Response of raspberry (Rubus idaeus L.) on soil mulching and foliar nutrition with manganese

Abstract

Raspberry is one of the most important species of fruit plants in Poland. The consumer usefulness and processing of fruits determined the taste and chemical composition. The raspberry fruits contain many valuable and important for human health ingredients. Furthermore the raspberries have a very high value of beekeeping. The main determinants of achieving a high yield and high biological value are a good supply of plant in the macro- and micronutrients and properly prepared soil.The aim of the study was to determine the response of raspberry on the soil mulching and foliar nutrition with manganese. In the study were included the following factors: I) type of bedding: black foil, black agri-woven, pine bark, wheat straw, soil without bedding – control; II) foliar nutrition with manganese and without foliar nutrition. Yield of fruits, weight of 100 fruits, length of shoots, fruiting terms and the number of harvests were specified. It was found that the soil bedding in the raspberries rows had no significant effect on the plant yielding, weight of fruits, length of shoots and the number of harvests. Foliar nutrition with manganese had a significant negative impact on the yield of raspberry fruits and their mass. While the foliar nutrition of plants had a significantly positive impact on the growth of raspberry shoots.
