Application of usar tod masala as well as gypsum could increase the green biomass production
by 50 % over sole urea fertilizer application. Brachiaria mutica could produced maximum green
(54.3 and 73.2 t ha-1) as well as dry (12.77 and 13.17 t ha-1 ) biomass which was followed by
Leptochloa fusca (39.5 and 45.8 t ha-1 green and 11.06 and 12.82 t ha-1 dry), Setaria sphacelata
(36.4 and 46.4 t ha-1 green and 8.00 and 10.20 t ha-1 dry ), Chloris gayana (30.2 and 38.9 t
ha-1 green and 6.64 and 8.55 t ha-1 dry), Sorghum sudanensis (16.3 and 28.8 t ha-1 green and
4.23 and 7.48 t ha-1 dry) and Panicum maximum (7.8 and 26 t ha-1 green and 1.95 and 6.5 t
ha-1) dry biomass production respectively in the investigating years 1997-98 and 1998-99. The
increase in the yield attributing characters also significantly increase in the grain as well as straw
yield of rice due to growing of Brachiaria mutica (3.8 and 3.9 t ha-1 grain and 5.2 and 5.3 t ha-
1) yield of straw which was followed by Leptochloa fusca (3.6 and 3.7 t ha-1 grain and 4.8 and
4.9 t ha-1) straw yield of rice and Chloris gayana (3.2 and 3.4 t ha-1 grain yield of rice and 4.5
and 4.7 t ha-1 straw yield in 1999 and 2000 respectively. The application of amendments for
reclamation of salt-affected soils and residual effects of forage grasses increased the grain yield
of rice by 70 % due to gypsum, 55 % due to usar tod masala and 14% due to prilled urea
fertilizer application over control (without addition of amendment or chemical fertilizers
