Abstract:
Crop spacing is very important management practices for efficient crop production and nitrogen takes part in many physiological and biochemical plant processes and is a structural unit of amino acids, nucleic acids, enzymes and proteins, chlorophyll, and cell wall. Efficient crop management through spacing and with fertilization is necessary in both economic and environmental terms. This minimizes nutrient losses to the environment while producing optimum crop yields. A field experiment was conducted during Rabi season of 2019-20 and 2020-21 at experimental field of Crop Research Farm, Department of Agronomy, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology and Sciences (SHUATS), Prayagraj (U.P.) to determine the “Influence of Crop Geometry and Nitrogen Levels on Growth Indices of Quinoa (Chenopodium quinoa Willd.)”. The experiment consisted of four crop geometry (15 cm × 10 cm, 25 cm × 10 cm, 35 cm × 10 cm, 45 cm × 10 cm,) and five doses of nitrogen (control, 25, 50, 75 and 100 kg/ha). The experiment was arranged in a statistical design of Split Plot Design (SPD) with three replications. Report of study indicate that, among different nitrogen levels the application of 100 kg N/ha at 45cm × 10 cm spacing produced significantly superior plant dry weight (30.77 and 33.61 g) and AGR (1.18 and 0.17 g/day). The highest AGR produced by the 60-80 DAS application of 100 kg N/ha at 35 cm × 10 cm spacing. However, the highest CGR produced by the 60-80 DAS application of 100 kg N/ha at 15 cm × 10 cm was found to be significantly. However, the highest RGR absorbed at 25 kg N/ha at 35 cm × 10 cm was found to be non-significant.
