Enhancing Mungbean (Vigna radiata L.) Performance with Optimized Nitrogen and Sulphur Levels

An experiment was conducted to study the impact of nitrogen and sulphur levels on the performance of mungbean. The experiment consisted of two factors viz. nitrogen levels and sulphur levels. The nitrogen application included four levels viz., N1: RDN @ 30 kg N ha-1; N2: Foliar application of Nano-urea @ 2 ml/L of water at 20-25 DAS; N3: Foliar application of Nano-urea @ 2 ml/L of water at 40-45 DAS and N4: Foliar application Nano-Urea @ 2 ml/L of water at 60-65 DAS whereas Sulphur application included three levels viz., S0: 0 kg ha-1; S1:15 kg ha-1 and S2: 30 kg ha-1 which was applied through Gypsum. The results showed that application of N3 resulted in higher performance of Mungbean in terms of growth parameters viz., plant height, DMA and LAI, yield attributes and yield. This indicates the importance of applying nano urea at the optimal growth stage to meet the crop's nutrient demands during critical periods of development. Likewise, increasing sulphur levels from S0 to S2 showed a positive effect on crop performance, with the highest results observed at 30 kg sulphur ha-1 S2.
