Impact of Nano Urea and Zinc Foliar Applications on Growth and Yield Parameters of Radish (Raphanus sativus L.) cv. Pusa Chetki Across Two Seasons

A field experiment was conducted in the Orchard, Department of Horticulture, Faculty of Agriculture, Annamalai University, Annamalainagar during February to April 2024 and in a farmer’s field, Anthiyur, Erode during June to August 2024 in two seasons. It was laid out in randomized block design with eleven treatments replicated thrice. The treatments comprised with combinations of nano urea and zinc foliar applications along with a control. The results of the experiment revealed that the maximum values for pre- harvest observations viz., shoot length, number of leaves, leaf area; post- harvest observations like weight of shoot, weight of root, root: shoot ratio, length of root, grith of root, root yield plot-1, root yield hectare-1 and biochemical attributes like ascorbic acid and calcium content were recorded in the plots which received the application of basal RDF plus foliar spray of 0.4 per cent nano urea plus 0.1 per cent nano Zn. It was engrossing to observe that the nutrient uptake of nitrogen, phosphorus, potassium, zinc and benefit cost ratio were also influenced the maximum by the same treatment. This was followed by the treatment which received the application of basal RDF plus foliar spray of 0.4 per cent nano urea plus 0.05 per cent nano Zn and the least values for all attributes was noted in control.
