Abstract: Field experiment was conducted at Millet Breeding Station, Tamil Nadu Agricultural University, Coimbatore during 2015 and 2016 with the objective of Growth and yield of short duration Pigeon pea (Cajanus cajan L.) varieties under Drip fertigation system. The experiment was laid out in strip plot design with three replications. The main plot treatments were allotted with three varieties viz., Co (Rg) 7, APK 1 and VBN 3. The sub plot treatments comprised of three drip fertigation levels viz., 75%, 100% and 125% RDF (@ 25:50:25 kg NPK ha^-1) through WSF with Azophosmet and foliar spray of PPFM and drip fertigation at 100% RDF through WSF alone along with surface irrigation with conventional fertilizers. The effect of varieties and nutrient application methods (drip fertigation and soil application) the highest plant height, Leaf area index and dry matter production during Kharif 2015 and Summer 2016 DMP of (7042 and 6235 kg ha^-1 during Kharif 2015 and Summer 2016). The grain yield 1992 and 1758 kg ha^-1were significantly observed under drip fertigation with125% RDF through WSF with Azophosmet and foliar spray of 1% PPFM. Among the pigeonpea varieties, Co (Rg) 7 performed well compared to APK 1 and VBN 3 varieties.
