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. |
