Set Up

The experiment was set up on two types of the soil: Mollic Gleysols (FAO, 1998) and Eutric Cambisols where the presence of pathogenic fungi – sugar beet root decay agent – Rhizoctonia solani has been detected since 2005. In a two year study (2008, 2009), the experiment was set up by completely randomized block design in 4 repetitions and 16 different variants. Two beet varieties, Belinda, sensitive to pathogenic fungi R. solani, and Laetitia, tolerant to pathogenic fungi R. solani), were grown. The microbiological preparation BactoFil was applied in different amounts in autumn and spring. In addition, the nitrogen fertilizer application, based on the results of soil analysis, was varied. The following parameters were tested: amount of infected and decayed plants, root yield, sugar content, sugar in molasses and sugar yield. The best results were obtained by applying the microbiological preparation BactoFil, and by 30% reduced nitrogen fertilizer application. Preparation dosage and time of application depended on soil properties.

SUMMARYVarietal and environmental factors which influence test weight were investigated in a field trial with ten varieties of winter wheat and two rates of nitrogen fertilizer. Varietal differences in test weight were correlated positively with the protein content of the grain and inversely with grain yield but they were not related to 1000-grain weight or to flour yield. Variation in test weight associated with varietal and environmental effects in protein content was due to differences in the density of the grain, as measured by displacement of xylene. Separation into density grades within a sample by a flotation method showed a similar relationship with protein content. There were also varietal differences in packing efficiency of the grain. In the case of Maris Huntsman a poor packing efficiency was considered to stem from morphological features of the floret and developing grain which lead to characteristic transverse folds in the ventral surface of the mature grain. For wheat grown in the United Kingdom, test weight may provide a useful guide to flour yield for samples of one variety but it is likely to be misleading for comparisons between varieties.

Randomized Design

A research to study the effects of Zeolite and nitrogen fertilizer application on vegetative growth of maize crop in coastal sandy soil was conducted on the research field of Agriculture Faculty, Muhammadiyah University of Yogyakarta at Tamantirto, Bantul District of Yogyakarta during October until February, 2003. This research was aimed on the study of Zeolite application in order to enhance the nitrogen uptake in the coastal sandy soil, and its effects on vegetative growth of CP I variety of maize. The pot experiment was arranged in 7 x 3 factorial completely randomized design, with 4 replications. The first factor was Zeolite dosage consisted of 7 levels, i.e:  0, 3, 4, 5, 6, 7, and 8 %; and the second one was 3 levels nitrogen fertilizer dosage which consisted of: 75, 110, and 145 kg/ ha. The nitrogen fertilizer was applied on the medium mixed with Zeolite granules. Observations on plant height, stem diemeter, leaves number, plant fresh and dry weight were done during the vegetative growth of maize. The results showed that Zeolite application significantly enhanced the vegetative growth of CPI maize. The 5,2  - 5,6  % Zeolite was optimum to gave the maximum growth of maize crop. Nitrogen fertilizer application was also significantly increased the plant height and biomass weight, and the 145 kg/ha was the optimum dosage. There was no interaction between Zeolite and nitrogen fertilizer application in order to affected the maize growth.
