Potassium nitrate and urea sprays affect flowering and yields of 'Tommy Atkins' (Mangifera indica) mango in Ethiopia

Abstract: The effects of leaf applications of potassium nitrate (KNO3), alone and in combination with urea at different concentrations on flowering, fruit set and fruit quality of Tommy Atkins' mango grown in the rift valley of Ethiopia were evaluated. The trees were characterised by erratic flowering, continuous and high intensity of vegetative growth as well as irregular bearing. Uniform trees were selected for a randomised complete block design experiment with three replications and three trees per plot. Spraying was conducted initially on the immature postharvest flushes and then repeated after the flushes had matured and had dark green leaves. Potassium nitrate concentrations especially in combination with urea (5 litre solution of 4% KNO3+0.5 g urea tree−1 and 5 litres of 4% KNO3+I g urea tree−1) produced better results for most of the flowering and yield parameters. There was a non-significant difference for the qualitative parameters between the treated and non-treated trees. The supplementation of nitrogen...

Effect of Oxidizer on the Combustion Performance of Boron-Based Fuel-Rich Propellant

Abstract: Different boron-based fuel-rich propellants were prepared by replacing part of ammonium perchlorate with different content of cyclotrimethylenetrinitramine, cyclotetramethylenetetranitramine, potassium nitrate, and potassium perchlorate. The burning rate of the propellants under different pressures was measured in the strand burner, the combustion temperature of the propellants under 1 MPa was measured by microthermocouple, and differential scanning calorimetry/thermogravimetric analysis experiments of the propellants in argon atmosphere were carried out. The experimental results show that the effect of each oxidizer on the burning rate of the propellant is different; cyclotetramethylenetetranitramine and cyclotrimethylenetrinitramine could increase the combustion temperature and the gaseous products, whereas potassium nitrate, and potassium perchlorate have the opposite effect. The composition of the combustion products under different pressures was calculated based on the minimization of Gibbs free-ener...

Isobaric Vapor−Liquid Equilibrium for Ethanol + Water + Strontium Nitrate

Abstract: Isobaric vapor−liquid equilibrium for ethanol (1) + water (2) + potassium nitrate (3) at various concentrations of salt and with ethanol mole fractions from 0 to 0.642 has been measured at 100.0 kPa. The results were correlated by assuming that the salt was in ionic form and it was associated only with the water.
