Scarcity of irrigation water and increasing soil salinization has threatened the sustainability of forage production in arid and semi-arid region around the globe. Introduction of salt-tolerant perennial species is a promising alternative to overcome forage deficit to meet future livestock needs in salt-affected areas. This study presents the results of a salinity tolerance screening trial whic...

The fungus Acremonium coenophialum is endophytically associated with tall fescue (Festuca arundinacea Schreber). Within this symbiotum the fungus produces ergopeptide alkaloids, which are associated with livestock toxicoses. Environmental effects on the production of ergot alkaloids within the symbiotum are unknown. We conducted a greenhouse study of the effects of flooding, nitrogen rate durin...

پتاسیم به همراه نیتروژن و فسفر سه عنصر ضروری برای رشد گیاه تلقی می شوند که نقش های بسیار مهمی در گیاهان دارند. پتاسیم عنصر هفتمین عنصر غذایی فراوان در لیتوسفر بوده و در بین کاتیونها بیش از بقیه توسط گیاه جذب می شود. در نتیجه کشاورزی متمرکز و کشت مداوم گیاهان به ویژه گیاهان پرنیاز، منابع در دسترس این عنصر در خاک محدود شده است. پرداختن به راهکار زیستی یکی از روشهای تأمین پتاسیم گیاه می باشد بر ای...

High cation exchange capacity and organic matter content of crude humic substances from compost could be exploited to reduce ammonia loss from urea and to as well improve rice growth and soil chemical properties for efficient nutrients utilization in lowland rice cultivation. Close-dynamic air flow system was used to determine the effects of crude humic substances on ammonia volatilization. A p...

St. Augustinegrass (Stenotaphrum secundatum) cv FX-313 was used as a model laboratory host for monitoring population growth of the sting nematode, Belonolaimus longicaudatus, and for quantifying the effects of sting nematode parasitism on host performance in two samples of autoclaved native Margate fine sand with contrasting amounts of organic matter (OM = 7.9% and 3.8%). Following inoculation ...

Introduction One-pot oxidation reaction consisted of direct synthesis of hydrogen peroxide (H2O2) from H2 and O2 gases and oxidation reaction using in situ generated H2O2 is promising synthetic method, because it is possible to use the unstable H2O2 immediately without isolation/purification steps, which would contribute to energy and time saving as well as avoid the risk of transportation of t...

Zinnia is a very attractive and beautiful ornamental plant due to the diversity of color and flowering period. The effect of cycocel and pot size was studied on growth and flowering of zinnia in a factorial experiment based on a randomized complete design with two factors: cycocel at 3 levels (0, 1000 and 2000 ppm) and pot size at 4 levels (10, 12, 14 and 16 cm) with 12 treatments and 3 replica...
