To be honest, I've not had such great experience with working with those effects as is. You can go into filter>filter editor, select dark and glow, click on 'add effect' and add various effects, then within some effects, you can change various settings. To give you an idea try this, add turbulence, then in effect parameters, move the slide bar in standard deviation while you look at your object.
As far as I understand you are experiencing the bounding box issue of the built in filters.
Filters are rendered on a predefined area relative to the object's bounding box. It is accessible in the filter editor's filter general settings where you can increase the filtered area.
If the area is large enough, you won't see those unexpected edges clipping the gradient.
Other "brute-force" solution would be grouping the object to be filtered with a larger invisible rectangle for example and applying the filter to the group -instead of the object within the group.
To clarify a bit on the technical background:
the filtered area is set in the percentage of the original bounding box.
However the filter is using a gaussian blur filter primitive, which is also percentage based -but where 100% blurring means an infinite "spread".
It is a common issue with blurring based filters that the effect would show on a larger area than what's set. Unfortunately the blurring size is not based entirely on the blurred object's bounding box, but on it's proportions too and a fitting filtered area size would need adjustments most of the times.
Contrary, the blurring slider in the fill and stroke panel also creates a filter, but somehow the developers managed that to readjust the filtered area size automatically.

I apply an effect Dark and Glow to the object and it does not work correctly.
I want the gradient to be smoother
sorry for my English

To shorten and clarify: Select object, open Filters > Filter editor. Select tab 'Filter General settings'. Modify the coordinates for the area.
I understood. Thank!
