While looking for the right variety for no-till farming, a friend called Gireesh from Pallassana, Palakka suggested Aruvakkari rice. This is a traditional variety and comes under Palakkadan Matta category. Medium duration around 120 days, and grows tall - close to 5 feet or so.
As per the NBPGR database, there is a variety called 'Aruvakkali' , is it same as Aruvakkari? Not sure, please see the link
Also there is a variety called 'Erumakkari' in Kerala Agriculture University paper
Whether both these are same, again not sure. The variety 'Erumakkari' was referred by an old farmer lady when I met her some time back, according to her it used to give good yield.
Anyway, I will be trying this one in 2018 monsoon season.
