Fertigation of Primocane-Fruiting Raspberry – Leaf and Soil Nutrient Content Between Applications

Abstract

Amongst the agrochemicals, fertilizers have been the most frequently applied through microirrigation systems (fertigation). Although the method has been developed to a high technical level, there is yet a lack of information concerning the optimum timing and the doses under multiple fertilizer applications. The subject of the present article is the fertilizers' fate in the root zone and the raspberry plants' nutritional status between the fertigation events, under three levels of drip water supply-100%, 75%, and 50% of the estimated crop evapotranspiration. The study was based on laboratory analyses of soil, soil solution and plant samples. It was found that fertigation maintained constant and sufficient concentrations of N, P, and K in the soil providing optimum mineral nutrition for the raspberry plants. Proper irrigation and fertigation management could successfully retain the fertilizers in the root zone, thus preventing losses and eventual pollution of soil and groundwater.

Chemical Composition, Antioxidant and Antimicrobial Activity of Raspberry, Blackberry and Raspberry-Blackberry Hybrid Leaf Buds

“…There were small, often statistically insignificant differences in the content of minerals between the buds of the raspberry, blackberry, and raspberry-blackberry genotypes, which can be explained by the fact that the fertilization level, location, and genus were the same in all cases ( Table 1 ). These factors largely determine the quantity of phytochemicals in plant material [ 12 , 13 ]. There were no statistically significant differences between raspberry cultivars in the content of K, Mg, or Cu in the buds.…”

Estimation of the macro- and micronutrient status of raspberries grown in the Lublin region

“…One of the widely used tests of the mineral nutrient status in raspberries is the determination of the level of macro-and microelements in leaves. In addition to genetic traits, the concentration of elements in leaves largely depends on the content of minerals in the soil and agrotechnical methods of cultivation (Chaplin and Martin 1980, Prive and Sullivan 1994, Hargreaves et al 2008, Koumanov et al 2009). Moreover, the concentration of nutrients in leaf tissues may change during the vegetation period (John et al 1976).…”

Economics of primocane-fruiting raspberry production in lowland conditions

“…In Bulgaria, the information on the raspberry-crop water and nutritional regime is scarce and there is still a lack of knowledge concerning fertigation. The irrigation management, the spatial and temporal distribution of the root water uptake, the fertilizer type, the timing and the application doses were object of a nine-year study with the 'Lyulin' primocane-fruiting raspberry cultivar which was carried out at the Fruit Growing Institute in Plovdiv (Kornov et al, 2009(Kornov et al, , 2010(Kornov et al, , 2011(Kornov et al, , 2013Koumanov et al, 2006Koumanov et al, , 2009. The aim of this publication is to evaluate the economic efficiency of the technology for raspberry production in lowland conditions.…”
