Determination of chlorophyll and carotenoid content is an important way obtaining information about the plant's photosynthetic activity as well indirect method assessing productivity plant crops, particularly grain crops. The objective this study was to evaluate role in formation emmer wheat (Triticum dicoccum (Schrank.) Schuebl) grown under traditional organic farming systems different pre-sow...

low temperature (lt) acclimation, phenological development and vernalization requirement are known to influence the expression of frost tolerance (ft) in winter cereals. a phenotypic study was undertaken to determine the interrelationship between developmental stages and ft in hardy winter wheat and rye cultivars acclimated under field condition in the cold and temperate regions of iran. winter...

Cover crops constitute one of the most promising agronomic practices towards a more sustainable agriculture. Their beneficial effects on main crops, soil and environment are many and various, while risks and disadvantages may also appear. Several legumes show a high potential but further research is required in order to suggest the optimal legume cover crops for each case in terms of their prod...

The relative suitability of potato and crops frequently grown in rotation with potato as hosts for Pratylenchus penetrans was evaluated. Suitability of rye, wheat, corn, oat, sorgho-sudangrass, and potato were compared in pot studies based on ratios of final population : initial population density and densities of nematodes in roots at harvest. Population densities increased more on potato, oat...
