%X An experimental study is presented on the effect of
Conservation Agriculture (CA) compared to Conventional
Agriculture (ConvA) upon Maize Yield based on split-plot model.
Two factors have been considered: A Factor-Fertilization with two
variants: A1- N40P40 kg/ha and A2- N90P70 kg/ha; B Factor- Crop
protection with 4 variants : B1- 4 treatments, B2-3 treatments, B3- 2
treatments and B4- 1 treatment. In comparison with conventional
agriculture, CA determined lower maize yields. Fertilization is the
key factor determining a yield gain of 973.58 kg/ha in ConvA and
1,123.33 kg/ha in CA. A reduced number of treatments determined a
yield decline. The A-B interaction had a positive effect on maize
yield when a larger amount of fertilizer and 4 or 3 treatments were
applied in ConvA and a benefic in CA for highest fertilization level
and 2 treatments. The B2A2 ConvA variant was the most efficient
leading to 302.67 kg/ha gain while B3A2 CA variant brought 181.33
kg production gain.
