Abstract: The effect of organic manures and super absorbent polymers on nutrients uptake and economics of soybean [Glycine max (L.) Merrill] was studied with eight different treatments replicated thrice with Randomized Completely Block Design (RCBD). The treatments were comprising of RDF alone, RDF with FYM at the rate of 3.0 t ha-1, RDF plus potassium polyacrylate @ 5.0, 7.5 and 10.0 kg ha-1, RDF plus pusa hydrogel @ 7.5 kg per hectare, RDF plus humic acid @ 3.0 kg ha-1 and RDF plus vermicompost at the rate of 3.0 t ha-1. The results revealed that, application of RDF along with potassium polyacrylate at 7.5 kg ha-1 was recorded to be significantly higher with respect to growth viz., plant height, number of leaves plant-1, total dry matter and yield parameters like seed weight plant-1, test weight, oil per cent and oil yield. The uptake of NPK and S was also recorded higher with above said treatment. Net returns and B:C ratio was higher with application of potassium polyacrylate at 7.5 kg ha-1 along with RDF.
