Effect of Bio-phosphate on Increasing the Phosphorus Availability, the Growth and the Yield of Lowland Rice in Ultisol

Effects of Bio-phosphate on Increasing the Phosphorus Availability, the Growth and the Yield of Lowland Rice in Ultisol (Yafizham and M Abubakar): Ultisol soil is low of macro and micro nutrient, pH and base saturation as well as high toxicity of Al and Fe. To increase productivity of ultisols soils, especially availability of P nutrients, the use of bio-phosphate can increase P solubilizing in the soils. The research was conducted in the green house of Agriculture Faculty, the University of Lampung from January to March 2005. A factorial experiment using two factors in a randomized completely block design with five replications was conducted. The first factor was dosages of bio-phosphate (0; 10; 20 g L-1), the second factor was lowland rice cultivar (Ciherang, Sintanur, Cilosari and IR64). The results showed that the availability of N, K and P nutrients in the soil before planting was low. Application of biophosphate increased availability of N, K and P in the soil. Application of 10 g L-1 and 20 g L-1 of bio-phosphate increased root length of lowland rice, there were 13.3% and 36.8%, respectively. Application of 20 g L-1 of biophosphate increased 100 grain weight of lowland rice which were higher 11.4% compared to without any bio-phosphate

GROUP COMMUNICATION INCREASES STUDENTS' LEARNING MOTIVATION ONLINE

This study attempts to determine the impact of group communication generated at IPB Bogor on IPB students' learning motivation. Group communication was the independent variable in this study, whereas learning motivation was the dependent variable. Indicators of social connection function, educational function, persuasive function, problem solving and decision-making function, and therapeutic function are used to measure group communication variables. Intrinsic elements, such as interests, ambitions, and individual circumstances, are measured, as are extrinsic influences, such as worry about punishment, rewards, and praise, the involvement of parents, teacher wars, and environmental conditions. From April to May 2021, the research was conducted at Bogor Agricultural Institute for Bachelor and Vocational Programs. As it studies influences, the research method employed in this study is a quantitative approach utilizing explanatory questionnaires. The study's sample consisted of 100 persons chosen at random from a total of 22,744 people who met the sample criteria. Non Probability Sampling, often known as Accidental Sampling, is the sampling approach employed. Data analysis in the form of simple regression analysis is used in this study. The results of the questionnaires for each indication of group communication and enthusiasm to learn are summarized in 30 statements. According to the findings of this study, group communication has a significant impact on student learning motivation. 

Distribution of 226Ra Radionuclide in Upwelling Event Off Ulsan, Gampo and Pohang, Korea

Upwelling is an important event in the sea for it makes the area to become more productive. The objective of this study is to determine the distribution of radium-226 as radiotoxic in the upwelling area in the summer season. Measurements of the horizontal and vertical activities of 226Ra in the Ulsan, Gampo and Pohang waters were conducted in June, August 1999 and June 2000 when the upwelling event was expected to occur. Water temperature, salinity and dissolved oxygen (DO) were also measured concurrently. The thermocline layer or the layer where the temperature decreased drastically occurred at a depth between 30 m to 100 m for samples dated June 1999 and 30 m to more than 100 m for samples dated August 1999 and June 2000. The salinity decreased with depth but the DO concentration increased in this layer. The condition affected the vertical distribution of 226Ra in the study area, where the 226Ra activities showed to be relatively homogeneous vertically in each station. This indicates that the upwelling which occurred in the study area was capable to distribute the 226Ra activities from the bottom to the surface. Thus, the 226Ra distribution at that time did not increase with depth, opposite to what usually occurs in the ocean at normal condition. The 226Ra activities also did not decrease after elapsed time of one year, in fact, it increased. However, horizontally the 226Ra activities decreased with increasing distance from the coastal zone. Based on these results, it can be concluded that the upwelling event in the Ulsan, Gampo and Pohang was effective for increasing the 226Ra activities and was capable to create homogeneous 226Ra activities from the bottom to the surface in the water column, and the source of 226Ra was likely to originate from outside area (i.e. coastal zone) and bottom area.Received: 25 March 2009; Revised: 24 August 2009; Accepted: 30 September 200
