Abstract:
... The hundred year history of East Malling Research Station (EMRS) is reviewed from a personal perspective: In March 1913, Kent fruit farmers in the Southeast of England founded the Wye College Fruit Experimental Station. In 1920, the newly formed ‘Kent Incorporated Society for the Promotion of Experiments in Horticulture’ took over East Malling (as a site independent from Wye College) „with offices ...

Abstract:
... Models predicting photosynthetically active radiation (PAR) in heterogeneous canopies are an essential component of process-based weed dynamics models for assessing integrated weed management strategies. Most existing light availability models either consider only homogeneous canopies or are based on optical principles that are too complex for multi-annual and large-scale simulations required for ...

Abstract:
... Large scale adoption of input intensive rice–wheat cropping system in the centrally located Jalandhar district of Indian Punjab has led to over-exploitation of ground water resources, intensive use of chemical fertilizers and deterioration of soil health. To overcome these shortfalls, in the present study, agricultural area diversification plan has been generated from agricultural area and crop ro ...
