The field experiments were conducted during kharif seasons of 2008 and 2009 at the research farm of RBS College, Bichpuri, Agra to study effect of phosphorus, manganese and growth regulator (NAA) on yield and uptake of nutrients by cowpea [Vigna unguiculata (L.) Walp]. Result of the experiment revealed that an application of phosphorus @ 60 kg/ha recorded significantly higher plant height (42.70, 44.30 cm), green foliage (178.50,181.50 kg/ha), dry matter yield (19.64, 20.52 q/ha), content N(1.12, 1.13 %) P (0.18, 0.19 %) K (1.34, 1.35 %) and Mn (1.19, 1.20 ppm) over the control. Similarly manganese level @ 10 kg/ha also recorded significant effect in increasing all these yields and chemicals composition parameters while NAA also @ (100 ppm NAA) levels of growth regulator was obtained higher growth yield and uptake nutrient by cowpea.
