Effect of sowing time on varieties of summer groundnut

A field experiment entitled "Effect of sowing time on varieties of summer groundnut" was conducted during the summer season of the year 2022 at the plot number E-5, Regional research station farm, Anand Agricultural University, Anand, Gujarat, India. The experiment was laid out in split plot design with four replications and 9 treatment combinations, where main plot consisted of three different sowing times: 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 aimed to investigate the effects of sowing time and varieties on the growth, yield attributes, yield, quality and economics of summer groundnut.The study assessed plant population, growth parameters: plant height (cm) and dry weight of nodules (mg/plant), plant dry biomass (g/plant) and days of maturity; yield attributes and yield parameters: pods per plant, pod yield (kg/ha) and haulm yield (kg/ha), Shelling (%),Seed index (%) and quality parameters: oil (%) and protein (%) in kernel.The results of the experiment revealed that the sowing time significantly influenced the growth.
