MINERAL NUTRIENT CONTENT VARIATIONS IN FODDER GRASS DUE TO USE OF URBAN SEWAGE WATER

S.T. Girishal and S. Urnesha

Abstract

Variation in the chemical components of Brachiaria mutica upon sewage water irrigation in three different pattern of irrigations were studied in the present work with two seasons. The components studied were silica, calcium, iron, sodium, Potassium, chloride and nitrogen with sewage water and normal water irrigation.All these components in plants were significantly increased when compared to the plants with normal water irrigation. However, the amount of increase was more with waterlogged conditions, followed by irrigated condition and the least increase was with dryland condition.Among the seasonal fluctuations, the concentration of these chemical components was more in the summer season than in the rainy season. The contribution of the urban sewage water for the increased concentrations of these chemical components are discussed in the present paper.
