Abstract:
A field experiment entitled “Effect of fertilizer application on water and nutrient use efficiency of wheat under limited irrigation” was conducted during Rabi 2019-20 at Soil Research Farm, CCS Haryana Agricultural University and Hisar. The study includes three irrigation levels in the main plot viz., one (CRI), two (CRI and flowering stage) and three irrigations (CRI, late jointing and dough stage) and four fertilizer levels in the subplots (control, 75, 100, 125 per cent RDF). The results indicate that the three irrigations and 125 per cent RDF under fertilizer treatment resulted in higher N, P and K content and uptake both in grain and straw, agronomic efficiency, apparent recovery. The water use efficiency was highest under two irrigations followed by three and one irrigation, but in case of fertilizer levels, it was found to be highest under 125 percent RDF followed by lower fertilizer levels.
