Effect of foliar application of zinc on biofortified rice (Oryza sativa L.)

A field experiment was conducted to study the comparative performance of zinc in biofortified rice and their effect on yield attributes, concentration at BAU farm, Sabour Randomized Block Design replicated thrice during Kharif season 2021-22. The variety used Aaayush. soil experimental plot silt loam having pH 7.7, organic carbon 0.53%, Low available Nitrogen (159.88 kg/ha), Phosphorus (26.94 kg P2O5/ha), Potassium (196.69 K2O/ha) initial Zn-1.0 mg/kg soil. recommended dose fertilizers i.e. 100-40-20 N- P2O5- K2O/ha applied. In addition these 25 sulphate applied as basal 0.5% foliar spray pre flowering milking stage rice. results revealed that RDF (100:40:20)+25 kg/ha basal+0.5% application best treatment recorded significantly better values for attributes (74.74 grains per panicles,270.33 panicles m2, 30.18 g test weight),higher grain (4.96 t/ha) higher (30.9 91.8mg kg-1 straw respectively) uptake Zn (153.3 ha-1) (455.2 bio fortified than alone single most other treatments. This brought out adequate followed by its two applications is approach.
