Enhancing morpho-physiological and yield potential of coriander (Coriandrum sativum L.) variety-Jawahar Dhaniya 1 using foliar application of fertilizers and nano-fertilizers

A study was formulated in the midst of the Rabi season, 2021-2022 at the Vegetable Research Centre, Department of Horticulture, College of Agriculture, JNKVV, Jabalpur (M.P.) to observe the enhancement of morpho-physiological and yield potential of Coriander (Coriandrum sativum L.) var.- Jawahar Dhaniya-1 as an approach towards exogenous application of fertilizers and nano-fertilizers. The experiment was laid out in the Randomized Block Design comprising thirteen treatments and three replications with foliar spray of varied fertilizers and nano-fertilizers at different doses. The investigation substantiated that the var. JD-1 of coriander when sprayed with Nano Urea provided maximum dry matter percentage, chlorophyll content index, leaf area index (LAI), crop growth rate (CGR), and net assimilation rate (NAR). Treatment 4 (T₄: Foliar Spray of 0.25% Nano Urea) produced the highest dry matter percentage of 67.96%, maximum chlorophyll content index of 58.59, and higher leaf area index (LAI) of 7.85 at 80 DAS. Alongside, a higher crop growth rate (CGR) of 8.20 g/cm²/day and net assimilation rate (NAR) of 7.61 g/g/day at 60 DAS - 80 DAS were recorded in the treatment T₄. Thus it can be concluded that the coriander crop when sprayed with nano-fertilizers gave better physiological growth in comparison to when sprayed with traditional fertilizers.
