TL;DR
Using the GreenSeeker sensor to apply nitrogen more precisely in mustard crops improved productivity, profitability, and nitrogen use efficiency while reducing environmental risks.
Contribution
This study is the first to evaluate GreenSeeker sensor-based nitrogen management in mustard for productivity, profitability, and environmental benefits.
Findings
GreenSeeker-based nitrogen application increased seed yield, net returns, and benefit-cost ratio significantly compared to traditional methods.
Split nitrogen application using GreenSeeker boosted oil yield and oil content while improving soil organic carbon.
The sensor reduced nitrogen requirements by 15–20% while enhancing yield by 18.7% over recommended doses.
Abstract
Unremitting decline in crop productivity and nutrient recovery are resulted due to dearth of need based fertilizer recommendation over blanket application apart from nitrogen pollution in several means. An advance nutrient management tactic, GreenSeeker (GS) has developed and used in many field crops following the principle of four “R” (right source, right amount at right time, and place) nutrients stewardship technologies. But no studies have been conducted for evaluation of GS in mustard for improving productivity, profitability and nutrient use efficiency (NUE) while minimizing environmental risks. With this objective, a study was planned to conduct an experiment in rabi season of 2021–22 and 2022–23 to assess optical sensor based nitrogen management in mustard over blanket recommendation. The experiment was comprised of ten N treatments including control in randomized block design…
