Abstract

Pemanfaatan Azotobacter dan Azospirillum sebagai mikroba fiksasi N2 dapat menjadi solusi dalam mengurangi penggunaan pupuk N anorganik. Inokulasi mikroba fiksasi N2 tersebut memerlukan isolat yang unggul dalam fiksasi N2 dan viabilitasnya tinggi. Sebuah percobaan penjaringan Azotobacter sp dan Azospirillum sp untuk mendapatkan isolat yang unggul dalam menambat N2 dan  tinggi viabilitasnya pada lahan sawah telah dilakukan di Laboratorium Biologi dan Bioteknologi tanah, Fakultas Pertanian, Universitas Padjadjaran. Isolat diambil dari rizosfir dan padi akar di Sukatani dan Karangbahagia - Bekasi, Rengsdengklok - Karawang, Jatinangor - Sumedang  dan Ciparay - Bandung. Hasil penelitian didapat isolat bakteri yang unggul dalam fiksasi N2 dan viabilitasnya yaitu Azotobacter chroococcum dari rizosfir padi sawah varietas ciherang di Rengasdengklok-Karawang dan Azospirillum irakense dari akar padi sawah varietas ciherang di Ciparay-Bandung. Kata kunci : Azospirillum sp, Azotobacter sp, pupuk hayati, penambat N, sawah

Abstract

A research to study the effect of Azotobacter sp., VAM, and nitrogen fertilizer on Azotobacter sp. density, root infections degree, and soil available N and P was conducted in green house of Fakultas Pertanian, Universitas Padjadjaran at Jatinangor and Soil and Plant Laboratory of Balitsa at Lembang from December 1996 to June 1997 Result of the experiment showed that effect of increased of nitrogen fertilizer dosage on Azotobacter sp. density, soil available N-NO3 and P was depend on applied microbial inoculants. Effect of increased of nitrogen fertilizer dosage on root infections degree* soil available N-NH4 was not depend on applied microbial inoculants. Inoculations MVA was increased root infections degree of tomato, whatsoever nitrogen fertilzer dosage was applied

Abstract

Sulfitr is a secondary plant nutrients to make the amino acids cystine, cysteine and methionine and is part of biotin, thiamine, co-enzyme A and glutationin in plants. Suljur also Junctions as an activator, cofactor or regulator of enzymes and plays a role in plant physiological processes and the formation of chlorophyll. Plants take the sulfitr in the form of SO4 2 anion derived from organic matter, soil minerals and fertilizer. The use of high analysis fertilizer resulted in the emergence of sulfur deficiency symptoms in various agricultural areas. Therefore, the provision of fertilizer sulfitr or sulfitr fertilizer carrier needs to be done to correct it.

Abstract

Seed qualify is one that determines the productivity of soybean. Quality seeds obtained through a series of seed technology activities starting from seed production, seed processing, seed testing, certification of seeds to seed storage. Storage of seeds is one of the soy harvest handling of the whole technology is important to maintain seed quality. The main objective of seed storage is to maintain the viability of the seeds along as possible and to maintain the fsiologis quality of seeds during the period storage by inhibiting the deterioration speed of the seed. Factors that influence the viability of seeds during storage is divided into internal and external factors. Internal factors include genetic trait, the power to grow and Vigor, skin conditions and initial seed moisture content. External factors such as packaging of seeds, gas composition, temperature and humidity save space.

Abstract

The forms of nitrogen can use by plant are nitrate and amonia, but in the world content of them are limited. Form of nitrogen which big content in the world is dinitrogen (N,), this form is not use by plant without transformation to be N03‘ or NH/ . To be use dinitrogen is needed action of fixing nitrogen microorganism or fertilizers fabrications. The nitrogen fixing proccss by microorganism was influenced by ecological factor, adequate of nutrition and energy, and genetic of microorganism it self. The ecological factor which influenced of nitrogen fixing by microorganism are N;. CO,, O,, RH, pH, temperature, and existing other microorganism. Energy and nutrition which needed by fixing microorganism are C-organic, Mo. Co, Fc, P, Ca. Na, and several of vitamins.

Abstract

Perluasan areal pertanian akibat dari pertambahan penduduk mengarah pada tanah-tanah marjinal termasuk tanah gambut baik pasang surut maupun pedalaman. Perkembangan pertanian pada lahan gambut menghadapi berbagai kendala yang berkaitan dengan sifat tanah gambut. Kendala tersebut berupa kendala fisik, kimia dan pengelolaan air. Secara umum lahan gambut mempunyai sifat fisik dan kimia yang tidak mendukung untuk pertumbuhan tanaman yang optimum. Untuk mengatasi masalah dan kendala yang terdapat pada lahan gambut dapat dilakukan berbagai upaya rehabilitasi. Upaya tersebut adalah pemberian bahan pembenah tanah (amelioran) seperti pupuk, tanah mineral, abu bakaran, dan kapur. Upaya lain adalah pengelolaan air yaitu drainase dan irigasi.

Abstract

The rapid development of settlements, industry and infrastructure in the city of Bekasi has resulted in increased pollution, reduced the amount of agricultural land used as a food producer and a source of oxygen. To minimize this impact, it is necessary to have community service in the form of urban farming activities using the green wall method. The method of implementation is in the form of outreach and training, such as (1) Providing knowledge and understanding regarding urban farming and procedures for making green walls, (2) Carrying out green wall making practices. The results of its activities are the presentation of the extension material which includes the history of green walls in the world, types of green wall, the main structure of green wall, green wall containers, green wall planting media, types of plants for green wall, watering techniques on green walls, the concept of laying out green wall, and practice of making green wall (tools and materials, as well as work steps). Furthermore, the practice of making green wall (done outdoors). At the practical stage, the community is invited to be directly involved in assembling materials and arranging plants on the media so that a green wall is formed. This green wall creation program is very useful, gives satisfaction, and the program can be continued independently by partners.
