in order to study the influence of nitrogen and different harvesting dates on sorghum yield, a split plot experiment based on randomized complete block design was conducted with three replications in 2010 at the research farm of islamic azad university, ardabil branch. factors were: different harvesting dates in three levels containing, beginning of flowering, two and four weeks after beginning...

ABSTRACT Watermelon (Citrullus lanatus) is a succulent fruit and vine-like plant that cultivated in Mexico it generates employment currency for the country. However, there need to research what local organic substrates can substitute peat moss as culture medium produce watermelon seedlings of good quality at low cost. The objective this study was evaluate physical chemical properties five subst...

Commercial forest plantations in Chile are dominated by pine (Pinus radiata) and eucalyptus (Eucalyptus globulus). Tree bark is the main by-product of forestry industry has low value, but great potential for use as an agricultural substrate. However, direct fibers may cause plant phytotoxicity due to presence polyphenolic other compounds. This study aims evaluate physicochemical properties E. g...

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...

We found that peat moss, amended with various ratios of pellets comprised of equal proportions of biochar and wood flour, generally had chemical and physical properties suitable for service as a substrate during nursery production of plants. High ratios of pellets to peat (>50%) may be less desirable because of high C:N, high bulk density, swelling associated with water absorption, and low volu...

During oil-sands mining all vegetation, soil, overburden, and oil sand is removed, leaving pits several kilometers wide and up to 100 m deep. These pits are reclaimed through a variety of treatments using subsoil or a mixed peat-mineral soil cap. Using nonmetric multidimensional scaling and cluster analysis of measurements of ecosystem function, reclamation treatments of several age classes wer...
