Abstract

Sengon wood sawdust compost that is given a bioactivator can be a solution for the low production of shallots in Indonesia. By doing this research, it is hoped that information can be obtained regarding the effect of compost, chemical fertilizer manufacturers and the effect of the combination treatment of the two fertilizers on the growth, yield, and quality of shallots. The research method used was RAKL with 2 factors, namely the application of sawn compost of sengon wood (P2) Monodon [0,2 ml/l]; (P5) Monodon+Stardec [0.2 ml/l+3.8 g/l]; (P6) EM4+Monodon+Stardec [36 ml/l+0.2 ml/l+3.8 g/l]; and application of doses of Urea, ZA, SP36 and KCl (T0) 150, 150, 120, 150 kg/ha, respectively; (T1) 359, 359, 511, 115 kg/ha; (T2) 269, 269, 383, 86 kg/ha; (T3) 179, 179, 255, 57 kg/ha. The results of the study explained that the variable number of leaves had no significant effect on the treatment of compost, chemical fertilizers or their combination. Plant height and tuber hardness significantly affected the chemical fertilizer treatment (T2), respectively 37.56 cm/plant and 3.82 g/cm2. The weight of dry tubers significantly affected the compost treatment (P5), each of which was 29.42; 17.46; 21.71 and 16.11 g/plant. Observation of the quality of shallot yields, tuber diameter of all treatments included in quality I. tuber moisture content of all treatments did not fall into the quality category. Observation of the results of FTIR analysis, for (P6), (T3) and (P6T3), respectively (274 and 464 ppm), (340 and 575 ppm), (371 and 628 ppm).

Abstract

The aims of the study are to determine the effect of various manufactured chemical fertilizers on the increase of the essential oil content in Tuk-tuk and to determine which treatment is best to increase the essential oil content of this particular variety of shallots. The study used a non-factorial randomized block design with three treatments, and each was repeated nine times. The treatments' dosages were B1: ZA 50kg/ha; Urea 25kg/ha; SP36 250kg/ha and KCl 25kg/ha, B2: ZA 100kg/ha; Urea 50kg/ha; SP36 300kg/ha and KCl 50kg/ha, B3: ZA 150kg/ha; Urea 100kg/ha; SP36 350kg/ha and KCl 100kg/ha. The growth and yield observation variables in this study were the number of leaves (fruit), plant height (cm), leaf area (cm2), tuber diameter (cm), fresh plant weight (g), dry plant weight (g), fresh tuber weight (g), dry tuber weight (g), essential oil content (%). The data obtained were analyzed using the F-test, and then the data showed a significant effect proceeded with the DMRT test at a level of 5%. The results of the F-test on the shallots' observed growth and yield variables were not significantly affected by the treatment of manufactured chemical fertilizer. Meanwhile, B3K5 treatment with B3 dose: ZA 150kg/ha; Urea 100kg/ha; SP36 350kg/ha, and KCl 100kg/ha were the best treatments to increase the essential oil content in the Tuk-tuk variety.
