In order to investigate the effect of Cd and Zn on uptake, concentration and the translocation factor of the Cd and Zn in the rice plant, a factorial experiment was conducted with four factors including two rice cultivars of Vandana and Hashemi, two waterlogged and non-waterlogged conditions and three levels of Zn and Cd (0, 5 and 10 mg kg-1 soil). The experiment was carried out in a randomized...

The objective of this study was to evaluate whether the adverse effects of high dietary rice bran (RB) inclusion levels on the feed intake, performance, bone status and nitrogen (N) retention of broilers could be mitigated by wet feeding. Giving a completely randomized design experiment in 2 × 2 factorial arrangement, seventy two broiler chickens, managed in 24 floor pens received one of the tw...

in order to investigation of morphological traits, yield and its components in three cultivars of grain sorghum (kimia, sepideh, payam) and two promising lines (m5, m2) under four density (240000, 205000, 170000 and 135000 plant/m2), experiment was conducted as factorial design based on randomized complete block design with three replications in birjand agricultural research station, during 200...

Minimum aberration designs are obtained for two types of mixed-level fractional factorial: (i) (s) × s factorial, and (ii) (s1) × (s2) × s factorial, where s is any prime or prime power, and r, r1, r2 and n are positive integers. Projective geometric tools are employed to find the wordlength pattern of a given design in terms of that of its complementary set. Many useful designs are found

to the amount of root growth under the various conditions. At the termination of the experiment nearly all the nematodes were found within the tomato roots. T h e numbers found outside the root were somewhat greater at low light intensity than at high light intensity, particularly at the high inoculum level. Roots produced at the low light intensity were probably insufficient to support the hig...

Effects of sodium selenite (SS) in offspring of broiler breeders has been reported, but the comparison between SS and different level of methionine on offspring has received limited, so this study was conducted to investigate sodium selenite and methionine effects on concentration of selenium in egg and serum of Iranian native broiler breeders. An experiment was conducted in 3 × 3 factorial exp...
