The effect of drip irrigation on potato yield and quality

Popis výsledku v původním jazyce

In recent years growing season, not only in the Czech Republic, is characterized by increased temperatures and drought, and/or non-uniform rainfalls, often of local character. These climate changes negatively affect especially potatoes. This weather course was expressed as 40 % potato yield reduction in past years. Possible and to date known solutions consist in an application of individual elements of growing technology, most often irrigation (Badr et al., 2010, based on Ahmad et al., 2010, Hamouz et al., 2007). Between 2016 and 2017 Potato Research Institute in Havlíčkův Brod realized a project directed to evaluation of new technological procedures for effective water management under drought conditions. Growing technology using drip irrigation combined with fertigation was verified. After the planting irrigation pipes were put under the soil surface on the ridge top. For this purpose construction designs were elaborated and technical devices were realized for verification and development of a functional sample of device for incorporation and extraction of irrigation pipes for mechanical establishment of drip irrigation on fields with conventional bed soil preparation after de-stoning at potato planting. In two different localities (early production and potato production region) exact field trials were established. Two varieties differing in growing season duration were used for planting – early variety Monika and medium-early Jolana. Eight variants of irrigation combined with N fertilization were established in four replications for each variety in both localities. A technique for irrigation management was determined based on soil conditions. Soil moisture was separately measured with VIRRIB sensor in each irrigation variant. Concrete moisture, when irrigation was automatically switched on, was calculated from the values of usable water capacity and wilting point based on determination of soil-moisture constants in given locality. N fertilization during season was done in two variants: 120 kg N/ha prior to planting and 60 kg N/ha at planting + 60 kg N/ha in four irrigation rates (15 kg N/ha for each), using Dosatron D3 device, which adds fertilizer solution to irrigation water based on set concentration. In non-irrigated variant with fertilization during season N rate was supplied in the same fertilizer as single spreading on the soil surface. In the trials an effect of irrigation on all studied factors was detected. Potato yield was statistically significantly increased in variants with irrigation compared to non-irrigated variants. Simultaneously, semi-pilot trials were established in an agricultural enterprise. A half of trial area was irrigated and a half was without irrigation. Two varieties, Antonia (medium-early) and Soraya (early) were involved in the trials. The irrigation resulted in 20.1 % yield increase. Irrigation also had an effect on tuber size distribution. We can conclude that yielding performance of tubers sized more than 35 mm in both varieties was increased due to irrigation. An increase of 7.6 t/ha and 8.3 t/ha, i.e. approx. 20 %, was recorded for Antonia and Soraya, respectively.
