Effect of Tillage and Nitrogen Fertilization on Soil Properties and Yield of Five Durum Wheat Germoplasms in a Dry Area of Morocco

In Morocco, cereal production is below the expected potential. The adoption of best agricultural practices that reduce vulnerability to climate a major requirement. No-tillage (NT) agriculture system could improve by enhancing soil fertility. Some factors, in combination with no-tillage, can further yields, especially choice variety adequate fertilization. objective our study investigate effect no-tillage and nitrogen fertilization on fertility yield five durum wheat varieties developed Morocco long-term (18 years) NT trial at INRA Merchouch experimental station, Morocco. results show tillage type had significant organic carbon CEC (measured before start experiment), as well ammonium nitrates end whereas dose total experiment). Regarding yield, measured experiment during 2020–2021 cropping season, that, under NT, Nachit, Faraj, Louiza grain yields 4.5, 4.3, 3.4 t ha−1 straw 9.8, 7.8, 6.8 ha−1, respectively, I.C M.G germoplasms 4.05 3.72 8.25 8.39 respectively. These values are low for favorable area correspond semi-arid area. addition, no effects were observed due water stress, which reduced use efficiency. Nachit most adapted highest (5.1 ha−1) (20 kg N ha−1), followed Faraj (4.7 still but higher (40 (4.5 minimum both CT. conclusion, performed conditions minimal dose. However, reduced, owing
