Real time nitrogen management through leaf colour chart and chlorophyll meter in wheat (triticum aestivum l.) of jammu

A field experiment was conducted to assess the effect of real time nitrogen management through leaf colour chart and chlorophyll meter in wheat. The experimental results revealed that Leaf color chart <_5 based nitrogen application recorded significantly higher growth, yield and yield attributes, which was statistically at par with leaf color chart <_ 4, sufficiency index and leaf color chart <_3. However, recommended nitrogen application recorded significantly highest agro physiological efficiency. Sufficiency index recorded highest benefit cost ratio (B:C) which was followed by leaf color chart <_ 4 and leaf color chart <_ 5.
