Target Yield calibration: NO crop_devnotes Population based on 5.0 x 5.0 meter spacing Used 500 days to find annual heat units so that senescence does not occur. It cannot be properly controlled. Date palm leaves live from 3 to 7 years then die and hang down on the tree and in managed groves are trimmed off annually. For a 5 year average, this is a removal rate of 20%, and must be done to get leaf biomass correct. Date palm leaves consist of the Rachis and leaflets. Leaflets have a specific leaf area of 3.8 m^2/kg. assuming the that rachis is 70% of the palm frond mass and contributes little area, the specific leaf area becomes 1.14 m^2 /kg. Mature tree mass (at around 25 years) should be about 1000 kg not counting the root ball, which is about half the weight. Height is about 25 feet. Mass to cover ratio set the same as bananas and plaintains MJK 11-12-2020 Note: the between row cover names do not relect any mechanism in WEPS, so only one orchard, planted crop is available This was tested in Thermal CA with the management rotation: 01/01/01 Residue, row cleaner 01/02/01 Irrigation, Start Monitor (Buried Drip) 01/02/01 Planter, transplanter, no beds, no till 31/12/01 Irrigation, Stop Monitor 01/02/02 Leaf thinning 01/02/02 Irrigation, Start Monitor (Buried Drip) 01/03/02 Fruit thinning 01/06/02 Fruit thinning 01/10/02 Harvest, orchard and nut crops 31/12/02 Irrigation, Stop Monitor Year 2 is repeated until grove refurbishment at 50 years
