A 3, NPK lime factorial experiment is used as a means of testing both soil and leaf norms for sugarcane obtained by the Diagnosis and Recommendation Integrated System (DRIS) developed by Beaufils. ,Soil and leaf samples were taken from the experiment when the cane was 3, 6, 12 and 18 months old respectively and analysed for a number of essential plant nutrients. The results show that these norm...

Inferences we make about underlying cognitive processes can be jeopardized in two ways due to problematic forms of aggregation. First, averaging across individuals is typically considered a very useful tool for removing random variability. The threat is that averaging across subjects leads to averaging across different cognitive strategies, thus harming our inferences. The second threat comes f...

This experiment was conducted to investigate the effects of different levels of canola oil and diet mixing time length on performance, carcass traits and blood lipids in broilers. In this experiment 288 Ross-308 broilers were used from 11 up to 42 days as factorial arrangement (3×2) included three levels of canola oil (0, 3 and 6%) and two mixing time length (10 and 15 minute) in 6 treatments, ...

Two experiments evaluated the self-handicapping hypothesis that alcohol consumption varies directly with individuals' uncertainty of their ability to perform successfully. In a 2 X 2 X 2 factorial design, Experiment 1 manipulated (a) difficulty of an initial intellectual test (insolvable or solvable), (b) feedback regarding test performance (success or none), and (c) instructions regarding the ...

The aim of this study was to evaluate the effects of copper (Cu) sulfate (0, 125 and 250 mg/kg), arginine (Arg) supplements (0, 0.1 and 0.2%) and glucosinolate content on performance and carcass traits in broiler chickens fed with canola meal based diet. During a three-week experimental period (22-42 d), 405 male broilers were used in completely randomized design with a 3 × 3 factorial experime...

effect of gibberellic acid on marigold (calendula officinalis l.) was evaluated in a pot culture experiment. a factorial experiment based on completely randomized design including 12 treatments and four replications was carried out. main factor was foliar application stages (first, second and third) and sub factor included different concentrations of ga3 (0, 50, 150 and 250 mg l-1). results sho...

An experiment was conducted to study the effects of enzyme and phytogenic product (thymol+carvacrol) on the ileal microbial population and jejuna and ileal histomorphology of broilers fed wheat based diet. The experiment was conducted as a 2 × 3 factorial arrangement with 2 levels of enzyme endofeed W (0 and 0.05%) and 3 levels of next enhance 150® (0, 100 and 200 mg/kg). Each of the 6 dietary ...
