Judul: Pengaruh sekam padi dan TSP pada regosol bercampur abu vulkan galunggung terhadap berbagai ciri fisika, kimia tanah, pertumbuhan dan hasil kedelai (Glycine max L. Merr.)
Abstrak: On Regosol at Sindang Mekar Village, kecamatan. Wanaraja, kabupaten Garut, soybean grown from October 1984 until January 1985 yielded clean weeded and without weed- ings respectively 0.61 and 0.36 tons per hectare. Paddy hulls and TSP added to a 5.9 kilogram Regosol. sample on the yield of soybean was investigated in a greenhouse of Faculty of Agriculture, Padjadjaran Uni- versity with treatments: (1) zero paddy hulls and TSP; (2) zero TSP and 510 g paddy hulls; (3) zero paddy hulls and 10 g TSP per pot; (4) With 510 paddy hulls and 10 gram TSP per pot. No significant yield difference between zero and paddy hulls, on the other hand the zero TSP and Triple Super Phosphate (TSP) yielded respectively 5.98 & and 7.72 8 per pot, with significant difference. A field experiment at Sindang Mekar village, kecamatan. Wanaraja, Kabupaten Garut, on terraced land with a slope gradient of eight percent, and elevation 800 m from sea Level; from January 15 until July 10, 1985 mixed with IFB university tested the effect of hulls and TSP added to Regosol Galunggung volcanic ash on some soil chemical and physical data, and soybean growth and yield. The design is a ran- domized factorial block (RBD) (a) paddy hulls at three levels (zero, 20 and 40 tons paddy hulls per hectare), (b) Triple Super Phosphate at two levels (zero, and 100 kg TSP per hectare, with six replications...dst

Judul: Pengaruh Trass dan Pupuk Fosfor terhadap Pertumbuhan dan Produksi Padi Gogo serta Perubahan Sifat Kimia pada Latosol Gunung Sindur
Abstrak: The high conversion of rice fields to non-agricultural fields have reduced rice production, so it needs the utilization of dry land for paddy cultivation. Latosol is one type of nutrient-poor soils, especially Silica (Si) and phosphorus (P), and generally it is acidic due to further weathering and intensive leaching. This study aimed to determine the effect of Trass and Phosphorus (P) on yield and nutrient uptake of rice plants, as well as changes in the chemical properties of Mount Sindur’s Latosol. This study was a greenhouse experiment conducted in Cikabayan University Farm, Bogor Agricultural University. Soil and plant analysis carried out in the Laboratory of Chemistry and Soil Fertility, Department of Soil Science and Land Resources, Faculty of Agriculture, Bogor Agricultural University. This study took place from October 2012 to April 2013. This experiment used a completely randomized design (CRD) with 2 factors. As the first factor was Trass doses (0 tonnes / ha (T0), 2.37 tonnes / ha (T1), 4.74 tonnes / ha (T2), and 7.11 tons / ha (T3). Second factor was P fertilizer (0 ppm P (P0), 50 ppm P (P1), and 100 ppm (P2). Experiment was repeated 3 times so that there were 36 experimental units. Results showed that there was no interaction effect between Trass and phosphorus in all observed variables. But as a single factor, Trass significantly affect to increase the number of productive tillers in treatment T3 equal to 17.5%, while the increasing amount of soil available-P influence T1, T2, and T3 treatments, respectively for 25%, 62.5, and 149.4%. Further, there was an increase in P-uptake effect on T1, T2, and T3 treatments, respectively for 4.5%, 9.5%, and 24.3%. Moreover, P Fertilizer application was significantly affect the increasing of plant height on P1 and P2 treatments, respectively for 17:45% and 17.6%, number of tillers earnings 3.8% and 20%, biomass weight for 108.4% and 159.7%, and the grain weight for 47.9% and 52.1%, while the increase effect on Si-uptake of P1 and P2 treatments, respectively for 62.07% and 87 %, and decrease the available-Si, respectively for 9.1% and 22.5%.
