Tanaman jahe (Zinqiber officinale Rosc) mendapat perhatian karena meningkatnya permintaan ekspor. Tahun 1985 tercatat volume ekspor sebesar 11176.8 ton, dan pada tahun 1991 volume ekspor mencapai 46299.to2n (BPEN,1992). Meningkatkan intensitas pemanfaatan lahan, tidak saja berperan dalam upaya peningkatan produksi jahe, tetapi juga sangat berarti bagi upaya menjamin penyediaan produk tanaman jahe secara teratur dan berkesinambunqan, khususnya pada keadaan lahan terbatas. Masalah yanq dihadapi dalam upaya meningkatkan intensitas pemanfaatan lahan dengan penerapan pola tanam beruntun, yaitu kehilanqan hasil pertanaman kedua. Faktor-faktor penyebab kehilangan hasil dalam pola tanam beruntun antara lain berupa pengaruh fitotoksik dari pertanaman yang mendahului (alelopati). People interest in ginger (Zingiber officinaie Rose) has raised since the demand for ginger export
increased. In 1985 the export of ginger was 11176.8 tons, and in 1991 was 46299.2 tons (BPEN,
1992). Increasing the intensity of land utilization is important not on1y for increasing the
ginger production, but also to ensure the continuity of ginger supply, especially in the limited
planting area. The problem faced in increasing land utilization intensity by continuous cropping
pattern is the yield 1oss of the second crop. The yield loss in the continuous cropping can be
caused by several factors, among others is the fitotoxic effect of the previous crop (allelopathy).
The objective of this research is to study the effect of allelopathy on the yield loss of ginger as
the second
crop in the ginger continuous cropping pattern.
