Abstract

The field experiments were conducted at Khalsa College, Amritsar to study the nitrogen management by using LCC in wheat (Triticum aestivum L.) and maize (Zea mays L.) on sandy loam soil, low in organic carbon and available N and high in available P and K during the rabi and kharif seasons of 2014–15. The experiments comprised three nitrogen management treatments including control, recommended N and LCC replicated four times for both the crop seasons. LCC and recommended nitrogen treatments had shown significant effects on yield and yield parameters over control (no nitrogen). LCC produced the maximum wheat grain (43.8 q/ha) and maize grain (54.4 q/ha) yields followed by recommended N (41.3 and 51.3 q/ha) and both were statistically at par. Total income, net profit and B: C ratio were also highest in LCC than other nitrogen management treatments in both the crops. However, higher NUE in wheat and maize was recorded in LCC over other nitrogen management treatments because of less amount of nitrogen used.
