Description Forty one field verification trials were conducted with maize (Zea mays L.), rice (Oryza sativa L.) and wheat (Triticum aestivum L. emend. Fiori & Paol.) during 1995-2001 at farmers' fields to ascertain the validity of soil-test based fertilizer prescriptions for achieving specific yield targets in wet temperate zone of Himachal Pradesh. Different fertilizer recommendation methods along with fertilizer doses calculated through fertilizer adjustment equations for varying levels of targeted yields of maize, rice and wheat were evaluated. The fertilizer recommendations based on targeted yield concept were found more precise and dependable up to the yield targets of 5 tonnes/ha for rice and maize and 4 tonnes/ha for wheat, respectively.
