in order to examine the effects of biological and chemical fertilizers with the use of salicylic acid on the agronomic characteristics of corn as a factorial experiment in randomized complete block design with three replications at the agricultural research station in 2011 was boroujerd. factors examined included three levels of phosphorus fertilizer (0, 100 and 150 kg ha), two levels of biolog...

Chickpea (Cicer arietinum L.) is a native crop of Asia which is grown worldwide including Iran.In this study,different selection criteria including correlation,regression and path analysis were used to improve yield.The experimental design was split plot with RCBD replicated four times in which three sowing dates (5 January,4 February,and 5 March) were used in main plots and four genotypes;two ...

A sensitive and specific HPLC method with internal standard was developed and validated to determine vitexin-2”-O-rhamnoside (VOR) in rat plasma after oral and intravenous administration. VOR presented a very low bioavailability, the P-glycoprotein inhibitors such as verapamil and ketoconazole and absorption promoting agent, i.e. bile salts were therefore respectively applied to investigate the...

in order to determine the relationship between the variables grain yield and biological yield and some important agronomic traits, and to find the direct and indirect effects of important agronomic traits on both grain and biological yields, 364 soybean genotypes (3 planting dates) were studied. the study was based on a design augmented with 3 checks and 6 blocks implemented, in seed and plant ...

The importance of organic fertilizers for sustainable agricultural production is an undeniable fact. aim this study to determine the effects different on growth and quality properties maize plants. Three types fertilizers; cattle manure, vermicompost leonardite, their doses 2.500, 5.000, 7.500 10.000 kgha-1 were used in experiment. In addition, conventional non-fertilized as control application...

in order to evaluation the effect of mixed cropping on yield and agronomical characteristics of wheat (triticum aestivum l.) varieties, a field experiment based on a randomized complete block design with four replications was carried out at city of mahvelat in khorasan razavi province, iran, during growing season of 2007-2008. treatments including five sole cultures of conventional wheat cultiv...

a field study was conducted at the college of agriculture, shiraz university, shiraz, iran to evaluate the effect of different crop residue and nitrogen rates on yield and yield components of two dryland wheat (triticum aestivum l.) cultivars. the experiment was conducted as a strip split plot with four replications. vertical plots included two dryland current wheat cultivars (azar2 and nicknej...
