PEMBERIAN ABU SEKAM PADI DENGAN PUPUK NPK TERHADAP PERTUMBUHAN DAN PRODUKSI TANAMAN JAGUNG MANIS (Zea mays saccharata Sturt) PADA TANAH GAMBUT
Abstract: This research aimed
to study the giving effect of rice husk ash with good NPK fertilizer towards
the growth and production of sweet corn in peat soil. This experiment was
conducted at the experimental farm of the Agriculture Faculty, Rimbo Panjang,
Kampar and carried out in Juni until September 2014. This research was carried
out experimentally using randomized block design (RBD) non factorial consisted
of 6 treatments with 4 repetitions which resulting 24 experimental plots. Each
experimental unit consisted of 24 plants and 6 plants as samples. The
treatments were: AN1: without rice husk ash with NPK 300 kg/ha (135 g/plot),
AN2: rice husk ash 3 ton/ha (1350 g/plot) with NPK 300 kg/ha (135 g/plot), AN3:
rice husk ash 6 ton/ha (2700 g/plot) with NPK 300 kg/ha (135 g/plot), AN4:
without rice husk ash with NPK 600 kg/ha (270 g/plot), AN5: rice husk ash 3
ton/ha (1350 g/plot) with NPK 600 kg/ha (270 g/plot), AN6: rice husk ash 6
ton/ha (2700 g/plot) with NPK 600 kg/ha (270 g/plot). The results of experiment
that was obtained using analysis of variance were tested further with DNMRT (Duncan's New Multiple Range Test) at
the level 5%. Based on the results of this research, the recommended doses are
rice husk ash 3 ton/ha (1350 g/plot) and NPK 600 kg/ha (270 g/plot).
