چکیده مقاله:

One of the goals of organic crop production is to grow species which combinetraditional pro-healthy properties, innovative cultivation practices and harmonywith the environment. Among the ancient species the spring spelt is especiallypredisposed for organic farming. In comparison with common wheat spring spelthas a relatively short research history on physiological analysis of growth anddevelopment. The objective of this study has been to compare the agronomicperformance and growth characteristics of spring varieties of Triticum spelta L. andTriticum aestivum L. cultivated in the organic farming system and sown ondifferent dates. The basis for the research were data from field plot experimentsarranged in completely randomized blocks carried out in 2010 and 2011. Thefactors were cultivars: two cultivars of T. aestivum (Trappe, Waluta) and twocultivars of T. spelta (Roter Sommerkolben, Speltz aus Tzaribrod) and sowingterms: optimal and postponed by two weeks. During the seasons there wereassessed: weed infestation and disease resistance, leaf chlorophyll index, biometricmeasurements associated with plant morphology and yielding and nutritional valueof grains. It was stated that cultivars of T. spelta are more tolerant to unfavorableenvironmental conditions than cultivars of T. aestivum, showing better adaptabilityto habitat conditions, when-due to the worse weather-the uptake of nutrients fromsoil can be limited, stronger competitiveness against weeds and higher tolerance todiseases of leaves and stems. The content of chlorophyll in spelt wheat grown in organic cultivation as well as yields are very stable across years. Underunfavourable weather conditions during the season, spelt wheat can give yieldswhich compare to yields of common wheat, but when in the favorable weatherconditions common wheat varieties generate yields higher by 42% (cv. Trappe) upto 47% (cv. Waluta).

Agronomic characteristics of the spring forms of the wheat landraces (einkorn, emmer, spelt, intermediate bread wheat) grown in organic farming

Organic farmers look to the possibilities of growing neglected crops, such as the spring forms of hulled wheat – einkorn, emmer and spelt – for support in developing the organic farming system. In 2008, 169 landraces from the gene bank at the Crop Research Institute in Prague were tested on certifi ed organic plots. The experiment was aimed at fi nding suitable varieties for the organic farming...

Agronomic performance of two intercropped soybean cultivars

Broader environmental tolerance associated with mixed population of soybean (Glycine max Merr.) cultivars may increase soybean yield potential and play a significant role in yield stability. A field study was carried out to assess whether intercropping of two commonly used cultivars of soybean with different morphological characteristics may increase seed yield in Iran. A split-plot design was ...

Anti-synchronization and synchronization of T-system

In this paper, we discuss the synchronization and anti-synchronization of two identical chaotic T-systems. The adaptive and nonlinear control schemes are used for the synchronization and anti-synchronization. The stability of these schemes is derived by Lyapunov Stability Theorem. Firstly, the synchronization and anti-synchronization are applied to systems with known parameters, then to systems...

Effects of post-anthesis heat stress and nitrogen levels on grain yield in wheat (T. durum and T. aestivum) genotypes

      In order to study the effects of post-anthesis heat stress and nitrogen levels on grain yield and yield components of wheat genotypes, two separate field experiments were conducted in delayed and optimum sowing dates under Ahvaz conditions (2006-2007). The Ahvaz site located in south west of Iran (32°20' N, 40°20' E) with subtropical climate condition. The experiment site had a moderate w...
