Bitange N M. email@example.com ABSTRACT The effect of varying rates of organic Rutuba and inorganic NPK fertilizers on the soil chemical properties, growth, yield and nutrient use efficiencies of clonal tea (Camellia Sinensis) was studied. The treatments comprised: control (no fertilizer), 625 kg NPK/ha, 937.5 kg NPK/ha, 1875 kg NPK/ha, 625 kg Rutuba/ha + 625 kg NPK/ha,

The process of transpiration also help the plant to cool down. There are many environmental conditions that affect the opening and closing of stomata and thus affect the rate of transpiration. For example Temperature, light intensity, air currents, and humidity are some of the environmental factors that affect the rate of
GRAVIMETRIC DETERMINATION OF MOISTURE AND PHOSPHORUS IN FERTILIZER SAMPLES Magdato, K. C. , Balbuena, J. S. Institute of Chemistry, University of the Philippines, Diliman Quezon City Date Performed: August 27, 29 and September 3, 2014 Date Submitted: September 10, 2014 Abstract The experiment aims to use gravimetric method of analysis in determining the moisture and phosphorus content in a fertilizer sample which is important in plant growth. The procedure included constant weighing of the crucible and sample. The addition of ammonia and magnesium sulfate heptahydrate caused the formation of the precipitate identified as magnesium ammonium phosphate hexahydrate(MgNH4PO46H2O). The weight of the precipitate was used to determine the mass of
Metabolism of livestock species is affected by ambient temperature rise and humidity levels. The magnitude of response depends upon species, breed and physical environment factors. The rectal temperature has been considered as an index of thermal balance of animal. The increase in body temperature of animals may be to an extent of 1-2 °C during normal diurnal variations and 4-5 °C during thermal exposure/work in heat. Increase in body temperature over a hot day has been considered a test of adaptability and gross deviation has been attributed to poor adaptation (Rhoad, 1944).
A comparison of the plantlets growth in two different humidity level shown that the low humidity environment enhance the evaporation of plantlets compared to the high humidity environment. The humidity of the internal air in a culture vessel is also affected by the irradiance as well as the water content of the medium. The humidity also can be affected due to the presence of light. It can be seen that during light period, the air humidity is decreased and the tension of the medium increase while during dark period, the air humidity is a bit high causing the tension of the medium to increase causing more water to flow out from the medium and disturb the growth of the plantlets. The relationship between the relative air humidity and evaporation can be conclude that as the air humidity level is low, the rate of evaporation is high.
These include process and storage conditions (frozen or sterilization temperatures), gaseous environment, such as vacuum packaging with high CO2 and low O2 concentrations, and relative humidity (Lund et al. 2000). The relative humidity and gaseous condition of storage, respectively, influence the aW and Eh of the food (Ray & Bhunia, 2008). Ray & Bhunia (2008) also added that microbial growth is accomplished through enzymatic reactions. It is well known that within a certain range, with every 10oC rise in temperature, the catalytic rate of an enzyme doubles.

However the most determining water state influencing physical properties, chemical reactions as well microbial growth in food is the free water (Labuza, 1980). Scott (1957) used terminology of water activity which was equivalence to the equilibrium relative humidity to describe the amount of available water in food required for chemical reactions and microbial growth.
