Potential Foliar Chemicals for Enhancing Yield and Drought Tolerance in Leguminous Crops: A Review

In pulse crops, synchronized flowering altered the source-sink relationship due to rapid translocation of nutrients from leaves developing pods. Additional nutrition through foliar feeding plays a vital role in production by stimulating root development, nodulation, energy transformation, various metabolic processes and increasing pod setting, thereby yield. Many researchers are trying reduce transpiration losses, flower shedding maximizing productivity, application nutrient formulations growth regulators pulses. Thus, macro micronutrients is considered an efficient economical method supplementing part requirements moisture stress tolerance at critical stages. The PPFM (Pink pigmented facultative methylobacteria), when used as spray, it releases osmoprotectants (sugars alcohols) on surface plants increases chlorophyll content, photosynthetic efficiency makes drought ability plants. This matrix helped protect desiccation high temperatures. Whereas potassium spray also enhances mitigating harmful effects translocation, maintaining water balance filling. Further, Salicylic acid endogenous regulator phenolic nature, which regulates physiological mitigate stress, acts chelate for phosphorous uptake, grain Pulse wonder decreases shedding, yield up 20% offers tolerance.
