Intercropping systems compared to monoculture systems can more efficiently use the existing resources which ultimately will lead to increased plant performance. Therefore, to evaluate the benefits of intercropping maize and beans and assess its impact on yield and yield’s component, an experiment was conducted in factorial design with randomized complete block design in three replication, in 20...

to study the effect of planting date, plant density and planting pattern on yield of corn (zea mays l) var. ksc 647 split plot factorial experiment in a randomized complete block design with four replications at bayranshahr lorestan province in crop year 2015 was conducted. factors examined included planting date in three levels: (25 may, 12 june and 29 june), density at three levels (60, 75 an...

to study effect of fe and zn spraying on some characteristics of mungbean, an experiment was designed as factorial based on randomized complete block with three replications in urmia university, 2012. treatments were nutrition systems (organic, chemical, integrated and no nutrition) and micronutrients (fe, zinc, no foliar application and water spraying). the plant height, pod length, number of ...

understanding of physiological responses of salt tolerance might be lead to identify main salt tolerance mechanisms and essential approaches for improving grain yield stability, and also to select salt tolerant wheat cultivars. thus, the effects of salinity were investigated on grain yield and some of the characteristics related to salt tolerance. six wheat cultivars (roshan, kavir, karchia, ga...

Tree mapping grammars are used in natural language generation (NLG) to map non-linguistic input onto a derivation tree from which the target text can be trivially read off as the terminal yield. Such grammars may consist of a large number of rules. Finding errors is quite tedious and sometimes very time-consuming. Often the generation fails because the relevant input subtree is not specified co...

Neutralization of Acidic Sulfur Species by Calcite in Mineral Aerosols Collected in China and Japan Studied by Ca K-Edge X-Ray Absorption Near-Edge Structure Spectroscopy X-ray absorption near-edge structure studies at the calcium K-edge have been used to show that acidic sulfur species in the atmosphere (e.g., H2SO4), mainly released by human activities, can be neutralized by the calcite prese...

This experiment was laid out in order to evaluate the effects  of different biofertilizers on yield components of barley. The experiment was a factorial design with three replications. Treatments were three nitrogen biofrtilizers (Nitroksin, Nitrokara and Supernitroplass) and three phosphate  biofrtilizers (Phosphate barvar2, Biozarr and Superplass) with control for them and yield components we...

cumin (cuminum cyminum l.) is one of the most important cultivable medicinal plants in iran and today, it is the second most popular spice in the world after black pepper. it is essential to know the relationships between yield and its components in cumin breeding programs. therefore, different multivariate statistical analysis was performed on plant characters in cumin to determine the relatio...

soil compaction has become a widespread problem in the world and is one of the factors involved in land degradation and declining crop yields, especially in the arid and semi-arid agriculture. the purpose of this study was to investigate the effects of subsoil compaction on morphological, physiological and agronomic aspects of wheat .the research was carried out in the experimental farms of anb...

fruit yield efficiency and some vegetative characteristics of commercial and spur type apple. cultivars was evaluated in dr. nakhjavani field station, orumieh, iran, in 2008 and 2009 growing seasons. apple cultivars included: red spur, red chief, golden spur, yellow spur, fujii, red delicious, cooper spur, red cooper spur, jonathan, golden delicious, oregon spur, jonagold. the experimental desi...
