controlled environment may be adopted for a rapid multiplication of a large number of potato seed tubers. the controlled environment prevents seed tuber degeneration which may occur under field conditions. the objective of this study was to introduce new mini-tuber production system with high multiplication rate and low production cost. to evaluate the performance of culture systems in terms of...

Water availability and pH are important factors to consider determine the suitability of a material for use as growing medium. Unfortunately, most horticultural substrates characterized by their water repellency. This is case with peat moss which hydrophobic acidic. Synthetic surfactants required improve its wettability. In this study, combination phosphorylated wood pulp fibers (FLP) zeolite p...

The removal of volatile organic compounds (VOC) in biofilters packed with organic filter beds, such as peat moss (PM) and pine sawdust (PS), frequently presents drawbacks associated to the collapse of internal structures affecting the long-term operation. Poly(ethylene ether carbonate) (PEEC) groups grafted to these organic carriers cross linked with 4,4'-methylenebis(phenylisocyanate) (MDI) pe...

Members of the phylum Planctomycetes are common inhabitants of northern wetlands. We used barcoded pyrosequencing to survey bacterial diversity in an acidic (pH 4.0) Sphagnum peat sampled from the peat bog Obukhovskoye, European North Russia. A total of 21189 bacterial 16S rRNA gene sequences were obtained, of which 1081 reads (5.1%) belonged to the Planctomycetes. Two-thirds of these sequences...

The present study was conducted to evaluate the effect of different growing mediums {sand, peat moss, and mix (sand + moss 1:1 v/v)} spraying with 0,100 150 mg L-1 humic acid on vegetative root parameters “Wonderful” pomegranate hardwood cuttings at Bakrejo nursery station, Sulaimania city, Iraq in 2021. They were planted polyethylene black bags 15-3-2021. Using randomized complete block design...
