Productivity of pulses is low for these crops are mostly grown on marginal and sub-marginal soils with little or no application of fertilisers. Majority of pulse-growing regions of India are low in Zn content, and therefore, application of 1.5-5 kg Zn/ha alone or over and above the recommended doses of NPKS to different pulse crops are necessary. The application of Zn results In the enhancement of grain yield and quality. Genetic variability for response to applied Zn has been noticed among different cultivars of pulses. The Zn requirements of crops are low. Zn application may be performed once in a year, alternate years or after 3-5 years depending on Zn status of the soil. Several methods of Zn application viz., soil, seed coating, spraying, etc. have been found effective In correcting the Zn deficiency of the plants. Among different methods of application, soil application of ZnSO4 is most common and sometimes, it provides more beneficial results than other sources of Zn. Soil application of Zn depends on nutrient status in soil, soil types, rainfall, organic matter addition and cropping systems. The Zn applied in one crop of the system generally takes care of the Zn requirements of the succeeding crop too.
