A field experiment was conducted at Avikanagar during kharif seasons of 2010 and 2011 to
explore the possibility of improvement in productivity and profitability of mixed pasture inclusion of
dhaman grass (Cenchrus setigerus) and fodder legume as field bean (Dolichos lab lab), which were grown
in different row proportions (1 : 1, 1 : 2 and 2 : 1). Further, the nutrient management through organic
sources comprising of control, sheep manure @ 10 t/ha, vermicompost @ 3 t/ha and sheep manure@ 5 t/
ha+ vermicompost @ 1.5 t/ha were studied. The results of the study revealed that growth indices, green and
dry fodder yields, protein yield and available nutrients were influenced significantly by Cenchrus and
Dolichos in 2 : 1 ratio. The maximum increase in green fodder (13.98 t/ha), dry matter (4.22 t/ha) and
protein yield (84.3 kg/ha) were recorded in 2 : 1 row ratio of Dolichos and Cenchrus followed by 1:1 row
proportion. Overall, there was 23.52 per cent increase in organic carbon content under the same treatment
in comparison to initial soil status. The available N (9.18 and 15.48%), P (21.05 and 34.30%) and K (4.53
and 7.06%) were increased maximum in 2 : 1 row ratio of Dolichos and Cenchrus than other row ratios
(1:1 and 1:2). The net returns (Rs. 21,606/ha) and benefit : cost ratio (2.29) were the maximum in 2 : 1 row
ratio followed by 1 : 1 row ratio (Rs. 19, 860 and 2.17). Application of sources of organic manures (sheep
manure @ 5 tonnes/ha+vermicompost @ 1.5 t/ha) had produced higher green fodder (12.68 t/ha), dry
matter (4.43 t/ha) and protein yield (87.6 kg /ha). The organic carbon content of soil was also improved by
38.23 per cent higher with the application of both the sources of organic manures by half doses. The
available N (44%), P (39.7%) and K (27.37%) were reported remarkably better with both the sources of
organic manures applied by their half doses. Application of sheep manure @ 5 t/ha+vermicompost@ 1.5 t/
ha resulted in higher net returns of Rs. 23, 881/ha.
