Abstract

The present investigation was emphasized to evaluate the precision nitrogen management using SPAD meter in improving N uptake as well as soil fertility status in rice crop under direct seeded condition.The experiment was conducted at Agriculture Research Farm, Bihar Agricultural University, Sabour, Bhagalpur, Bihar, India during the monsoon season, 2018 including twelve treatment combinations of three rice cultivars (Sabour Ardhjal, Shushk Samrat, Shabhagi Dhan) and four N management levels (Control, Fixed time nitrogen management (FTNM), Real time nitrogen management (RTNM), Adjustable dose of nitrogen management (ADNM)). Results revealed that Shushk Samrat among the cultivars and FTNM among N management practices have recorded highest leaf N content as well as N uptake. There is no major difference observed in soil properties and it might take few years to observe the impact of nitrogen management strategies on soil properties.
