ABSTRACT
Fenugreek is important legume seed spice which can grow with less amount of nutrients particularly nitrogen. But fenugreek is moisture loving crop and grows continuously if water is provided. But ideal irrigation and fertigation dose is most crucial for optimizing irrigation and fertilizer level and also achieving better uptake, use efficiency and residual soil nutrient content. Hence experiment was conducted at ICAR-National Research Centre on Seed Spices, Ajmer, Rajasthan during winter season of 2015-16 to find the effect of drip irrigation and fertigation on soil nutrient status and nutrient use efficiency of fenugreek. From the experiment it was found that residual soil nutrient content was significant this influenced the uptake of nutrients by fenugreek crop. Among nutrient uptake potassium is only element shows significant variations and it was highest in drip irrigation at 80 % cumulative pan evaporation (CPE) (64.0 kg/ha) and 100 % CPE (63.4 kg/ha) recorded higher uptake and both are on par. I4F1-drip irrigation at 100% CPE + Fertigation at 50% recommended dose of fertilizers (RDF) is shown highest nitrogen use efficiency (138.6 kg kg-1), phosphorus use efficiency (115.5 kg. kg-1) and potassium use efficiency (153.9 kg.kg-1). This study clearly indicates that 75 % fertigation dose and 80% drip irrigation level is most ideal in terms of residual soil nutrient status. To get better use efficiency application water at higher level and fertigation at lower level is most appropriate.
Key words: Fenugreek, fertigation, uptake, nutrient use efficiency
