Abstract

Experiments were conducted at the Department of Agricultural Meteorology, Anand Agricultural University, Anand during the Summer of 2015 and 2016 with four varieties of groundnut (GG-2, GG-20, GJG-31 and TG-26) sown on three different dates to study the effect of weather parameters and agrometeorological indices on pod yield of groundnut. The results of the present investigation indicated that pod yield of groundnut was negatively correlated with maximum, minimum and mean temperature during most of the phenophases except P9 (pod maturity to physiological maturity), where the mean temperature has varied between 32.70C to 35.10C during pod maturity to physiological maturity. In our experiment, we have found that more than 33.90C is required for adequate seed development, resulting in higher test weight and higher pod yield. Agrometeorological indices have a significant and positive correlation with pod yield only during P7 (pod initiation to pod development) phase.
