| dc.description.abstract | The experiment was conducted at research field and laboratory in the Department of
Crop Physiology and Ecology, Hajee Mohammad Danesh Science and Technology
University, Dinajpur, during the period of December 2016 to May 2017 to study the
effects of sulphur and irrigation level on the growth and yield of groundnut. The
experiment was laid out in a split plot design with three replications. The experiment
comprised of two sets of factors such as A: Three sulphur doses such as, S1= 20 kg
sulphur per hectare, S2 = 30 kg sulphur per hectare and S3 = 40 kg sulphur per
hectare; B: three irrigation levels like, I1 (30 mm irrigation), I2= (50 mm irrigation)
and I3 (70 mm irrigation) in total life span of the crop. Result revealed that S2 (30
kg/ha S) took highest days to attain germination, flowering, anthesis and pegging
while the S1 (20 kg/ha S) took lowest days for the above characters. Plant height,
number of leaves per plant, number of branch per plant, plant height, root length,
branch number, number of nodules, dry weight per plant, total chlorophyll content
and moisture retention capacity, relative leaf water content, number of mature pod
per plant at harvest, number of immature pod per plant, total number of pod per
plant, pod weight per plant at harvest, pod weight per plot and biological weight per
plot were highest in S2 (30 kg/ha S) while the above characters were lowest in S1
(20 kg/ha S). Crop growing with I3 irrigation took highest days to attain germination,
flowering, anthesis and pegging while I1 took lowest days for the above characters.
Plant height, number of leaves per plant, number of branch per plant, plant height,
root length, branch number per plant at harvest, number of nodules per plant at
harvest, dry weight per plant, total chlorophyll content, moisture retention capacity,
relative leaf water content, yield attributes and yield were highest in I3 irrigation
while the above characters were lowest in I1 irrigation. Most of the above parameters
were significantly influenced by the interaction of sulphur and irrigation in the
present study. Most of the characteristics showed their superiority in S2I3 while the
most of the characteristics were lowest in S1I1. Highest pod yield was obtained from
the interaction of S2I2. Finally, it can be concluded that combination of S2 (30 kg/ha
S) with I3 (70 mm irrigation) was the best treatment for groundnut production. | en_US |
