Abstract:
The objective of the present study was to evaluate the
effect of zeolite application levels and allophanic soil on seed germination
and vigor of soybean cultivars grown under natural green house environment.
Seeds of two soybean cultivars (Enrei, [MG] 1V) and Harosoy [MG] 11) were
produced in thegreenhouse from three zeolite application levels
(0, 1 and 2%) and three soil (two allophanic and one paddy) at the Faculty
of Agriculture, Ehime University, Japan during summer, 2007. Brown (mature)
pods were harvested, threshed and all shriveled and abnormal seeds were
removed before determining germination and other vigor tests. Zeolite
applied at the rate of 1 and 2% improved germination and vigor of the
seed increased linearly (R2 = 0.72) as compared to control
treated plots (0%). Seeds obtained from two allophanic soils (KyP and
KnP) gave similar trend of increase in germination and vigor as compared
to a Paddy Soil. Among the vigor tests, accelerated aging, electrical
conductivity and seedling dry weight provided the best estimate of seed
vigor for the two soybean cultivars, both for ranking seed lots quality
and predicting field emergence. Seeds of Harosoy were more sensitive to
high temperature stress than seeds of Enrei and accelerated aging test
was more responsive in categorizing seed lots as compared to standard
germination. Among cultivars, Enrei gave maximum germination and showed
more vigor than Harosoy. Present findings support theresults
of experiment by demonstratingthat zeolite application to
soybean crop improves germination and vigor of soybean seeds. KyP and
KnP allophanic soils showed its potential for fertility and availability
of nutrients for plant growth and development as compared to paddy soil.
