Sensor guided nitrogen management in maize based cropping system under conventional and conservation agriculture practices

Title of project: Sensor guided nitrogen management in maize based cropping system under conventional and conservation agriculture practices

Objective:

  • To study the effect of precision nitrogen management on growth, yield and economics of maize-based systems.
  • To work out the effect of precision nitrogen management on nutrient productivity, nitrogen saving, water-use efficiency and energy dynamics.
  • To study effect of precision nitrogen management practices on soil properties in maize-based systems.

Project team: S.L. Jat, A.K. Singh, Meena Sekhar, Suby SB, C.M. Parihar
Major achievements:

  • Green seeker (GS) based N application had a wide range (120 to 190 kg/ha) in various cropping systems and residue management scenarios that showed calibration curve developed by IIMR is working.
  • Under conventional tillage system, GS based N application was 13 to 40 kg lesser than the recommended N (150 kg/ha) in maize.
