Abstract

pot trial about residue effects of compost and comrnercial fenilizer on Chernical Characteristics of Regosol and Production of Baby Corn for the second planting time. This research was condu.f,o at Greenhouse of Agriculture Faculty and P3lN Laboratory, Andalas University from August to December 2006. Lettuce was the first plant planted on the pot' then it was continued with Baby Corn. This experiment was arranged based on 3x5 Factorial Randomized design with three replications. The first factor was compost; 0 ton/ha' 5 ton/ha, and l0 ton/ha. The second factor was commercial fertilizer: 0o ,25o , Sooh,75o/o, and 100% of recommendation. Based on the research, it was found that the residue of residue interaction with fertilizer influenced to the growth and yield of Baby corn for the second planting time. From the statistical analysis of thE result, it cwas concluded that 5 ton compost/ha (20g c_ompost/pot) was able to increlse the chemical charesteristics of Regosol, they were pH H2O, KTK, C- organic and N-total. Whereas for pH KCL, the available-P and basic cations. its valueable mez*ure was started from 5 ton/ha ( zoglpot;. For the analysis of plant in the concentration of N and p, it was taken from the treatment of 4 ton/ha (40 g/pot) by using 100 % fertilizer' Key word ; The Residue Effect of Mantre
