Track 2-3-1: Integrated Nutrient Management for Soil Health and Effects on Quality of Production
Description
Napier Bajra Hybrid, cv PBN-233 is a inter-specific hybrid between Pennisetum glaucum × Pennisetum purpureum. It is an important fast growing multi-cut fodder crop and provides fodder from April to November. It is widely distributed in sub-tropical regions of Asia, Africa, southern Europe and America. Nitrogen (N) is a fundamental regulator of plant growth and its supply strongly influence plant growth. In general, the availability of the nutrients influences the quality of various crops. Due to this reason, nitrogen fertilizers were increasingly used in agricultural sectors around the world. Some researchers reported that forage quality increased with nitrogen fertilization but nitrogen use efficiency declined. The increase in nitrogen fertilization improved considerably nitrogen uptake and would contributed to large photosynthetic activity and synthesis of higher protein content. Forages with high concentrations of crude protein (CP) considered of high quality because feeding high protein forage cut down the need of supplementary protein. Generally, high protein forages are more digestible and provide more energy than low protein forages. CP content generally decreased with the advancement of the plant growth due to synthesis of structural carbohydrates with advancing plant age. The declined protein content concentration was also attributed to reduction in leaf to stem ratio with advancing age. Neutral detergent fibre (NDF) and acid detergent fibre (ADF) are regarded as good indicators of forage quality because of their negative relation to digestibility in animals. Low NDF containing forage preferred by animals than high NDF ones. High NDF content in forages not only decreased intake, but also reduces the availability of energy for higher milk production. Increased supply of nitrogen and other nutrients increased the protein content whereas decreased the NDF and ADF content. Therefore, an attempt was made to evaluate the effect of different nitrogen levels and sources on quality traits of Napier Bajra hybrid in different cuts.
