this study was conducted to evaluate the effect of fertilizers on the yield and essential oils of basil. this experiment was carried out in completely randomized block design with three replications in jiroft area. the treatments included three levels of barvar 2 (10, 20 and 25 g/ha), cow manure at three levels (5, 10 and 15 ton/ha), ammonium phosphate and superphosphate triple each at three le...

phosphate solubilizing bacteria are a group of plant growth promoting rhizobacteria (pgpr) that increase growth and yield of plant by enhancing insoluble phosphates. in this study, a greenhouse experiment was carried out to investigate the effect of phosphate solubilizing bacteria and phosphorous fertilizer on the yield and chemical components of sesame. this experiment was conducted in factori...

Wheat (Triticum aestivum L.) was grown in earthen pots containing soil of Balkasar Soil Series (Sandy Loam) in green house at the Department of Soil Science and SWC, Pir Mehr Ali Shah Arid Agriculture University, Rawalpindi during Rabi season, 2007. The Crop was treated with two levels of Phosphorus (40 and 80 kg P ha-1 ) in the form of SSP, TSP, NP and DAP. A basal doze of 100 kg N and 60 kg K...

Long-term phosphorus (P) losses and gains in sandy soils continuously fertilized with either ordinary superphosphate or coastal superphosphate (a granulated mixture of superphosphate, rock phosphate and elemental sulfur) or previously fertilized with superphosphate were investigated under leaching conditions in columns in the laboratory. The soils were subjected to 10 consecutive cycles designe...

Continual application of mineral fertilizer and manures to meet crop production goals has resulted in the buildup of soil P concentrations in many areas. A rainfall simulation study was conducted to evaluate the effect of the application of P sources differing in water-soluble P (WSP) concentration on P transport in runoff from two grassed and one no-till soil (2 m(2) plots). Triple superphosph...

yazd asfordi phosphate rock (pr) was partially acidulated at five levels (0, 40, 60, 80, 100%) for increasing the relative agronomic effectiveness (rae) of canola (brassica napus l.), var. rgs in two calcareous and non-calcareous soils. the partially acidulated phosphate rock (papr) was compared vs. the standard fertilizer (triple superphosphate) in two levels (50 and 100 mg p/kg). this study w...
