ORYZA2000 v.2.13 (November 2009)
Since last official release of ORYZA2000 (version 2.12) in 2004, some additional works have been done from 2004 to 2008. With respect to version 2.12, following changes have been made.
1. Added two extra options for water balance and soil water movement in 2005. These two sub module are called as SAWAH and LOWBAL.
2. In LOWBAL, changes were made in 2005 to separate P and S values (S in and S out).
3. In the input file of experiment description, one variable called as ‘water balance’ was added in that keeps soil water tension at user-defined values.
4. External reading from crop data file for lower air temperature threshold for growth (oC, COLDMIN), and Consecutive number of days below COLDMIN that crop dies (days, COLDEAD).
5. Introduced a maximum development stage after which no more irrigation is given (DVSIMAX) as user defined variable to be read from experiment data file.
6. The calculation rainfall summation in MODELS was relocated from wrong place in ITASK=2 to correct place in ITASK=3.
7. Error corrected in LOWBAL water balance check: +RUNOFC should be +RUNOFCU.
8. In IRRIG routine, we give always irrigation under irrigated conditions, from STTIME onwards, also in seedbed in transplanted systems.
9. Removed setting biomass to zero when drought has led to negative biomass values.
10. New calculations of water parameters:
In ET2 subroutine, calculate ETD, TRC and EVSC always, from STTIME onwards;
For transplanted rice, TRC and EVSC are calculated from emergence onward as well, starting in the seedbed;
In WSTRESS, we calculate TRW now from emergence onward, so also for seedbed in transplanted systems.
11. The following conventions for summations of water balance variables are used now:
CUM1 is summation from STTIME onwards;
CUM2 summation from emergence onwards (in transplanted systems thus includes seedbed);
SUM3 summation from transplanting onwards;
Outputs on water balance of all water balances are positive values for all elements (eg, TRC is positive, rain is positive, percolation is positive, etc.).
12. In ET2, following changes in source code have been made.
!----- 1) From STTIME onwards
ETDCUM1 = INTGRL (ETDCUM1, ETD , DELT)
EVSCCUM1 = INTGRL (EVSCCUM1, EVSC , DELT)
TRCCUM1 = INTGRL (TRCCUM1 , TRC , DELT)
!------ 2) From emergence onward, both in direct-seeded and in transplanted systems
IF (CROPSTA.GE.1) THEN
ETDCUM2 = INTGRL (ETDCUM2, ETD , DELT)
EVSCCUM2 = INTGRL (EVSCCUM2, EVSC , DELT)
TRCCUM2 = INTGRL (TRCCUM2 , TRC , DELT)
END IF
! ------ 3) From transplanting onward, only in transplanted systems
IF ((ESTAB.EQ.'TRANSPLANT'.AND.CROPSTA.GE.3) THEN
ETDCUM3 = INTGRL (ETDCUM3, ETD , DELT)
EVSCCUM3 = INTGRL (EVSCCUM3, EVSC , DELT)
TRCCUM3 = INTGRL (TRCCUM3 , TRC , DELT)
END IF
13. In LOWBAL as well as in PADDY and SAHEL soil water modules, following modifications in source code have been conducted.
!---- Cumulative amounts From STTIME onwards
IRCUM1 = INTGRL (IRCUM1, IR , DELT)
RAINCUM1 = INTGRL (RAINCUM1, RAIN , DELT)
RUNOFCUM1 = INTGRL (RUNOFCUM1, RUNOF , DELT)
EVSWCUM1 = INTGRL (EVSWCUM1, EVSW , DELT)
TRWCUM1 = INTGRL (TRWCUM1 , TRWP , DELT)
PERCCUM1 = INTGRL (PERCCUM1, PERC, DELT)
SSOUTCUM1 = INTGRL (SSOUTCUM1, SS, DELT)
SSINCUM1 = INTGRL (SSINCUM1, SSOILIN, DELT)
DSLR = INTGRL (DSLR , RDSLR , DELT)
!------ from emergence onward, both in direct-seeded and in transplanted systems
IF (CROPSTA.GE.1) THEN
IRCUM2 = INTGRL (IRCUM2, IR , DELT)
RAINCUM2 = INTGRL (RAINCUM2, RAIN , DELT)
RUNOFCUM2 = INTGRL (RUNOFCUM2, RUNOF , DELT)
EVSWCUM2 = INTGRL (EVSWCUM2, EVSW , DELT)
TRWCUM2 = INTGRL (TRWCUM2 , TRWP , DELT)
PERCCUM2 = INTGRL (PERCCUM2, PERC, DELT)
SSOUTCUM2 = INTGRL (SSOUTCUM2, SS, DELT)
SSINCUM2 = INTGRL (SSINCUM2, SSOILIN, DELT)
END IF
!------ From transplanting onward, only in transplanted systems
IF (ESTAB.EQ.'TRANSPLANT'.AND.CROPSTA.GE.3) THEN
IRCUM3 = INTGRL (IRCUM3, IR , DELT)
RAINCUM3 = INTGRL (RAINCUM3, RAIN , DELT)
RUNOFCUM3 = INTGRL (RUNOFCUM3, RUNOF , DELT)
EVSWCUM3 = INTGRL (EVSWCUM3, EVSW , DELT)
TRWCUM3 = INTGRL (TRWCUM3 , TRWP , DELT)
PERCCUM3 = INTGRL (PERCCUM3, PERC, DELT)
SSOUTCUM3 = INTGRL (SSOUTCUM3, SS, DELT)
SSINCUM3 = INTGRL (SSINCUM3, SSOILIN, DELT)
END IF
14. The WSTRESSAEROBIC subroutine has been removed. The drought stress is only calculated in WSTRESS routine.
15. The variable RICETYPE is not available anymore. There is no need for this variable in experiment file.
16. The first version of analysis package, ORYZA_ANALYSIS, for statistical analysis and generation of graphs for all variables with observation values is available in right now. This software is a macro integrated into an Excel spreadsheet named as ‘oryza-analysis(v1).xls’. You can download it freely from our webpage and save it in your target folder. A simple user guide can be found when you open it. It works in Excel version 2003 and higher.
