Please suggest some plant species which are more economic to present scenario for the altitude range of 800 -1500 m. Fruit, seed, timber etc. will be useful for farming?
Rajni Kant Thakur , I believe that within this altitude range, the cultivation of temperate fruit trees such as peach trees, some cultivars of apple, pear, walnut and some in natura citrus cultivars can be viable, with good quality and profitability.
Hi Rajni, you should take a look at the FAOSTAT website. You might be able to select some countries and take a look at their agricultural output for this answer, or download a giant dataset and select countries based on their latitude to group data ( http://www.fao.org/faostat/en/#home )
