PENGARUH BAHAN DAN DOSIS KOMPOS CAIR TERHADAP PERTUMBUHAN SELADA (Lactuca sativa sp.) (The Effect Of Material And Dosages Of Liquid Organic Fertilizers On Lettuce (Lactuca sativa Sp.) Growth)
Full text linkThe aim of this research was to examine the effect of different material and dosages of liquid organic fertilizer on growth and yield of lettuce. The experiment was conducted at Agriculture farm, Jambi University. The laboratory analysis of soil and plant was conducted at Agriculture Laboratory and material of organic fertilizers in BALITRO, Bogor. Research design used factorial, arranged with randomized complete block designed. The treatment are Factor I material of organic compost liquid, control (p0), Imperata cylindrica (p1), Cromolaena odorata (p2) and Leucena lecochepala (p3), and the second factor are dosage, control (d0), 5 ml (d1), 10 ml (d2) and 15 ml (d3). Result showed that there was interaction affect between liquid compost material and dosage on growth parameter, number of leaves, leaf area, plant height, fresh weight dan plant yield. The trend of growth parameter indicated that compost material Cromolaena odorata at dosage 15 ml showed the highest. The same result was achieved at lettuce yield. However, in this research the optimum combination of liquid compost material and dosage was not yet attainable.Key words: Fertilizers, lettuce, cromolaena, leucena, imperat
KARAKTER KUALITATIF DAN HUBUNGAN KEKERABATAN BEBERAPA GENOTIPE CABAI (Capsicum annuum L.) (The Qualitative Characterization and The Genetic Relationship of Chillies Genotypes (Capsicum annuum L.))
Full text linkThe research purposed to find out the agronomic characteristics of 10 chillies genotypes and relationship between genotypes. The experiments was conducted at Experiment Plantation at Leuwikopo, Bogor Agricultural University, Darmaga, from March to August 2011. The research showed that there is a significant differences between genotypes in the qualitative character. The genetic relationship of all genotypes tested and the qualitative character looks at the form of rods, the number of flowers by axil, the crown form of flowers, the colors of ripes fruits, the beginning of fruits form and the tip form of fruits.Keywords : Chillies, characterization, qualitativ
PERTUMBUHAN KELAPA SAWIT (Elais guineensis Jaqc. ) DI PEMBIBITAN UTAMA DENGAN PERBEDAAN KOMBINASI PUPUK CAIR NUTRIFARM DAN NPKMg (The Seedling Growth Of Oil Palm (Elais guineensis Jaqc) In Nursery With Different Liquid Fertilizers Nutrifarm And NPKMg Comb
Full text linkThis experiment was conducted to determine the growth of oil palm seedlings to the provision of a complementary combination liquid fertilizer and manure Nutrifarm AG and NPKMg recommendations. This study was conducted at Agriculture Farm Faculty of Agriculture, University of Jambi. This research arranged with Randomized Block Design (RBD) with 6 treatment. Without liquid fertilizer supplement Nutrifarm AG 5 ml.L-1 with 100% NPKMg fertilizer recommendations (control), liquid fertilizer supplement Nutrifarm AG 5 ml.L-1 with no NPKMg, Nutrifarm AG 5 ml.L-1 with 25% water NPKMg, Nutrifarm AG 5 ml.L-1 with 50% water NPKMg Nutrifarm AG 5 ml. L-1 with a 75% water NPKMg, Nutrifarm AG 5 ml.L-1 with 100% water NPKMg. Parameter variables number of leaves, total leaf area, seed diameter, plant dry weight, root dry weight. The data were statistically analyzed and followed by Duncan Multiple Test A (DNMRT) at the level of 5%. Results showed combination liquid fertilizer and manure Nutrifarm AG NPKMg recommendation responds to the high seedling growth, total leaf area and diameter of the seed. And efficient use good combination is the provision of a complementary combination liquid fertilizer Nutrifarm AG 5 ml.L-1 water with 25% fertilizer NPKMg recommendation on oil palm seedlings in the main nursery.Key words : Oil Palm, nutrifar
PENGARUH NAUNGAN TERHADAP KANDUNGAN NITROGEN DAN PROTEIN DAUN SERTA PERTUMBUHAN DAN HASIL TANAMAN KEDELAI (The Effect of Shading to Nitrogen and Protein Contents, The Growth and Yield of Soybean Plants)
Full text linkOne way to improve the productivity of soybean grown as an intercropping plant in the standing area is to develop soybean varieties that are tolerant to shade. This experiment aimed to discover the physiological characteristics in soybean varieties that are tolerant to shade.The results showed that the significant physiological characteristics that determine the level of the soybean tolerance to shade are nitrogen and protein contents.The increasing of nitrogen and protein contents was higher in the tolerant varieties than those of sensitive varieties. Shade treatments affected seed weight. The soybean yield on the 50% shade decreased by 23.11% in the tolerant varieties, and about 27.63% decreased in the sensitive varieties. The yield decrease was lower in tolerant varieties compared to the sensitive varieties. This result was supported by the lower reduction in empty pods.Mechanism of tolerance to shade on soybean plant is characterized by the increase of nitrogen and protein contents. In addition, higher yields on tolerant varieties supported by high pods contain and low empty pods.Key words: Soybean, nitrogen and protein contents
POTENSI SUMBERDAYA LAHAN DI DAS BATANG BUNGO UNTUK PENGEMBANGAN SAYURAN (Land Resources Potency at Batang Bungo Watershed for Vegetables Development)
Full text linkThe aim of this research is to identify watershed land characteristic at Batang Bungo and to analyze land suitability for developing commodity vegetables that were dominantly utilized by the local farmer. It is found that there are 17 land units in Batang Bungo watershed, that used to be basic data to determine sample. The research showed that rubber was the main crop and green vegetables as intercropping plant. The green vegetables were planted dominantly pepper, string beans, and eggplant. These plants were cropped among young rubber plants. The land suitability analysis showed about 55790.2 ha (74,06%) of watershed wide were suitable, the rest was not suitable that by the caused by erosion hazard.
