Abstract:
A field experiment was conducted to study the comparative performance of zinc in biofortified rice and their effect on yield attributes, yield and zinc concentration of rice at BAU farm, Sabour in Randomized Block Design replicated thrice during Kharif season of 2021-22. The variety used was Sabour Aaayush. The soil of the experimental plot was silt loam having pH 7.7, organic carbon 0.53%, Low in available Nitrogen (159.88 kg/ha), Phosphorus (26.94 kg P2O5/ha), Potassium (196.69 kg K2O/ha) and initial soil Zn-1.0 mg/kg of soil. The recommended dose of fertilizers i.e. 100-40-20 kg N- P2O5- K2O/ha was applied. In addition to these fertilizers 25 kg zinc sulphate was applied as basal and 0.5% zinc sulphate used as foliar spray at pre flowering and milking stage of rice.

In addition to these fertilizers 25 kg zinc sulphate was applied as basal and 0.5% zinc sulphate used as foliar spray at pre flowering and milking stage of rice.
The experimental results revealed that RDF (100:40:20)+25 kg/ha zinc sulphate as basal+0.5% zinc sulphate spray as foliar application at pre flowering and milking stage was the best treatment and recorded significantly better values for yield attributes (74.74 grains per panicles,270.33 panicles per m2, 30.18 g test weight),higher grain yield (4.96 t/ha) and higher concentration (30.9 and 91.8mg kg-1 grain and straw respectively) and uptake of Zn in grain (153.3 g ha-1) and in straw (455.2 g ha-1) of bio fortified rice than soil application alone and single spray of Zn and most other treatments. This study brought out that adequate soil application of Zn sulphate followed by its two foliar applications is the best approach.
