By the beginning of August, the elephant grass is very tall, two months after planting. Two varieties of grass are grown on this farm: the pilot green elephant grass and the traditional elephant grass. They were planted on the same day, but the green elephant grass is much taller. The yield is 15 kilogrammes for each four square metres.
