Dream team session Alwyn du Preez
◦ Deep well drained soil ◦ 20-35% clay with water holding capacity Is organic matter content important? ◦ It is a benefit, but not compulsory
◦ 1000-1200mm per year ◦ 150 -200mm per month starting Nov to March (nutset-maturity) ◦ 20-50mm per week Would you utilise irrigation? ◦ Yes, especially if it is dry during the flowering period.
◦ At least 100 Ha ◦ One Manager can manage 100 ha in SA. Would it be staged plantings or all in one planting? ◦ All in one, if the weather allows it.
◦ High kernel recovery cultivars ◦ 816, A4 ◦ Cross pollinator cultivar ◦ 741, Daddow, Beaumont? Would you use pollinators? ◦ Yes ◦ 2-3 bee hive per Ha depending on cost for bees
◦ 8m X 4m What row configuration would you plant? (east/west or north/south or on the contour?) ◦ North / South for optimum light interception What is the maximum length per row? ◦ No Limit, the longer the easier to spray if it is flat. ◦ Cross roads every 500m.
◦ Yes, rip soil before planting commencedWould you mound the rows? ◦ Only if the soil is shallow and drainage is a problem(planting shade tolerant grasses?) ◦ No need in SA with labour harvesting
Year 5 production target = (tonnes of SK/ha) ◦ 400Kg – 600Kg Year 10 production target = (tonnes of SK/ha) ◦ 1600kg – 2000kg Year 20 production target = (tonnes of SK/ha) ◦ 1600kg - 2000kg
◦ Start to train trees in year 1 ◦ Encourage central leader and side branches ◦ 816 needs to be pruned to start bearing earlier, they do not tend to make side branches ◦ Limb removal starts from year 5 annually ◦ Pruning program must start early winter. What method would you use? ◦ Limb removal ◦ Cut the rows open ◦ Maintain regrowth removal and management
◦ Tree height maximum 7 meters for effective spray coverage.◦ Plant early flowering and late flowering cultivars separately.◦ Filling points for spray machine must be close and accessible.◦ Harvest weekly
◦ Harvest crop a.s.a.p. when mature and dry/ cure properly for optimum quality.◦ Build proper curing facilities to accommodate the maximum crop volume at any given time.◦ Build a sufficient storage facility.◦ Resorting facilities for NIS between curing and storing bin.◦ Rule 1: Never allow harvesting or pruning to take up valuable hunting and fishing time!
