ABSTRACT
The experiment to know the effect of fertilizers do- se and kinds of organic fertilizers on yield of sweet corn (Zea mays var. saccharata) has been carried out since 25 June until 3 September 1996 at Kertosari villagge, Pancur- anmas sub district, Secang, Magelang. With the latosol soil type, pH 6,5 and altitude 380 m above sea level.
The method factorial experiment (2x4) with randomized complete block design, consisted of tree replications. The first factor is kinds of organic fertilizers, consisted of: goat stable fertilizers and INRA compos fertilizers. Second factor is fertilizers dose, the consisted of 0, 5, 10 and 15 ton/ha.
The result of the experiment. shows that:
1. The rise of organic fertilizers dose until 10 ton/ha increase volume of cleaned ears per plant, but the rise of organic fertilizers dose 15 ton/ha can increase num- ber of ears per plant, weight of rough ears per plant, weight of cleaned ears per plant, lenght of cleaned ears per plant, fresh weight of straw and dry weight of straw.
2. The rise of INRA compos fertilizers dose increase number of ears per plant, weight of rough ears per plant, weight of cleaned ears per plant, lenght of cleaned ears per
plant, fresh weight of straw and dry weight of straw. 3. Between dose and kind organic fertilizers not other in- fluence for all parameters.
