The habitat destruction and land-use changes caused the decline of animal composition in many tropical regions. Here, we study diversity herpetofauna lowland areas Sumatera Barat, a midwestern province island, using visual encounter survey method. surveyed included rubber plantations, streams, paddy fields, peat swamps. We observed 338 individuals representing 44 species from 14 families with a...

Organic vegetable production has specific research and innovation requirements which are not shared by other parts of the food and farming sector. A pot experiment was conducted to investigate the interactive effects of few permitted organic inputs such as arbuscular mycorrhizal fungi, biochar, and different ratios of peat:worm casting on tomato (Solanum lycopersicum L.) growth, mycorrhizal dep...

melon produced by transplanting cause seed saving, reduce the risk of cold, pest and disease stress. in order to investigate the effects of growing medium and cultivars on characteristic of melon's transplants, an experiment was conducted based on randomized completely design with 10 replications at the ferdowsi university of mashhad during 2010. treatments included 6 levels of growing medium (...

Abstract Tropical peat swamp forests are major global carbon (C) stores highly vulnerable to human intervention. In Peruvian Amazonia, palm swamps, the prevalent ecosystem, have been severely degraded through recurrent cutting of Mauritia flexuosa palms for fruit harvesting. While this can transform these C sinks into significant sources, magnitude fluxes in natural and disturbed conditions rem...

to study the effect of different substrates on growth and yield of gerbera, this experiment was carried out as randomized completely block design with 14 treatments and 3 replications. treatments were as fallowing: fine sand, peat+fine sand (25%+75%), peat+fine sand (50%+50%), perlite+peat (75%+25%), perlite+peat (50%+50%), perlite+peat (25% +75%), perlite+peat+expanded clay (25%+70%+5%), perli...
