Abstract: A study was undertaken in northern dry zone and northern transition zone of Karnataka with the objectives of characterization of sugarcane growing Vertisols, identification of micronutrients constraints by GIS technique and to study the response of sugarcane to identified micronutrients constraints. Characterization of six Vertisol pedons from both the zones revealed that the soils were deep to very deep with abundance of CaCO3 concretions (89.7 to 146.5 g kg-1), slightly saline to alkaline nature. Organic carbon status in the pedons was low (1.19 to 6.2 g kg-1). Distribution of Zn, Fe, Mn, Cu and B in the profiles was irregularly distributed with increasing soil depth. Soil fertility maps of the selected micro-watersheds prepared by GIS technique (Arc GIS 10.0 software) revealed that, soils were alkaline in nature (7.44 to 9.33) with CaCO3 accumulation (37.30 to 22.85 g kg-1) and low in organic carbon status (2.2 to 17.8 g kg-1). The major portion of the area in the micro-watersheds studied were deficient in available N, P and S with higher level of available potassium, copper and manganese in the soils. Area under deficiency of Zn (58.30 and 63.50%), Fe (69.90 and 64.6%) and B (64.30 and 61.80%) in the micro-watersheds of both zones, respectively. Field experiments were conducted in each zone for both plant and ratoon crops to study the response of sugarcane zinc, iron and boron. The results of the experiments revealed that, in comparison to control, application of vermicompost chelated iron sulphate and zinc sulphate each @ 50 kg ha-1 plus borax @ 5 kg ha-1 along with three foliar application of FeSO4 and ZnSO4 each @ 0.5 per cent and boron @ 0.1 per cent increased all the growth parameters, cane yield (46.31%), quality parameters (brix, pole, juice purity, juice reducing sugar and CCS per cent) and uptake of Zn, Fe and B by sugarcane in plant and ratoon crops under both northern dry zone and northern transition zone of Karnataka with the lowest values recorded in the treatment receiving only RDF.
