Abstract. Crop phenology exerts measurable impacts on soil surface properties, biophysical processes and climate feedbacks, particularly at local or regional scales. Nevertheless, the response of to feedbacks as affected by sowing date in winter wheat croplands has been overlooked, especially during dormancy. The dynamics leaf area index (LAI), energy balance canopy temperature (Tc) were simula...

A sensitivity analysis of the responses of crops to the chosen production adaptation options under regional climate change was conducted in this study. Projections of winter wheat production for different sowing dates and cultivars were estimated for a major economic and agricultural province of China from 2021 to 2080 using the World Food Study model (WOFOST) under representative concentration...

Herbage yield of alfalfa (Medicago sativa L.) depends on forage management or environmental conditions that change C and N resource acquisition, and endogenous plants factors such as root organic reserves and number of active meristems. The aim of this work is to study the influence of two sowing dates in summer (12 July or 9 August), N fertilization (0 or 100 kg ha(-1)) and/or irrigation appli...

[Background] Wheat is the most important food crop, with largest planting area in world. However, production process, due to species degradation and occurrence of new diseases, antigens old varieties are lost, resulting reduced yield even no harvest. In order ensure stable increase wheat, need be updated time. By using different seasons places carry out additional generation breeding two...

Echium (Echium plantagineum L.) is an alternative oilseed crop in summer-wet temperate regions that provides floral resources to pollinators. Its seed oil is rich in omega-3 fatty acids, such as stearidonic acid, which is desired highly by the cosmetic industry. Seeds were sown in field plots over three years in western Minnesota in spring (early-sown) or early summer (late-sown), and flower ab...

poor wheat stand establishment is a major cause of yield loss, particularly in rainfed and poorly irrigated environments. seeds of eight wheat cultivars (triticum aestivum l.) including irrigated and rainfed varieties, belonging to three different climates of iran (hamedan as cold, karaj as temperate and sarpolzohab as warm climates) were primed using osmoprimig treatments through use of urea ,...

abstract in order to study the effect of sowing date and seeding rate on essential oil content and composition of chamomile (matricaria recutita l.) cv. presov, prepared from slovakia, an experiment was conducted. the experimental design was split-plot in the basic of randomized complete blocked design (rcbd) with three replications. main plots consisted of three sowing dates (6 nov, 5 mar, and...
