parsley has a very high nutritional value, containing a, b and c vitamins and mineral nutrients. in order to investigation of the effect of different nitrogen sources on parsley an experiment conducted in a factorial combination of three nitrogen forms (calcium nitrate, ammonium sulphate and urea) and four nitrogen levels (0, 100, 125, 150 kg ha-1) by using a factorial experiment based on rando...

OBJECTIVE To study the effects of the addition of hyaluronidase (HA) to an etorphine/azaperone drug combination on induction times of immobilization. STUDY DESIGN Experimental part-randomized 'blinded' cross-over study. ANIMALS Eight wild managed blue wildebeest (Connochaetes taurinus). METHODS Animals were immobilized, on separate occasions separated by two weeks, with one of four treatm...

Objective: An experiment was conducted at Wondo Genet Agricultural Research Center in the production season of 2013/14 and 2014/15 with the objective of identifying the best combination of intra and inter-row spacing for optimum plant population density of stevia. Methods: The experiment was conducted using five intra-row spacing (20cm, 25cm, 30cm, 35cm, and 40...

in order to evaluate the effects of ethephon and nitrogen fertilizer on sweet sorghum cv. sofra, an experiment was conducted as split plot on a randomized complete block design with three replications at agricultural research station of isfahan university (isfahan, iran). experiment was conducted with four nitrogen levels (0, 100, 200 and 300 kg urea ha-1 from urea with 0, 46, 92 and 138 kg nit...

the interaction between nitrogen levels: 100, 150 and 175 kg ha-1, as ammonium sulfate (ams) and glyphosate: 1) 61.5 gr a.i. ha-1 sprayed in three parts, 30, 40 and 50 dap, 2) 61.5 gr a.i. ha-1 sprayed in two parts, 30 and 50 dap, 3) 86 gr a.i. ha-1 sprayed in three parts as level one, 4) 86 gr a.i. ha-1 sprayed in two parts as level two on broomrape shoot density and dry mater and tomato yield...

Cover crop benefits include nitrogen accumulation and retention, weed suppression, organic matter maintenance, and reduced erosion. Organic farmers need region-specific information on winter cover crop performance to effectively integrate cover crops into their crop rotations. Our research objective was to compare cover crop seeding mixtures, planting dates, and termination dates on performance...

Volunteer potatoes are difficult to control in onions and can greatly reduce onion growth and yield. Herbicides and cultivation were evaluated for control of simulated volunteer potatoes in onions in 1996 and 2000. Three interrow cultivations did not control potatoes in the onion row and the remaining plants reduced onion yield 50 and 73% compared with the hand-weeded checks. Three applications...

A study was conducted at Bunda College during the 2003/04 crop season to assess the effect of fertilizer application practices on performance of maize with emphasis on improving the efficiency of using urea as a top dressing fertilizer The treatments were laid out as a split-plot in a randomized complete block design (RCBD) with maize varieties as main plots and fertilizer application practices...

To compare the performance of steer calves managed under different stocking rates (SR; 3.7, 6.2, 8.6, and 11.1 steers/ha for 140 d; chi(I1)) and N fertilization rates (112, 224, and 336 kg of N/ha; chi(I2)) in May 1996, 1997, and 1998, 72 steer calves (BW = 231 +/- 2.5 kg) were assigned randomly to one of 12 0.81-ha dallisgrass (51%)/common bermudagrass (32%) pastures. One-third of the fertiliz...
