Development of Diagnostic Leaf Nutrient Norms and Identification of Yield Limiting Nutrients Using DRIS in Rose Grown under Protected Conditions

Leaf samples collected from protected cultivation units of rose around Bangalore (Karnataka) and Hosur (Tamil Nadu), when flower buds were at pea size, were processed and analyzed for various nutrients and thus, the data bank was established. By using Diagnosis and Recommendation Integrated System (...
