the effect of crop residue and different npk fertilizer rates on yield components and yield of wheat
introduction integrated nutrient management involving crop residue/green manures and chemical fertilizer is potential alternative to provide a balanced supply of nutrients, enhance soil quality and thereby sustain higher productivity. the present experiment was undertaken to evaluate the effect of different crop residue management practices and npk levels on yield components and yield of wheat....
Zinc (Zn) deficiency caused by inadequate dietary intake is a global nutritional problem, particularly in developing countries. Therefore, zinc biofortification of wheat and other cereal crops is being urgently addressed and highly prioritized as a research topic. A field study was planned to evaluate the influence of zinc application on grain yield, grain zinc content, and grain phytic acid co...
A field experiment was conducted to evaluate the interference effects of wild barley (Hordeum spontaneum L.) on wheat (Triticum aestivum L.) yield, in 2009. The effects of different densities of wild barley (0, 25, 50, 75, 100, 125 plants m-2) in interferences with wheat at density of 300 plants m-2 were studied in a completely block design with three replications. Results showed that with incr...
This study setout to investigate the effect of wheat residue, tillage, and nitrogen fertilizer management on some agronomic traits of soybean as a split split plot based on randomized complete block design with three replications. The main plots included wheat residue management: collecting and leaving residue and sub plot included tillage (without tillage and conventional tillage), and the sub...
Selection for drought tolerance typically involves evaluating genotypes for either high yield potential or stable performance under drought stress. In order to select drought tolerant land races of bread wheat an experiment was conducted in a randomized complete block design (RCBD) with three replications under two different rainfed and irrigated conditions during the growing season 2010-2011. ...
EPTD Discussion Papers contain preliminary material and research results, and are circulated prior to a full peer review in order to stimulate discussion and critical comment. It is expected that most Discussion Papers will eventually be published in some other form, and that their content may also be revised. ACKNOWLEDGMENTS The authors would like to thank Susanne Neubert and John Pender for h...
Grain yield in wheat is influenced directly and indirectly by other plant characteristics. One of the main goals in wheat breeding programs is increase of grain yield. Considering the role of crop rotation in increasing grain yield, and in order to study the difference between crop rotations for wheat yield and yield components (Darya cultivar), an experiment was conducted with six rotation tre...
This study was conducted to determine the yield response factor (Ky) of wheat with respect to deficit irrigation at different growth stages. The experiment was conducted in Shahrekord in three crop growing seasons using randomized complete blocks design with 3 replications. Treatments consisted of five levels of deficit irrigation: E0 (full irrigation), E1 (85%), E2 (70%) and E3 (55%) of potent...
Crop yield, soil properties and erosion are strongly affected by terrain parameters. Therefore, knowledge about the effects of terrain parameters on strategic crops such as wheat production will help us with sustainable management of landscape. This study was conducted in 900ha, of Ardal district, Charmahal and Bakhtiari Province to develop regression models on wheat yield components vs. terrai...
Determining the relationships between grain yield and some yield components of wheat is most important in permanent yield production. Using path coefficient analysis in order to determine key traits affecting majorly yield, and also to study direct and indirect effects of yield and yield components, this research was performed during 2006-2009 ys using 94 doubled-haploid (DH) lines, their...
