This study was designed to investigate the effects of supplementation of spent mushroom substrates (SMS) on rumen fermentation and blood metabolites in Hanwoo steers. The experiment was conducted as a duplicated Latin square design with six Hanwoo steers (600±47 kg), each permanently fitted with a ruminal cannula. There were three treatments; i) control (concentrates 4.8 kg +rice straw 1.2 kg/d...

Rubber processing industry effluent represents a serious environmental pollution problem especially for underground and surface water. Wastewater collected from rubber processing industry was characterized for their pollution characteristics. Analysis showed that the biological oxygen demand (BOD), chemical oxygen demand (COD), total dissolved solids (TDS), total suspended solids (TSS), total s...

Plastic mulch increased minimum temperature of soil, accelerated plant height,early growth, early yield, and bring satisfactory weed control without anyapplication of herbicides. This experiment was laid out on three-factorialRandomized Complete Block Design with three replications during 2008-2010 atthe National Rice Research Institute, Rasht, Iran using three kinds of mulches(Transparent and ...

Rice is a typical silicon-accumulating plant. Silicon (Si), deposited as phytoliths during plant growth, has been shown to occlude organic carbon, which may prove to have significant effects on the biogeochemical sequestration of atmospheric CO2. This study evaluated the effects of silicate fertilization on plant Si uptake and carbon bio-sequestration in field trials on China's paddy soils. The...

A field experiment was conducted to evaluate the different brands of zinc fertilizer produced and marketed in different areas of Bangladesh and their effect on nutrients content in rice (BRRI dhan 32). Among the nutrients; the content of N, S and Ca in grains and straw did not vary significantly, but the contents of P, K, Na, Mg, Zn, Cu, Fe and Mn in grain and straw varied significantly due to ...

In this study, a fixed-site field experiment was conducted to study the influence of different combinations of tillage and straw incorporation management on carbon storage in different-sized soil aggregates and on crop yield after three years of rice-wheat rotation. Compared to conventional tillage, the percentages of >2 mm macroaggregates and water-stable macroaggregates in rice-wheat double-c...

The influence of crop residue amendments on the chemical properties of an acid soil and rice yields was investigated at Abakaliki for two cropping growing seasons (2006 and 2007). The residue treatments were rice straw, burnt rice husk and legume residue, while the rice cultivars were ITA 315, Ex-China and ITA 257. The design of the experiment was a 3 x 4 factorial in a Randomize Complete Block...

the effect of phosphorus supplementation to ammoniated rice straw was studied. the in vitro experiment was carried out following the first stage of tilley and terry method. the treatments consisting of four diets were a= 50% ammoniated rice straw + 50% concentrate (control), b= a + 0.2% phosphorus (p) supplement, c= a + 0.4% phosphorus (p) supplement, and d= a + 0.6% phosphorus (p) supplement o...

Grifola frondosa is an economically important edible and medicinal mushroom usually produced on substrate consisting of sawdust supplemented with wheat bran. Cultivation of G. frondosa on crop straw (corn cob, corn straw, rice straw, and soybean straw) as a substrate was optimized by using the D-optimum method of the simplex-lattice design, and the alternative of crop straw as a substitute for ...
