In this study, we (i) estimated soil pH buffering capacity and microbial activity, (ii) quantified crop productivity influenced by different biochar amendment rates and N fertilizer management practices based on a factorial treatment design. Particularly, biochar was amended at rates of 0, 5, 20, and 40 Mg/ha; N fertilizer was applied at zero (N0), 122 kg/ha of urea (56 kg/ha of N; N1) and 4.8 Mg/ha of aged dairy cattle manure (56-60 kg/ha of N), providing a total of 12 treatments (four biochar rates × three fertilization practices). The combination of biochar and inorganic N fertilizer such as urea appeared to have positive impacts on the short-term biomass production, soil pH buffering capacity, and enhanced soil microbial activity for short-season forage radish production (<em>P</em> &lt; 0.05). Future research is warranted to evaluate the use of biochar in field-based forage/vegetable studies in Tennessee.</p> Todd Pirtle, Lee Rumble, Michael Klug, Forbes Walker, Song Cui, Nathan Phillips ##submission.copyrightStatement## http://creativecommons.org/licenses/by/4.0 https://cirworld.com/index.php/jaa/article/view/8035 Thu, 31 Jan 2019 04:58:52 +0000 Asexual Propagation of Four Medicinal Greek Endemic Plants of Lamiaceae Family With Conservation Priority From The Collection of The Balkan Botanic Garden of Kroussia, N. Greece https://cirworld.com/index.php/jaa/article/view/8039 <p>Conservation of endemic rare-threatened plants and sustainable exploitation of biodiversity with emphasis on medicinal-aromatic plants and plants with horticultural/ornamental value can be achieved through ex situ conservation activities. For this purpose, propagation experiments with cuttings were performed on four local Ionian endemic species with conservation priority, <em>Stachys ionica </em>Halácsy, <em>Teucrium halascyanum</em>, <em>Thymus holosericeus C</em>elak and <em>Thymus plasonii </em>Adamovic (all Lamiaceae). For propagation, softwood tip cuttings (3-5 cm) were cut at early autumn from mother plants collected from the wild and maintained in open-air mother plantations. For experimentation, the base of cuttings was immersed for 1 min in solutions of four concentrations of IBA (0, 1000, 2000 and 4000 ppm). Cuttings were placed on a peat:perlite (1:3) substrate in the bench of greenhouse heated mist system. Most suitable treatment for <em>T. halascyanum</em> (3 ½ weeks) proved to be 1000 ppm IBA (32.13 roots 1.72 cm long, 100% rooting). Accordingly, 2000 ppm IBA gave 100% rooting for both <em>S. ionica</em> (28.5 roots 1.56 cm long,) (3 weeks) and <em>Th. holosericeus</em> (4.4 roots 1.76 cm long) (7 weeks). <em>T. plasonii</em> cuttings treated with 2000 ppm IBA gave 85.71% optimum rooting with 8.67 roots 1.78 cm long.</p> Virginia Sarropoulou, Eleni Maloupa ##submission.copyrightStatement## http://creativecommons.org/licenses/by/4.0 https://cirworld.com/index.php/jaa/article/view/8039 Thu, 31 Jan 2019 04:59:06 +0000
