Understanding how nutrients accumulate and change throughout the developmental stages according to BBCH scale can be a very effective technique for developing fertilization programmes high-quality, marketable grape production. Accordingly, macro- micronutrient concentrations at different growth were analyzed two commercial cultivars, viz., “Anab-e-Shahi” “Perlette”, by using an extended scale. ...

This article presents the results of a field experiment investigating energy efficiency grain produced by semi-dwarf genotype winter triticale at different levels agricultural inputs. The production was evaluated in two low-input and high-input cultivation practices that differed rate nitrogen fertilizer (split application) disease control. inputs associated with low were determined to be 14.5 ...

Biological efficacy of rapeseed spray oil against twospotted spider mite (Tetranychus urticae Koch) on cucumber, against European red mite [Panonychus ulmi (Koch)] on apple, green peach aphid (Myzus persicae Sulzer) on pepper and pear psylla [Cacopsylla pyri (L.)] was evaluated in seven field and three greenhouse trials at eight localities in Serbia during 2005-2008. The efficacy of rapeseed sp...

Knowledge about the fungal spores most abundant in the atmosphere of a vineyard is of great use since it allows development of prediction models of the spore concentration, and therefore application of phytosanitary treatments only when high levels of fungal propaguls are detected. In this study the concentration of phytopathogenic spores is related with the different phenological stages of the...

The berry size is one of the most important fruit traits in grapevine breeding. Non-invasive, image-based phenotyping promises a fast and precise method for the monitoring of the grapevine berry size. In the present study an automated image analyzing framework was developed in order to estimate the size of grapevine berries from images in a high-throughput manner. The framework includes (i) the...

Sensor- and satellite-based determination of nitrogen uptake provides critical data in site-specific fertilization algorithms. Therefore, two basic noncontact measurement methods (sensor satellite) were investigated winter wheat, their precision was evaluated this study. Nitrogen at four characteristic growth stages (BBCH 31, BBCH 39, 55, 65) determined using algorithms based on sensor satellit...

The role of preparations supporting plant growth is mainly to reduce the harmful effects various stress factors on plants and ensure high yields good quality. This experiment compared effect mineral stimulator Tytanit® biological preparation Effective Microorganisms (EM) physiological biochemical activity, as well yield common bean (Phaseolus vulgaris L.). photosynthetic pigments, free proline ...
