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.
