Effect of irrigation scheduling with drip irrigation and nitrogen levels on growth and yield of wheat (Triticum aestivum L.)

Abstract

A field experiment was conducted at the Regional Research Station, Anand Agricultural University, Anand, Gujarat during rabi season of 2015-16. The experiment comprised of eight treatment combinations with four irrigation schedules under drip irrigation(0.6, 0.8 and 1.0 ADPEF and conventional method) and two levels of nitrogen (100% and 75% RDN). The field experiment was laid out in a split plot design with four replications. The growth and yield attributes were significantly higher in irrigation scheduled at 1.0 ADPEF as compared to rest of the treatments but it remained at par with 0.8 ADPEF. Irrigation schedules showed similar response for grain and straw yield. Varying nitrogen levels had non-significant effect on growth and yield attributes except for spike length and number of spikelets spike-1 where, significantly higher spike length and spikelets spike-1were observed with 100% RDN. Grain and straw yields of wheat were not influencedbynitrogen levels.
