Influence of Crop Geometry and Nitrogen Levels on Growth and Yield of Black Wheat (Triticum aestivum L.)

Abstract

To evaluate the influence of crop geometry and nitrogen levels on growth and yield of black wheat (Triticum aestivum L.) a field experiment was conducted during Rabi season of 2022-23 at research area of cereal and pulses section, at Agricultural Research Farm of United University, Prayagraj-211012, Uttar Pradesh, India. The experiment consisted of three, doses of nitrogen (@75, @100, @125 kg/ha) and three spacing (15 cm x 10 cm, 20 cm x 10 cm, 25 cm x 10 cm). The experiment was arranged in a statistical design of Randomized Block Design (RBD) with three replications. Report of study indicate that, among different nitrogen levels the application of Nitrogen @125 kg/ha + 25 cm x 10 cm spacing produced significantly superior plant height (103.55 cm) and plant dry weight (30.55 g). However, the application of Nitrogen @125 kg/ha + 25 cm x 10 cm spacing was found to be significantly maximum number of effective tillers/plant (19.400), spike length (10.88 cm), test weight (37.60 g) and number of grain/spike (58.93), grain yield (8.55 t/ha), straw yield (9.61 t/ha) and harvest index (46.98%) was produced by the application of Nitrogen @125 kg/ha + 25 cm x 10 cm spacing. Thus the application of the RDF + 25 cm spacing helped in increase in yield over control.
