Abstract
Studies pertaining to effect of split application of nitrogen on growth and yield of wheat was carried out at Agricultural Research Farm of Kunduz University during 2018-19 using RCBD with three replications. Nitrogen by Urea was applied; 50% N as basal + 50% N at tillering, 50% N as basal + 50% N at flowering, 50% N as basal + 25% N at tillering + 25% N at flowering, 33% N as basal + 66% N at tillering, 33% N as basal + 66% N at flowering, 33% N at basal + 33% N at tillaring +33% N at flowering. The results showed that split application of nitrogen in 2 split (33% N as basal + 66% N at tillering) increases the all growth parameters [height of plant (105.25 cm), number of tillers (6.16 tiller plant-1), spicks (5.63 spick plant-1) and spikelet per spick (16.66 spikelet spick-1), the yield and yield component; 1000 grain weight (34.60 g), grain yield (5208.22 kg ha-1) and straw yield (8853.98 kg ha-1) increases with 33% N as basal + 33% N at tillering + 33% N at flowering.
