Effect of sowing dates and seeding density on yield of wheat (Triticumm aestivum L.)
Journal Title: International Research Journal of Applied and Basic Sciences - Year 2014, Vol 8, Issue 7
Abstract
In wheat cropping system, farmers usually use normal wheat seed (100 kg ha-1) even under late planting. The negative effect of late sowing may be compensated by the subsequent increase in seed quantity.A study was undertaken to determine the effects of sowing dates and seeding density on growth and yield of wheat, variety N-85-5 in Iran. The trial was laid out with split plot arrangement having three replications during 2011-12. Three sowing dates i.e. Dec 21, Dec 30 and Jan 29 were in main plots, whereas tow wheat seeding density (350 and 500 plant/m2) were in sub plots. Results shows that higher number of grain spike, spike weight, 1000-grain weight and biological, grain yield with seed rate of 500 plant/m2. Similarly, sowing wheat on Dec21 produced the highest number of spike, spike weight, 1000-grain weight and biological, grain yield, which subsequently decreased with successive sowing dates.
