Siddaramaiah's Cabinet on 18 May 2013, at the very young age of 40. During this time he came up with various initiatives to promote the native grain 'Millet' and bring it back into people's diets. Krishna Byre Gowda believed that in a water-deficient state like Karnataka, this crop has a potential to go a long way as it just uses 25% of water to grow in comparison with rice. During his tenure, 20 Millet Melas at various locations across Karnataka were organized and the '1st Organic and Millet International Trade Fair' was organized which attracted over 2 lakh visitors and generated businesses worth 110 crores.

He also introduced Krushi Bhagya to provide farmers with farm ponds locally known as
"Krishi Hondas" not only to protect crops during severe droughts but also to ensure a good yield. This had resulted in over 20% higher yield in the crops and also protected the crops in the times of famine and drought. He also served as the minister for rural development, law and parliament affairs in the cabinet of
H. D. Kumaraswamy between 2018 and 2019.
