Modes of Culture: 50 days after planting the weeds are removed, keeping the pulses and other species. After approximately 180 days, depending upon the growth of the pulses, a new whole cleaning is done, leaving the weeds as a green fertilizer rich in nitrogen and potassium. Once a week the sugar cane is irrigated with a sprinkler system with a 20 mm blade.
