Blurb/Shorttext:
A crop nutrient survey was conducted in 54 mandals covering 150 rice fields in Karimnagar district of Andhra Pradesh for developing the DRIS foliar diagnostic norms for N, P, K, S, Zn and Fe and to identify the yield limiting nutrients in rice. The DRIS derived sufficiency ranges for N, P, K and S from nutrient survey of rice crop in the district were 2.2 to 3.6, 0.30 to 0.38, 2.02 to 2.89 and 0.18 to 0.34 per cents respectively. The limits for Zn and Fe were 14.9 to 26.3 and 19.7 to 167.8 mg kg-1 respectively.The number of nutrients diagnosed as yield limiting by DRIS are more than those identified by the CNC method.
