“…A high light intensity causes damage on shade-lover plants, which explains the poor growth performance of Z. zerumbet under 0% shade level. A reduction of the leaf area was also observed in the open field, which may be due to a higher radiation level that damaged the photosynthetic pigment [28]. When a plant's leaf area reduces, photosynthesis will eventually decrease, thus leading to poor rhizome yield.…”

Zingiber zerumbet (L.) Smith, known as Lempoyang in Malaysia, belongs to the family Zingiberaceae. Previous studies on Lempoyang mainly focused on the chemical properties and biological activities of the rhizome extracts of this plant. Despite the tremendous demand for the rhizomes of Z. zerumbet, there is a lack of information on cultivation practices and a scarcity of planting materials. By using the pre-soaked technique, the challenges posed by Z. zerumbet dormancy can be overcome, obtaining good quality and uniform planting material throughout the year. Besides that, it is also crucial to determine the optimum shade level and NPK fertilizer rates to obtain a high yield and good quality rhizomes of Lempoyang. Six concentrations of 6-benzylaminopurine (BAP, 0, 50, 100, 150, 200, and 250 mg/L) and ethephon (0, 150, 300, 450, 600, and 750 mg/L) were tested to evaluate their effects on breaking rhizome dormancy. Three different shade levels (full sun, 30%, and 50% shade levels) and four combinations of Nitrogen (N), phosphorus (P), and potassium (K) (NPK) fertilizer at different rates were evaluated to study their effects on plant growth and yield performance. The results showed that BAP at 100 mg/L and ethephon at 300 mg/L performed better than the other compound concentrations tested in promoting the breaking of bud dormancy. A significant interaction effect was observed between shade levels and NPK fertilizer rates in all the growth parameters examined, except for the number of tillers per plant. Plants grown under 30% shade with NPK 4 produced the highest rhizome fresh weight, dry weight, and yield, but plants grown under 50% shade with NPK 4 showed the highest plant height and number of tillers per plant.

“…Menurut Nagasubramaniam et al (2007) dan Jeyakumar et al (2008) laju fotosintesis berkorelasi positif terhadap akumulasi biomassa. Srikrishnah et al (2012) melaporkan hasil yang sama pada tanaman draceana dimana biomassa meningkat pada perlakuan naungan sampai 70%. Pada penelitian nilam sebelumnya, produksi terna basah pada intensitas cahaya 100% dan 80% tidak berbeda nyata (Rosman et al 2016).…”

ABSTRAKNilam (Pogostemon cablin) merupakan tanaman semak yang dapat tumbuh di tempat ternaungi maupun terbuka. Namun perubahan karakter morfologis dan fisiologis tanaman pada naungan 55% yang mempengaruhi hasil belum diketahui. Penelitian dilaksanakan sejak April sampai September 2015 di Kebun Percobaan Cimanggu, Bogor. Penelitian bertujuan untuk membandingkan perubahan karakter morfologis dan fisiologis tanaman nilam yang mempengaruhi produksi dan mutu minyak nilam yang ditanam di bawah naungan 55% dan tanpa naungan. Penelitian menggunakan Rancangan Acak Kelompok dengan 20 ulangan. Parameter yang diamati adalah morfologi (jumlah daun, luas daun spesifik, tinggi tanaman dan jumlah cabang) dan fisiologi (kandungan air nisbi, jumlah klorofil, laju fotosintesis dan transpirasi), serta produksi terna dan hasil minyak. Data dikumpulkan dari masing-masing 20 sampel tanaman, dianalisis rata-rata dan standard error untuk menguji perbedaan antar perlakuan dan diuji lebih lanjut dengan analisis berganda Spearman untuk mengetahui hubungan antara parameter dengan hasil. Hasil penelitian menunjukkan tanaman nilam yang ditanam di bawah naungan 55% memiliki tinggi 87,05 cm, jumlah daun (576 helai), kandungan klorofil total (0,62 mg g -1 ), luas daun spesifik (191,57 g cm -2 ) dan laju fotosintesis (12,2 μmol CO 2 m -2 s -1 ) lebih tinggi dan berbeda nyata dibandingkan dengan tanaman nilam yang ditanam tanpa naungan.Produksi terna kering 131,9 g tanaman -1 meningkat 300% dibandingkan dengan tanpa naungan, dengan kadar minyak 2,3%.
