Abstract

The field experiment was conducted during Kharif season 2020 at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj to study about the “Effect of Nitrogen levels and Biofertilizers on growth and yield of Groundnut (Arachis hypogaea L.)” The experiment was laid out in Randomized Block Design, with Nine treatments which are replicated thrice. The treatment consists of three levels of nitrogen and biofertilizers viz T1 (10Kg N/ha+ Rhizobium), T2 (10Kg N/ha + PSB), T3 (10Kg N/ha+ Rhizobium+ PSB), T4 (15Kg N/ha+ Rhizobium), T5 (15Kg N/ha+ PSB), T6 (!5Kg N/ha+ Rhizobium+ PSB), T7 (20Kg N/ha+ Rhizobium), T8 (20Kg N/ha + PSB), T9 (20Kg N/ha+ Rhizobium+ PSB), The maximum results showed in growth and yield attributing characters viz. plant height (102.19cm), dry weight (45.78g), nodules/plant (157.78), pods/plant (28.80), kernels/pod (2.07), seed index(47.06g), seed yield (2655.58 kg/ha), haulm yield (3587.20), harvest index (42.31) were recorded significantly higher in T9 (20 Kg N/ha +Rhizobium +PSB) while net returns (91858.24 Rs/ha) and B:C ratio (2.44) were also recorded in application of T9 was found to be more productive as well as economic.
