Abstract

The pattern of dry matter production and its distribution in different plant parts of bunch varieties of groundnut due to variations in time of sowi o and nutrient spray was studied at Agricultural College farm, Dharwad, during the summer season of 1978. with successive delay in date of sowing from 25th January to 24th February the total dry matter production. dry matter accumulation in peds at harvest, rate of dry matter accumulation and leaf area index at early stages increased markedly. The 10th March sowing recorded the lowest total dry matter oroduction 118 77 g/plant) and its accumulation in pods (11,09 g/plant) at har- vest. These variations were caused due to variations in weather conditions like rainfall, temperature, day length, light intensity humidity and sunshine, Dry matter production and its accumulation in pods was highest in TG 3 variety followed by Rs-12, TG-3 also recorded. the highest leaf area index and leaf aren duration at alt the stages of growth and conse- quently it recorded the highest rate of dry matter accumulation at all the stages except at 91 days to harvest.
