Pengaruh Pemberian Mulsa Chromolaena odorata (L.) Kings and Robins pada Kandungan Mineral P dan N Tanah Latosol dan Produktivitas Hijauan Jagung (Zea mays L.)
Abstract: Corn is used as
foodstuff and industrially utilized feed as a potential ingredient in animal
ration. Green forage, baby corn and its cobs are used also as ruminants feed.
Application of Chromolaena odorata on latosol as mulch material is expected to
improve corn production by contributing organic nutrition. The objectives of
this research were to recognize the effect of Chromolaena odorata on production
and quality of green forage of high density corn, and to observe the
contribution of phosphorous mineral from decomposition of Chromolaena odorata
in the ground. This research was divided into two steps of experiment. The
first experiment, consisted of two levels of treatments, i.e.: with and without
Chromolaena odorata (12 ton/ha). The plants were fertilized with 60 kg K/ha and
225 kg N/ha. Plant was harvested at 40 days after planting. In the second
experiment, corns were cultivated in the same area and the application of mulch
(12 ton/ha) and P (60 kg/ha). Mulch increased significantly vertical height but
there was no effect on production of green forage, mineral content in crop and
uptake of P and N. In the second experiment, mulch addition improved vertical
height of the crop, fresh and dry weight of green forage, content of P and N on
the tissues of crop and also uptake of P and N between two treatments were not
significant. Application of Chromolaena odorata mulch (2x12 ton/ha) was similar
as the addition of P anorganic (60 kg/ha) in improving growth, production and
quality of green forage of corn. In this research, the mulch improved the
content of mineral P and N in the soil.
