Abstract: A field experiment was conducted during the kharif season of 2018-19 on sandy-loam soil at G.B. Pant University of Agriculture and Technology, Pantnagar, Uttarakhand, to study the “Performance of promising pigeonpea [Cajanus cajan (L.) Millsp] genotypes at different rates of fertilization in tarai region of Uttarakhand.” with an objectives to optimize the fertilizer dose for getting maximum yield per hectare and effect on growth, yield attributes and yield of pigeonpea (Cajanus cajan (L.) Millasp). The experiment laid out in factorial RBD design keeping genotypes, viz. PA 421, PA 291, UPAS 120, and different fertility level management are control, 75% RDF, 100% RDF, 125% RDF at the time of sowing. The results obtained during course of investigation revealed that genotypes significantly influenced various growth parameters, yield attributing characters and yield. Genotype PA 421 was significantly superior over PA 291 and UPAS 120 in terms of yield attributing and PA 421 recorded 20.35% and 22.30% higher grain yield than PA 291 and UPAS 120, respectively. Among the fertility levels, 125% RDF recorded significant response to all the growth parameters at various growth stages which resulted in higher growth parameters, yield attributes and yield (2359 kg/ha) of pigeonpea compared to other fertility levels, 125% RDF was at par with 100% RDF. Hence, for achieving higher yield of pigeonpea, genotype PA 421 with the application of 100% RDF can be a better option in tarai regions of Uttarakhand.
