Abstract

To study the impact of nitrogen and iron on growth and yield attributes of rabi safflower, an experiment was carried out in 2020-21 Crop Research Form of SHUATS. The treatments consist of three levels of nitrogen soil application and three levels of iron foliar spray, experiment was laid out in randomized block design with nine treatments each replicated thrice. The result showed that viz., plant height (108.43 cm) and was recorded significantly higher with application of 50 kg/ha N + 0.3% iron foliar spray. Whereas, number of branches per plant (21.88), was recorded significantly higher with application of 50 kg/ha N + 0.6% iron foliar spray. The significantly higher dry weight (35.37 g/plant) and crop growth rate at 40-60 DAS (9.26 g/m2/day) was observed in 50 kg/ha N + 0.5% iron foliar spray treatment. Number of seeds per capitulum (22.18), seed yield (1427.7 kg/ha), stalk yield (3695.2 kg/ha) was recorded significantly higher with the application of 50 kg/ha N + 0.6% iron foliar sp

Conclusion

It was concluded that, on the basis of present study application of 50 kg/ha N + 0.6% iron foliar spray recorded significantly maximum number of branches per plant (21.88), number of seeds per capitulum (22.18), seed yield (1427.7 kg/ha) and stalk yield (3695.2 kg/ha) respectively. These findings are based on one season; therefore, further trails may be required for further confirmation.
