This research was conducted to determine the physical and mechanical properties of origin mixed soil with added steel slag (SS) bamboo leaf ash (BLA) classification based on Unified Soil Classification System (USCS) guidelines. study used a mixture variations (0% SS ; 0% BLA), (20% SS; 10% (40% (60% SS, 10 % (100% BLA) curing time 0 7 days. The test in this unsoaked CBR test. In USCS type syste...

to study the effects of different n fertilizer on berseem clover forage quality in an intercropping with basil, this experiment was conducted in research farm of college of agriculture, university of tehran in 2011. experimental treatments were arranged as split plots based on a randomized complete block design with three replications. different n fertilizers consisted of control (no n fertiliz...

A study was conducted to investigate the effect of different planting densities and nitrogen doses on essential oil content and yield in herb and leaves of basil (Ocimum basilicum L.). The research was conducted during 2007 and 2008 using split-plot randomized complete block design with four replications. The experiment consisted of four plant densities (30×20, 40×20 and 50×20 cm) as the main p...

One of the crucial elements for livestock and human nutrition is selenium and its deficiency or toxicity can harm human and livestock health. The present study is designed with the aim of studying the effect of different levels of selenium fertilizer (Selcote-Ultra) and cow manure on the uptake of selenium in tall fescue. For this purpose, a pot experiment with complete randomized block design ...

the use of vermicompost and fall fertilization in soilless culture on strawberry cv. camarosa quality characteristics was evaluated in a factorial based on completely randomized design pot experiment with 5 replicates. experimental treatments were four chemical fertilization timings (no fertilizer, using fertilizer at fall, spring, fall + spring) and three levels of vermicompost (10, 20 and 40%...

introduction although using animal manures and crop residues as a traditional method for increasing soil fertility and crop yield has a long history but conventional agricultural systems rely on the use of chemical fertilizer due to its immediate availability of nutrients. in many of modern agricultural systems using chemical fertilizers as a fast and easiest way to reduce nutrient deficiency a...

sixteen multiparous lactating buffaloes after 8 weeks of calving and weighing 500 to 600 kg were used in a complete switch-back design with four groups. buffaloes in the first group were fed the control ration (r1) consisted of dm basis of 60% concentrate feed mixture (cfm)+20% rice straw (rs)+20% berseem hay (bh), while in the other groups the rations consisted of dm basis of 40% cfm+20% rs+40...

One of the possibilities to achieve energy neutrality wastewater treatment plants (WWTPs) is implementation anaerobic co-digestion strategy. However, a key factor in its successful on technical scale application components with complementary composition sewage sludge (SS). In 7resent study, influence adding various co-substrates balance digestion was evaluated. The following organic wastes were...
