Effect of Fermened Cake on Nutrients and Quality of Potato
The effect of fermented cake on nutrients and quality of potato in sandy soil was studied.The results showed that fermented cake could enhance accumulation of nitrogen and potassium in plants,compared to the traditional fertility,the yield could increase by 8.16%～24.47%,the starch content could reach 14%～16%.It indicated that the fermented cake had the function of increasing the yield and quality of potato.
The present study aimed to analysis the aftermath of science learning based on an integrated scientific approach to local potential, onion agriculture, towards the science process skill of 7th grade of junior high school students. The study was a quasi-experimental research with non-equivalent control group design. The object of this experiment was all classes in the 7th grade of Wedarijaksa 2 junior high school. Cluster random sampling was used to gather the sample, as the result, two over seven classes were randomly chosen. Data that be used in the research were the result of science process skill test. Data were analyzed using One-way Anova. The result shows that there is a significant impact of science learning based on scientific approach to local potential, in this case is onion agriculture, towards process science skill of the students.
