abstract in order to investigate the effect of different ratios of cocopeat and vermicompost as a cultural media on seed emergence and some qualitative and quantitative characteristics of sweet pepper transplant (cv. colifornia wonder). the treatments include: vermicompost + cocopeat (3:1), vermicompost + cocopeat (1:3), vermicompost + cocopeat (1:1) (v/v) and normal soil of transplant. the tre...

Pears are among the most economically important fruits in world that grown all temperate zones. Pyrus communis L., ‘Pyrodwarf®(S)’ rootstock is one of gene sources used to improve fruit productivity, resistance, and tolerance biotic abiotic stresses. Traditional propagation P. L. time-consuming limited by a short growing season harsh winter conditions. Therefore, vitro suitable alternative. Mur...

Modified versions of the Cry3A gene of Bacillus thuringiensis (Bt) were transferred into Norway spruce (Picea abies). Both the biolistic approach and Agrobacterium tumefaciens mediated procedure were employed for transformation of embryogenic tissue (ET) cultures. The latter method proved to be more efficient yielding 70 transgenic embryogenic tissue lines compared with 18 lines obtained by bio...

Abstrak. Larutan Hara AB Mix merupakan pupuk majemuk campuran larut air yang sering digunakan pada sistem media hidroponik. Efektifitas ini sebagai sumber hara bagi tanaman sayur antara lain dipengaruhi oleh konsentrasi pemberian tepat. Percobaan dilakukan di dalam polybag menggunakan rancangan acak lengkap (RAL) terdiri atas 5 perlakuan larutan yaitu: 0,25; 0,50; 0,75; 1,00; dan 1,25 g L-1 den...

Perlite is a generic name for an amorphous volcanic alumina-silicate rock that expands by a factor of 4-20 when rapidly heated to 1400-1800 °F (760-980 °C). Both the ore and the expanded product have extensive and widespread commercial applications. Limited data on the toxicology of perlite in animal studies indicate that the LD₅₀ (oral ingestion) is more than 10 g/kg and, from a chronic inhala...

Cocopeat machines that have been developed today, were carried out with variations in the speed of rotation, blade length, shape, and treatment objects (coconut coir immersion). There has no development a cocopeat machine focuses on density. It is suspected density affects to difference mass produced. This study was true experiment. The dependent variable mass. independent variables density, co...

the aim of the present work was to investigate the ability of cocopeat to remove of lead (ii) from aqueous solutions. the effects of different parameters such as particle size, adsorbent dosage, ph, contact time, agitation speed and concentration on the removal process has been investigated. the maximum removal of lead ion (92.5%) took place in the ph range of 4 contact time in 30 minutes and i...
