Hours after it was rolled out by Prime Minister Narendra Modi, BSP chief Mayawati trashed the ambitious PM-KISAN scheme -- which aims at giving Rs 6,000 annually to small and marginal farmers -- as "inadequate and humiliating"."Giving @ Rs 17 per day to few farmers just before Lok Sabha elections is pure hoodwinking," the Bahujan Samaj Party leader tweeted."The Rs 500 a month to poor farmers under PM Kisan Samman Nidhi is an insult to the farmers. Farmers believe in their labour and want remunerative price of their produce but BJP mentality to give them little monetary help is atrocious and arrogant. BJP has failed to fulfil their promise," she added.Launching the scheme earlier in the day, Modi said the opposition was rattled with the initiatives being announced by his government for farmers.
