ired, in pure stands at about 9¡V22 kg/ha for rows, but sometimes it is broadcast. Seed germinate in about 2 weeks. Quite frequently (in India) pigeon pea is grown mixed with other crops or grown in alternate rows with rows of sorghum, groundnuts, sesame, cotton, pineapples, millets or maize. For pure crops pigeon pea should be sown 2.5¡V5 cm deep in rows 40¡V120 cm by 30¡V60 cm. When sown as a mixture, it should be sown in widely spaced rows ranging from 1.2¡V2.1 m depending on the associated crop. About 3¡V4 seeds may be planted in each hill, and later thinned to 2 plants per hill. Plants show little response to fertilizers, e.g., mixed plantings with millet in India showed negative response to N. For the first month, pigeon pea shares the intercultivation of the main crop. In the tropics, 20¡V100 kg/ha phosphoric acid are recommended. S, with or without P, can significantly increase seed yield and nitrogen fixation. Early cvs start podding in 12 week!
s but maturation requires 5¡V6 months. Late cvs require 9¡V12 mos. The crop may be ratooned for forage or let persist for 3¡V5 years. Seed yields drop considerably after the first year, and disease build-up may reduce stand
