Abstract

The study presents a comprehensive overview of seed testing procedure techniques designed explicitly for sunnhemp (Crotalaria juncea L.) var ADT 1, an essential leguminous plant exploited for its versatile uses in agriculture and various industries. The seed testing procedure comprises a systematic approach to evaluate the quality, viability and germination potential of sunnhemp seeds, which is crucial for ensuring successful crop establishment and yield optimization. The seed testing procedure was highlighted, viz., test weight determination, sample size estimation, purity assessment, standardization of germination media, temperature requirement for germination, and determination of first and final counts. The experiment results revealed that the submitted sample size could be 700g. In comparison, the working sample size was 70 g and the minimum standards for the pure seed and the inert matter percentage were 98 % and 1.5 % respectively. In the seed germination test, paper medium with a roll towel registered a maximum germination percentage (96 %) and vigour index (2146). Similarly, 30 oC temperature was registered as the maximum germination percentage. Based on this result, the first and final count was fixed as 3rd and 10th days in sunnhemp var ADT 1. Thus, seed testing procedures contribute to advancement in evaluating sunnhemp seed quality, promoting sustainable agriculture and economic prosperity.
