Intercropping, which grows at least two crop species on the same pieces of land at the same time, can increase grain yields greatly. Legume-grass intercrops are known to overyield because of legume nitrogen fixation. However, many agricultural soils are deficient in phosphorus. Here we show that a new mechanism of overyielding, in which phosphorus mobilized by one crop species increases the gro...

Oligoribonucleotides have been synthesized directly from unprotected ribonucleosides by a chemical polymerization approach using phosphorus tris-azoles. The procedure involves two steps: (i) the reaction of unprotected ribonucleoside with phosphorus tris-azole and (ii) the in situ oxidation of the resulting phosphite with iodine and water. Several phosphorus tris-azoles were investigated for ge...

The hybrids are responsive to phosphorus application, have high use efficiency and can produce mean yields in environments with low phosphorus. PE of these is high, therefore they recommended for cultivation the North Northwest regions Rio de Janeiro State, Brazil.

• Median total phosphorus concentrations for the period 1984-93 were less than 0.1 milligrams per liter at 65 of the 83 stations evaluated in the study unit. • Highest total phosphorus concentrations were in the Hiwassee River Basin (near 2.0 milligrams per liter) and at West Chickamauga Creek near Chattanooga (1.45 milligrams per liter). • Total phosphorus concentrations have not significantly...

The article provides research on the study of norms nitrogen-phosphorus fertilizers yield soybeans and masha in conditions gray-brown soils. use mineral has had a significant impact formation soybean mash yields. Yields grains, depending variants experience, range from 15.8 to 27.6 c/ha, mush - 13.0- 24.1 cents per hectare.

The production of ribonucleic acid (RNA)-depolymerase-forming 5'-nucleotides (5'-nuclease) was investigated with the fungus Aspergillus quercinus in media containing 68, 10, 5, 3, 1, and 0.5 mg of phosphorus per 100 ml. Yields were maximal with 5 mg of phosphorus per 100 ml. RNA-depolymerase-forming 3'-nucleosides (3'nuclease) and phosphomonoesterase were maximal in media containing 1 and 0.5 m...
