Effect of liquid and solid bio-fertilizers (Rhizobium and PSB) on growth attributes, yield and economics of fenugreek [Trigonella foenum-graecum L.]

Abstract

An experiment was conducted during rabi, 2015 at Agronomy Instructional Farm, C.P. College of Agriculture, Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar, to study the “Integrated nutrient management in fenugreek [Trigonella foenum-graecum L.]’’ under North Gujarat condition. Almost all the growth attributes of fenugreek such as plant height (cm), number of branches per plant, number of root nodules per plant and weight of fresh nodules per plant (mg) as well as seed and straw yield were recorded significantly higher by application of 75% RDF + Rhizobium + PSB liquid formulation as soil application (T7) followed by T3 than other treatments. But plant population and harvest index was not affected significantly due to different treatments. The higher net return and BCR was accrued with treatment T7 (75% RDF + Rhizobium + PSB liquid formulation as soil application) followed by treatment T3. The lowest net realization and BCR was noticed under treatment T10 (75 % RDF).
