Unlike the apple farmers, mangrove owners in Uttar Pradesh are facing a problem of plenty with a bumper crop driving prices down. But that's not just because of a glut. Says R.K. Tomar, a senior scientist at the Mango Research Institute in Malihabad, UP, "The quality of the mangoes this year has been very poor." He attributes this to the lack of nutrition provided to the trees. "Once these trees are heavily loaded (with fruit), they require excess nutrition. The farmers here have practically no knowledge of this." The institute has decided to go in for field demonstrations in the next flowering season. "For if this continues, the day is not far when mango farmers will fail to give fruit of good quality," justifies Tomar.
