Accentuating the Role of Nitrogen to Phosphorus Ratio on the Growth and Yield of Wheat Crop

Nitrogen (N) and Phosphorus (P) deficiency is a major yield limiting factor across the globe their proper management plays vital role in optimizing crop yield. This field experiment was conducted to assess impact of soil plant nitrogen N P ratio on growth wheat (Triticum aestivum L.) alkaline calcareous soil. The study consisted various levels (0, 40, 80, 160 kg ha−1 as urea) phosphorus 30, 60, 90 P2O5 diammonium phosphate), carried out randomized complete block design (RCBD) with factorial arrangement having three replications. result showed that addition significantly improved biological (10,052 ha−1), grain weight (3120 chlorophyll content at tillering stage analysis development (SPAD) value (35.38), uptake straw (33.42 K (192 ha−1) compared other levels. In case P, had resulted maximum (9852 (3663 (SPAD 34.36), (6.68 mg kg−1) (171 straw. sole use have positively influenced but interaction didn’t response present reveals SPAD (chlorophyll meter) better choice for determining concentrations estimate potential.
