Abstract:

World over micronutrient deficiency is gaining an important notice that threatens human life. Selecting genotypes on the basis of higher yield and higher bioavailable zinc in grains as well as straw is required to simultaneously address Zn malnutrition in humans and animals besides satisfying the food demand. Attempts were made to screen various pearl millet (Pennisetum glaucum) genotypes for high zinc efficiency in potentially Zn deficient calcareous soil (zinc: 0.750 mg kg-1) with mineral Zn fertilization in a greenhouse experiment during 2016-17 in the Department of Soil Science and Agricultural Chemistry, Tamil Nadu Agricultural University, Coimbatore, India. Eighteen pearl millet genotypes were tested at two levels of Zn (0 mg Zn kg-1 and 10 mg Zn kg-1) in sandy clay loam soil (Vertic Ustropept). Results of the experiment revealed that the genotypes differed significantly in dry matter yield and zinc concentration. Based on the zinc use efficient indexing, genotypes were classified as efficient, inefficient, responsive and non-responsive. Among the genotypes studied, CO 9, GHB 744, Pioneer, MYS 86M84, MYS 86M86 and MYS 70428 were identified as most Zn efficient and responsive genotypes.
