Farm size and agricultural productivity of nutritious foods: Evidence from Ethiopia

open access: yesJournal of Agricultural Economics, EarlyView.
Abstract Agri‐food systems are transforming quickly in Africa. An important issue in the transformation process of agricultural production is the role of small farms. While many authors have looked at this question, one aspect that has received little attention is the role of small farms in the production of nutritious foods, an important topic given ...

Population dynamics of stubby root nematodes (Trichodorus and Paratrichodorus spp.) associated with ‘Docking disorder’ of sugar beet (Beta vulgaris L.), in field rotations with cover crops in East England

open access: yesAnnals of Applied Biology, EarlyView.
This study evaluated the population dynamics of stubby root nematodes (SRN) in field rotations with cover crops and the subsequent effect of this rotation on sugar beet quality and quantity attributes. It was clear that the SRN densities under field conditions are influenced by multiple factors, such as the type of cover crops grown, soil disturbance ...

A methodology to optimize nitrogen management by accounting for the trade‐offs between crop yield, available nitrogen and potential nitrogen losses in lettuce

open access: yesAnnals of Applied Biology, EarlyView.
The combination of crop nitrogen (N) status indicators with empirical relations can improve N management. A critical curve of %Nc = 3.39 · DMP−0.22 was determined for lettuce. An integrated nitrogen nutrition index value of 1.09 was related to maximum relative dry yield. The optimal N supply (as total available nitrogen [TAN]) for maximum dry yield was
