Dear all,
i am working on SWAT to simulate evapotranspiration, in order to set-up the the model i need some crop dataset for State of Tamil Nadu. Datasets are as follows
1.) Crop Operation Data (Dates of Planting, Fertilisation, Irrigation Scheduling, harvest/Kill etc.)
2.) Crop parameter (LAI, BIOMASS and Number of heat units required to reach plant at maturity
Can you anybody suggest where i can get these data?
Thanking you all.

Check this web page may be usefull for you

Thanks Jaime, i have seen this page earlier, it is useful but not sufficient.
You can get these details from Tamil Nadu Agricultural University (TNAU) website http://agritech.tnau.ac.in/. However these may be of general in nature but if you are working for specific crops in a particular study area, you have to contact the concerned village level authorities . Besides, if you are interested I may be able to help you. You can mail me the details in [email protected]
I dont know what kind of information you need but in glasshouse production we do crop registration. Its mean that every week dates about plant (size, leaves fruit) and climate are registred (see sheet crop registration). Values differ for different varieties, greenhouses etc. Regarding irrigation for every Joule radiation we use 2 ml water/m2.During cultivation of course we do deleafing (optimal LAI 3-4,5).
Can you anybody suggest where i can get these data?
Ans.
''Crop Operation Data'' get from any head office of agriculture extension department in the area. They only can provide you accurate information, because they have field officers, who are daily engaged with growers/farmers.
Crop parameters: This data you can obtain from district head office of research station.
Only this way you can get an accurate and efficient data. From net website, you can not get accurate information.
Kind regards, SJ
