Fertilizer N management using optical sensor (GreenSeeker® ) was evaluated at CCSHAU, Hisar. The experiment was laid out in randomized block design with three replications. There were 12 treatments comprising N application with and without using GreenSeeker. N application without using GreenSeeker consisted of two treatments having recommended dose (150 kg/ha) in two (75 kg/ha each) and three (50 kg/ha each) equal splits. | Precision nitrogen management based on NDVI and in-season estimates of response index in wheat
