In his condolence message to Tikait's elder son Narendra Pal Tikait, Singh said: "Chaudhury Tikait's commitment to the welfare of farmers and to rural India was deep and unwavering."
"His work was a powerful influence across the country and inspired the formation of many other organisations devoted to the cause of farmers," he said.
Describing Tikait as a "fiercely independent" person, Prime Minister said "he resisted the pull of politics all his life. His work, his courage of conviction and his simplicity made him a unique leader."
In Lucknow, Chief Minister said: "Tikait worked through out the life in the interest of farmers and fought for their cause. His works will always be remembered." Meanwhile, JD(U) leader Sharad Yadav said the death of Tikait is a loss which cannot be compensated.
"Tikait was a symbol of relentless struggle against farmers exploitation. True homage to him will be stopping the ongoing loot of farmers land in Uttar Pradesh," Yadav said in his condolence message.
Former BJP president Rajnath Singh said Tikait dedicated his life for the welfare of farmers.
"He was free from all stigma of corruption and he lived a simple life. We have lost a true friend of farmers," he said.
