Monitoring of colorado potato beetle (Leptinotarsa decemlineata Say) sensitivity to insecticides
(Bulgarian Journal of Agricultural Science, 2013)
Sensitivity of two field populations of Colorado potato beetle (Leptinotarsa decemlineata Say.) - CPB (Vilovo and Čurug) adults to insecticides were determined in 2008 and 2012. Bioassay was performed using screening test ...
Response of different beans against common bacterial blight disease caused by xanthomonas axonopodis pv. Phaseoli
(Bulgarian Journal of Agricultural Science, 2012)
Common bacterial blight (CBB) in beans, caused by the bacterium Xanthomonas axonopodis pv. phaseoli (Xap), is an economically important disease worldwide which reduces crop yields and seed quality. Since there is no ...
Chemical variability of inedible fruit parts in pepper varieties (Capsicum annuum L.)
(Bulgarian Journal of Agricultural Science, 2013)
Pepper is an important vegetable widely used for human nutrition and industrial processing. It is used dried or fresh in various pharmacological preparations and as a source of biologically active compounds, such as ...
Photosynthesis and water use efficiency relations to yield of ten pepper varieties (capsicum annuum l.)
(Bulgarian Journal of Agricultural Science, 2012)
Search for new pepper variety with high yields, along with tools for prediction of pepper yield is constantly on the way. The link between net photosynthesis measured at specific phase. of pepper development and crop yield ...
Effect of thinning date and genotype on some phenological and quality characteristics of sugar beet seed
(Bulgarian Journal of Agricultural Science, 2013)
We analyzed the effect of thinning date and genotype on some phenological and quality characteristics of sugar beet seed produced by the over wintering method in two calendar years. Experiments were conducted in sugar beet ...
Diversity of weed flora in wheat depending on crop rotation and fertilisation
(Bulgarian Journal of Agricultural Science, 2012)
The paper analyses weed flora in wheat depending on crop rotation and fertilisation in a twenty-year period. In both studied periods (1990 and 2010) the total of 49 weed species were determined on different variants of ...
