The present investigation was conducted during two successive, (2014) and (2015) seasons, on Koronaki olive trees of about 15 years old. The trees have been grown in a private farm at Nasr-city, Cairo, Egypt. All the trees in this investigation were similar in growth, healthy, apparently free from disease and the trees were planted at 5x5 meters a part. All the trees received the recommended amount of fertilizers and Irrigation water and the soil at the experimental orchard was classified as sandy in texture.
This study aimed to investigate the suitable pollinizers for Koronaki olive cultivar in effort to increase their production efficiency. Through study the effect of open, self and cross-pollinations by Kalamata pollen grains, Picual pollen grains and Manzanillo pollen grains. Results cleared that cross pollination increase some fruit characteristics such as fruit set %, fruit retention, fruit weight, fruit size, seed weight, pulp weight and oil percentage of Koronaki olive cultivar compared with self-pollination and this increase may be attributed to the effect of cross-pollination in reduce the aborted seed and increase the percent of double seeds fruits. Furthermore, open pollination gave a good resulting increasing the production efficiency of Koronaki olive trees. Which was a wind-pollinated species and generally considered to be self-incompatible also cross-incompatibility exists between some cultivars.
Water is a vital natural resource which is essential for all the activities. Water resources are developed primarily for irrigation, domestic use, power generation and industrial use. In a watershed basin the seasonal modeling of ground water fluctuations is very useful in planning and management of both the surface water and ground water resources. Due to industrialization and urbanization, there is a great demand for water from the recent past. As groundwater is the only major source of water for agricultural and domestic purposes in Vellore district, Water resources, as a while in Vellore district are sustainable but however regional, seasonal and spatial distribution is uneven. Geologically the entire district is underlain by hard rock formations except few isolated patches of sedimentary formation. Hence, it is important to know the effect of geological formations and agricultural/industrial activities on groundwater chemistry. Vellore district is broadly classified into hilly terrains and plain regions. Generally sub–tropical climate prevails over the district. The normal average annual rainfall from four seasons is received. There are approximately 117 well locations in the district. Storage of ground water is dependent on three factors viz Geology, Topography and Climate. Water level responds to monsoon and indicates a steady rise and fall. Water quality is studied based on the ground water samples collected from wells of the Vellore district. Water quality is fluctuated due to large number of tannery units located in Vellore district. The causes and nature of pollution in the river basin is due to the tanneries and industries which determines the impact on application of fertilizers in agricultural fields. Water samples are collected and analysed for specific parameters. The basic water quality elements  PH, TDS, EC, Chloride, Sulphate, Nitrate, Carbonate, Bicarbonate, metal ions, trace elements have been estimated. The salinity level of water is high in the foot hills and river bed areas. There are three major classifications like low, medium, high level of water contamination observed in Vellore district. The highest levels of chemical contamination are found in the eastern part of the region. The contribution of manmade activities to major iron compositions in ground water is limited in comparison to trace metals. Qualitatively, ground water also changes with time and space depending upon Geologic environment and water table fluctuation. The quality of water is generally good in Vellore district except in areas where there is acute pollution due to the discharge of effluents from tanneries into the river alluvial belt. Recommendations for optimum utilization could be made only at the rate of natural replenishment as ground water has become a scarce commodity
A commercial preparation, Oligomate 55NP, was used as a source of galactooligosaccharides for fermentation experiments. The reaction residues of glucose and lactose were removed from it by a fermentation method. This pre-purified preparation was fermented by selected strains of lactobacilli, bifidobacteria and entrerococci for 24 hours. The total amount of galactooligosaccharides, optical density and pH in the media were determined at the beginning and at the end of fermentation. It was possible to conclude from the results achieved that galactooligosaccharides were fermented by all used strains of microorganisms, but with varying intensity. The degree of their utilization correlated well with the increase of microbial counts characterized by the elevated optical density of the substrate at the end of fermentation.
