Within the framework of the XXIV National Potato Days, on 10 April, the planting of potato from the variety of Colomba (produced by the Dutch grower HZPC) was started in the 30 hectare trial field located in the HR Kalinowa farm. Four-row planter manufactured by GRIMME type GL 34T along with New Holland T 6030 tractor were used for this planting. Potatoes were planted at a spacing of 90 cm and density of 26 cm. Depth of planting: 17-18 cm from the top of the formed coulter. Prior to planting, the mineral fertilization, on the basis of a soil chemical analysis carried out by the Dutch laboratory Eurofins Agro Wageningen, was made. The field was planted with the rotary harrow LEMKEN type Orion 101 aggregated with the New Holland 8870A tractor. The experience will be performed in this field. We will present the program of protection and foliar fertilization from six phytopharmaceutical companies and fix fertilization companies.
