Biofortification of Coriander (Corianderum sativum) Variety with Sulphur and Zinc for Higher Productivity

The present study was aimed to examine the effect of two varieties (RCr-436 and RCr-435), four levels of sulphur (0, 20, 40 and 60 kg S/ha) and four levels of zinc (0, 2.5, 5.0 and 7.5 kg Zn/ha) making 32 treatment combination under split plot design with three replications. Results showed that significantly increased dry matter accumulation and seed (1409 kg/ha), stover yield, nitrogen, sulphur, zinc concentration, essential oil content, oil yield, protein content and net returns (Rs 39396/ha) were obtained with coriander variety RCr-436 as compared to vareity RCr-435. Whereas, coriander varieties RCr-435 recorded significantly higher plant height as compared to RCr-436. The variety RCr-436 recorded 13.1 and 24.2% higher seed yield and net returns as compared to RCr-435. Sulphur application at 40 kg/ha increased significantly higher plant height, dry matter accumulation, seed (1406 kg/ha), stover yield, nitrogen, sulphur, zinc concentration, essential oil content, oil yield and protein content and net returns Rs 39175/ha over control and 20 kg S/ha. The sulphur at 40 kg/ha registered 20.8 and 7.5% higher seed yield and 39.0 and 12.7% more net returns over control and 20 kg/ha, respectively. Significantly increased higher plant height, dry matter accumulation, seed (1436 kg/ha), stover yield, nitrogen, sulphur, zinc concentration, essential oil content, oil yield, protein content and net returns( Rs 39309/ha) were obtained with 5.0 kg Zn/ha over control and 2.5 kg Zn/ha. Zinc application @5.0 kg/ha recorded significantly more seed yield by 30.3 and 10.5 % and net returns by 35.2 and 10.4 %, respectively.
