THE EFFECT OF NON-WOVEN PP FABRIC COVERS ON THE YIELDING AND THE FRUIT QUALITY OF FIELD-GROWN SWEET PEPPERS
2010
Michalik, Łucja
In recent years in Poland there has been an increasing interest in the field growing of sweet peepers, both among producers and consumers. Therefore, research should be conducted to select cultivars well adapted to less favorable temperature conditions and suitable for cultivation in the field, and to increase their yield. A field experiment was carried out in the years 2006–2008 in the Garden of the Research and Experimental Station of the University of Warmia and Mazury in Olsztyn to determine the effect on plant cover on the yield and the content of dry matter and organic compounds in sweet pepper fruit. In comparison with the control treatment (without protective cover), the use of non-woven PP covers increased the marketable yield of sweet pepper cv. Iga, Lena and Mira, and it decreased the marketable yield of cv. Zorza. Sweet pepper fruit in the control treatment had the highest average dry matter content. The use of non-woven PP covers contributedto dry matter accumulation only in the fruit of cv. Zorza. The fruit of sweet pepper plants grown without protective cover contained greater amounts of L-ascorbic acid. Non-woven PP covers had no effect on the concentrations of total and reducing sugars, which were highest (subject to cultivar and cultivation method) in 2007.
