the aim of this study was to determine the effects of ensiling and using of fertilizers nitrogen and phosphorus on chemical composition and ruminal dm degradability of safflower plant (carthamustinctorius l.). the safflower plant was cultivated at december 2009, and harvested at june 2010 in flowering stage, chopped to 3-5 cm particles and then ensiled in the laboratory silos for 60 days. the e...

This experiment was conducted to determine the effects of nitrogen and phosphorus fertilizers on nutritive value of safflower forage and silage by in situ and in vitro methods. The safflower forage was harvested at flowering stage, chopped to 3-5 cm particles and then ensiled in the laboratory silos for 60 days. The experimental treatments included: 1. Unfertilized forage (control), 2. Phosphor...

This experiment evaluated forage production, sward structure, stocking rate, weight gain per area and nutritive value of forage as grazed by beef heifers on Alexandergrass (Urochloa plantaginea (Link) Hitch) pasture fertilized with nitrogen (N): 0; 100; 200 or 300 kg of N/ha. The experiment was a completely randomized design following a repeated measurement arrangement. The experimental animals...

Forage biomass production and water storage (WS) was evaluated in cactus pear cv. Gigante fertilized with combinations of nitrogen (10, 70, 100, 130, 190 kg ha−1 yr−1 N) phosphorus P2O5) annual (AH) biennial (BH) harvest frequencies, Quixadá Tejuçuoca, Brazil. A randomized complete block design used a split-plot arrangement four replications. In Quixadá, the maximum total forage (TFB) recorded ...

in order to evaluate different sources and rates of nitrogen on dry matter yield, concentration and uptake of primary macronutrients (nitrogen, phosphorous and potassium) in forage sorghum (hybrid of speedfeed), three levels of nitrogen (80, 160 and 240 kg n ha-1) from three n sources (urea fertilizer, cattle manure and equal combination of urea fertilizer + cattle manure) and the control (no f...

in order to study the influence of municipal solid waste compost and nitrogen fertilizer on grain and forage yield of sweet corn an experiment was conducted at marvdasht during 2009. the experiment was arranged in split plots based on randomized complete block design with two factors and three replications. main plot included 5 levels of nitrogen fertilizer (100, 150, 200, 250, 300 kg n ha-1) a...

this experiment was conducted to evaluate the effects of different sowing densities and nitrogen fertilizer rates on quantitative and qualitative corn forage yield in an agroforestry system with orange trees. the treatments consisted of 4 nitrogen fertilizer levels of 0, 100, 200, and 300kg n/ha (allocated to main plots) and 4 sowing densities of 80000, 110000, 140000 and 170000 of corn seeds (...

To evaluate the effect of nitrogen fertilizer amounts on grain yield of forage corn in 2012, a pilot was implemented in Islamic Azad University Agricultural Research Station, Isfahan, as a split plot in a randomized complete block design. Main plots consisted of four levels: control (no fertilization ) , 50 , 100 and 150 kg per ha nitrogen from urea source and subplots , including several varie...
