【 摘 要 】

Organic and inorganic fertilizer are important for crop productivity. Waxy corn (Zea mays ceratina L) is used under crop-livestock system (CLS) in Indonesia. The characterized of CLS is crop yield for food, stover and corn-husk for livestock feed, cattle dung for manure as organic fertilizer. The quality of manure could be enhanced by adding organic-N (Gliricidea sepium) and organic-P (rock phosphate, guano) at the initial fermentation process that was called manure plus. Present study investigated the effects of organic-NP enriched manure application on plant growth and waxy corn production, stover and corn-husk production in vertisol soil Sragen District, Central Java. The experiment was conducted using a randomized complete block design with seven treatments and four replicates, T1 (inorganic-NPK), T2 (manure), T3 (manure+RP), T4 (manure+guano), T5 (manure + legume), T6 (manure+ RP+legume), and T7 (manure+guano+legume). The results showed that plant height and waxy corn production non-significantly affected by the treatment. Fresh waxy corn stover production and fresh corn-husk production significantly affected by the treatments. Manure plus resulted in similar on fresh waxy corn stover production and fresh corn-husk production compared to inorganic-NP fertilizer. It was concluded that organic-NP enriched manure replaces NPK as inorganic fertilizer.
