English. Two green house pot experiments have been carried out at Center for the Application of Isotopes and Radiation, Jakarta to study the effect of irradiated sludge applied on corn grown at latosol soil of Pasar Jumat, Jakarta. Result of these experiments showed that irradiated sludge in a rate of 5 ton/ha was able to increase dry matter production and P uptake. Application of 5 ton/ha of irradiated sludge had the same effect with 90 kg P2O/ha of TSP observed from dry matter production, total P, and fertilizer P uptake, but its effect was still lower than 5 tons/ha of chicken manure application, especially observed from total P uptake.

Dua buah percobaan pot telah dilakukan di rumah kaca Pusat Aplikasi Isotop dan Radiasi, Jakarta untuk mempelajari pengaruh pemupukan sludge radiasi pada tanaman jagung di tanah latosol Pasar Jumat, Jakarta. Hasil percobaan menyatakan bahwa pemupukan sludge radiasi dengan takaran 5 ton/ha dapat menaikkan bobot kering tanaman dan serapan P. Pemberian 5 ton/ha sludge radiasi mempunyai pengaruh sama dengan pemberian 90 kg P2O5/ha TSP, dilihat dari produksi bobot kering tanaman, serapan P total, dan serapan P pupuk, akan tetapi dibandingkan dengan pemberian 5 ton/ha kotoran kandang ayam, pengaruhnya masih lebih rendah terutama bila dilihat dari serapan P total tanaman.
