Irrigation and nutrients are most prerequisite factors for crop growth and development. Any imbalance in supply of water or nutrients may leads to poor crop performance and lower production. Therefore there is need to optimize irrigation and fertigation practices to sustain the fenugreek growth, yield and also better seed quality. In the present study drip irrigation at three levels (I1 - 25 % CPE, I2- 50 % CPE and I3 - 75 % CPE) and fertigation at four levels (F1 - 25 % RDF, F2 - 50 % RDF, F3 – 75% RDF and F4 - 100 % RDF) were studied in split plot design with three replications. Results reveled that drip irrigation at 75 per cent cumulative pan evaporation recorded highest growth and yield but it was on par with drip irrigation at 50 per cent cumulative pan evaporation (CPE) (I2). Drip irrigation at 50 per cent CPE (I2) recorded plant height of 75.6 cm, biomass accumulation (7,507.45 kg/ha), number of pods per plant (55.68), number of seeds per pod (7.88), pod length (4.9 cm), test weight of seeds (16.16 g) and seed yield (1,793.8 kg/ha). Whereas, in case of fertigation application of fertilizers at 100 per cent recommended dose of fertilizers (RDF) (F4) was recorded highest plant height and it is at par with fertigation 75 per cent RDF. However there were no significant differences were found in case of biomass production, number of pods per plant and seed yield. But fertigation at 100 per cent recommended dose of fertilizers resulted in higher seed protein (30.67 %) content. Water use efficiency was optimum in drip irrigation at 50 per cent CPE (I2) which is at par with drip irrigation at 25 per cent CPE (I1). It is concluded that drip irrigation at 50 per cent CPE and 50 per cent RDF as fertigation in fenugreek crop is optimum for higher seed yield and water use efficiency.
