“…On the other hand, shade can inhibit the rate of strong winds which can affect the reproduction process of mace. According to [7] nutmeg plants are very sensitive to strong winds, therefore nutmeg plantations require protection or windbreaks. Winds that are too strong not only cause the pollination of flowers to be disrupted but also cause the flowers, fruit, and plant shoots to fall.…”

Smallholder plantations are agricultural areas in North Sulawesi (about 50-60%) with an area of about 413,000 ha, of which more than 97% of the managers are farmers and generally located in one area. This paper aims to optimize land use for nutmeg by using banana plants as shade in the nutmeg growth phase as an acceleration of farming development in the farmers plantation area of North Sulawesi. The research was carried out in Kauditan District, North Minahasa Regency, North Sulawesi Province from March to December 2021. The area of the research object is 1 ha of nutmeg plants with 3 local banana varieties (Goroho, Cepatu, Ambon) planted as shade plants. Growth observations were made on nutmeg and banana plants. The results showed that the use of banana plants as shade plants gave a good response to the growth of nutmeg as the main crop. Farmers in plantation areas get significant added value from banana plants when nutmeg plants are in their infancy. The findings from this study are still very limited, so more in-depth further research is needed.

“…Jintan banyak diimpor dari India dan Mesir serta negara Timur Tengah lainnya, total impor sebanyak 510,003 kg per tahun senilai US$364.394,00 (Wahyuni, 2009). Produk jintan hitam banyak dijual dalam bentuk serbuk dan minyak yang dikemas dalam kapsul dan dikenal dengan nama "Habbatussauda" (Suryadi, 2014).…”

“…Indonesia merupakan negara tropika yang memiliki suhu, kelembaban, dan curah hujan lebih tinggi serta tingkat kemasaman tanah yang lebih rendah dibandingkan daerah asal jintan hitam. Perbedaan lingkungan tumbuh tersebut dapat mempengaruhi respon tanaman dalam menyerap unsur hara (Suryadi, 2014).…”

“…Agar diperoleh hasil yang optimal, maka perlu diketahui dosis pupuk yang tepat sesuai dengan kebutuhan tanaman. Hasil penelitian Suryadi (2014) menunjukkan bahwa pemupukan N dengan dosis 120 kg ha -1 + 157 kg ha -1 P2O5 menghasilkan produksi biji, kadar thymoquinone, dan produksi thymoquinone tertinggi, masing-masing 363.05 kg ha -1 , 0.0625% dan 298.4 g ha -1 . Yimam et al (2015) juga membuktikan peran N untuk meningkatkan produksi jintan di Etiopia.…”

Tanaman jintan hitam merupakan tanaman obat yang berpotensi untuk dikembangkan di Indonesia. Tanaman ini merupakan tanaman introduksi sehingga adaptasi dan teknik budidayanya masih terbatas diketahui di Indonesia. Penelitian ini bertujuan untuk menentukan dosis pupuk N dan K yang dapat meningkatkan pertumbuhan dan produksi biji jintan hitam yang ditanam di daerah tropika. Penelitian dilakukan pada bulan Juni hingga November 2016 di Kebun Percobaan IPB, Pasir Sarongge, Cianjur, Jawa Barat dengan ketinggian tempat kurang lebih 1,117 m dpl. Percobaan dilakukan dalam rancangan kelompok lengkap teracak dua faktor dengan tiga ulangan. Faktor pertama yaitu perlakuan empat taraf dosis pupuk nitrogen (0, 120, 180, dan 240 kg N ha-1). Faktor kedua yaitu empat taraf dosis pupuk kalium (0, 30, 60, dan 90 kg K2O ha-1). Pupuk fosfor digunakan sebagai pupuk dasar dengan dosis 157 kg P2O5 ha-1. Data hasil pengamatan dianalisis dengan Uji F dengan uji lanjut Duncan Multiple Range Test (DMRT) pada taraf α=5%. Hasil penelitian menunjukkan bahwa perlakuan pupuk N berpengaruh nyata terhadap panjang kapsul, jumlah kapsul berisi per tanaman, bobot biji per tanaman dan produktivitas, namun tidak berpengaruh terhadap pertumbuhan tanaman jintan hitam. Perlakuan pupuk K tidak berpengaruh nyata terhadap pertumbuhan dan produksi jintan hitam. Interaksi perlakuan pupuk N dan K tidak berpengaruh nyata terhadap pertumbuhan dan produksi jintan hitam. Kata kunci: black seed, kapsul, tanaman obat, tropika

“…Hal ini karena media yang digunakan sudah mengandung nitrogen dengan kriteria tinggi (0.65%) yang mampu mendukung perkembangan tanaman. Berbeda dengan penelitian Suryadi et al (2017) kadar N-total pada kriteria rendah yaitu 0.2% sehingga pemupukan N mampu meningkatkan semua komponen hasil pada tanaman jintan hitam.…”

ABSTRACT Black cumin (Nigella sativa L.) is an introduced medicinal plant therefore requires investigations to establish recommended cultivation procedure in tropical areas. Black cumin seeds contain a various bioactive compounds not only for culinary but also for medicinal purposes. This study was conducted to investigate the effect of nitrogen rates and shade levels on growth of Black cumin. The activity was carried out in Pasir Sarongge experimental station, Cianjur, West Java (1,117 masl). The research was arranged in nested design with three replications. Nitrogen rates was nested within shading levels. The shading levels consist of 0%, 25%, 50%, and 75% which resulted in light intensity of 27,800, 17,400, 11,900, and 1,600 lux respectively. The Nitrogen rates consisted 0, 60, 120, and 180 kg ha-1. The results showed that shading up to 50% did not affect plant growth and did not reduce seed production. However, shading up to 75% prolong the vegetative period, decreased leaf thickness and plant dry weight. The higher the shading level up to 50%, the higher the plant height, leaf area, number of leaves and number of flower, but not number of branche. Nitrogen fertilizer 60 kg ha-1 increased number of blooming flower and number of capsule set. Keywords: flowering, high altitude, leaf, tropic
