Effect of different potassium fertilizers suitable for use in organic farming systems on grass/clover yields and nutrient offtakes and interactions with nitrogen supply

, 2004
In organic farming systems, fertilizing materials can be used when potassium (K) deficiency is shown, but such systems are dominantly nitrogen (N) limited and this is likely to affect crop utilization of K. The supply of K to grass/clover from a range of

Sustainable Productivity Growth in Agriculture: The Role of Shifts in R&D Investments and Technology

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT The objective of the paper is to evaluate the long‐term prospects of sustainable productivity growth linked to plausible assumptions on public agricultural R&D investments as the key productivity driver. Second, it investigates the role of changing R&D focus from yield maximization to input saving technologies (fertilizers and pesticides). The

Glucosinolate and Isothiocyanate Profiles in Different Varieties of Raphanus sativus Seed via Multivariate Data Analysis

AgriFood: Journal of Agricultural Products for Food, EarlyView.
Through HPLC–MS/MS analysis and multivariate statistics, raphani semen (RS) varieties with high functional components were screened. The white raphani semen “Xuebawang” was identified as ideal for further study due to its high bioactive content: glucoraphenin (9010.27 mg/100 g), glucoraphanin (1027.76 mg/100 g), sulforaphane (66.14 mg/100 g), and ...
