Resumo: | This study was undertaken to inves gate the effect of two fer liza on levels for grains LFG (N 80 kg; P2O5 50 kg; K2O 70 kg); for silage LFS ( N 160 kg; P2O5 130 kg; K2O 220 kg) upon produc on of fresh mater (FMP) and dry mater (DMP); and the availability of diges ble dry mater (DDMA), total diges ble nutrients (TDNA), crude protein (CPA) and diges ble crude protein (DCPA) per hectare, of two corn cul vars (variety VC; hybrid HC) sown in parcels cons tuted by 6 lines, 7 meters long each. After harvest, the material obtained was homogenized and placed into plas c buckets (18 x 17 cm). Percen le composi on of different parts of the corn plant were determined as well as the total opera onal costs (TOC) of the silages produced. The experimental design was at random in a factorial arrangement 2x2, with four replicates. Signi cant differences were found for FMP among cul vars and fer liza on levels per cul var and for CPA and DCPA among levels of fer liza on. HC has shown beter performance than VC in all produc vity parameters at both fer liza on levels. LFS allowed an increase in produc on of all produc vity parameters per hectare for both cul vars, as well as an increase in stalk par cipa on and a decrease in the par cipa on of corn ear without husks in rela on to the whole plant. For LFG the TOC of produc vity parameters were similar for both cul vars; for LFS, the TOC of DMP, DDMA and TDNA, and especially for CPA and DCPA was greater for VC. |

Após a colheita, o material foi homogeneizado e acondicionado em baldes plásicos (18 x 17 cm). Determinourse também a composiç o percentual das partes da planta e o custo operacional total (COT) de produç o das silagens. O desenho experimental foi ao acaso em arranjo fatorial 2x2, com quatro repeiç es. Foram detectadas diferenças significantes para a PMF entre culivares e entre níveis de adubaç o por culivar e para DPB e DPBD entre níveis de adubaç o. O MH demonstrou melhor desempenho que o MV em todos os parâmetros de produividade, nos dois níveis de adubaç o. O NAS propiciou um aumento das produç es de todos os parâmetros de produividade por hectare nas duas culivares, bem como um aumento da paricipaç o do colmo e um decréscimo da paricipaç o da espiga sem palha em relaç o à planta inteira. No NAG o COT dos parâmetros de produividade foi semelhante nas duas culivares; no NAS o COT de PMS, DMSD e DNDT e, principalmente, de DPB e DPBD foi maior no MV.Departamento de Diagnóstico e Pesquisa Agropecuária.
