Abstract

The effects of seed provenance on daily seed germination, cumulative a seed germination and germination percentage of Jatropha Curcas L. was studied in the 2019 at the fruit and vegetable teaching and research Farm of Department of agricultural Science, Shehu Shagari College of Education Sokoto, Nigeria. The study area comprised of four senatorial zones of Sokoto state, Nigeria covering Sokoto Central Zone with Sokoto South, Wamakko, Kware and Binji Local Government Area. The Sokoto West Zone with Bodinga, Yabo, Shagari and Tambuwal Local Government Area. Sokoto East Zone with Gwadabawa, Goronyo, Isah and Sabon-Birni Local Government Areas. Seed accessions collected were dried properly and fumigated with nuval chemical and stored in polyethene bags. Uniform seed treatment was given to all the accessions prior to sowing, by soaking the seeds in water for 12 hours and subsequently sown directly on the field. They were laid out in a split plot design with three replications. Spacing was within the main plot, while seed germination was allocated the sub-plot. Data were recorded on percentage establishment, Daily seed germination, cumulative seed germination and germination percentage after the establishment count. Significant means were separated using the Duncan’s New Multiple Range Test (DNMRT). The highest daily germination (3.33a) was recorded at the seed accession (SE1), followed by the SE2 (P>3.00a) and the least being the SE4 (p<1.00C) whereas on the cumulative germination however, the seed accession at SE1 had the highest (P>17.67a) followed by those of accessions SC1 and SW4 (who were at par (P<14.33bc) and the least that form the accession of SC4 (P<5.33f). The seed accession at SE1 had the highest (P.>88.33a), followed by the SC1, and SW4 which were statistically at far (P.<71.67). Whereas the least being that at the accession SC3 (P.<46.67e). Consequently the seed at accession SE1 are therefore recommended for Jatropha cultivation in the semi-arid zone of Nigeria.
