In sorghum and mungbean – lentil cropping system, field experiments were conducted for three successive years to assess the effect of mung bean residue incorporation on sorghum and succeeding lentil productivity along with different doses of phosphorus (P; 0, 30, 60 kg ha−1) applied to these crops. The level of soil fertility was also tested with or without incorporation of mung bean residue. T...

A field experiment was conducted during rainy seasons of 2007-2009 in India (Manipur) to study the effect of different sources and levels of phosphorus on productivity of soybean [Glycine max (L.) Merrill]. The treatments consisted of four sources of phosphorus [Single super phosphate (SSP), Di-ammonium phosphate (DAP), Single super phosphate (SSP)+Phosphate solubilizing bacteria (PSB), Di-ammo...

The experiment was conducted at the Agronomy Field laboratory, Department of Agronomy and Agricultural Extension, University of Rajshahi to study the yield and yield components of wheat as affected by phosphorus fertilization. The experiment consisted of two factors i.e. (i) three wheat varieties viz., Shatabdi, Bijoy and Prodip and (ii) five levels of phosphorus viz. 0, 30, 60, 90, 120 kg P2O5...

Chemical strengthening of aluminosilicate glasses through K+–Na+ ion exchange has attracted tremendous attentions because of the accelerating demand for high strength and damage resistance glasses. However, a paramount challenge still exists to fabricate glasses with a higher strength and greater depth of ion-exchange layer (DOL). Herein, aluminosilicate glasses with different contents of P2O5 ...

The direct available method for phosphorus in fertilizers, Method 960.03, is an Official Method for extraction of both P2O5 and K2O. Because K2O is much more soluble and easier to extract than P2O5, the conditions of the extraction procedure are set for efficient extraction of P2O5, and the extraction of K2O is, in effect, a bonus. In 1993, a modified extraction procedure, using an extractant o...

Liu G.D., Morgan K., Hogue B., Li Y.C., Sui D. (2015): Improving phosphorus use efficiency for snap bean production by optimizing application. Hort. Sci. (Prague), 42: 94–101. Phosphorus (P) is essential for crop production. Adequate application P rate is critical for enhancing productivity and profitability of snap bean (Phaseolus vulgaris L.). The goal of this study was to optimize P applicat...

Soils generally contain adequate amount of inorganic and organic phosphorous but most of these remain unavailable to plants. The efficiency of water soluble phosphorus alone is usually low and soluble phosphorus when added to soil along with phosphate solubilizing microorganisms indicates utilization. The presence of soil microorganisms capable of transforming insoluble phosphorus to soluble fo...

Chickpea (Cicer arietinum L.) is one of the major legume crops grown in Pakistan having a considerable importance as a food, feed and fodder but due to imbalanced use of fertilizers its production is low. To find the optimum level of Phosphorus and FYM for chickpea and study their effect on agronomic characteristics an experiment was carried out at the Agricultural Research Farm of NWFP Agricul...

Adsorptive removal of dibenzothiophene (DBT) and 4,6-dimethyldibenzothiophene (DMDBT) from model diesel fuel with 20 ppmw total concentration of sulfur was investigated on polymerderived carbons with incorporated heteroatoms of oxygen, sulfur and phosphorus. The materials before and after exposure to model diesel fuel were characterized using adsorption of nitrogen, thermal analysis, potentiome...
