Description The present investigation entitled “Effect of sowing time and seed rate in wheat (Triticum aestivum L.) under late
sown condition” was conducted during the winter season of 2013-14 at Farm of Krishi Vigyan Kendra Fatehabad of
Chaudhary Charan Singh Haryana Agricultural University, Hisar. The experiment consisted of five sowing times (Ist
week of December(2nd December), IInd week of December(9th December), IIIrd week of December(16th December),
Last week of December(23rd December) and Ist week of January(2nd January)) in main plots and four seed rates (100
kg, 112.5 kg, 125 kg and 137.5 kg/ha) in sub plots. 20 treatment combinations were tested in strip plot design with
three replications.
Dry matter accumulation, plant height was significantly higher when sowing was done on 2nd December
and increase in seed rates results higher dry matter accumulation. Delay in sowing resulted significant reduction in
number of days taken to 100% emergence, 50% flowering and maturity of wheat. However, higher seed rate failed
to produce any significance in phenophases.
Sowing on 2nd December was significantly superior to other sowing times in production of effective tillers,
earhead length, number of spikelets earhead-1, number of grains earhead-1 and 1000 grain weight. With each
successive level of seed rate from 100 kg/ha to 137.5 kg/ha, significantly enhanced effective tillers but failed to
produce any significance in other parameters .The grain, straw and biological yields of wheat were significantly
higher on 2nd December sowing. Among different seed rates, yield were found highest with the application of 137.5
kg/ha seed, which was at par with yield under 125 kg/ha seed rate.
Gross and net returns as well as B:C ratio was maximum under sowing on 2nd December, closely followed
by 9th December sowing, which was more economical to 23rd December and 2nd January sowing. In general, cost of
cultivation, gross return as well as net return increased with successive increase in seed rates from 100 kg/ha to
137.5 kg/ha. Highest B:C observed under 137.5 kg/ha seed rate, which was comparable with B:C ratio under 125
kg/ha seed rate.
