Peningkatan Mutu Bunga dan Produktivitas Dua Kultivar Sedap Malam dengan Pemupukan N, P, dan K

A Wasito, R Tedjasarwana

Abstract


Penelitian bertujuan mengetahui tanggap kultivar sedap malam terhadap pemberian beberapa kombinasi dosis pupuk dalam rangka peningkatan produktivitas dan mutu bunga. Penelitian dilaksanakan di Cianjur dari bulan September 1998 sampai dengan bulan Juli 1999. Penelitian menggunakan rancangan acak kelompok pola faktorial dengan tiga ulangan.  Dua kultivar, yaitu kultivar berbunga tunggal dan berbunga ganda sebagai  faktor pertama  dan tujuh kombinasi dosis pupuk inorganik (N, P2O5, dan K2O) sebagai faktor kedua. Didapatkan bahwa keragaan tumbuh dan hasil bunga  kultivar bunga berpetal  ganda  lebih adaptif dibandingkan dengan kultivar bunga berpetal tunggal. Kombinasi dosis pupuk inorganik dengan N tertinggi (40 g/m2/tahun), menampakkan keragaan yang paling baik dan berbeda nyata dengan beberapa kombinasi di bawahnya sepanjang diimbangi dengan  jumlah unsur P dan K.

ABSTRACT. The objective of this experiment was to evaluate response of two cultivars P. tuberose treated with several inorganic fertilizer dosages application. Experiment was conducted in Cianjur from September 1998 until July 1999. A factorial randomized block design with three replications was used in this experiment. The first factor consisted of two cultivars meanwhile the second factor com- prised of seven dosages inorganic fertilizers ( N, P2O5, and K2O) compositions. The results indicated that  the double petals cultivar was significantly more adaptive compared to those of single petal cultivar.  Dosage of   N inorganic fertilizer applications up to 40 g/m2/year gave significantly different  compared to that below  dosages.
