Abstract
A field experiment was conducted during Rabi 2022 at Crop Research Farm, Department of Agronomy, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj (U.P) to determine the “Influence of Bio-fertilizers and Plant geometry on growth, yield and economics of field pea (Pisum sativum L.)”, The soil of experimental plot was sandy loam in texture, nearly neutral in soil reaction (pH 8.0), low in organic carbon (0.62 %), available N (225 kg/ha), available P (38.2 kg/ha) and available K (240.7 kg/ha),to study the response of plant geometry (20x20 cm,30x10 cm,40x10c m) with the combination of biofertilizers such as, rhizobium (20 g), PSB (20 g) and rhizobium (20 g) + PSB (20 g). The experiment laid out in RBD with 10 treatments each replicated thrice .the results showed that treatment 9 recorded significantly higher plant height (44.57 cm), maximum number of nodules/plant (7.12), higher plant dry weight (15.32 g), maximum number of pods/plant (20.13), maximum number of seeds/pod (4.00), higher seed index (18.57g), higher seed yield (1243.67kg), maximum straw yield (2656.21kg), higher harvest index (32.93%), maximum gross returns (1,19,838), maximum net returns (85,504) and highest Benefit cost ratio of (2.49) was recorded.
