Karakterisasi Plasma Nutfah Mentimun

AbstactCaharcterization of Cucumis sativus germplasms was done to get the description of plant character for the breeder to use as &ldquo;Working Collection&rdquo; materials which were useful in breeding programme. Characterization was done on 23 accessions of Cucumis sativus germplasm planted at Subang station (100 m asl) during dry season 2003. Twenty seeds of each accession planted in a plot with planting distance of 70 x 40 cm. The description of Cucumis sativus germplasms had been done. Six accessions of Cucumis sativus were selected for Working Collection based on fruits quality and resistance to environmental stresser.AbstrakKarakterisasi plasma nutfah mentimun dilakukan untuk mendapatkan deskripsi sifat untuk dipilih oleh pemulia sebagai bahan &ldquo;koleksi kerja&rdquo; yang dapat dimanfaatkan dalam program pemuliaan. Karakterisasi dilakukan terhadap 23 aksesi plasma nutfah mentimun yang ditanam di Kebun Percobaan Subang (100 m dpl) pada MK 2003, masing-masing aksesi ditanam 20 biji per petak dengan jarak tanam 70 x 40 cm. Deskripsi plasma nutfah mentimun tersebut dibuat untuk dimanfaatkan dalam upaya mendapatkan kultivar unggul baru. Dari hasil karakterisasi terpilih enam aksesi mentimun sebagai koleksi kerja pemulia berdasarkan kualitas buah dan ketahanan terhadap cekaman lingkungan.

Characterization of tomato germplasm on the basis of tomato description was conducted of the Lembang Vegetables Government Research Institute. (1250 m asl), in the dry season 2003. Twenty five accession were observed, each accessions 20 plants were planted per plot with the distance 70 x 50 cm. Plants were fertilizer at the rate of 30 t/ha stable manure and 1000 kg/ha NPK applied two days before planting. Description of those accessions was determined for further use in breeding programme.

Abstract Three treatments were tested with four replications at RCBD, namely cassava monoculture, corn twice under cassava intercropping, and corn with corn monoculture where the second corn was planted 5 days after harvested. Planting distance of cassava in monoculture was 100x100 cm, and in intercropping was 200x50 cm, by which corn was planted in 50x30 cm, 1 seed per hole. All plots received dairy cattle manure 5 t ha-1. Fertilizer applied for cassava was Urea 100 kg ha−1, Ponska 200 kg ha−1 and KCl 100 kg ha−1 split into two applications two weeks after cassava planting, then when first of corn was harvested. Corn fertilization was Ponska 150 kg ha−1 + Urea 100 kg ha−1 every 3 months and split into two applications: 1 week and 4 weeks after corn was planted. Cassava and twice corn fertilization was Urea 300 kg ha−1 + Phonska 400 kg ha−1 + KCl 100 kg ha−1. Results showed that cassava monoculture can be improved by inserting of twice corn in between rows. Under sole cropping cassava, the B/C ratio was the highest 1.61, however with incorporating twice of corn the B/C ratio was 1.58. Intercropping cassava and twice of corn resulted in the Land Equivalent Ratio 2.146. By intercropping cassava with corn twice at the end of dry season, there was an opportunity to find corn biomass for dairy cattle. Under intercropping, cassava was able to produce 21.5 t ha−1 of fresh roots, while first and second of corn produced fresh biomass of 34 t ha−1 and 28 t ha−1 respectively.
