Description The field experiment entitled, “Agronomical management of late sown wheat” was
conducted at Agronomy Research Farm of CCS Haryana Agricultural University, Hisar, during
rabi season of 2007-08. The experiment was laid out in randomized block design. There were
ten treatment combinations namely :(T1 )-dry seeding on15th December followed by irrigation,
(T2)-dry seeding with overnight soaked seed on15th December followed by irrigation, (T3)-dry
seeding with 25% higher seed rate on15th December followed by irrigation, (T4)-dry seeding
with overnight soaked seed with 25% higher seed rate on15th December followed by irrigation,
(T5)-dry seeding on 1st January followed by irrigation, (T6)-dry seeding with overnight soaked
seed on 1st January followed by irrigation, (T7)-dry seeding with 25% higher seed rate on 1st
January followed by irrigation, (T8)-dry seeding with overnight soaked seed with 25% higher
seed rate on 1st January followed by irrigation, (T9)-dry seed sowing on 1st January after pre
sowing irrigation on 15th December and (T10)-soaked seed sowing on 1st January after pre
sowing irrigation on 15th December.
The treatment T4 observed with highest number of seedling emergence and minimum
number of seedling was found in T5. The days taken to attainment of heading, anthesis and
physiological maturity were recorded significantly higher in 15th December sown treatments as
compared to 1st January sown treatments. The dry matter accumulation, LAI, LAD and CGR
were recorded significantly higher in T4 than all other treatments.
Among the yield attributing characters number of effective tillers/mrl was found highest
in T4 followed by T3 and minimum in T5. But, among all the treatments T4 observed with
significantly higher grain yield (4196 kg/ha) and biological yield (10359 kg/ha). Significantly
lower grain (2885 kg/ha) and biological yield (7426 kg/ha) were observed in T5 as compared to
all other treatments except T6 with which it was found statistically at par. The LAI, LAD, CGR,
RGR and NAR have shown highly significant and positive correlation among themselves and
with grain yield. Among the yield attributes number of effective tiller/mrl had significant
association (r = 0.97) with grain yield, biomass yield and straw yield of wheat also had
significant positive association (r = 0.99).
