Description Field experiment was conducted at MRS, Hebbal, University of Agricultural
sciences Bangalore to study the Effect of different organic sources of nutrients on
green forage production of perennial grasses during August-2007 to March-2008 with
the objective of increase in green forage production of perennial grasses. The
experiment was laid out in factorial RCBD in sandy loam soil.
Different perennial grasses like hybrid napier, guinea grass and green panic and
various organic manures like water hyacinth compost, sewage sludge, domestic sludge
and poultry manure at the rate equal to the recommended dose of NPK and compared
with recommended practice.
Hybrid napier was recorded significantly higher green forage (45.2, 38.7, 42.5
and 38.9 t ha-1) and dry forage (12.8, 10.3, 11.6 and 11.9 t ha-1) respectively at first,
second, third and fourth cutting as compared to guinea grass and green panic.
Recommended dose of NPK recorded significantly higher green forage (73.9,
74.4, 75.3 and 74.3 t ha-1) and dry forage (21.4, 21.5, 21.0 and 23.0 t ha-1) yield at first,
second, third and fourth cutting respectively, where as application of poultry manure
during second, third and fourth cutting (i.e., 73.5, 74.4, and 73.8 t ha-1 green forage
and 21.2, 20.6 and 22.5 t ha-1 dry forage yield respectively) was found on par with
recommended dose of NPK, besides increased the plant height, number of leaves per
tiller, number of tillers per plant, leaf area per plant and quality parameters of grasses.
From the economic analysis, the highest B: C ratio was noticed in hybrid napier
+ sewage sludge (1.85), followed by hybrid napier + poultry manure (1.68) and hybrid
napier + recommended dose of NPK (1.43) and lowest (- 0.35 and -0.51) was reported
in guinea grass + domestic sludge and green panic +domestic sludge respectively.
