“…Along with fertilization [12], irrigation of radicchio is paramount to achieve satisfactory productivity [13,14]. Irrigation is carried out in several ways depending on water availability and technological advancement of the farm, going from furrow irrigation [10] to sprinkler techniques [15] or drip irrigation [16].…”

Red chicory (radicchio) plants produce leafy heads that are of great commercial interest and they require a proper irrigation technique to achieve satisfactory productivity. The use of mini-sprinklers with high-frequency irrigation schedules may increase radicchio productivity, provide better growing conditions due to timely intervention, and save water, but so far little research has been carried out on this topic. This experiment aims at evaluating the effect of two mini-sprinkler irrigation schedules (high- and low-frequency) on radicchio yield and growing conditions over a 5-year cultivation period. Marketable radicchio head production was on average 12% greater with the high-frequency schedule (26.5 t ha−1) than with the low-frequency schedule (23.6 t ha−1), mainly due to greater head weight. The number of underweight, pre-flowering, rotten, and missing plants was significantly different between the two schedules when these variables were considered separately, but the overall number of marketable plants was greater in the high-frequency schedule during certain years. In general, the high-frequency schedule permitted to increase both radicchio yield and to reduce irrigation water use on average by 14% (−24 mm in volume), improving the irrigation water productivity by 19% (from 0.18 t mm−1 of the low-frequency schedule to 0.22 t mm−1 of the high-frequency schedule). Reducing the irrigation interval permits a timely adaptation to the weather course and improves radicchio growing conditions, presenting itself as a valid strategy that could be adopted by the farmers, upon appropriate consideration of energy and management costs.

“…Although it has been considered a traditional Italian fresh leafy green, radicchio is now commonly being grown throughout Europe, Japan, the United States, Guatemala, Mexico and South America [8]. Sprinkler irrigation practices have been shown to have a significant impact on both quantity (rate of growth and biomass produced) and quality of field-grown radicchio [2,4,16,17]. The most commonly used irrigation systems in Italy for radicchio production are large irrigation guns with 28 -32 mm diameter nozzles supplied by pumps coupled to the power take-off (PTO) of a tractor and operating at 4 to 8 bar of pressure at the nozzle.…”

Gun sprinklers were commonly used in Italy to irrigate Radicchio. Although this high-pressure irrigation system allows large areas to be irrigated in a short time, it has some major disadvantages. Disadvantages include the impact of the drops on the soil and crop can be very strong, the high volume of water used tends to increase water use and runoff and water distribution uniformity is low. A 3-year experiment was conducted in North-East Italy in order to evaluate the possibility of using a mini-sprinkler irrigation system with low-volume application rates. The use of mini-sprinkler resulted in a higher distribution uniformity, higher Christiansen uniformity coefficient and a higher water use efficiency. Energy cost was also lower when the mini-sprinkler system was used for irrigation as compared to the irrigation gun system. Radicchio head weight and marketable yield were higher when plants were irrigated with the mini-sprinkler as compared to those irrigated with the irrigation gun. Therefore, the use of mini-sprinklers resulted in not only a reduction in water use and energy cost but also an increase in radicchio production. 346Lucia Bortolini et al.

“…In dry years, flat cultivation provided better water infiltration than cultivation on ridges, which contributed to the growth of leaves. This view is also shared by Adamicki et al [37] and Babik et al [38]. During the cultivation of radish ' Agata' , the combination of flat cultivation with soil mulching appeared to be optimal for the growth, while the shortest leaf rosettes were produced by radish grown on ridges without any mulch [39].…”

Effect of cover crops on emergence and growth of carrot (Daucus carota L.) in no-plow and traditional tillage

The aim of the experiment was to determine the influence of cover crop biomass incorporated into the soil at different times and using different treatments on carrot emergence and growth. 7 species of cover crops were included in the study: Secale cereale, Avena sativa, Vicia sativa, Sinapis alba, Phacelia tanacetifolia, Fagopyrum esculentum, and Helianthus annuus.Number of emerged carrot plants significantly depended on the cover crop used and on the method of pre-winter and spring pre-sowing tillage. Carrot emerged best after a rye or oats cover crop. Regardless of the cover crop species used, the largest number of carrots emerged in cultivation on ridges. In other variants of no-plow tillage, number of seedlings was significantly lower and did not differ from that under traditional plow tillage. The highest leaf rosettes were formed by carrot growing after a rye or oats cover crop. The highest rosettes were produced by carrots in the treatments where tillage was limited to the use of a tillage implement in spring and the lowest ones after pre-winter plowing. The effect of tillage on the emergence and height of carrot leaves largely depended on weather conditions in the successive years of the study. The largest number of leaves was found in carrots grown after a buckwheat cover crop and in cultivation without cover crop, while the smallest one after phacelia and white mustard. Carrots produced the largest number of leaves after a sunflower cover crop and the use of a tillage implement in spring, while the number of leaves was lowest when the mustard biomass was incorporated into the soil in spring. The use of cover crops significantly increased the mass of leaves produced by carrot as compared to the cultivation without cover crop. The largest mass of leaves was produced by carrots grown after the phacelia and mustard cover crops. Conventional plow tillage and pre-winter tillage using a stubble cultivator promoted an increase in the mass of carrot leaves.
