Agronomic package for hybrid rice cultivation

Yield stagnation or even a decline has been observed in many rice-growing areas, particularly in potentially highly productive areas. To increase rice production, a few rice hybrids have been developed and released in recent years in India. To exploit the crop's full heterotic potential, it is essential to develop a package of optimum production practices for hybrid rice cultivation. We therefore attempted to study nursery management, seeding densities, seedling ratios, transplanting dates, N management, and hybrid response at several locations under the coordinated rice improvement program.
