Crop science literature and Bradford law

Tripathi, Harish Kumar; Sen, B K


An attempt has been made to test whether crop science literature follows Bradford law. The dataset comprised 10,100 papers indexed in Indian Science Abstracts and CAB Abstracts during the period 1965-2010. A ranked list of journals has been prepared and Leimkuhler test was conducted. The list of core journals is provided. The dataset does not follow Bradford law even with Leimkuhler formulation. The crops covered are rice, wheat, barley, maize, sorghum and millets. Possibly combining of data for six crops together and cumulating of data of every fifth year deviated the dataset from Bradford law of scattering.
