in order to investigate effect of application of nitroxin and nitrogen chemical fertilizer on yield and yield components, split plot experiment on the basis of randomized complete block design with four replications was conducted. four levels of nitrogen fertilizer (n1: 100% chemical fertilizer, n2: 75% chemical fertilizer + 100% biological fertilizer, n3: 50% chemical fertilizer + 100% biologi...

in order to study the effects of irrigation water salinity and leaching fraction on soil chemical characteristic, grain yield, yield components and sodium and potassium contents in leaves of safflower, an experiment was coducted in a split plot design with four replications in 2009 at roudasht, isfahan. treatments included three irrigation water salinities of q1=3.35, q2=8.77 and q3=11.21 ds/m ...

in order to study the effect of n fertilizer rates on morphological traits, yield and yield components of rice cultivars, a study was carried out in rice research institute of rasht, iran during 2009. it was a two-variable factorial experiment based on a randomized complete block design with three replications. the first factor was nitrogen fertilization at four rates of 0, 30, 60 and 90 kg n h...

Genotypic variation is useful to breeders when selecting genotypes to improve particular traits. Inorder to study of genetic diversity 20 genotypes of Hordeum murynum studied in the form of randomized complete block design the experimental field of islamic azad university shahre rey branch with 3 replication in the year 2012. Notes traits was conducted including days to heading, days t...

introduction: expansion of the area of oilseed crops such as soybean is one of the policies of iranian agricultural policy makers as iran is one of the major oilseed importers in the world. however, the area of this crop in kermanshah province is negligible, but it could be cultivated in most parts of this province. the quantity and quality of the produced grain could be affected by environment...
