Abstract

Field experiments were conducted at Agricultural College and Research Institute, Coimbatore during August to February of 2011-12 and 2012-13 to study the effect of drip irrigation, fertigation levels and frequencies on seed yield and nutrient uptake of pigeonpea. Three fertilizer levels (75 %, 100 % and 125 % recommended dose fertilizer (RDF) through water soluble fertilizer and conventional fertilizers), three irrigation levels (50 % computed water requirement of crop (WRc), 75 % WRc and 100 % WRc) and surface irrigation (IW/CPE ratio 0.6 with 100 per cent RDF through conventional fertilizer) were included as treatments in this study. Application of 100 per cent of RDF (WSF) once in 7 days along with 100 % WRc (T9) recorded significantly higher uptake of total nitrogen, phosphorus and potassium. The lowest plant nutrient uptake was recorded by surface irrigation with application of 100 % RDF (T14) applied as basal. The results revealed that application of nutrients through fertigation once in seven days with 125 % RDF (WSF) + irrigation 100 % WRc recorded higher total nutrient uptake (nitrogen, phosphorus and potassium) than surface irrigation with conventional fertilizer...
