SKRIPSI PENGKAJIAN KETEPATAN DOSIS PUPUK N, P DAN K TERHADAP HASIL TANAMAN JAGUNG (Zea mays, L.) VARIETAS HIBRIDA PIONEER

---

ABSTRACT
An experiment is to study the effect of N, P and K fertilizer dose on yield of corn (Zea mays, L.), had been done since June 4th until October 25th, 2003 in Maduretno Village, Kaliangkrik District, Magelang Regency, Central Java.
The altitude is 750 m, soil kind is andosol and pH is 5,85. The method of experiment is factorial (3x3x3) with completely randomized block design and three replications. The first factor is N dose, 46, 74 and 101 kg N/ha. The second factor is P dose, 0, 14,4 and 28,8 kg P2O5/ha. The third factor is K dose, 120, 180 and 240 kg K₂O/ha.
The result shows that the fertilizing dose until 101 kg N/ha is still able to increase fresh weight of leavy ears. Fertilizing dose until 28,8 kg P₂Os/ha is still able to increases weight of 1000 seed. Increasing dose of K shows the same result on all parameters. The increasing dose until 72,29 kg N/ha at 180 kg K₂O/ha is able to increase weight of 1000 seed. The increasing dose until 10,24 kg P2O5/ha at 180 kg K₂O /ha is able to increase fresh weight of leavy ears. The increasing dose until 11,15 kg P2O5/ha at 180 kg K₂O/ha is able to increase fresh weight of ears without leaves.
