Influence of biofertilizers along with inorganic source of nitrogen and phosphorus on growth, seed yield and quality of fenugreek (Trigonella foenum-graecumL.)

Abstract

A field experiment was conducted at Hisar (Haryana) during the years 2012–13 and 2013–14 to study the response of biofertilizers and inorganic source of nitrogen and phosphorus on fenugreek variety Hisar Sonali with 16 treatment combinations in factorial RBD with three replications. The soil of the experimental field was low in organic carbon, available nitrogen, medium in phosphorus and high in respect to available potassium. Application of 60 kg N and 50 kg P2O5 per hectare gave significantly higher plant height, branches per plant, pod length, pods per plant, and seed, straw and biological yields as well as standard germination percentage over 50 kg N and 40 kg P2O5 per hectare. Combined inoculation of seed with Rhizobium and PSB and their sole application significantly gave higher plant height, branches per plant, pod length and seeds per pod. Whereas pods per plant and seed yield were recorded with combined inoculation of seed with Rhizobium and PSB, which were higher over their individual application and control.
