Nitrogen yield and nitrogen use of chickpea compared to pea, barley and oat in Central Europe
European agriculture suffers from a substantial deficit of protein sources forlivestock and the projected changes in agro-climatic conditions in Central Europeinclude a higher risk of drought. To address these challenges, the drought resistantlegume crop chickpea was compared with pea, barley and oat regarding its nitrogen(N) yield, protein yield and N use and utilization efficiency under Centr...
متن کاملNitrogen Fertilizer Management in Dryland Wheat Cropping Systems
Wheat is the most widely cultivated food crop in the world, which provides nutrition to most of the world population and is well adapted to a wide range of environmental conditions. Timely and efficient rates of nitrogen (N) application are vital for increasing wheat grain yield and protein content, and maintaining environmental sustainability. The goal of this study was to investigate the effe...
متن کاملNitrogen Fertilization Effects on Productivity and Nitrogen Loss in Three Grass-Based Perennial Bioenergy Cropping Systems
Nitrogen (N) fertilization can greatly improve plant productivity but needs to be carefully managed to avoid harmful environmental impacts. Nutrient management guidelines aimed at reducing harmful forms of N loss such as nitrous oxide (N2O) emissions and nitrate (NO3(-)) leaching have been tailored for many cropping systems. The developing bioenergy industry is likely to make use of novel cropp...
متن کاملRole of nitrogen content of pea (Pisum sativum L.) on pea aphid (Acyrthosiphon pisum Harris) establishment
The leaf nitrogen content is generally accepted as an indicator of food quality and as a factor affecting host selection by phytophagous insects. The alate pea aphids (Acyrthosiphon pisum Harris, Aphididae) were given a choice among non-nodulated pea plants (Pisum sativum L.) supplied with one of four nitrate-N levels (0, 3, 15 and 30 mM). When whole plants were exposed to aphids for 7 days, th...
