Abstract: A study was conducted at the Agricultural College and Research Institute, Madurai to find out the influence on dates of sowing and nitrogen levels on the growth and yield of groundnut cultivar VRI-2 during Rabi crop season 2016. Twelve treatment combinations comprising of four dates of sowing (D1:9th February, D2:19th February, D3: 29th February, and 9th D4: March) and three N levels (Normal dose, 25% more, 25% less) was executed in factorial randomized block design with three replications. The growth parameters like plant height, dry matter production and leaf area index and yield of parameters like pod yield and haulm yield were significantly influenced by the dates of sowing. The highest pod yield and haulm yield were obtained from the plants sown during February 9th, followed by February 19th sowing. The variety VRI-2 recorded the highest pod yield and haulm yield. Delay in sowing reduced the crop duration and subsequently reduced the crop yield. Results of N levels highest influenced were significantly higher growth and yield parameters were influenced by N3: Higher than normal and followed by N1: Normal and lower on nitrogen levels was observed in N2: Lesser than normal.Interaction between dates of sowing and nitrogen levels influenced highest growth and yield parameters significantly were D1: 9thFebruary+ N3: Higher than normal followed by D1:9thFebruary+ N1:Normal and lowest interaction was observed by D1:9thFebruary+N2: Lesser than normal.
