abstract
A field experiment was conducted during the summer season of the year 2022 at regional research station farm, Anand Agricultural University, Anand, Gujarat, India to study the effect of sowing time on varieties of summer groundnut. The soil having sandy loam or Goradu type of texture with adequate drainage profile. The experiment was laid out in split plot design with four replications and nine treatment combinations, where main plot consisted of three different sowing time: S1: Second fortnight of January; S2: First fortnight of February; S3: Second fortnight of February and the sub-plot consisted of three different groundnut varieties: TAG 24, TG 37A and GG 34. The study assessed plant population, growth parameters: plant height (cm), Dry weight of root nodules (mg/plant), Plant dry biomass (g/plant) and Days to maturity with yield attributes and yield: pods per plant, seed index (g) and shelling (%) and pod and haulm yield. Quality parameters also recorded as oil and protein content. Sowing on Second fortnight of February resulted in higher plant height, dry weight of root nodules and plant dry biomass. Crop sown at second fortnight of January recorded more days to maturity and the highest pods per plant. It also led to higher pod yield as well as haulm yield. Among the varieties, GG 34 was observed the highest plant height, plant dry biomass, days to maturity, pods per plant and shelling. Variety GG 34 produced the highest pod yield as well as haulm yield. Sowing on second fortnight of January and selecting GG 34 can increase yield and net return in summer groundnut cultivation, providing valuable insights for farmers and researches.
