Le sugiero que busque en tutoriales de excel

Well, it has been working for everybody for more than 7 years. I'm only responsible for the tutorial I produced, not for the program

@@FranciscoVillalobos thank you for your reply sir

Ok muchas gracias!​@@FranciscoVillalobos

I don't know what you mean

Villalobos, F.J., Testi, L., Orgaz, F., García-Tejera, O., Lopez-Bernal, A., González-Dugo, M.V., Ballester-Lurbe, C., Castel, J.R., Alarcón-Cabañero, J.J., Nicolás-Nicolás, E. and Girona, J., 2013. Modelling canopy conductance and transpiration of fruit trees in Mediterranean areas: a simplified approach. Agricultural and forest meteorology, 171, pp.93-103.

I don't understand your question

If you have the same results, that means that all the treatments are the same. Revise them and check that they are correctly defined

take into account that for each kg of water an energy of 2.45 MJ is spent. Now W/m2 is J/s/m2 and mm is L/m2 ...

For doubts on the use of AquaCrop you should contact the authors of the program

@@FranciscoVillalobos no i need help to learn this model

For that also you should contact the authors of the program.

You can use a weather generator for additional data, like our ClimaSG

@@FranciscoVillalobos I have weather and all the necessary data but how can I run for future yield simulation 2040 - 2070?

@@gebremariamadane1897 If you want to simulate with future weather you need to generate it. Use a weather generator like ClimaSG. You need to know how much the temperature will change in that period as compared to the present

@@FranciscoVillalobos please can i have your email address?

Gracias. Muy amable

If you have specific questions you may use [email protected]

Calibration refer to parameters in models, not to models. Performing calibration will depend on the specific parameter that we're dealing with. We can work with the programs included in DSSAT. See the tutorials in my YT channel

The method is descrobed in the supplementary materials of doi.org/10.3389/fpls.2018.00632

@@FranciscoVillalobos Thank you very much.

No sé a qué se refiere. He usado el programa normal

To work with these additional parameters you need to use a text editor to change the line of automatic irrigation @N IRRIGATION IMDEP ITHRL ITHRU IRON IMETH IRAMT IREFF AVWAT IFREQ AIName 1 IR 100 -99 100 GS007 IR004 -99 1 -99 3 Sowing date

Thanks for the tip. In fact, the problem was a bug in the ET calculation. Now it is solved (hopefuly). Download the new excel

Thank you for your immediate answer!

Weather data have been taken from www.juntadeandalucia.es/agriculturaypesca/ifapa/riaweb/web/inicio_estaciones

Es un parámetro característico de cada superficie. Ver Villalobos & Fereres, 2016, chapter 3

0,23 de albedo corresponde, aproximadamente, al que daría una superficie de pasto de 12 cm de altura cubriendo el 100% del suelo, que es el cultivo de referencia que define la ET0. Por lo tanto, en el contexto de este cálculo, sí es una constante.

La productividad y la ET de cultivos como el arroz es relativamente insensible a la densidad de plantas por encima de un valor umbral, es decir, el modelo debería producir lo mismo a partir de 200. Sugiero que uses ese valor. De todas formas si estás interesado en respuesta a la densidad deberías probar Ceres-Rice, que está incluído en el paquete DSSAT, completamente gratuito, y es realmente un modelo de simulación de arroz que responde a agua y nitrógeno

If you know the composition of the solution that you want for that crop, then it's straightforward. If you don't know it, you should find out elsewhere

maybe you have not updated the list files

@@FranciscoVillalobos thank you. I'm new to DSSAT. How is updating done?

Goto File > Update LST files, etc..

@@FranciscoVillalobos Thank you. It's running now

www.uco.es/fitotecnia/fertilicalc_4.html

No, sorry

@@FranciscoVillalobos , You are good teacher

hi! the link is no longer working. would u share with me the excel file?

I have tried and it says: "The server is temporarily unable to service your request. Please try again later." Be patient and try later. If still it does not work then contact the authors

If the format is the same then it should work

Si se refiere a cálculo de soluciones madre para fertirriego tenemos FertiliCalc-Fertigate-NPK

I don't know what you're looking for. Our program is FertiliCalc

In this case I got the data from the network of Junta de Andalucia (www.juntadeandalucia.es/agriculturaypesca/ifapa/riaweb/web/inicio_estaciones)

@@FranciscoVillalobos thanks a lot

Not exactly. The difference is in the calculation of long wave radiation. However, the results should be quite close

@@FranciscoVillalobos Dear Francisco thank you for answering. I hope you are fine. It is expressed in w/m2; if I want to find in mm/d should I multiple LE by 0.035?

@@cayansabahattinoncel W/m2 is equal to J/s/m2. Now, it takes 2.450 MJ to evaporate 1 liter of water. You have 86400 s in 1 day. Take the average LE in W/m2. Divide by 2450000 to get L/m2/s and multiply by 86400 s/d so you will get L/m2/day

@@FranciscoVillalobos 1/2450000*86400=0.04 as convertion coefficient. thank you for the detailed explanation.

Por lo pronto, en settings use la resolución más alta. Después, si lo ve pequeño, haga zoom

I'm only providing help regarding the tutorials I have produced

The error is self explanatory. The date format is wrong
