Wheat Yield Versus Seed Bed Conditions

The objectives of the research were to study the effect of three soil moisture contents at plowing ((sic)(1), (sic)(2); (sic)(3) (8.60, 10.35,11.61) (w/w), two plowing speeds: S-1; S-2 (1.79; 9.6 km. hr(-1)) and three plowing depths d(1), d(2); d(3) (10, 20; 30 cm) on wheat yield and quality. The field experiments were conducted in the experimental farm of National Research Centre on sandy soil at El-Nubaria District, El-Behaira Governorate, Egypt. The effect of., d and S on yield and its quality of the wheat crop could be put in the following descending orders: ((sic)(3)>(sic)(2)>(sic)(1)), (S-2>S-1) and (d(3)>d(2)>d(1) cm). The interactions among factors were significant at the 0.05 level. The maximum and the minimum values of yield and its quality were recorded at the interactions: (sic)(3) x S-2 x d(3), and (sic)(1) x S-1 x d(1), respectively. The interaction (sic)(3) x S-2 x d(3) could be recommended for maximum wheat yield and its quality. Finally, the interaction: (sic)(1) x S-2 x d(1) was the most economic.
