Anthracnose caused by Colletotrichum gloeosporioides Penz.) Penz. and Sacc. is one of the most important diseases of mango. The nutritional studies were taken up to know the best source of carbon and nitrogen required for the growth and sporulation of the fungus. The study indicated that out of six different carbon sources tried, mannitol was found to be the best source of carbon for the growth...

This article presents the results of research conducted in desert sandy soils. The study found that humus content soil was moderate upper layer, very low and nitrate form nitrogen, amount mobile phosphorus surface layer soil, 1 m high exchangeable potassium.

Nanoparticles of potassium tantalate (KTaO3) and potassium niobate (KNbO3) were synthesized by oxidation of metallic tantalum in molten potassium nitrate with the addition of potassium hydroxide. Magnetization curves obtained on these ferroelectric nanoparticles exhibit a weak ferromagnetism, while these compounds are nonmagnetic in a bulk. The experimental data are used as a start point for th...

the increasing use of nitrogen fertilizers due to high dynamics of nitrate in the soil would be a serious threat to groundwater, and therefore, to thuman health. this study is aimed to investigate the disperdivity values of nitrate in the coarse, medium and fine sandy soils in the short travel distance of 20, 40 and 80 cm in vitro using the hydrus-1d model. for this purpose, pure potassium nitr...

The Front Cover shows the most active molecule of a series nitrate coumarins, coumarin-7-yl-methyl nitrate, that “magically” releases nitric oxide into bloodstream, leading to vasodilatory effect. Synthesized nitrate−coumarins show potent vasodilator activity on isolated rat aortic rings deprived endothelium, with higher effect those pre-contracted phenylephrine than potassium chloride. This su...

In China, excessive use of nitrogen fertilizers in glasshouses leads to nitrate accumulations in soil and plants, which then limits productivity. Melatonin, an evolutionarily highly conserved molecule, has a wide range of functions in plants. We analyzed the effects of melatonin pretreatment on the growth, mineral nutrition, and nitrogen metabolism in cucumber (Cucumis sativus L. "Jin You No. 1...

If a sartorius muscle of frog is pretreated for 30 min. with a hyposmotic Ringer's (called "hyposmotic potassium chloride") in which all sodium chloride is replaced by 23 mM potassium chloride, and then is immersed in normal Ringer's for about 40 min., a twitch of normal size can be elicited although the potassium contracture is almost completely abolished. During the time that this selective i...

Nitrate is a wide spread contaminant of ground and surface water. The source of nitrate in the ground water may be from run off or seepage from fertilized soil, municipal or industrial waste water, land fills, septic system, urban drainage or decaying plants. Human and animal systems are affected severely on nitrate exposure. The study was to investigate the effect of dietary nitrate exposure o...

Hydrological studies were made for 6 months covering monsoon, summer and transition periods in a reservoir, chiefly to understand the plankton productivity. The physical factors like temperature, light, pH and chemical factors like dissolved O , CO , carbonate, bicarbonate, chloride, nitrate, phosphate, sulphate, calcium, 2 2 magnesium, sodium and potassium were estimated.
