Table 1. Description of tillage practice and nitrogen treatments.

Tillage	Nitrogen	Fertilizer	Practice during fallow season	Farming method	Cultivation method
No-Tillage (NT)	0, 90, 150 and 210 kg ha−1	N (urea containing 46% N), was applied in two split doses; P2O5 (150 kg ha−1), and K2O (90 kg ha−1) were applied once before sowing	No-tillage	rotary tillage and land leveling were performed before sowing for planting preparation	Seeds were sown at a density of 225 ×104 ha−1 by drilling method and row spacing was 20 cm
Deep Tillage (DT)	0, 90, 150 and 210 kg ha−1	N (urea containing 46% N) was applied in two split doses; P2O5 (150 kg ha−1), and K2O (90 kg ha−1) were applied once before sowing	Deep tillage was performed with furrow plough at the depth of 25–30 cm	rotary tillage and land leveling were performed before sowing for planting preparation	Seeds were sown at a density of 225 ×104 ha−1 by drilling method and row spacing was 20 cm
