BACKGROUND: This study was conducted to investigateeffects of silicate fertilizer application on red pepper(Capsicum annuum L.) productivity with improving soilchemistry under plastic film house in paddy field.
METHODS AND RESULTS: The silicate fertilizer wasapplied as 0, 100, 200, and 300 kg/10a as basal dressingbefore transplanting pepper plant seedlings. Cultivar of thepepper plant was Cheon-Ha-Dae-Se. Amounts of inorganicfertilizer applied as N-P2O5-K2O = 19.0-6.4-10.1 kg/10awas estimated depending on soil test values. After applying50% of nitrogen, 100% of phosphorus, and 60% ofpotassium fertilizers as basal dressing, the seedlings ofpepper plant were transplanted. The rests of nitrogen andpotassium fertilizers were applied as side-dressing after thefirst, second, and fourth harvests of red pepper. Whencomparing selected chemical properties of soils betweenbefore transplanting and after final(the fifth) harvest, soilpH, available P2O5, and exchangeable Ca2+ increased withincreasing the applications of silicate fertilizer, whereaselectrical conductivity(EC) decreased. However, exchangeableK+ was higher with the treatments of 100 and 200 kg/10a,and exchangeable Mg2+ was higher with 300 kg/10aapplication. In addition, nitrogen and phosphorusconcentrations of red pepper collected from the firstharvesting stage decreased with increasing the applicationsof silicate fertilizer, but potassium, calcium, andmagnesium concentrations in red pepper were highest with300 kg/10a application. Yield of red pepper increasedbetween 9.0 and 11.8% with the applications of silicatefertilizer. Marketable fruit rate of res pepper washighest(97.3%) with 200 kg/10a application.
CONCLUSION: The application of silicate fertilizer asbasal dressing in paddy-converted fields improved soilchemistry and increased red pepper productivity.
