Abstract: The present investigation entitled “Effect of poultry manure conjugated with npk on soil properties, growth and yield attributes of clusterbean (Cyamopsis tetragonoloba l.) cv. radha desi” was carried out at the Soil Science Research Farm, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj, during the kharifi season of 2022. The area of Prayagraj district comes under subtropical belt in the South east of Uttar Pradesh, which experience extremely hot summer and fairly cold winter. The maximum temperature of the location reaches up to 46⁰C – 48⁰C May – June and seldom falls as low as 4⁰C – 5⁰C in winter December – January. The relative humidity ranged between 20 to 94 percent. The average rainfall in this area is around 1100 mm annually. Soil samples were taken from 0-15 and 15-30 cm soil depth randomly prior to tillage operations, air dried and passed through 2mm sieve. Then the composite soil sample was taken for mechanical, physical and chemical analysis. The experiment was conducted in 4x4 factorial randomized block design with four level of NPK and Poultry manure. The treatments were replicated three times and were allocated at randomly in each replication. On the basis of findings it is concluded that the treatment combination T₁₆ @105%NPK+@pm­30 t ha^-1 i.e, Treatment T₁₆ was found best result on growth and yield of cluster bean in comparison to other treatment combination. From the economical point of view, the treatment gave maximum C:B ratio is 1:29 Followed by treatment T₁₂ @105%NPK+@pm­0 t ha^-1 is 1:27. Since the findings are based on the research done in one of season further experiments with more than one season will help in better to study the effect of NPK and Poultry manure on growth and yield by cluster bean (Cyamopsis tetragonoloba L.) Cv. Radha Desi. The minimum bulk density (mg m^-3), particle density (mg m^-3), pH and EC dSm^-1 was noted in T₁₆ @105%NPK+@pm­30 t ha^-1 which was significantly superior over T₀ Control. Whereas the maximum pore space (%), organic carbon, available nitrogen (kg ha^-1), available phosphorus (kg ha^-1) and available potassium (kg ha^-1), was noted in T₁₆ @105%NPK+@pm­30 t ha^-1 which was significantly superior over T₀ Control.
