Abstract
Field experiments were conducted at two locations and in two seasons, 1985-86 and 1986-87, to study the effect of split application of nitrogen fertilizer on the growth, yield and protein content of wheat. The treatments tested included an unfertilized control, applying the fertilizer (160 kgN/ha) in one dose at sowing, in two splits at sowing and at tillering, three splits at sowing, tillering and booting, and four splits at sowing, tillering, booting and flowering. The effect of treatments on growth parameters, yield, yield components and protein content was studied. The unfertilized control was significantly the lowest in growth and yield. The tested parameters showed that split application of N fertilizer was superior to the application in one dose. Applying N fertilizer in three equal doses at sowing, tillering and booting gave the highest grain yield of wheat. A fourth split given at the time of flowering increased the protein content of grains.
