A field experiment was conducted during the period of Rabi 2022 at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (U.P) on the topic “Effect of phosphorus and iron on growth and yield of lentil (Lens culinaris L.)”, to study treatments consisting of three levels of Phosphorus viz. 20 kg, 30 kg and 50 kg/ha and three levels of Iron viz. 5, 10 and 20 kg/ha. The soil of experimental plot was sandy loam in texture, nearly neutral in soil reaction (pH 7.1), low in organic carbon (0.28%), available N (225 kg/ha), available P (19.50 kg/ha) and available K (92 kg/ha). There were 10 treatments each being replicated thrice and laid out in Randomized Block Design. The results revealed that treatment 9 (Phosphorus at 50 kg/ha + FeSO4 at 20 kg/ha) recorded significantly higher plant height (26.03 cm), plant dry weight (11.61 g), number of pods/plant (113.07), number of seeds/pod (1.93), seed yield (1.25 kg/ha) and Stover yield (2.07 kg/ha compared to other treatments.
