BACKGROUND: Mineral nutrition is one of the most important factors affecting plant growth and productivity, also growth analysis is a way to assess what events occurs during plant growth. OBJECTIVES: The goals of this study were to investigate the effect of different level of nitrogen fertilizer and zinc sulfate on growth indices of Green bean. <str...

  The aim of this research was to evaluate the effects of oral recombinant bovine somatotropin (RBS) 1% on growth performance of rainbow trout (Oncorhynchus mykiss). 600 rainbow trout weighing 46±1 grams were randomly allotted in two groups including: 1) the control group and 2) RBS treated group, each in three replicates. The fish were hand-fed with commercial pellets. The fish received 200g R...

Growth, feed conversion ratio and fillet composition of rainbow trout (initial weight of 9.99&plusmn;0.109)were investigated in a 6x2 factorial design experiment employing two levels of digestible energy (DE) (2900 and 3500kcal.kg-1) and six feeding rates (1.0%, 2.0%, 3.0%, 4.0%,5.0% of the body weight,(BW) day-1 and to satiation) for 60 days. Specific growth rate (SGR) was highest at 5.0% rati...

An initial experimental study was conducted to evaluate the effects of binaural beats on fish growth performance. A 90-day trial with four triplicate groups was conducted with 240 zebrafish, Danio rerio, under aquarium conditions. Binaural beat file complexes were played for each aquarium using computer controlled directional speakers for 0 min d-1(Control), 90 min d-1(Group 1), 180 min d-1 (Gr...

evaluation of carbon sequestration ability by chlorella vulgaris in water with different salinity expanded abstractintroductionnowadays, cultivation of microalgae in order to reduce co2 has gained attention all around the world. one of the outstanding features is that photosynthetic efficiency of microalgae is greater than that of terrestrial plants. carbon dioxide (co2) has been known as one o...
