Growth and yield attributes of wheat (Triticum aestivum L.) as influenced by lateral spacing with drip irrigation and nitrogen levels

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 drip lateral spacing (60, 80, 120 cm and conventional method) and two levels of nitrogen (100% and 75% RDN). The field experiment was laid out in split plot design with four replications. The growth and yield attributes were significantly higher in lateral spacing at 60 cm as compared to rest of the treatments but, they remained at par with 80 cm lateral spacing. Varying nitrogen levels had non-significant effect on growth and yield attributes except for number of spikelets spike-1 where, significantly higher spikelets spike-1were observed with 100% RDN. Non-significant influence of nitrogen levels was found on grain and straw yields.
