Abstract
Most developing areal for peanut crop (Arachis hoypogeae) is upland, that is dominated by parent soil and has acid
characteristis. Main constraints for this soil are pH and low soil productivity. Dolomite plus is a dolomite ameliorant,
with phosphate nutrient. The dolomite plus beside as the ameliorant and a source of magnecium and calcium
nutrients, also as a source of phosphate nutrient. The objective of the research was to study effectivity of dolomite
plus on peanut growth in Inceptisols soil. This research was conducted in the greenhouse using a randomize
completely designed with 8 treatments and 5 replications. The treatments were control, NPK, and combinations of
NPK with six dolomite plus levels. Relative Agronomic Effectiveness (RAE) analyses was used determine to the
effectivity of dolomite plus. The result showed that application of dolomite plus 1,600 kg ha-1 with NPK fertilizer
increased dry weight of grain yield untill 27% (11.53 to 14.65 g plant-1) compared to NPK fertilizer application alone,
that was showed by RAE > 100% or among 171-251%. Application of dolomite plus with NPK increased soil pH, soil
available P (Bray 1), Ca and Mg exchangeable, and CEC as 1.9 unit; 6.2 mg kg-1; 15.87 cmol(+) kg-1; 14.27 cmol(+)
kg-1; and 17.29 cmol(+) kg-1 respectively. Maximum rate of dolomite plus was 2,500 kg ha-1 with the yield was 14.2 g
plant-1 grain dry weight. The rate of dolomite plus that was higher than 2,500 kg ha-1 could decrease the yield
