Abstract

The study on growth production of paddy (Oryza sativa L.) Variety IR-64 in the peat soil given Dolomite andCopper (Cu) through leaves have been conducted at Simpang Baru Village Tampan, Pekanbaru City for 5bohths; starting from February to June 2003. The objective of the experiment was identity the effect ofbolomite and Copper given trough leaves and their interaction on the growth and pnKiuction of Rice in the peatisoil.
