The effect of nitrogen and spacing on summer groundnut traits like growth and yield was studied through an experiment performed in 2021 KVK Farm of SHUATS,Prayagraj (U.P) The experiment had 9 different treatments, replicated thrice in a Randomized control design. The treatments encompassed three different levels of nitrogen soil application and three different plant spacings. The outcome of the study revealed that in treatment (T3) the grouping of 30 kg/ha nitrogen + 20 cm × 10 cm spacing resulted in maximum plant height (52.27cm) and in treatment (T6) the usage of 30 kg/ha nitrogen + 25 cm × 10 cm layout resulted in a significant root nodules per plant (39.57) and dry weight (38.00 g). Treatment (T2) showed a maximum crop growth rate (31.44 g/m2/day) in the combination of 25 kg/ha nitrogen + 20 cm × 10 cm arrangement and 20-40 DAS interval. Furthermore, treatment (T6) had a maximum pods per plant (30.80), seed capitulate (2355.6 kg/ha), and haulm yield (3402.3 kg/ha) with 30 kg/ha nitrogen + 25 cm × 10 cm while treatment (T1) obtained maximum harvest index (42.32%) with the use of 20 kg/ha nitrogen + 20 cm × 10 cm.
