Conclusion
Sowing in March first week in combination with basal soil application of Co at 4 kg ha −1 and
foliar nutrition of K (1.25%) and B (0.2%) at flower initiation stage have immense potential to
intensify black gram growth and production. Even in case of delayed sowing, application of Co
in soil combined with K+B foliar spray can sustain optimum production potential of black gram
during spring-summer season in Eastern India.

The indiscriminate use of fertilizer degrades the soil health and pollutes the environment
(Galloway et al., 2008) while lower use of fertilizer is causing lower productivity. Hence,
fertilizer application must be optimized for sustainable higher yield, lower cost of cultivation and
a cleaner and environment-friendly production system (Zhang et al., 2015). Rice and maize are
