The present study was conducted during the two successive seasons, 2017 and 2018, at King Saud University, Saudi Arabia, to investigate effects of foliar sprays on Ziziphus jujuba trees by yeast extract 1% 2% potassium nitrate (KNO3) 2%. All treatments were applied twice (December 15–January 15) in both seasons. Yield fruit quality studied. Treatments significantly improved yield, physical chem...

Using the evaporating method, the solubility of potassium Nitrate was determined in various mixtures containing Water and Ethanol at 25°C. The results show that the solubility of KNo3 decreases with increasing the mass percent of Ethanol in the mixtures. This trend is along with decreasing the dielectric constant of Water+Ethanol mixtures. Moreover, it can be concluded that the totqal solubilit...

to study the effects of priming on seed germination traits of sainfoin 'eski', a factorial in randomized complete block design with three replications was conducted at the laboratory of agricultural research center of sari in 2011. treatments consisted of polyethylene glycol (peg6000) at 5 and 10%, potassium nitrate (kno3) at 5 and 10% and potassium chloride (kcl) at 5 and 10% levels ...

This research was conducted with Biscayne marl soil and Krome gravelly loam from Florida and Quincy fine sand and Warden silt loam from Washington to determine ammonia (NH3) volatilization at various temperature and soil water regimes. Potassium nitrate (KNO3), ammonium nitrate (NH4NO3), ammonium sulfate [(NH4)2SO4], or urea were applied to the soil at a rate of 75 kg N ha . Soil water regime w...

Bermudagrass (Cynodon dactylon) is one of the most frequently-used turfgrasses for golf, sport, and recreational turf throughout tropical, subtropical, and transition zone regions of the world. Recently, a number of seeded bermudagrass cultivars have been released into the turfgrass market and are quickly becoming a popular option for turfgrass managers. A major limitation with these seeded ber...

AIM To compare the plaque inhibition efficacy of a sodium fluoride/potassium nitrate (NaF/KNO3 with 1450 ppm F) test dentifrice to a 0.454% stannous fluoride/sodium hexametaphosphate/sodium fluoride positive control dentifrice (SnF2/SHMP with 1450 ppm F). METHODS AND MATERIALS Twenty-five subjects were randomized to a two-period, two-treatment, double blind crossover sequence using NaF/KNO3 (...

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...

to determine the effects of priming and planting density on improvement of morphological and physiological traits of the two hybrid corns sc (s.c. 704) under double cropping in sari, a split plot experiment as randomized complete block design with four replications was conducted in 2010. treatments included two densities of 80 and 100 thousand plants per hectare as the first factor and osmoprim...

Increasing the nitrate (N) concentration in the rooting substrate above deficiency decreased stomatal conductance and leaf growth rate compared with sufficient N in maize seedlings (Zea mays L.) growing in drying substrate. Novel effects were detected when N in the non-deficient range was supplied directly to the xylem of detached shoots: concentrations above 2.0 mol m-3 KNO3 reduced transpirat...
