A field experiment was carried out to know the thermal indices of groundnut under rainfed condition in middle Gujarat at Agronomy Farm, Anand Agricultural University, Anand (Gujarat) during 2019 and 2020. Analysis of data showed that groundnut accumulated about 2143.5°C day and 1906°C day GDD, 27293°C days h and 26322°C days h PTU and 9466°C days h and 11648°C days h HTU for obtained better pod yield (2176 kg ha-1 and 1862 kg ha-1) in first date of sowing as compared with second sowing (1976 kg ha-1 and 1592 kg ha-1) and third sowing (1614 kg ha-1 and 1369 kg ha-1) during 2019 and 2020, respectively. Among the varieties, GG 20 accumulated about 2254°C days and 1951°C days GDD, 27293°C days h and 26322°C days h PTU and 9466°C days h and 1164°C days h HTU required for getting higher pod yield (2043 kg ha-1 and 1701 kg ha-1) in comparison with GJG 34 and TAG 37A. Also, results analysis showed that onset of monsoon recorded higher HUE (1.02 kg ha-1 °C day and 0.91 kg ha-1 °C day, respectively) that attributed to higher pod and biomass yield. In varieties, GG 20 recorded higher HUE (0.91 kg ha-1 °C and 0.87 kg ha-1 °C day) and higher pod and biomass yield. Hence, first date of sowing was significantly superior for pod and biomass yield due to better thermal responses, well distributed rainfall and available soil moisture. [ABSTRACT FROM AUTHOR] |
