- Abstract
A field experiment was conducted in the farmer's field at Vijaypura, Bengaluru Rural District during kharif 2017, to study the effect of soil and foliar application of zinc on nutritional composition and uptake by knol khol. The experiment was laid out in a randomized complete block design with 10 treatments replicated thrice. The experimental results indicated that significantly higher nitrogen (2.36%), phosphorus (0.37%), potassium (1.60%), sulphur (0.65%) and zinc content (36.48 mg kg-1) was recorded in knol khol shoot by application of RDF and FYM along with 4 kg of zinc through ZnSO4 as soil application and 0.14 per cent zinc through zinc sulphate as foliar spray (T9). Significantly higher nitrogen (2.48%), phosphorus (0.39%), potassium (2.24%), sulphur (0.82%) and zinc content (38.67 mg kg-1) was recorded in knol khol knob with the combined soil and foliar application of zinc @ 4 kg and 0.14 per cent through zinc sulphate respectively, along with RDF and FYM (T9). Uptake of nitrogen (100.05 kg ha-1), phosphorous (15.70 kg ha-1), potassium (72.74 kg ha-1), sulphur (28.76 kg ha-1) and zinc (154.96 g ha-1) by knol khol crop was recorded significantly higher in T9 (4 kg of zinc through zinc sulphate as soil application + 0.14 per cent zinc through zinc sulphate as foliar spray along with RDF and FYM).
