Abstract:
A field experiment was conducted during rabi season of 2017-18 and 2018-19 at the Rajasthan College of Agriculture, Maharana Pratap University of Agricultural & Technology, Udaipur. The aim of this study was to compare line sowing of wheat to Furrow Irrigated Raised Bed (FIRB) and System of Wheat Intensification (SWI) sowing methods in combination of irrigation scheduling and agrochemical applications for growth and yield parameters. The result disclose that sowing methods had notable impact on growth and yield parameters. Higher plant height was recorded with line sowing with 1.0 IW/CPE ratio 1.0 and hydrogel 10 kg ha^-1 + salicylic acid 200 ppm. Higher flag leaf area was recorded under SWI sowing whereas, maximum total tillers was recorded under line sowing with higher level of irrigation and agrochemical application. The higher grain yield was recorded through FIRB sowing (4682 kg ha^-1) followed by line sowing (4421 kg ha^-1) and SWI sowing (3929 kg ha^-1). Straw yield was recorded notably higher grain yield with line sowing (6961 kg ha^-1) over SWI sowing (5573 kg ha^-1) and found at par with FIRB sowing (6916 kg ha^-1). SWI sowing recorded superior harvest index (41.3%) than line (38.8%) and FIRB sowing (40.3%). It may be assume that FIRB sowing is appropriate method for wheat in late sown conditions for getting higher yield. Irrigation scheduling at IW/CPE ratio 1.0 recorded superior yield and yield components compared to IW/CPE ratio 0.75. Application of hydrogel 10 kg ha^-1 + salicylic acid 200 ppm observed notable dominant values of grain, straw and biological yield over others and found at par with salicylic acid 200 ppm.
