understanding of relations and interactions between ecosystem’s components and plants is one of the main conditions for sustainable production of medicinal plants. to study the effect of simultaneous application of organic and biological fertilizers on yield and yield components of zucchini squash, a split plot arrangement of factors based on randomized complete block design with tree replicati...

to study the effect of different fertilization systems on forage quality and secondary metabolites ofmedicinal forage in additive intercropping of alfalfa and fennel an experiment was conducted as split plotbased on randomized complete block design with three replications at college of agriculture, shaheduniversity in tehran, 2011. the main plots were allocated to different levels biofertilizer...

The main goal of this study was to quantify within and between field variability in mapping agricultural crop types, their biophysical characteristics, and yield for precision farming applications using near-real-time and historical (archival) Landsat TM images. Data for 6 crops (wheat, barley, chickpea, lentil, vetch, and cumin) were gathered from a representative benchmark study area in the s...

One metabolism trial and 2 finishing trials were conducted to evaluate the effects of adding corn bran and steep liquor (steep) in replacement of dry-rolled corn (DRC) on diet digestibility, cattle performance, and nutrient mass balance in open feedlot pens. The metabolism trial (Exp. 1) used 8 ruminally cannulated heifers in a 4 × 4 Latin square design and the 2 finishing trials used 128 steer...

that are in excess of the crop P removal. Excess P can accumulate in the soil and can increase P in runoff. Pote To utilize manure P for crop production, P release and plant availet al. (1996, 1999) found increased P loss in runoff as ability needs to be quantified. An incubation study was conducted to determine P availability from swine (Sus scrofa) and cattle (Bos tauthe soil P test increased...

The losses of nitrogen (N) fertilizer applied to the soil microenvironment reduce its efficiency. Different strategies like use polymer coating and chemical nitrification inhibitors had been employed N losses. But these are very expensive. Thus, a study was conducted investigate effects different concentrations Parthenium extract, neem oil, acidulated cow dung compost extract on dynamics in soi...

canola (brassica napus l.) is one of the most important oil seed crops. in order to evaluate the effects of integrated fertilization (chemical, manure and biofertilizers) on canola (b. napus variety hyola 401) yield and uptake of mineral nutrients in saline soil and water, a field experiment was conducted in randomized complete blocks (rcbd) arrangement with eight treatments in three replicatio...

Growth-promoting implants offer beef cattle producers a safe and effective way to increase calf weight gains. Implants increase production of muscle tissue and often reduce body fat production. This results in significant improvements in both growth rate and feed efficiency. Despite the proven benefits of implant use, only 11.9 percent of beef cattle operations surveyed by the National Animal H...


 This study aimed to determine the effect of glycerol concentration on motility, viability and abnormalities frozen thawed spermatozoa Bali cattle. The was conducted using a completely randomized design with 5 treatments 6 replications. consisted T0 (0% glycerol), T1 (6% T2 (12% T3 (18% P4 (24% glycerol). results showed that administration had very significant (p<0.01) viability, abnor...
