SKRIPSI PENGARUH DOSIS PUPUK OST TERHADAP HASIL BEBERAPA VARIETAS TANAMAN KEDELAI (GLYCINE MAX (L). MERILL
The research of the effect of dosages OST fertilizer to the variety of plant of soy bean (Glycine max L. Merrill) to three varieties are of Wilis, Tidar and Merbabu, the treat- ment of dosages OST fertilizer, there were non fertilizer, 23, 46 and 69 gram/ polybag.
The research was carried out at Kedungsari village, Ma- gelang subdistrict, Magelang regency, Central Java Province. The altidute about 380 meter above sea level, the soil type on latosol, pH 6-6,5.
The method utilized was Factorial with Split Plot Design (SPD) based on Completly Randomized Design (CRD) variety as Main Plot and dosages OST fertilizer to Sub Plot and there were replicated three levels of variety.
Main Plot which consist of three levels variety of Wilis, (V₁), Tidar (V2) and Merbabu (V3).
Sub Plot which consist of four levels non treatment (0), dosages fertilizer 23 g/ polybag (01), 46 g/ polybag (02) and 69 g/ polybag (03).
The result of the experiment analysis show
1. The variety treatment doens't give any significant effect on the height of plant, number of fertile modes, number of uni- filled pods, fresh weight of straw, dry weight of seed, weight of 100 seeds and dry weight of straw, but the variety gives very significant effect on the number unfilled pods, the highest yield was reached on (V202) 62,8 and the lo- west yield was reached on (V10): 34,1.
2. OST fertilizer treatment doesn't give any significant effect on the height of plant, number of filled pods, number of fertile nodes, fresh weight of straw, but gives very signi- ficant effect on the number of unifilled pods, the highest yield was reached on (V303): 2,66 and the lowest yield was reached on (V201): 0,55 and dry weight of seeds, the hig- hest yield was reached on (V103): 9,70 g and the lowest
yield was reached on (V,0): 7,16 g. 3. There is no interaction between all parameters observed is not found.
