Effect of dates of sowings on growth and productivity of different cultivars of groundnut (Arachis hypogaea L.)

Abstract

Field experiment was conducted at Agricultural Research Station, Kadiri, ANGRAU to study the influence of sowing windows on growth and yield of groundnut cultivars under rainfed conditions during Kharif season of 2016-17, 2017-18 and 2018-19 on sandy loam soil. Four groundnut cultivars viz., Dharani, Kadiri-6, Kadiri-9 and Kadiri Harithandra were evaluated under four sowing windows viz., first and second fortnights of June and July months. The experiment was laid out in Split plot Design and replicated thrice. The experimental results revealed that, highest mean pod yield was recorded with Kadiri-9 (1866 kg/ha) over the different dates of sowing and it was at par with Kadiri- harithandra (1790 kg/ha). While, among different sowing windows, highest mean pod yield was recorded at 1st fortnight of July (1905 kg/ha) which was at par with 2nd fortnight of June (1804 kg/ha) and significantly superior over the rest of the dates of sowings i.e., 1st fortnight of June and 2nd fortnight of July.
