Abstract:
A field experiment was conducted in loamy sand soils of Tamil Nadu, India to optimize the nitrogen requirement to rice after sesame during the year 2004-2005 in two consecutive seasons in a Factorial Randomized Block Design (FRBD). The field was divided into 60 plots and in the summer season sesame was raised in 30 plots and the other 30 plots were kept fallow. In the next season (Kharif), the rice was raised in all the 60 plots of two different situations viz., with sesame as previous crop (Situation I) and without sesame as pervious crop (Situation II) with two rice cultivars viz., ADT 38 and KR 99001 and five levels of nitrogen viz., 0, 50, 100, 150 and 200 kg N ha-1. In rice, the plant height was significantly influenced by the situations in earlier stages and but not in the later stages. The number of tillers was found to be higher in situation II than in situation I in all the three stages studied viz., active tillering, panicle initiation and harvest stage. The same trend was noticed in number of productive tillers also. The variation in the situations did not bring any significant variation in grain yield, but slightly higher yield was noticed in situation II over situation I. Both ADT 38 and KR 99001 manifested higher yields at 150 kg N ha-1 in both the situations reveals the fact that this level of N, which is a recommended dose of N for medium and long duration rice, is sufficient for better growth and development of rice. The straw yield was comparable in both the situations.
