Abstract

The problem in patchouli plant cultivation is the reduction of soil?s fertility level which effects on the decreasing of plant growth and yield.  Application of cattle manure is a key to increase the soil?s productivity. The objective of this research is to study the effect of application method and cattle manure dosage on plant growth and yield of patchouli plant. This research was conducted at Lampung Agriculture Polytechnic research?s field in Hajimena Bandar Lampung from December 2010 to March 2011. The experiment was factorial designed (2 X 4 factors) with randomized completely block design with three replications. The first factor was manure cattle application method: spreaded on soil surface or mixed with top soil. The second factor was manure cattle dosage, consist of 0, 10, 20, and 30 ton/ha.  Result showed that (1) the application of manure cattle increased the growth and yield of patchouli plant; the increasing of the dosage would increase plant growth and yield of patchouli plant, (2) Patchouli plant which applied with cattle manure that mixed with top soil has longer primary root, (3) There is no interaction effect between application method and manure cattle dosage on plant growth and yield of patchouli plant.  Key words: application method, cattle manure, growth, yield, Pogostemon cablin

Abstract

To get high quality physic nut seedling one of effort is with vegetative propagation especially with grafting. The objective of this study was to evaluate the effect the maturity of rootstocks and shading rate on the effectiveness of grafting and the growth of seedling of Jatropka. The experiment was conducted in Labuhan Dalam, Subdistrict Tanjung Seneng, the City of Bandar Lampung from January-June 2008. Is a factorial experiment (3X4) with split plot design, shading degrees as main plot consisted without shading, light shading, moderate shading, and heavy shading. Root stock age as subplot consisted 6, 8, and 10 weeks after transplanting. The treatments were consisted 3 replication and each experiment unit consisted 10 seedlings. The result shows that root stock age 8 and 10 weeks produces physic nut seedling growth better than root stock age 6 week. Physic nut seedling without shading and light shading (1 layer paranet) grow better than with moderate shading (2 layers paranet) and heavy shading (3 layers paranet);Key words: Physic nut, root stock age, shading
