Abstract This chapter discusses the importance and implications of nitrogen, phosphorus and potassium as essential nutrients and the application of molecular breeding and functional genomics for improving nutrient-use efficiency in wheat are presented. Improvement of nutrient-use efficiency through genetic modification and impact of climate change on nitrogen, phosphorus and potassium management were also discussed.

We investigated how N availability affected the wateruse efficiency (WUE) of a perennial ryegrass/white clover sward under different soil moisture regimes at Lincoln. Four combinations of ± N fertiliser and ± irrigation (I) were applied to plots rotationally grazed by sheep, and WUE (yield/water used) was measured from August 2011 to May 2013. The +N swards had a higher annual WUE than -N swards (27 vs 19 kg DM/ ha/mm) due to greater yields for the same amount of water used. This was associated with higher N contents in the +N grass herbage. The N response of WUE was consistent across soil moisture regimes and for most of each year. Irrigation did not affect annual WUE because the +I swards yielded more herbage but used more water than the -I swards. The results suggest that high WUE can be achieved by strategic applications of N fertiliser, use of pure legume swards, and through management that encourages clover growth in grass/clover swards.

Different Levels

A field experiment was conducted at Post Graduate Institute Instructional Farm of Mahatma Phule Krishi Vidyapeeth, Rahuri, during rabi 2017-2018 to study the effect of different levels of phosphorus and zeolite on yield and its use efficiency and availability of nutrients. There were eight treatments replicated thrice in RBD. The significantly highest bulb with 150% of the recommended dose of P2O5 175 kg along with 120 kg ha-1 of zeolite application followed by the zeolite @ 120 kg ha¬¬¬¬¬¬-1 + 125% P2O5of RDF. However, the highest phosphorus use efficiency was observed in the treatment with 75% P2O5 of RDF and recommended dose of nitrogen and potassium fertilizers along with 120 kg ha-1zeolite and 20 t ha-1 farm yard manure. The available nitrogen, phosphorus and potassium were significantly higher in treatment with zeolite @ 120 kg ha-1 + 150% P2O5 of RDF. Thus recommended dose of phosphatic fertilizer can be reduced by 25% when used along with 120 kg ha-1zeolite and recommended dose of nitrogen and potassium fertilizers for obtaining optimum yield of onion.

Knowledge about nutrients use efficiency in production of tubers in different potato varieties provides important basis to optimize the use of fertilizers in the crop. Thus, this study aimed to determine the productivity and the coefficient of biological utilization (kg of dry matter produced per kg of accumulated nutrient) of nitrogen (N), phosphorus (P) and potassium (K) of thirteen potato cultivars, and compare the extraction and the exportation of N, P and K of Ágata, Asterix and Atlantic cultivars that present low, medium and high content of dry matter, respectively. The treatments consisted of thirteen potato cultivars: Ágata, Atlantic, FL2215, FL2027, FL1867, FL2221, Asterix, BRSIPR Bel, Cupido, Nicolet, Accumulator, Verdi and Taurus. FL2027 cultivar was more productive. The cultivars differs as the coefficient of biological utilization of N, P and K. The Atlantic cultivar extracted and exported more N, P and K than Ágata and Asterix.
