Description A field experiment was conducted on clay loam soil of the Agricultural
College Farm, Bapatla to assess the soybean [Glycine max (L.) Merrill] need for
zinc and iron with and without vermicompost during rabi, 2007-08. The
treatments consisted of three vermicompost levels (application of NPK alone,
combined application of NPK and vermicompost and application of
vermicompost alone) assigned to main plots and six micronutrient levels (no
micronutrient application, soil application of ZnSO4@ 25 kg ha-1, foliar
application of ZnSO4 @ 0.2%, foliar application of FeSO4 @ 0.5%, soil
application of ZnSO4 & FeSO4 @ 25 kg ha-1 and 10 kg ha-1. and foliar
application of ZnSO4 @ 0.2% and FeSO4 @ 0.5%) assigned to sub-plots
arranged in split-plot design and the treatments were replicated thrice.
In general, growth parameters like plant height and drymatter
accumulation were found to be the highest with the combined application of
NPK and vermicompost over NPK alone and vermicompost alone. No
significant differences were observed among vermicompost levels for number
and dryweight of nodules at 30 DAS; however, at 60 DAS the highest number
and nodule dryweight was recorded with integrated application of NPK and
vermicompost. Days to 50% flowering was not significantly influenced by
different treatments. Yield attributes, seed and haulm yield of soybean were the
highest with combined application of NPK and vermicompost over NPK alone
and vermicompost alone. Quality parameters like protein, zinc and iron
contents in seed were the highest with the integrated application of NPK and
vermicompost. Oil content of soybean was not significantly influenced by the
vermicompost levels. Uptake of nutrients and available nutrients in soil at
harvest were superior with combined application of NPK and vermicompost.
The maximum plant height, highest drymatter accumulation, more
number and dryweight of nodules were recorded with the soil application of
ZnSO4 and FeSO4. But, it was comparable with foliar application of zinc and
iron. No significant difference was observed for days to 50% flowering with
micronutrient levels. The highest number of pods, more test weight and
increased seed and haulm yield were recorded with soil application of ZnSO4
and FeSO4 over no micronutrient application and it was on a par with foliar
application of zinc and iron. The maximum protein content was recorded with
the soil application of ZnSO4 and FeSO4 .Conversely, oil content was not
significantly influenced by micronutrient levels. No significant difference in
NPK uptake and available NPK content of soil at harvest were found with
micronutrient levels, whereas, zinc and iron uptake by plant and seed were
significantly influenced by micronutrient levels. The highest zinc and iron
uptake was recorded with foliar application of zinc and iron and it was on a par
with soil application of zinc and iron.
Thus the present study indicated that application of NPK along with
vermicompost was found significantly superior to NPK alone and
vermicompost alone in increasing growth parameters, yield attributes, yield and
quality parameters. Soil application of ZnSO4 + FeSO4 increased growth
parameters, yield attributes, yield and quality parameters, and was comparable
with foliar application of zinc and iron. Combined application of NPK and
vermicompost along with zinc and iron either by soil application or by foliar
application significantly increased the seed yield of soybean compared to no
micronutrient application, whereas, integrated application of NPK and
vermicompost without micronutrient application was found to be similar in
increasing the growth, yield and quality parameters as that of combined
application of NPK, vermicompost along with micronutrient application.
