Estimating Almond Crop Coefficients and Physiological Response to Water Stress in Semiarid Environments (SW Spain)
Water is the most limiting factor in irrigated agriculture, mainly in Mediterranean environments, as in the case of southwest Spain. In this area, almond is one of the most valuable crops due to its high drought tolerance. This work examines the crop coefficients (KC) based on four drainage lysimeters installed in an experimental young almond orchard. Complementary, two...
Effect of Nitrogen Fertilization and Microbial Preparations on Nmin Content in Soil after Potato Harvesting
A three–year field experiment was conducted under conditions of Luvic Chernozem soil. Diversified nitrogen fertilization with 0, 60, 120, and 180 kg N ha–1, and microbial preparations improving soil properties were applied to potatoes, cv. ‘Satina’, cultivation. N–NO3 concentration in the soil profile (0–0.9 m) in autumn after potato harvesting fluctuated from 28 kg N ha–1 in the N0...

Association of Some Photosynthetic Characteristics with Canopy Temperature in Three Cereal Species under Soil Water Deficit Condition
Canopy temperature (CT) is used as a selection tool to improve crop adaptation to drought. The aim of this work was to investigate association of some photosynthetic characters with CT during grain filling in three cereal species. For this objective, a two–year study (2009–2011) was carried out in Kurdistan Province in western Iran. Four genotypes of triticale, three cultivars of bread...

تحلیلی برآثار شرط حفظ مالکیت
قدر متیقن از شرط حفظ مالکیت در معنای عام آن تاخیر انتقال مالکیت است، اما شکل رایج این شرط ـ که بحثهای دکترین و رویه قضایی خارجی عمدتاً بر آن متمرکز است ـ مبتنی بر اثر تاخیری نیست، بلکه کارکرد آن تعلیق تملک مبیع است. در مقابل این شرط، مسیر نظامهای حقوقی مختلف از هم جدا میشود. برخی از کشورها مانند فرانسه این شرط را پذیرفتهاند اما با تفسیر مضیق و سختگیرانه موارد کاربرد آن را محدود...
