Abstract

Formula pupuk yang dipergunakan pada tanaman mawar di Indonesia perlu dikembangkan. Tujuanpenelitian untuk mengetahui formula pupuk yang sesuai bagi mawar potong pada beberapa jarak tanaman. Percobaandilaksanakan di dalam Rumah Plastik Kebun Percobaan Segunung, Balai Penelitian Tanaman Hias, di Desa CiherangCipanas, Pacet, Cianjur, Jawa Barat pada ketinggian 1.100 m dpl. pada bulan September 2003 - Januari 2004. Percobaanmenggunakan rancangan petak terpisah dengan 3 ulangan. Petak utama adalah formula pupuk yaitu komersial (JORO),Cipanas A1, dan Cipanas A2. Anak petak terdiri dari jarak tanam 30x30 cm, 30x20 cm, 30x15 cm, 40x20 cm, dan40x15 cm. Hasil percobaan menunjukkan bahwa panjang tangkai bunga tertinggi (63,33 cm) dan produksi bungatertinggi (46,31 tangkai/petak) diperoleh pada jarak tanam rapat (30x15 cm). Jumlah petal bunga tertinggi (44,27petal/kuntum) diperoleh pada jarak tanam terlonggar (30x30 cm) yang sama dengan jarak tanam terapat (30x15 cm)sebesar 40,53 petal/kuntum. Lama kesegaran bunga tertinggi (4,77 hari) diperoleh pada jarak tanam 40x20 cm yangsama dengan jarak tanam lainnya, kecuali pada jarak tanam terlonggar (30x30 cm) lama kesegaran bunganya terendah(4,33 hari). Formula pupuk komersial, Cipanas A1 dan Cipanas A2 yang diuji menunjukkan hasil yang tidak berbedanyata. Oleh karena itu formula pupuk Cipanas A1 dan Cipanas A2 dapat sebagai pengganti formula pupuk komersial.Hasil penelitian ini dapat dipergunakan pengusaha dan petani bunga mawar potong untuk meramu pupuk–pupukyang diteliti secara tunggal menjadi 1 formula pupuk yang lengkapABSTRACT. Tejasarwana R. and I.B. Rahardjo. 2009. The Effect of Fertilizer Formulae and Plant Spacing onthe Yield and Quality of Rose Cut Flower. Fertilizer formulae for rose cultivation in Indonesia need to be developed.The objective of the experiment was to find out appropriate fertilizer formulae and plant spacing for rose cut flower.The experiment was conducted in Plastichouse at Segunung Field Trial of Indonesian Ornamental Crops ResearchInstitute, Cianjur, West Java (elevation 1,100 m asl.) from September 2003 to January 2004. Split-plot design with3 replications was used. The main plot was fertilizer formulae, i.e commercial (JORO), Cipanas A1, and Cipanas A2.While the subplot was plant spacing, i.e. 30x30 cm, 30x20 cm, 30x15 cm, 40x20 cm, and 40x15 cm. Results of theexperiment showed that the longest flower stalk (63.33 cm) and the highest flower production (46.31 stalks/plot)were obtained from plant spacing 30 x15 cm. The highest petal number/flower (44.27 petals/flower) were obtainedfrom plant spacing 30x30 cm that was similar with plant spacing 30x15 cm (40.53 petals/flower). The longest flowervaselife (4.77 days) was obtained from plant spacing 40x20 cm that was same with other treatments, except on spacingof 30x30 cm of having flower vase life the lowest (4.33 days). Fertilizer formulae of commercial, Cipanas A1, andCipanas A2 showed no significant different. Therefore fertilizer formulae of Cipanas A1 and Cipanas A2 could be usedas substitution for commercial fertilizer formulae. This result can be used by businessman and farmer to formulatethe fertilizer that have been studied singly to become a complete fertilizer formulae

Abstract

Krisan merupakan salah satu tanaman hias penting dalam industri florikultura di Indonesia. Dalam budidayanya, pertumbuhan dan produktivitas krisan sangat dipengaruhi oleh pemberian pupuk yang sesuai dan optimal. Pupuk N, P, dan K sering diaplikasikan tanpa memperhatikan cara aplikasi dan takaran yang tepat. Penelitian bertujuan untuk mengetahui cara aplikasi dan takaran pupuk terhadap pertumbuhan dan produksi bunga krisan. Penelitian dilakukan di Kebun Percobaaan  Balai Penelitian Tanaman Hias Segunung 1.100 m dpl. dari bulan Januari sampai dengan Desember 2007. Bahan tanaman yang digunakan adalah krisan varietas Puspita Nusantara. Pupuk yang digunakan yaitu Urea, KNO3, dan SP-36. Percobaan menggunakan rancangan petak terpisah dengan tiga ulangan. Petak utama ialah cara aplikasi pupuk butiran dan fertigasi. Sebagai anak petak ialah takaran pupuk, yaitu tanpa pupuk, ½ takaran anjuran, 1 takaran anjuran, dan 1½ takaran anjuran. Hasil percobaan menunjukkan bahwa pemberian pupuk dengan cara ditabur dan fertigasi memberikan pengaruh yang sama, sedangkan takaran pupuk 1½ takaran anjuran menunjukkan pertumbuhan vegetatif dan jumlah bunga lebih tinggi dibandingkan perlakuan lainnya (diameter batang terbesar 5,90 mm, panjang daun 8,41 cm, jumlah daun/tanaman tertinggi 37,5 helai, dan 10,5 kuntum/tanaman). Chrysanthemum is one of important ornamental crops on the floriculture industry in Indonesia. In Chrysanthemum cultivation, growth and productivity of it are significantly affected by application of appropriate fertilizer in optimal dosage. N, P, and K fertilizer were frequently applied without taking into consideration on its application method and appropriate dosage. The objective of this study was to determine effect of application method and dosage of fertilizer on plant growth and production of Chrysanthemum. The experiment was carried out at Segunung Field Experiment Station of Indonesian Ornamental Crops Research Institute 1,100 m asl. from January to December 2007. The material used in the experiment was Puspita Nusantara varieties. The fertilizer utilized in the study were Urea, KNO3, and SP-36. The treatments were arranged in split plot design with three replications. The main plot was application method of fertilizer i.e. spreading and fertigation. The subplot was without fertilizer, ½ recommended suggestion dosage, 1 recommended suggestion dosage, and 1½ recommended suggestion dosage. Results showed that application of fertilizer both spreading and fertigation gave the same effect on growth and production of Chrysanthemum. Fertilizer dosage at 1½ recommended suggestion gave higher effect on vegetative plant growth and number of flower than those others (highest stem diameter 5.90 mm, highest leaf length 8.41 cm, highest leaf number/plant 37.5 leaves, and 10.5 flowers/plant).
