Pengaruh Pemberian Kompos Limbah Jagung Dan Pupuk Fosfor Terhadap Pertumbuhan Dan Produksi Tanaman Jagung Manis (Zea Mays Var Saccharata Sturt.)
This study aims to determine the effect of the interaction of corn waste
compost and phosphorus fertilizer, corn waste compost, phosphorus fertilizer
application, and get a better dose of corn waste compost and phosphorus fertilizer
on the growth and production of sweet corn plants. This research was carried out
experimentally in the field using a factorial randomized block design (RBD),
namely corn waste compost (0, 2.5, 5, and 7.5 tons.ha-1) and phosphorus fertilizer
(200, 300 and 400 kg.ha-1). The parameters observed were plant height, stem
diameter, number of leaves, time appears the female flowers, age of harvest,
weight per cob with cornhusk, production per ha, cob diameter, length of the cob,
weight per cob without cornhusk, number of rows of seeds per cob, and number
seeds per row. The data obtained were statistically analyzed by analysis of
variance and continued with Duncan's New Multiple Range Test (DNMRT) at the
level of 5%. The results showed that there was an interaction of corn waste
compost and phosphorus fertilizer in the production parameters per ha of sweet
corn plants. Corn waste compost can increase plant height, stem diameter, weight
per cob with cornhusk, production per ha, cob diameter, and length of the cob.
The best gave is in the treatment of 7.5 tons.ha-1. The application of phosphorus
fertilizer can increase plant height, stem diameter, time appears the female
flowers, age of harvest, weight per cob with cornhusk, production per ha, cob
diameter, and length of the cob. The best gave is in the treatment of 400 kg.ha-1.
The application of 7.5 tons.ha-1 corn waste compost with 400 kg.ha-1 phosphorus
fertilizer showed better results in almost all parameters, except for the number of
leaves, number of rows of seeds per cob, and number seeds per row.
Keywords: sweet corn, corn waste compost and phosphorus fertilizer
