May 31 (Reuters) - ICE cotton futures closed mostly unchanged on Wednesday on favorable weather conditions for planting of the natural fiber.

"People are still worried about the size of the crop for the next year ... the weather for planting continues to be good," said Gabriel Crivorot, analyst at Societe Generale in New York.

"In India the monsoon I think it will be at normal for the first time in a while, so expectations for actually yielding the crop so far have been good."

Federal data released on Tuesday showed 63 percent of cotton crops were harvested in the United States by the week ended May 28, up from 52 percent in the previous week.

"Crop plantation is going on fine as there is plenty of water with rains expected in Texas," Peter Egli, director of risk management at British merchant Plexus Cotton.
