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...

چکیده به منظور مطالعه ارتباط صفات کمی و کیفی مؤثر بر عملکرد دانه کنجد در تیمارهای تغذیه­ای با کودهای شیمیایی، زیستی و نانو و تحت تنش خشکی، آزمایشی به صورت اسپلیت پلات فاکتوریل در قالب طرح پایه بلوک­های کامل تصادفی با سه تکرار انجام شد. فاکتورهای آزمایشی شامل رژیم­های آبیاری به صورت قطع آبیاری در مراحل مختلف رشدی براساس معیار BCH، آبیاری کامل و قطع آبیاری در BBCH 75 و 65، سه نوع کود نیتروژنه شا...

This research examined the effectiveness of zinc foliar fertilizers. Two winter wheat varieties, GK Pilis and Zvezdana, were tested in a Zn-limited meadow chernozem soil. Crop yields chlorophyll concentrations leaves growing seasons 2020/2021 favorable weather conditions 2021/2022 drought conditions. In experiment, three treatments carried out with monozinc fertilizer concentrated 12% (w/v) sul...

Chestnuts (Castanea spp.) are ecologically and economically important forest fruit trees. They cultivated for their nutritious nuts. To select varieties to be in chestnut orchards, phenology needs considered. In this work, we adapt the international BBCH system chestnuts by building on an existing phenological scale used some European countries these species. The proposed uses eight of ten prin...

Crop monitoring is important in precision agriculture. Estimating above-ground biomass helps to monitor crop vitality and to predict yield. In this study, we estimated fresh and dry biomass on a summer barley test site with 18 cultivars and two nitrogen (N)-treatments using the plant height (PH) from crop surface models (CSMs). The superhigh resolution, multi-temporal (1 cm/pixel) CSMs were der...

Botrytis cinerea is the cause of the most common disease in the Galician and Portuguese vineyards. Knowledge of the spore levels in the atmosphere of vineyards is a tool for forecasting models of the concentration of spores in order to adjust the phytosanitary treatments to real risk infection periods. The presented study was conducted in two vineyards, one located in Cenlle (Spain) and other i...

Since silicon regulates plant physiological and biochemical processes, it was hypothesized that foliar application could contribute to improving the quality of new potatoes. This paper analyzes effect (sodium silicate) on nutritional value sensory Silicon applied at dose 23.25 g Si·ha−1 or 46.50 once leaf development stage (BBCH 14–16) tuber initiation 40–41) twice, stages. Potatoes were harves...

The success of precision agriculture relies largely on our ability to identify how the plants’ growth limiting factors vary in time and space. In the field, several stress factors may occur simultaneously, and it is thus crucial to be able to identify the key limitation, in order to decide upon the correct contra-action, e.g., herbicide application. We performed a pot experiment, in which sprin...

An effective measure for controlling the most harmful wintering and winter weed species, such as Apera spica-venti, Galium aparine, Veronica persica, Consolida regalis, Capsella bursa-pastoris, Descurainia Sophia, Vicia villosa, etc. in wheat crops is autumn application of herbicides, especially early stages crop development, starting from seed germination stage, when it sensitive to their pres...

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...
