Other claims from this paper (16)
- Intervention effect Rip tillage (RT) gave the highest maize yield, followed by MT and ST.
- Association Yield did not differ significantly between RT and MT.
- Association RT and MT yields were significantly higher than ST yield.
- Association In the relatively dry year 2015, ST yield was almost on par with MT and RT.
- Association A positive interaction between tillage and fertilization was evident for maize yield.
- Association Yield variation was higher in non-fertilized (N0) tillage plots (CV=40.07) than in plots receiving N80 and N160 kg ha-1 (CV=22.42).
- Intervention effect Fertilizer application greatly increased maize yield and accounted for 43 % of yield variance.
- Intervention effect The highest maize yield (11.88 t ha-1) was obtained with N160 kg ha-1, followed by N80 kg ha-1 (10.83 t ha-1).
- Intervention effect The lowest maize yield (7.48 t ha-1) was recorded in nonfertilized plots (N0 kg ha-1).
- Observation The crop year interaction for maize yield was highly significant.
- Association In 2016, a higher maize yield was obtained with increased fertilizer dosage under favorable growing conditions.
- Association With 2015 as a dry year, higher fertilizer dosage (N160 kg ha-1) gave no yield-increasing effect.
- Association FAO 380 yielded more than FAO 490 (11.09 vs 10.60 t ha-1).
- Association A positive correlation exists between fertilizer dosage and water supply.
- Observation A lower fertilizer dosage gave optimum results in the drier year with limited water supply.
- Recommendation Ripper tillage and strip tillage can be suitable alternatives to conventional mouldboard tillage, especially in drier conditions.
