PENGARUH PUPUK KANDANG AYAM DAN N, P, K TERHADAP PERTUMBUHAN DAN PRODUKSI JAGUNG MANIS (Zea mays saccharata Sturt) DI TANAH ULTISOL
Abstract: Giving chicken
manure fertilizer and N, P, K done to improve the growth and production of
sweet corn in ultisol soil.This research aims to obtain interaction of various
doses of chicken manure fertilizer and N, P, K the best on the growth and
production of sweet corn in ultisol soil. This research was carried out in
society garden at Indra Puri, Tenayan Raya District, Pekanbaru in September to
December 2013. This research used Randomized Block Design (RBD). The treatment
consist of2 factors, factor I: without chicken manure fertilizer, 46,8g/plant
chicken manure fertilizer, 70,3g/plant chicken manure fertilizer, 93,7g/plant
chicken manure fertilizer and factor II: without giving N, P and K, 9,14g/plant
ZA, 6,25g/plant TSP, 0,14g/plant KCl, 13,7g/plant ZA, 9,79g/plant TSP,
0,21g/plant KCl, 18,2g/plant ZA, 13g/plant TSP, 0,29g/plant KCl. Data were
analyzed using ANOVA and further tested by Duncan's Multiple test at 5% level.
Parameters measured were the plant height(cm), cob diameter (mm), Male flowers
appear time (DAP), female flowers appears time (DAP), heavy cob with husk(g),
heavy cob without husk (g) and plants dry weight. The results of research shows
the interaction of chicken manure fertilizer and N, P, K had no effect on all parameters except on cob
diameter and plants dry weight. Combination treatment of chicken manure
fertilizer with N, P, K can improve sweet corn growth, while the increase of
sweet corn production occurred at doses 46,8 g/plant chicken manure fertilizer
and ZA 13,7 g/plant, TSP 9,79 g/plant, KCl 0,21 g/plant.
