Abstract

A field study was conducted during rabi seasons of 2012-13 and 2013-14 to assess the effect of different fertility treatments and brassinosteroid on productivity and quality of fenugreek (Trigonella foenum-graecum L.). Results revealed that the significantly higher values of yield attributes, seed yield (2 245 kg/ha), haulm yield (5 236 kg/ha) and quality parameters (protein, sapogenin, diosgenin and galactomannan) were recorded with application of 100 % RDF over lower fertility levels. Dual inoculation of seed with Rhizobium + PSB gave significantly higher yield attributes, seed yield (2 085 kg/ha), contents and yields of protein (450.33 kg/ha), sapogenin (26.87 kg/ha), diosgenin (11.76 kg/ha) and galactomannan (593.69 kg/ha) over their sole application. Interaction of fertility levels and biofertilizers was also found significant in yield attributes and consequently in seed yield and yields of quality parameters. Application of 100 % RDF + dual inoculation, being on a par with 80 % RDF + dual inoculation, gave the highest seed yield (2 287 kg/ha), protein yield (513.52 kg/ha), sapogenin yield (30.32 kg/ha), diosgenin yield (13.21 kg/ha) and galactomannan yield (677.44 kg/ha). Foliar spray of brassinosteroid 0.50 ppm brought about significantly higher yield attributes, seed yield and quality parameters over water spray and BR 0.25 ppm, respectively. Thus, integration of 80 % RDF with dual inoculation and supplemented with foliar spray of brassinosteroid 0.50 ppm at 50 and 70 DAS is better for realizing higher yield and quality in fenugreek.
