G Kishan Reddy said as informed by the National Crime Records Bureau, many states and UTs have reported "nil" data on suicides by farmers.
The number of suicides involving farmers and farmhands in Andhra Pradesh increased to 1,029 last year from 664 in 2018.
He said the manch opposed the English medium of teaching introduced by the State government.
Activists said women’s lack of visibility as farmers due to lack of land ownership is not reflected in the farmer suicide numbers published by the states.
The number of farmer and agriculture labourer suicides in Andhra Pradesh has come down during 2018, which is good news for the State, a predominantly agrarian-based economy.
According to the data compiled by NCRB, 10,349 people working in the farm sector committed suicide in 2018.
The year 2018 saw more number of suicides by farmers in Telangana, than in 2017 (851) and 2016 (645).
The minister said advisories have been issued to all states and union territories to furnish complete data sets promptly for the speedy publication of ADSI report.
In March alone, 66 farmers have committed suicide in the Marathwada region, which is the most parched and backward region of the state.
Sinha has been agitating for farmers' rights and was recently detained in Akola, Maharashtra while leading a protest for the acceptance of demands of the farmers in Vidarbha.
