithout KCl (control), 20 g KCl/m2, and 30 g KCl m-2. The second factor was planting distance with 3 standards: 15 x 10 cm, 15 x 15 cm, and 15 x 20 cm. The result of the study showed that the application of potassium fertilizer gave significant effects on plant height, number of leaves, number of tillers, number of tuber per clump, tuber weight per clump, and tuber weight per hectare. The highest amounts of plant height, number of tillers, number of tuber per clump, tuber weight per clump, and tuber weight per hectare were affected by the application of 20 g KCl m-2 ; 29.09 cm, 7.40 cloves, 32.22 g, and 11.35 ton ha-1, yet they did not give any significant effect on bulb diameter. On the other hand, planting distance treatment significantly affected plant height in 60 days after planting, number of tillers in 30 days after planting, bulb diameter, and tuber weight per clump, yet it did not give any significant effect on number of leaves, number of tuber per clump, and tuber weight per hectare. The interaction of potassium fertilizer application and planting distance did not give any significant effect on all the observed variables.
