TL;DR: For the past several years the writer has been employing boron as one of the elements of which traces have been added to the culture solution for the successful growth of citrus plants in water and sand cultures.
Abstract: Although small amounts of boron are injurious to citrus species,2 the presence of still smaller amounts may be harmless and even essential for their healthy growth. While boron has been shown by many investigators to be an essential constituent of a rather large and increasing number of plants, it has not previously been shown to be so for citrus. For the past several years the writer has been employing boron as one of the elements of which traces have been added to the culture solution for the successful growth of citrus plants in water and sand cultures. The culture solution was made up from the following salts: sodium chloride, magnesium sulphate, potassium nitrate, calcium nitrate, potassium acid phosphate, and ferric tartrate. The composition of the culture solution expressed as parts per million was as follows: NA K CA MG FE NO, CL SO4 PO, TOTAL

TL;DR: In this article, the catalytic oxidation of benzyl halides to aldehydes and ketones in aqueous media was studied under relatively mild reaction conditions by using phase-transfer catalyst combined with potassium nitrate and 10% aqueously potassium hydroxide solution.

TL;DR: Rhizoctonia solani caused maximum mortality of mung bean seedlings at 20°C, and the disease incidence decreased with increase of temperature; 30° was optimum for mycelial growth of the fungusin vitro.
Abstract: Rhizoctonia solani caused maximum mortality of mung bean seedlings at 20°C, and the disease incidence decreased with increase of temperature; 30° was optimum for mycelial growth of the fungusin vitro. The fungus grew best in nutrient broth of pH 5.5 but infected mung bean and pea seedlings more severely in neutral and alkaline river sand than in the sand adjusted to acidic reaction. The disease incidence was higher in adequately moist sandy loam and less in soil under moisture stress. Incidence of cowpea seedling rot was higher in heavy-textured loam and silt loam soils than in light-textured sandy- and loamy sand. Addition of montmorillonite and kaolinite in the sandy soil increased the disease incidence, but these clays reduced fungus growth in culture. More seedling rot occurred in the sandy soil fertilized with urea, potassium nitrate, monocalcium phosphate, or potassium dihydrogen phosphate while soil application of ammonium nitrate, potassium chloride, or potassium sulphate decreased the disease. In tests with combined soil application of N (as urea), P (as monocalcium phosphate) and K (as potassium chloride), disease incidence was more in all combinations having P. Among the six micronutrients tested, only boron reduced the disease incidence significantly both in presence and absence of NPK fertilizers. Farm-yard manure and biogas sludge aggravated seedling rot but their water extracts decreased it. Humic acid, extracted from farm-yard manure, increased the disease incidence but was inhibitory to fungus growth in culture. Green manure also resulted in more disease.

TL;DR: Barley seedlings grown at different levels of KNO 3 were infested with aphids and it is suggested that nitrate fertilization may affect aphid performance on barley seedlings because it causes changes in gramine concentration in the leaves.

TL;DR: In this article, a method for manufacturing chemically reinforced glass, including a step for bringing glass including sodium into contact with an inorganic salt including potassium nitrate, thereby performing ion exchange between Na in the glass and K in the ionized salt, was presented.
Abstract: A method for manufacturing chemically reinforced glass, including a step for bringing glass including sodium into contact with an inorganic salt including potassium nitrate, thereby performing ion exchange between Na in the glass and K in the inorganic salt, the method for manufacturing chemically reinforced glass wherein the inorganic salt includes at least one species of salt selected from the group consisting of K2CO3, Na2CO3, KHCO3, NaHCO3, K3PO4, Na3PO4, K2SO4, Na2SO4, KOH, and NaOH, and the method includes a step for cleaning the glass after the ion exchange, a step for acid-treating the glass after the cleaning, and a step for alkali-treating the glass after the acid treatment.
