Cím:Fruit-bearing shoot characteristics of apricot cultivars in Hungary / Dren, G.; Thurzo, S.; Szabo, Z.; Nveki, J.; Racsko, J.; Holb, I. J.
Dátum:2006
ISSN:0567-7572
Megjegyzések:During the winter of 2004/2005, the flower bud density of four types of fruit-bearing shoots and the changes in frost resistance were studied on 11 apricot cultivars. Significant differences were measured among the cultivars in the number of flower buds. Based on the results, the bud density of shorter shoots is generally higher, but this is not valid for all cultivars. There were fivefold and almost twofold (1.85) differences in bud density among cultivars on shoots shorter than 10 cm and longer than 40 cm, respectively. The ratio of bud densities of different types of shoots also ranged between wide boundaries. The frost resistance of the cultivars was examined by artificial freezing. The highest damage was obtained on ♭Robada', which had the highest flower bud density. At the end of the winter, the damage due to natural frosts was also assessed. The shoots of 10-20 cm length were the least damaged.

Cím:Profitability and regional differences of irrigated sweet corn (Zea mays conv. saccharata) in Hungary / I. Ehret-Berczi, A. Kiss, E. Vári, F. Apáti, Sz. Németh

Megjegyzések:The cultivated agricultural area is 5.3 million hectares, which is 57.5 per cent of total area of country, providing outstanding opportunities for agriculture. The last decades show more frequent and more severe impact of drought, yet the area with outdoor irrigation system is only 144 thousand hectares, but no more than 100 thousand hectares are irrigated by producers. The increase of irrigable areas would be a huge development opportunity for Hungarian open field plant production. This is even more important in light of the expected negative impacts of climate change in the region. For this reason, the Government treats the spreading and sustainable development of irrigation management, protection and utilization of water resources as a priority, which is confirmed by the 1744/2017. (X. 17.) Government Regulation of Irrigation Development Strategy. As part of the Strategy, the Hungarian Chamber of Agriculture undertook to carry out a survey in the potential areas with most potential for implementation of irrigation development, i.e. current delimited irrigation network impact area based on 68 surface water bodies. This affected 1.2 million hectares and 43 026 producers. The producers want to irrigate 388.5 thousand hectares from the 1.2 million in the future, of which 120 thousand hectares are currently an area with irrigation system, whereas 268.5 thousand hectares of new irrigation demand appeared. In the largest area of vegetables in the future, producers want to irrigate sweet corn (33.6 thousand hectares). From these 33.6 thousand hectares 9.8 thousand hectares have already had completed irrigation system and 23.8 thousand hectares of new irrigation demand. We made the estimation based on producers` responses, that the future irrigation purpose what economic benefits can be realized. We calculated in detail the profitability indices of sweet corn. Production value of dry cultivated sweet corn was between 1.2-1.9 thousand EUR, while it changed between 1.5-2.78 thousand EUR/hectare in case of irrigated sweet corn production. We accounted of different soil conditions and drought zones to the investigation of regional differences of sweet corn`s profitability, and we calculated with different years and the territorial variation of yields.

Cím:Brown rot blossom blight and fruit rot incidences of apricot in two different geographical regions in Hungary / Holb, I. J.; Drén, G.; Szabo, Z.; Racsko, J.; Thurzo, S.; Nyeki, J.
Dátum:2006
ISSN:0567-7572
Megjegyzések:The aim of our two-year study was to assess the incidence of brown rot blossom blight and fruit rot caused by Monilinia laxa in 2003 and 2004. Assessments of incidence were made on cultivar ♭Bergeron' (susceptible to brown rot) in a flatland and a hilly growing area (at Cegléd and Gönc, respectively). In both locations, plant protection was performed according to the integrated fruit production guidelines and small untreated plots were set up for each cultivar in both years. In 2003, when weather conditions were dry and hot, brown rot incidence was low (less than 10%) on both blossoms and fruits. Monilinia laxa did not cause significantly different blossom blight and fruit rot at the hilly (Gönc) area compared to the flatland, even in untreated plots. However, in 2004, when spring and summer weather conditions were wet and cold, incidence reached 95% for blossom blight and 33% for fruit rot in the untreated plots. Blossom blight incidence was 1.5-2 times higher in the flatland area compared to the hilly growing area. During the blooming period of apricot, two (at the flower-bud stage and at full bloom) and three (at the flower-bud stage, at full bloom and at petal fall) fungicide applications were necessary for successful control at Gönc and Cegléd, respectively. The difference between the two orchards was due to the fact that blooming started one week later in the hilly region (at Gönc) than in the flatland region (at Cegléd); therefore, the critical weather period coincided only partially with blooming in the orchard in the hilly region. Fruit rot incidence was similar in both regions, since the amount and distribution of rainfall were similar during the fruit-ripening period.

Cím:Effect of auxin-synergistic preparation (Nevirol 60 WP) on flowering date and yield of sour-cherry and European plum fruits in Hungary / Racsko, J.; Holb, I.; Szabo, Z.; Thurzo, S.; Dren, G.; Nyeki, J.
Dátum:2006
ISSN:0567-7572
Megjegyzések:The authors investigated the reaction of four sour-cherry (♭Debreceni bőtermő', ♭Érdi bőtermő', ♭Meteor korai', ♭Újfehértói fürtös') and three European plum cultivars (♭Besztercei', ♭Cacanska Lepotica', ♭Stanley') to an auxin-synergistic preparation (Nevirol 60 WP). Spray applications were carried out at the 50% flowering stage of the trees. Application of the regulator increased the longevity/viability of the stigma and supported better pollination. The date of the end of flowering was deferred 2.2 days on average in the cases of sour-cherry cultivars, and 1.0-1.5 days on European plum cultivars. The treatment resulted in a 27-35% increase in fruit setting on sour-cherry, and 15-24% on plums. In the case of the sour-cherry cultivars the ratio of clusters with high numbers of fruits (3-4 fruit/bunch) was increased. In accordance, the yield was enlarged by about 22% in the case of sour-cherry cultivars and 15% on European plum cultivars. The increase of yield was not in close corellation to increases of fruit setting in all cases, because some fruits shrivelled or dropped as a consequence of oversetting in certain cases. Fruit quality parameters were also studied, including fruit weight, fruit diameter, soluble solids and sugar contant.
