Abstract:

Diagnosis and recommendation integrated system (DRIS) norms were computed from the data on leaf mineral composition, soil available nutrients, and corresponding mean fruit yield of three years (2016–2019), collected from the set of 50 irrigated commercial ‘Dashehari’ mango orchards, representing 2 locations and 3 basalt derived soil orders (Entisols, Inceptisols, and Vertisols) rich in smectite minerals. The DRIS norms derived primarily index leaves sampled during month of March-April (6–8 months old) suggested optimum leaf macronutrient concentration (%) as: 1.10–2.25 nitrogen (N), 0.09–0.25 phosphorus (P), 0.19–0.45 potassium (K), 1.80–2.45 calcium (Ca), and 0.42–1.01 magnesium (Mg). While, optimum level of micronutrients (ppm) was determined as: 10.60–28.50 zinc (Zn), 101.20–310.50 iron (Fe), 10.50–24.70 copper (Cu), and 69.90–193.90 manganese (Mn) in relation to fruit yield of 30.50–84.69 kg tree−1. The data were divided into high-yielding (>50 kg/tree) and low-yielding (<50 kg/tree) subpopulations and norms were computed using standard DRIS procedures and a preliminary DRIS norms for mango growing in the Akhnoor and Samba district are selected. These norms were developed with data from only one region, so data from future surveys and field trials may subsequently be used to enlarge the database allowing the refinement of model parameters.  The results elucidate that the DRIS model for mango, developed in this study, is a diagnostic tool that may be used to predict if insufficiencies or imbalances in N, P, K Ca, Mg, Zn, Fe, Cu and Mn supplies are occurring in mango production.
