to study the effect of urea application in safflower (carthamus tinctorius) and determination of effective traits on its yield, a factorial experiment based on randomized complete block design in three replications was conducted in tabriz, iran, during 2012. studied factors were urea rate levels as 100, 150 and 200 kg/ha and urea application times 100% in sowing time, 50% sowing time + 50% stem...

The application of fertilizers as a topdressing in maize raises serious concerns because too much fertilizer is retained the upper leaves, causing burning to tissues. In this study, use controlled-release and stabilized (with 3, 4-dimethylpyrazole phosphate) was compared with conventional split into two equivalent applications forage maize-oats cropping system. maize, 100 200 kg N ha−1 differen...

Three experiments were conducted to evaluate the effects of diet and monensin on performance, digestibility, and methane production in steers fed forage-based diets. In Exp. 1, 72 individually fed steers (300 ± 25 kg) were used in a randomized block design arranged as 2 separate 2 × 2 factorials with two common treatments, thus 6 diets were fed with 12 steers per treatment. Factors included hig...

Abstract—Nitrogen fertilizer is the most used and often the most mismanaged nutrient input. Nitrogen management has tremendous implications on crop productivity, quality and environmental stewardship. Sufficient nitrogen is needed to optimum yield and quality. Soil and in-season plant tissue testing for nitrogen status are a time consuming and expensive process. Real time sensing of plant nitro...

The objective of this study was to evaluate the performance of growing cattle when intensively grazing stockpiled endophyte-infected (E+), endophyte-free (E-), and nontoxic endophyte-infected (EN) tall fescue during the winter. The experiment was conducted over 5 consecutive winters. In each year, plots (1 ha each, 4 per treatment) were harvested for hay in August, fertilized in September, and ...

The goal of the study was to explore hydraulic traits in a 4-year-old loblolly pine (Pinus taeda L.) plantation to better understand plasticity of this species to resource availability. The influence of a factorial combination of irrigation (130 mm year 1 versus 494 mm year ) and fertilization (0 kg N ha 1 year 1 versus 80 kg N ha 1 year ) on stand-level transpiration, canopy stomatal conductan...
