An investigation on effect of sowing time on growth, phenology and yield attribute of summer groundnut (Arachis hypogaea L.) was conducted at Agrometeorological Station Farm, School of Forestry and Environment, SHIATS-Deemed-To-Be-University, Allahabad during crop season 2013. Sixteen treatment combinations with four dates of sowing (1st March, 11th March, 21st March and 31st March) and four varieties (HNG-69, R-2 (Girnar-2), HNG-10 and M-13) were tried in split plot design with four replications. The growth parameters, yield attributes and yield in terms of characters like plant population was non-significant and the plant height, number of pods per plants, grain yield and haulm yield were significantly influenced by the dates of sowing. | Effect of sowing time on growth phenology and yield attribute of summer groundnut Arachis hypogaea L. in Allahabad
