A systems trial was established to evaluate factorial management practices for organic production of northern highbush blueberry (Vaccinium corymbosum L.). The practices included: flat and raised planting beds; feather meal and fish emulsion fertilizer applied at 29 and 57 kg·ha⁻¹of nitrogen (N); sawdust mulch, compost topped with sawdust mulch (compost + sawdust), or weed mat; and two cultivars, Duke and Liberty. The planting was established in Oct. 2006 and was certified organic in 2008. Weeds were managed by hand-hoeing or pulling in sawdust and weed mat-mulched plots and a combination of hand-pulling, propane-flaming, and post-emergent, targeted applications of acetic acid or lemon grass oil to any weeds present in the compost + sawdust plots depending on year. Data were recorded on input costs and returns in Year 0 (establishment year) through Year 3. Plants were harvested beginning the second year after planting. Planting costs were 741/hahigheronraisedbedsthanontheflat,butthehighercostsweremorethanoffsetbyanaverageof632861/ha. Cumulative net returns after 3 years were negative and ranged from –32,967to–50,352/ha when grown on raised beds and from –34,320to–52,848/ha when grown on flat beds, depending on cultivar, mulch, and fertilizer rate and source. The greatest yields were obtained in plants fertilized with the low rate of fish emulsion or the high rate of feather meal, but fertilizing with fish emulsion by hand cost (materials and labor) as much as 5066/hamorethanfeathermeal.Highercostsofestablishmentandpruningfor‘Liberty’comparedwith‘Duke’wereoffsetbyhighernetreturnsinalltreatmentcombinations,exceptfeathermealfertilizerwitheitherweedmatorcompost+sawdustmulch.Mulchtypeaffectedestablishmentcosts,weedpresence,andweedmanagementcosts,whichincludedproductandlaborcostsforapplicationofherbicides(aceticacidandlemongrassoil)aswellaslaborforhand−weedingasneeded,dependingonthetreatment.Thehighestyieldingtreatmentcombinations(growingonraisedbedsmulchedwithcompost+sawdustandfertilizedwithfishemulsion)improvedcumulativenetreturnsasmuchas19,333/ha over 3 years.This is a scanned version of a published article.
