Residual effect of organic nutrients on growth and yield of hybrid napier (Pennisetum perpureum X Pennisetum americarnum) VAR. CO-4

Abstract

At present-day, wide requirement for environment friendly agriculture for the production of quality fodder to meet the nutrition demand of livestock. Efforts are ongoing for the sustainable way of fodder production with organic fertilizers from natural resources to enhance the production of important fodders. In this regard an experiment was conducted to define the effect of different organic manure on the growth yield and nutritive value of Hybrid napier (Pennisetum perpureum X Pennisetum americarnum) var. CO-4 . This experiment was designed in a Randomized Complete Block Design with three replicates. Treatments were control (Farm Yard Manure(FYM)(25Kg/ha) (T 1), Goat manure (30 t ha -1)and Farm Yard Manure(25Kg/ha) (T 2), Poultry manure (30t ha -1) and Farm Yard Manure (25Kg/ha )(T 3), Cattle manure (30 t ha -1) and Farm Yard Manure(25Kg/ha )(T 4). These were applied as basal and topdressing application of manure in this experiment and their performance was recorded once in three weeks. Analysis of Variance was performed to define significant difference among treatments (p < 0.05). Results revealed that plants grown in Poultry manure (30 t ha -1) incoporated with Farm Yard Manure(25Kg/ha) (T3 ) showed significantly (p < 0.05) better performance in the measured growth parameters viz. plant height(145cm), leaf area(9000cm2), number of tillers (38), while the lowest performance was observed in control (T1) at 11 WAP( weeks after planting). Further the results of this study revealed that relatively higher total dry matter(189.61g/plant) and nutrition composition viz crude protein(18.49%), Ash content(16.78%),crude fiber(39.4%) ,Ether extract (7.75%) was obtained from the plants treated with poultry manure and FYM (T3) followed by T4,T2 whereas the lowest drymatter yield(52.7g/plant) and nutrition composition was observed in control(T1). Therefore, it could be concluded that the poultry manure combined with FYM can be used to enhance the growth and nutritive value of Hybrid napier (Pennisetum perpureum X Pennisetum americarnum) VAR. CO-4.
