Background: Cowpeas thrive in poor dry conditions, growing well in soils up to 85% sand. This makes them a particularly important crop in arid, semidesert regions where not many other crops will grow. As well as an important source of food for humans in poor, arid regions, the crop can also be used as feed for livestock. Cowpea is primarily used in the form of dry seeds, fodder, green pod, green manure, and cover crops. Objectives: Effects of boron levels and plant growth regulators on growth, yield and economics of cowpea (Vigna unguiculata L.). Methods: The field experiment was conducted in Zaid season of 2021, at crop research farm of Department of Agronomy at Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj in North Eastern plains of Eastern Uttar Pradesh, under Randomized block design comprising of 10 treatments with different combination of boron levels and plant growth regulators which are replicated thrice. Conclusion: Based on the above findings it can be concluded that the application of boron and plant growth regulators performs effective and improves the Plant height, Dry weight, No of Branches, No of pods per plant, No of seeds per pod, Test weight, Seed yield and stover yield of cowpea, the findings are based on research conducted during a single season, they may be repeated for further confirmation.
