european corn borer, ostrinia nubilalis hb. is a polyphagous insect, recognizing world widely as the predominant pest of maize. in this research the relative resistance of eleven hybrids of maize was evaluated in a field in agricultural and natural resources research center of moghan. this experiment was conducted in three replicates in a complete randomized block design. for comparison of the ...

in order to study the effect of strip intercropping of maize (zea mays l.) and bean (phaseolus vulgaris l.) on the dry matter yield and land equivalent ratio (ler) in weedy and weed free treatments, an experiment was conducted at the agricultural station of college of agriculture, ferdowsi university of mashhad, iran. treatments were strip width of 2, 3, 4 and 5 rows and sole cropping of each c...

understanding the relationship between sink and source in maize is of prime importance in maize growing regions. in this study, a field experiment was carried out during spring and summer 2007 in the experimental field of the college of agriculture, shiraz university, to examine the effects of source restriction (defoliation) on sink size (yield and its components) of  sc704 maize hybrid.  a fa...

abstract in order to evaluate the effects of different depths of irrigation by sprinkler irrigation system on water use efficiency (wue) of new early maize cultivar ksc302, an experiments was carried out in karj during 2006 and 2007. experimental design was split plot based on randomized complete blocks with three replications. main plots were three irrigation levels: 75%, 100% and 125% etc (es...

Drought has been a major cause of agricultural disaster, yet how it affects the vulnerability of maize and wheat production in combination with several co-varying factors (i.e., phenological phases, agro-climatic regions, soil texture) remains unclear. Using a data synthesis approach, this study aims to better characterize the effects of those co-varying factors with drought and to provide crit...

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...

The aim of the present investigation was to study the growth, yield and yield components of maize (Zea mays L.) single cross 704 under different levels of irrigation, plant density, and ethephon in southern Iran where this particular crop has not yet been studied in detail. A field experiment was performed in the 2004 5 growing season at the experimental farm of the College of Agriculture, Shir...

Potassium (K) fertilizer management is beneficial for improving growth, yield and yield components of field crops under moisture stress condition in semiarid climates. Field experiments were conducted to study the response of maize (Zea mays L., cv. Azam) to foliar and soil applied K during summer 2013 and 2014. The experiments were carried out at the Agronomy Research Farm of The University of...
