MORPHOLOGY AND YIELD
OF SOYBEAN GROWN ON ALLOPHANIC SOIL AS INFLUENCED BY SYNTHETIC ZEOLITE
APPLICATION
Abstract:
Our objective
was to assess the effect of synthetic zeolite application on morphology,
yield and yield components of soybean grown on allophanic soils. A
greenhouse experiment was carried out using three zeolite levels and
three soils (two allophanic and one paddy) with two soybean cultivars.
One determinate (Enrei, [MG] 1V) and indeterminate cultivar (Harosoy
[MG] 11) were grown in pots on April 20th and harvested on 15th
September at the Faculty of Agriculture, Ehime University, Matsuyama,
Japan during 2007. Zeolite levels of 0, 20 and 40 (g) were used to
determine the growth behavior of soybean cultivars. Different
morphological parameters including grain yield were significantly
affected by various zeolite levels and soil type. Maximum leaf area and
plant height were obtained from 40 (g) zeolite applications with KnP and
KyP allophanic soils. Harosoy grew taller than Enrei. Yield and yield
contributing attributes were affected significantly by zeolite levels
and soil type. Both cultivars gave highest grain yield at 20 (g) zeolite
applications and thereafter, the grain yield declined. Application of 20
(g) zeolite applications favored most of the yield contributing
characters that contributed maximum grain yield at this level of zeolite
application. The allophanic soils gave similar trend of increase in both
morphological and yield components parameters of soybean cultivars. A
decrease in morphological and yield components were observed, when
soybean were grown on a paddy soil with zero(g) zeolite application.
Enrei cultivar out yielded Harosoy at all levels of zeolite application
and soil type.
