Abstract

A field experiment on agronomic biofortification in rice varieties through zinc fertilization under aerobic condition was carried out at Assam Agricultural University, Jorhat during autumn season of 2014. Among the Varities, Inglongkiri recorded significantly higher grain yield (21.09 q/ha) followed by Banglami (19.88 q/ha) under aerobic condition. Application of ZnSO4 @ 25 kg/ha + foliar spray @ 0.5% at 3 stages recorded the highest grain yield (21.46 q/ha) followed by application of ZnSO4 @ 25 kg/ha + seed priming with ZnSO4 (2%) (20.72 q/ha). The lowest grain yield was recorded in control treatment (16.47 q/ha). Highest grain Zn content (32.03 mg/kg) and Zn content of brown rice(without polish) (26.81 mg/kg) was noticed in Inglongkiri. Application of ZnSO4 @ 25 kg/ha as basal + foliar spray @ 0.5 % at three stages reveals significantly highest Zn content in grain (35.09 mg/kg) and brown rice (28.31mg/kg).
