| The objective of the present study was to evaluate the effects of crop residue covers (0.0; 4.5; 9.0; 13.5 t ha-1 millet dry matter) on water use and production of onion cultivated in no-tillage planting system (NT) as compared to conventional tillage system (CT). The study was carried out at Embrapa Hortaliças, Brazil, under the typical Savanna biome. Irrigations were performed using a sprinkle irrigation system when soil-water tension reached between 25 and 30 kPa. The experimental design was randomized blocks with three replications. Total net water depth applied to NT treatment was 19% smaller than the CT treatment, however, water savings increased to 30% for the first 30 days following seedlings transplant. Crop biomass, bulb size and yield, and rate... |
