64kg tomato from a local plant in Nepal

A single plant of tomato in general can grow 2-4 kg of tomato in a season and its height is in a range of a meter.

But a farmer from western Nepal, Bhagaban Adhikari (Durali-7, Gorkha) has grown a tomato plant that can grow more than a muri (local measure equivalent to about 64kg) of tomato in a season. The plant is also more than 5 m in height. The farmer hopes to grow twice the amount soon as the height of the plant is still increasing.

You might say: with science, anything is possible. There are new technology like hybrid farming and fertilizers. But the farmer claims that he has never used any fertilizer or chemicals in the plant. (source)
