EFFECT OF WATERLOGGING ON GROWTH, YIELD AND NUTRIENT CONTENT OF DIFFERENT GRASSES

An experiment was conducted during 1993-94 and 1994-95 to study the pr oduction potential of grasses under different waterlogging conditions. The highest total green-forage and dry-matter yields were obtained in para grass (Brachiaria mutica Stafp) followed by nandi grass [Setaria sphacelata (Schum.) Stapf & Hubbard ex Moss] and napier-bajra hybrid 6. Highest total green forage and dry-matter yields were obtained in 5 0-100 cm (deep) waterlogging, followed by below SO cm (shallow) depth of waterlogging. Available N, P and K content in soil was more under d eep compared with shallow waterlogging condition. The chemical composi tion of grasses indicated higher content of N, CP, P, K, Ca and Mg in Setaria sphacelata than Brachiaria mutica under both deep and shallow depths of waterlogging.
