Abstract
The field experiment was conducted at Students Farm, Sindh Agriculture University, Tandojam, Pakistan to observe the emergence of maize and nitrogen use efficiency of the crop under different fertility regimes (0-0, 90-00, 90-60, 90-90, 90-120, 150-00, 150-60, 150-90 and 150-120 N-P kg ha-1) applied in the plots ploughed through tillage practices with cultivator, chisel and desi plows. Better emergence was obtained with 90-90 NP kg ha-1. The seedling emergence decreased at higher rates of N and P. The interaction of tillage × fertilizer revealed that fertilizer at the rate of 90-150 kg ha-1 and tillage practices with cultivator exhibited higher seedling emergence, while the plots ploughed with chisel plough and desi plough recorded decreased emergence. However, chisel ploughing recorded higher fertilizer nitrogen use efficiency than the plots ploughed by cultivator or desi plough. Nitrogen use efficiency at high levels of nitrogen applications was low than in the low rates of N incorporation. It was concluded that tillage practices should be performed with cultivator and 90 kg N ha-1 is suitable for good seedling emergence and crop yield of maize
