This fact demonstrates the importance of the organic matter biotic factor for disease control.The efficient control of bacterial wilt with the incorporation of pigeon pea and crotalaria to soil could be due to the fact that the decomposition of organic matter occurred in the infested soil, while the incorporation of already decomposed organic matter (Ecofertil and Cofertil) did not stimulate soil microbial activity. The main symptom of the disease is wilting characterized by gradual, sometimes sudden, yellowing, withering and drying of leaves followed by drying of entire plant or some of its branches (Singh, 1973).Such plants exhibit loss of leaf turgidity, interveinal clearing and chlorosis before death. <>
The seeding rate of pigeon pea depends on the desired plant density for a genotype (early, medium or late), cropping system (pure crop, mixed crop, or inter crop), germination rate of seed and mass of seed. In the latter, total carbohydrates were more in the root than in the shoot, while in the former, the opposite trend was observed.

The pigeon pea (Cajanus cajan), also known as pigeonpea, red gram, tur, or gungo peas in Jamaica, is a perennial legume from the family Fabaceae.Since its domestication in the Indian subcontinent at least 3,500 years ago, its seeds have become a common food in Asia, Africa, and Latin America. /Parent 2 0 R Fusarium wilt is one of the major yield and growth-limiting factors of pigeon pea. 15 and lowest in the most susceptible N.P. /MediaBox [0 0 612 792] McRae reported that the fungus spreads about 3m through the soil in one season. /Type /Page Wilt of pigeon pea 1.
