Suggest any good lens for landscape photography?

I have Nikon D3100 dslr camera and nikon 18-55mm, 55-300mm lenses, but i'm not getting the best results with 18-55mm for landscape photography. My budget is 20k. Please guyz suggest any good lens.

Thanks in advance.

Added (1). And also suggest me any good macro lens for my Nikon d3100.

Added (2). Sorry i.e. In indian currency INR

20k? Go for the gusto… Get the AF-S NIKKOR 14-24mm f/2.8G ED for the landscape and the AF-S VR Micro-NIKKOR 105mm f/2.8G IF-ED for macro.

If you can't get good pictures with your 18-55, you won't be able to get good pictures with any other lens. Get a tripod and learn about hyper-focal distance.

It would be best if we knew what currency that 20K was but here are some nice wide angle lenses that would be great for landscape shots.

Wide angle lens? AF-S 10-24 mm lens

Macro? AF-S 105 mm f/2.8 lens AF-S 60 mm if you intend to be copying documents or other flat objects using a copy stand

If you are not getting good landscape results with 18-55mm then maybe you are not good enough…

Nothing good comes in 14000INR… Unless you go 2nd hand…

The first thing is to ask yourself what it is about your pics with the 18 to 55 that is wrong. Are they not sharp enough? Do you not get enough into the picture - you lose desirable parts from both ends of the picture? In that case get a wider-angle lens, say a 12mm, but that will not be cheap. You may have software in your computer that will allow you to stitch two or more pics together to get a wider angle - try that before spending serious money.

So first find out exactly what is not satisfying you before spending any money.

YOur equipment is not the problem. Make sure your lenses are clean and your camera is steady. Get extension tubes instead of a macro lens.

Tamron SP AF 17-50mm F/2.8 Di II LD Aspherical (IF) this will be best for landscape photography in your budget.

50mm will cost you about 5000-8000 rupees! And is suitable for landscape photography
