Abstract: Pulses, also known as grain legumes are next to cereals in terms of agricultural importance and have been considered best option for diversification and intensification of agriculture across the globe. Therefore, present investigation was planned to evaluate the response of Mungbean varieties to foliar application of iron. The experiment consisted of 16 treatment combinations of four varieties ie. IPM 02-3, SML-668, RMG-492 and RMG-62 and five iron application practices i.e. Control, 0.5% FeSO4 spray at branching, 0.5%FeSO4 spray at flowering and 0.5% FeSO4 spray at branching +flowering and replicated three times. Results revealed that RMG 492 recorded significantly higher plant height, dry matter accumulation, number of branches and leaf area index over RMG 62, IPM 02-3 and SML 668 at 50 DAS and at harvest. Among the iron spray, foliar application of 0.5% FeSO4 at branching+ flowering stage significantly increased the plant height, dry matter accumulation, number of branches and leaf area index plant height of mungbean over control at 50 DAS and at harvest stages. Likewise, RMG 492 produced significantly higher grain yield (1518 kg/ha) over SML 668 (1221 kg/ha), IPM 02-3 (1311 kg/ha) and RMG 62 (1406 kg/ha) with a quantum increase of 297, 207 and 112 kg/ha, respectively. The corresponding increase in terms of percentage was 24.3, 15.7 and 7.9 per cent, respectively. Foliar spray of 0.5% FeSO4 at all the stages significantly increased the grain yield of mungbean. Application of 0.5% FeSO4 at branching + flowering recorded an increase of 28.5 per cent, over control. The variety RMG 492 recorded the maximum straw yield of 3076 kg/ha which was significantly higher over RMG 62 (2864 kg/ha), IPM 02-3 (2695 kg/ha) and SML 668 (2515 kg/ha) representing quantum increase of 561, 381 and 212 kg/ha, respectively. Application of 0.5% FeSO4 spray significantly increased the straw yield of mungbean. The highest value of straw yield was recorded with of 0.5% FeSO4 spray at branching and branching + flowering stage which was 15.6 and 20.8 per cent higher over control. Based on the results of this experiment, it may be inferred that Mungbean variety RMG 492 was found most suitable for obtaining higher productivity. Similarly, foliar application of 0.5% FeSO4 at branching + flowering stage was observed as the most effective for enhancing growth and yields of Mungbean.
