Abstract

An experiment was conducted during 1999 and 2000 kharif seasons to know the right time of incorporation of groundnut crop residue and its subsequent effect on the following rice crop. The treatments of the experiment were five incorporation time of groundnut crop residue i.e., 12 days before transplanting (12 DBT), 9 DBT, 6 DBT, 3 DBT and 0 DBT of following T. aus rice along with a control (no incorporation of residue). The results showed that yield contributing characters and yield of T. aus rice varied significantly and increased with the increase of incorporation time. But incorporation at 3 days before transplanting performed worst due to seedling mortality by gas injury. The other incorporation time treatments gave identical grain yield (3.69-3.99 t ha-1 in1999 and 3.90-4.10 t ha-1 in 2000) and straw yield (3.89-4.67 t ha-1 in 1999 and 4.00-4.43 t ha-1 in 2000). The average highest grain yield (4.04 t ha-1) was obtained from the treatment 12 DBT.

Key words: Residue effect, Incorporation period, Rice, Yield, Soil fertility.
