(units: g/g)Ĭurrent Julian date as a radian fraction of 1 year for soil temperature caculations Weight of seed which can be made from one gram of protein, if the protein is used to supply energy and carbon skeletons as well as protein for the seed. Gram of seed made from one gram of protein remobilized from other plant tissues. Units of glucose required to produce one unit of total plant dry weight. (units: g CH20/g tissue)Īmount of irrigation applied, if fixed, for automatic irrigation (units: mm) (units: g CH2O/g dry weight)Ĭarbon requirement to form one gram of vegetative tissue including the cost to synthesize amino-acids (or proteins?). Units of glucose required to produce one g of dry weight of vegetative tissue.

(units: g CH20/g tissue)Ĭarbon requirement to form one gram of vegetative tissue, without considering the cost of amino-acid synthesis. (units: )Ĭarbon requirement to produce one gram of stem tissue, without considering cost of amino acid synthesis. Units of glucose required to produce one unit of stem. Grams of carbohydrate required to synthesize one gram of shell tissue (Does not include nitrogen). Units of glucose required to produce one unit of shell. (units: )Ĭarbohydrates required to make seed from nitrate. Units of glucose required to produce one unit of seed when protein is available through mining. Units of glucose required to produce one unit of seed when protein must be made from scratch. The grams CH2O required to synthesize 1g of seed and not including seed nitrogen (protein?) (units: g CH2O/g seed tissue) (units: )Ĭarbon requirement to produce one gram of root tissue, without considering cost of amino acid synthesis. Units of glucose required to produce one unit of root tissue. (units: )Ĭarbon requirement to produce one gram of leaf tissue, without considering cost of amino acid synthesis. Units of glucose required to produce one unit of leaf tissue. Reduction in photosynthesis which is correlated to a decrease in % nitrogen in the leaves (Boote, 1976). Shell growth, intermediate variable only, mass/cohort/m 2 (Starting with oldest) (units: g/m 2)Īctual reduction ratio for addition of flowers for a given cohort determined from RFLWAB, photothermal accumulator (TDUMX2) and pegging zone soil water (SWADD2), latter for peanut only. (units: )Įxtractable (available) soil water content in the fruiting zone. (units: )ĭepth of incorporation, weed control op. (units: )ĭate of chemical application, operation (units: d)Īmount of active ingredient applied. Maximum proportion of total development from beginning of pod addition (NPOD0) to normal end of pod addition (NDSET) which can be completed in one night if temperature is optimum and the night time accumulator is accumulating at its maximum rate (night length is above optimum (TNLG0)), (currently not used in PNUTGRO).

(units: )Ĭumulative fraction of development from beginning bloom (R1) to day on which maximum number of V-stages occurs (NDLEAF) completed to date - vegetative partitioning is a function of this accumulator (goes from 0 to 1). Used after NDSET to reduce potential pod addition rate to zero by maturity. (units: )įraction of physiological time completed today from NDSET (normal end of pod addition if optimum conditions) to R8 physiological maturity. Ratio of proportion of development from beginning of pod addition (NPOD0) to normal end of pod addition (NDSET) completed tonight to maximum possible proportion completed (ACCSTD) (not used in PNUTGRO). Logical variable to check if maximum temperature has been changed without changing minimum temperature or vice versa. Zero to unity factor for relative nitrification rate.
