Its dead. The main shoot died from too wet,too dry, too chilled for too long as a seed, or even too much peat in the potting mix you used.

Your best bet is to plant MANY Mango seeds- all you ate of a box of them,and you will quickly learn that vigor is wildly varied seedling to seedling. Keep the best,cull the rest.

Thanks a lot, i will continue to plant and try to get better results.

Actually it could be over watering since i watered it everyday.

The soild is sheep manure compost.

It may try to reshoot from the embryo within the seed, if given warmth and good conditions.
