Effect of iron on seed germination, plant growth and nodulation in Vigna radiata R. Wilczek

This paper reports the effect of iron (FeSO₄.7H₂ O) as a micronutrient at 25, 50 and 100 ppm concentration on some growth and biochemical parameters of Vigna radiata. At 25 and 50 ppm concentration, a significant increase was observed in all parameters but at 100 ppm concentration an inhibitory effect was observed on some parameters
