SKRIPSI PENGARUH PEMBERIAN DOSIS PUPUK NPK 15-15-15 DAN PUPUK KANDANG TERHADAP PRODUKSI KACANG TANAH (Arachis Hypogaea L.)
ABSTRACT
The experiment entiteled the influence of dose NPK- 15-15-15 fertilizer and manure to the production of ground nut (Arachis hypogaea L) in the sandy soil is performed in April until July 1988 in Desa Lubanglor, Kecamatan Butuh, Purworejo. The experiment was Conducted in the sandy soil recoreer from flooding, with pH 6,5, altitude 10 m. The aim is to know the increasment of production of groundnut with the application of NPK 15-15-15 fertilizer and manure.
The method of the experiment is Split Plot Design, and it was set base on Randomized Completly Block Design with dose of manure as main plot and dose of NPK 15-15-15 fertilizer as sub plot. The first factor is dose of manure consist of 0; 7,5; 15; 22,5 ton/ha. The second factor is dose of NPK 15-15-15 fertilizer consist of 0; 100; 200; 300 kg/ha, with three block as replication.
The result of the experiment show that NPK 15-15-15 fertilizer give significant influence to all parameters result served, while the dose of manure do not give significant influence to all parameters observed. There is not any interaction between manure with NPK 15-15-15 fertilizer, how ever application of manure and NPK 15-15-15 fertilizer together give a trend to increase the production. The highest number of filled pod obtained in treatment of F2 (17,18 fruit/plant), the highest number of unfilled pod in treatment of (1,15 fruit/plant), the highest weight of fresh pod in treatment of F. (28,07 gr/plant), the highest weight of dry pod in treatment F. (18,29 gr/plant), the highest - weight of dry seed in trontment of F. (14,15 gr/plant) and the highest weight of 100 seed in treatment of F (07 gr).
