Abstract

Percobaan dilaksanakan di lahan petani Kabupaten Lebak, Banten, mulai bulan Juli sampai Oktober 2001.  Jenis tanah masam adalah ultisols yang mempunyai ketersediaan P rendah dan sifat fisik jelek. Tujuan percobaan adalah mempelajari pengaruh inokulasi cendawan mikoriza arbuskula, penyediaan bahan organik dari pupuk kandang domba dan dosis fosfat alam (P) terhadap pertumbuhan, serapan P, dan hasil mentimun. Perlakuan terdiri atas 3 dosis fosfat alam, pupuk kandang domba, dan inokulasi mikoriza. Kombinasi perlakuan seluruhnya ada 12 dengan 3 ulangan yang disusun dalam rancangan acak kelompok faktorial. Hasil percobaan menunjukkan bahwa pemberian pupuk kandang domba meningkatkan efisiensi penggunaan fosfat alam, pertumbuhan, bobot buah, dan infeksi akar.  Pengaruh mikoriza tampak jelas jika disertai penggunaan pupuk kandang domba.  Tanpa  pupuk kandang domba maupun tanpa mikoriza, dosis P yang dibutuhkan untuk menghasilkan buah mentimun adalah 200 kg P2O5 /ha, sedangkan dengan pupuk kandang domba maupun dengan mikoriza dosis P yang dibutuhkan untuk menghasilkan buah mentimun yang sama hanya 100 kg  P2O5 /ha.  Tanpa pupuk kandang, mikoriza, dan pupuk P (kontrol), tanaman tidak menghasilkan buah mentimun. Teknologi yang diperoleh dari penelitian ini sangat berguna untuk pengembangan tanaman sayuran pada tanah-tanah masam atau lahan marginal seperti ultisols.The experiment was conducted at the farmer field in Lebak Distric of Banten Province, from July until October 2001. The soil type was ultisols with low P availability and poor physical property. The objectives of this experiment was to study the effect of application of rock phosphate, sheep manure, and arbuscular mycorrhiza fungi inoculation on the growth, P uptake, and yield of cucumber in acid soil.  The treatments consisted of three rates of rock phosphate, 2 rates of sheep manure and 2 rates of mycorrhiza inoculation. All treatment combinations were arranged in a factorial randomized block design with 3 replications. The results showed that sheep manure application increased the efficiency of rock phosphate application, growth, yield of cucumber, and root infection. The effect of mycorrhiza inoculation was distinct when accompanied with sheep manure supply. Without sheep manure supply and without mycorrhiza inoculation, 200 kg P2O5/ha of rock phosphate was needed to produce cucumber, while sheep manure supply and mycorrhiza inoculation, only 100 kg P2O5/ha of rock phosphate was needed to produce equivalence cucumber fruit. Without rock phosphate application, sheep manure supply, and mycorrhiza inoculation (control), the plant did not produce any cucumber fruit. The results of the experiment can be usefull for developing vegetables cultivation on acid soils or marginal land such as ultisols.

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).

Abstract

ABSTRAK. Penelitian dilakukan di lahan petani di daerah Kabupaten Lebak, Banten. Jenis tanah Ultisol dengankandungan P rendah dan karakteristik fisik yang buruk. Tujuan percobaan adalah mempelajari pengaruh inokulasicendawan mikoriza arbuskula, penyediaan bahan organik dari pupuk kandang domba, dan dosis fosfat alam terhadapserapan P oleh tanaman, hasil mentimun, dan kandungan hara tanah masam Ultisols. Penelitian dilaksanakan daribulan Juli sampai Oktober 2004. Perlakuan terdiri atas 3 dosis fosfat alam, pupuk kandang domba, dan inokulasimikoriza. Kombinasi perlakuan seluruhnya ada 12 dengan 3 ulangan yang disusun dalam rancangan acak kelompokfaktorial. Hasil percobaan menunjukkan bahwa pemberian pupuk kandang domba meningkatkan efisiensi penggunaanfosfat alam, bobot buah, dan serapan hara. Interaksi antara mikoriza dengan pupuk P dan bahan organik denganpupuk P berpengaruh nyata terhadap serapan P. Tanpa pupuk kandang domba maupun tanpa mikoriza, dosis P yangdibutuhkan untuk menghasilkan buah mentimun adalah 200 kg P2O5 /ha, sedangkan dengan pupuk kandang dombamaupun dengan mikoriza dosis P yang dibutuhkan untuk menghasilkan buah mentimun yang sama hanya 100 kgP2O5 /ha dan kombinasi perlakuan tersebut meningkatkan ketersediaan P tanah. Inokulasi mikoriza tanpa bahanorganik menurunkan pH tanah. Penggunaan fosfat alam pada dosis tinggi dengan adanya bahan organik meningkatkansenyawa Ca-P pada tanah Ultisols. Teknologi yang diperoleh dari penelitian ini sangat berguna untuk pengembangantanaman sayuran pada tanah-tanah masam atau lahan marginal seperti Ultisols.ABSTRACT. Rosliani, R. , Y. Hilman, and N. Sumarni. 2009. The Effect of Rock Phosphate Fertilizer and SheepManure Application, and Arbuscular Mycorrhizae Fungi Inoculation on the Growth and Yield of Cucumberin Ultisol Acid Soil. The experiment was conducted at the farmer field in Lebak District of Banten Province. Thesoil was Ultisols with low available P and poor physical property. The objectives of this experiment was to study theeffect of rock phosphate and sheep manure application, and arbuscular mycorrhizae fungi inoculation on the growth,P uptake, and yield of cucumber in acid soil. The treatments consisted of 3 levels of rock phosphate, 2 levels of sheepmanure, and 2 levels of mycorrhizae inoculation. All treatment combinations were arranged in factorial randomizedblock design with 3 replications. The results showed that sheep manure supply could increased the efficiency ofrock phosphate application, growth, yield of cucumber, and nutrient uptake. The effect of mycorrhizae inoculationwas more clear when accompanied by sheep manure supply. Interaction of sheep manure and rock phosphate ormycorrhizae inoculation and rock phosphate significantly increased P uptake. Without sheep manure supply andwithout mycorrhizae inoculation, 200 kg P2O5/ha of rock phosphate was needed compare with sheep manure supplyand mycorrhizae inoculation, which only required 100 kg P2O5/ha of rock phosphate to reach the same productivity ofcucumber fruit, and these treatment combination P availability were also increased. Mycorrhizae inoculation withoutsheep manure could decrease the soil pH. Rock phosphate at high dosage with sheep manure could increase Ca-Pon Ultisols acid soil. The results of the experiment could be benefit for the development of vegetables on acid soilsor marginal land such as Ultisols.
