Cacopsylla pyri (Linnaeus, 1758) is the most significant and widespread pear pest. It attacks only, causing direct indirect damages. This study was conducted in order to evaluate efficacy of insecticide spinetoram control C. pyri. The experiment set up according EPPO methods, at locality Kula (Republic Serbia) a orchard (Williams variety). Spinetoram (250 g/kg a.i., WG) foliar applied amount 0....

Lettuce is a valuable leaf vegetable for well-balanced diet, since it rich in nutrient elements, has low calories and provides dietary antioxidants. Compared to soil-based cultivation, the hydroponic system an alternative associated with shortening of growing cycles reduction wasted water amount. The aim this study was analyze growth lettuce plants under soil cultivation systems, during three p...

Use of paclobutrazol is common strategy for inducing uniform and profuse flowering in mango. The possible mechanism by which paclobutrazol exert such responses are less understood. The present investigation was carried out to investigate possible role of polyamines and ethylene biosynthesis in the paclobutrazol induced floral induction in mango. Following paclobutrazol soil drenching applicatio...

Potassium (K) has a significant effect on wheat yield and quality. Owing to the limitations of irrigation production costs, soil-based applications potassium fertilizer are not performed in Loess Plateau China. In late growth stage wheat, deficiency occurs even under sufficient nitrogen/phosphorus (N/P) levels, so it is necessary supplement through foliar spraying. However, there few studies ap...

Artemisia pollen is an important allergen in Europe. In Poznań (Western Poland), three Artemisia species, A. vulgaris, A. campestris and A. absinthium, are widely distributed. However, the contributions of these species to the total airborne pollen are unknown. The aim of the study was to determine the flowering phenology and pollen production of the three abovementioned species and to construc...

The paper presents the results of a 2016–2018 study to determine effect share components in mixture and harvest date on weed infestation yield mixtures field pea with spring triticale. Two factors were studied experiment: proportion mixture: – clean sowing 100%, triticale 75% + 25%, 50% 50%, 25% 75%; harvesting date: flowering stage (BBCH 65), flat green pod 79). obtained allow us conclude that...

Precision phenotyping, especially the use of image analysis, allows researchers to gain information on plant properties and plant health. Aerial image detection with unmanned aerial vehicles (UAVs) provides new opportunities in precision farming and precision phenotyping. Precision farming has created a critical need for spatial data on plant density. The plant number reflects not only the fina...
