Effect of Different Irrigation Method and Fertigation Level on Yield of Potato (Solanum tuberosum L.) under Western Rajasthan Condition

A field experiment was carried out at Precision Farming Development Centre, Agricultural Research Station, S.K. Rajasthan Agricultural University, Bikaner, India during 2017-18 to 2019-20 in potato (Solanum tuberosum L.) crop. The experiment comprising two fertigation level (75 percent recommended dose of fertilizer and 100 per cent recommended dose of fertilizer) and three irrigation methods (drip irrigation, micro sprinkler and flood irrigation).The spacing of plants were maintained 45 x 30 cm. The 25 t ha-1 FYM and NPK @ 150:100:100 kg/ha were applied in the crop. The experiment was laid out in a factorial randomized block design with three replications. Based on three year pooled data, it is found that the drip irrigation gave significantly higher yield (28.06 t ha-1) followed by micro sprinkler and flood irrigation method and among fertigation levels 100 % RDF gave maximum yield of (25 t ha-1) but it was at par with 75% RDF treatment.
