Abstract:
Field experiment was conducted during Kharif season 2021 at Crop Research Farm, Department of Agronomy, SHUATS, Allahabad, (U.P.) to study the influence of sowing windows on growth and yield of groundnut cultivars under rainfed conditions during Kharif season of 2020-21 on sandy loam soil. Three groundnut cultivars viz., GJG-32, GG-14, TAG 37A were evaluated under three sowing windows viz., second fortnight July, first and second fortnight of August months. The experiment was laid out in Randomized Block Design. There were nine treatments each replicated thrice. From the results, it was observed that the growth parameters viz., plant height (63.14 cm), dry weight (55.0 g/plant), number of nodules per plant (50.1), dry matter accumulation (1833.41g/m²) were recorded highest in the treatment 2 was recorded with GJG-32+20^th July. The yield parameters and yield viz., No. of pods per plant (31.72), shelling percentage (69.65%), Seed yield (2.91 t/ha), Haulm yield (4.77 t/ha),Seed index (34.07 g),No. of kernels per plant (1.93).The experimental results revealed that, highest mean pod yield was recorded with GJG-32 (2.91 t/ha) over the different dates of sowing and it was at par with GG-14 (2.81 t/ha).
