Impact of Vertisol Technology in India uri icon


  • Research on vertisol technology as a package of options began at ICRISAT in 1974. The technology was first tested and demonstrated on farmers' fields in Andhra Pradesh. Later, on-farm trials were conducted in five states ? Andhra Pradesh, Karnataka, Gujarat, Maharashtra, and Madhya Pradesh ? to understand the dynamics of adoption of various components of the technology, such as summer cultivation, dry seeding, crop protection, improved varieties, proper placement of seed and fertilizer, etc. The survey was conducted in 27 villages, where 500 farmers from low-, medium-, and high-rainfall regions were interviewed using awell-designed questionnaire. This study assesses the extent of adoption of the various components of vertisol technology, identifies the constraints to their adoption,examines farmers' perceptions of the sustainability benefits from it, estimates the on-farm benefits, and details the relative significance of the various components
