PENGARUH PEMBERIAN PUPUK KANDANG AYAM DAN PUPUK N TERHADAP PERTUMBUHAN DAN PRODUKSI TANAMAN JAGUNG MANIS (Zea mays L. Var Saccarata Sturt)
Abstract: Sweet corn (Zea mays
L. var Saccarata Sturt) is one type of plant that those fresh harvested and
cultivated in the tropics. In the cultivation of sweet corn there are many
things those need to be addressed such as soil fertility. Attempts to improve
soil fertility can be done by providing organic fertilizer and inorganic
fertilizer. One good organic fertilizer was chicken manure. While inorganic
fertilizers needed include nitrogen (N). This study aimed to determine the
effect of chicken manure and fertilizer N on the growth and yield of sweet corn
(Zea mays L. Var Saccarata Sturt) and to get the best treatments. This research
was conducted at the Experimental Farm, Faculty of Agriculture, University of
Riau, Pekanbaru and held for 3 months ie in January to March 2016. The study
was conducted experimentally using a randomized block design (RCBD) factorial
and three replications. Factor 1: Provision of chicken manure: A1 = 10
tonnes/ha, A2 = 20 tonnes/ha and A3 = 30 tonnes/ha. Factor 2: Fertilizer Urea:
W1 = 100 kg/ha, W2 = 200 kg/ha, W3 = 300 kg/ha and W4 = 400 kg/ha. Combination
of Urea 400 kg/ha with chicken manure 20 ton/ha gave the highestyield in sweet
corn with the the results of 9,153 kg/4,5m2 or equal to 20,340 tonnes/ha
compared with a combination of urea 100 kg/ha with manure chicken 10 tons/ha is
7,321 kg/4,5m2, equivalent to 16,269 tonnes/ha, meaning that the difference has
a 4,071 ton/ha (20,01%).
