Abstract:
A field experiment was conducted at Agricultural College Farm, Raichur, Karnataka, during Kharif 2016-2017 to studies on agronomic biofortification with zinc and iron on nutrient availability, uptake and yield in pearlmillet [Pennisetum glaucum (L.)] genotypes, the experiment was laid out in split plot design and comprised of two factors for study viz., Main plot and subplot treatments. Significantly higher availability of nitrogen, phosphorus and potassium (303.15, 30.58 and 286.91 kg ha-1) was recorded in the plots grown with genotypes G3: HFeZn-113 (high in Zn & Fe). Among micronutrient applications significantly higher availability of nitrogen, phosphorus and potassium in the soil the treatment with M7: Soil application of ZnSO4 @ 15 kg ha-1 and FeSO4 @ 10 kg ha-1 + Foliar application of 0.5 % ZnSO4 and FeSO4 (323.45, 35.50 and 318.12 kg ha-1) and also similar trend was followed by availability of zinc and iron. Significantly higher zinc and iron total uptake was recorded with genotype G3: HFeZn-113 (high in Zn & Fe) (172.12 and 1089.14 ppm, respectively). Similarly micronutrients application significantly higher zinc and iron total uptake was recorded with M7: Soil application of ZnSO4 @ 15 kg ha-1 and FeSO4 @ 10 kg ha-1 + Foliar application of 0.5 % ZnSO4 and FeSO4 (808.21 and 1143.19 ppm, respectively respectively). The genotype G3: HFeZn-113 (high in Zn & Fe) recorded significantly higher grain and stover yield (1721 kg ha-1 and 4437 kg ha-1, respectively). Among the micronutrient application significantly higher grain and stover yield was obtained in M7: soil application of ZnSO4 @ 15 kg ha-1 & FeSO4 @ 10 kg ha-1 + Foliar application of 0.5 % ZnSO4 and FeSO4 each (1904 kg ha-1 and 4611 kg ha-1, respectively) as compared to control.
