A study had been done in MARDI Serdang to investigate the growth and yield response of shallot (Allium ascalonicum var. Sanren F1) in various planting distance and fertilizer rate. The objective of this study is to determine the suitable planting distance and optimum rate of NPK 15:15:15 fertilizer based on growth and yield of shallot in mineral soils. The experiment was done in a plot, consist of sandy clay soil type at the period of January to March 2022. The experimental plot was laid out in Split Plot Design, with planting distance as main plot while fertilizer rate as sub plot in three replications. The planting distance treatments were J1: 15cm x 15cm (control), J2: 15cm x 10cm and J3: 10cm x 10cm. The fertilizer rate use was N: 300kg/ha, N2:400kg/ha, N3:500kg/ha and N4: 600kg/ha (control). Overall, the result of this study showed interaction between planting distance and fertilizer rate on plant height, bulb diameter and fresh weight. J1 and J2 on N2, N3 and N4 were significantly affected the plant height, bulb diameter and fresh weight compare with other treatments. However, no interaction was found on leaf numbers, bulb numbers and marketable yield. This study concluded that the application of 600kg/ha NPK 15:15:15 fertilizer with 15cm (between row) x 15cm (in the row) planting distance can be used for optimum growth and yield of Sanren F1 variety shallot production in mineral soils.

Abstract

A study had been done in MARDI Serdang to investigate the growth and yield response of shallot (Allium ascalonicum var. Sanren F1) in various planting distance and fertilizer rate. The objective of this study is to determine the suitable planting distance and optimum rate of NPK 15:15:15 fertilizer based on growth and yield of shallot in mineral soils. The experiment was done in a plot, consist of sandy clay soil type at the period of January to March 2022. The experimental plot was laid out in Split Plot Design, with planting distance as main plot while fertilizer rate as sub plot in three replications. The planting distance treatments were J1: 15cm x 15cm (control), J2: 15cm x 10cm and J3: 10cm x 10cm. The fertilizer rate use was N: 300kg/ha, N2:400kg/ha, N3:500kg/ha and N4: 600kg/ha (control). Overall, the result of this study showed interaction between planting distance and fertilizer rate on plant height, bulb diameter and fresh weight. J1 and J2 on N2, N3 and N4 were significantly affected the plant height, bulb diameter and fresh weight compare with other treatments. However, no interaction was found on leaf numbers, bulb numbers and marketable yield. This study concluded that the application of 600kg/ha NPK 15:15:15 fertilizer with 15cm (between row) x 15cm (in the row) planting distance can be used for optimum growth and yield of Sanren F1 variety shallot production in mineral soils.
